| 1 | Paleostructural geomorphology of the Paleozoic central uplift belt and its constraint on the development of depositional facies in the Tarim Basin显示文摘Inclined eastward and consisting of the Hetianhe, Hetianhedong, Tazhong paleouplifts and Bachu paleoslope, the central paleouplift belt in the Tarim Basin was a large composite paleouplift and paleoslope belt with complicated palaeogeomorphic features during the Middle to early Late Ordovician. A number of paleostructural geomorphic elements have been identified in the paleouplift belt and surrounding areas, such as the high uplift belts, the faulted uplift platforms, the marginal slopes and slope break zones flanking the paleouplift belt, the surrounding shelf slopes or low relief ramps, the shelf slope break zones and deep basin plains. They exerted great influence on the development of paleogeography of the basin. The marginal slopes and slope break zones flanking the uplift belt constrained the formation and deposition of the high-energy facies including reefal and shoal deposits during the Late Ordovician, which comprise the major reservoirs of the Lower Paleozoic in the basin. Toward the end of the Ordovician, the Tazhong paleouplift hinged westward and became a westward-dipped nose as the southeastern margin of the basin was strongly compressed and uplifted. The tectono-paleogeomorphic framework of the central northern basin during the Early Silurian and the Late Devonian to Early Carboniferous changed remarkably in topography from the initial low in east and high in west to high in northeast and low in southwest. The major paleogeomorphic elements developed in these periods included the strong eroded uplift high, the uplift marginal slope, the gentle ramp of the depression margin and the depression belt. The sandstones of the lowstand and the early transgressive systems tracts were deposited along the uplift marginal slopes and the gentle ramps of the depressions comprise the prolific reservoirs in the basin. The study indicates that the distribution patterns of the unconformities within the basin are closely related to the paleogeomorphic features and evolution of the paleouplift belt. From the high uplift belt to the depression, we found the composed unconformity belts at the high uplift, the truncated and onlap triangular unconformity belts along the uplift marginal slopes, the minor angular unconformity or discontinuity belts along the transitional zones from the uplift marginal slopes to depression and the conformity belt in the central depression. The truncated and the onlap triangular unconformity belts are the favorable zones for the formation of stratigraphic trap reservoirs. | LIN ChangSong YANG HaiJun LIU JingYan PENG Li CAI ZhenZhong YANG XiaoFa YANG YongHeng | 2009 | Science China Earth Sciences2009，52，6： | 52 |
| 2 | Gene expression profiling of rat livers with Yin-deficiency-heat syndrome显示文摘OBJECTIVE: To explore the nature of 'Yin internal heat caused byYin-deficiency,' in terms of the theory of Traditional Chinese Medicine, by studying energy metabolism in rats with Yin-deficiency-heat syndrome and analyzing the gene expression profile of their livers. METHODS: A Yin-deficiency-heat syndrome model was induced in rats using three Chinese medicinal herbs. Glycogen and triglycerides in blood plasma, and the enzyme activity of ATP in livers were measured colorimetrically. Triiodothyronine (T3 ), thyroxine (T4 ), and thyroid stimulating hormone levels in blood plasma were also measured with enzyme linked immunosorbent assay. The gene expression profile of livers was detected with gene chip analysis. Differentially expressed genes were screened out and classified according to Gene Ontology. The accuracy of results were examined with reversetranscription-polymerase chain reaction. RESULTS: Compared with the control group, body weight (P<0.05) and hepatic glycogen (P<0.05) were significantly lower in the Yin-deficiency-heat syndrome group. Moreover, toe temperature (P< 0.01) and triglyceride (P<0.05), Na+ -K+ -ATPase (P< 0.01), Mg2+ -ATPase (P<0.01), T3 (P<0.05), and T4 (P< 0.01) levels were significantly higher. There were 99 differentially expressed genes in livers from the Yin-deficiency-heat syndrome group. Genes were mainly related to sterol synthesis (Pc=0.0392), defense response (Pc=0.0448), and sterol metabolism (Pc=0.0533). CONCLUSION: Abnormal expression genes in rats with Yin-deficiency-heat syndrome prompted the synthesis and metabolism of cholesterol, increased energy consumption, and reduced defense response. This gene expression might be the molecular mechanism underlying 'internal heat caused by Yin-deficiency' in the rats with Yin-deficiency-heat syndrome. | Bingbing Han Shijun Wang Lin Li YuanWang Haijun Zhao | 2013 | Journal of Traditional Chinese Medicine2013，33，3： | 8 |
| 3 | Depositional architecture of the late Ordovician drowned carbonate platform margin and its responses to sea-level fluctuation in the northern slope of the Tazhong region, Tarim Basin显示文摘The Tazhong Uplift of the late Ordovician is a drowned rimmed carbonate platform. The carbonate rock of the late Ordovician Lianglitage Formation in the northern slope of the Tazhong region is one of the significant petroliferous intervals. Based on petrofacies, depositional cycles, natural gammaray spectrometry and carbon/oxygen isotope data from the Lianglitage Formation, one 2nd-order, three 3rd-order and several 4th-order sequences have been recognized, and the late Ordovician relative sealevel fluctuation curve has been established. The sequences O 3 l-1 and O 3 l-2 on the platform are composed of highstand and transgressive systems tracts, but lack the lowstand systems tract. The sequence O 3 l-3 is a drowning sequence. The sequence O 3 l-1 overlapped the eroded slope and pinched out to the northwest and landward. The highstand systems tract in the sequence O 3 l-2 consists of low-angle sigmoid and high-angle shingled progradation configuration. Major sedimentary facies of the Lianglitage Formation include reef and shoal in the platform margin and lagoon, which can be subdivided into coral-sponge-stromatoporoid reef complex, sand shoal, lime mud mound, and intershoal sea. Reefs, sand shoals and their complex are potential reservoir facies. The reefs and sand shoals in the sequence O 3 l-1 developed in the upper of its highstand systems tract. In the sequence O 3 l-2, the highstand systems tract with an internal prograding configuration is a response to the lateral shifting of the complex of reef and sand shoal. The transgressive systems tract, in particular the sand shoals, developed widely on the slope of the platform margin and interior. The reefs in the sequence O 3 l-3 migrated towards high positions and formed retrograding reefs in the western platform and low relief in the platform interior. Basinward lateral migration of the reefs and pure carbonate rock both characterize highstand systems tract and show that the rise of the relative sea-level was very slow. Shingled prograding stacking pattern of the 4th-order sequences and reefs grow horizontally, which represents the late stage of highstand systems tract and implies relative sealevel stillstand. Reefs migrating towards high land and impure carbonate rock both indicate transgressive systems tract and suggest that the relative sea-level rose fast. Erosional truncation and epidiagenetic karstification represent a falling relative sea-level. The relative sea-level fluctuation and antecedent palaeotopography control the development and distribution of reef complexes and unconformity karst zones. Currently, the composite zone of epidiagenetic karstic intervals and high-energy complexes of reefs and sand shoals with prograding configuration is an important oil and gas reservoir in the northern slope of the Tazhong carbonate platform. | Yang Xiaofa Lin Changsong Yang Haijun Han Jianfa Liu Jingyan Zhang Yanmei Peng Li Jing Bing Tong Jianyu Wang Haiping Li Huanpu | 2010 | Petroleum Science2010，7，3： | 8 |
| 4 | Preparation of large-size Al_(2)O_(3)/GdAlO_(3)/ZrO_(2)ternary eutectic ceramic rod by laser directed energy deposition and its microstructure homogenization mechanism显示文摘Laser 3D printing based on melt growth has great potential in rapid preparation of Al_(2)O_(3)-based eutectic ce ramics.In this work,la rge-scale Al_(2)O_(3)/GdAlO_(3)/ZrO_(2)ternary eutectic ceramic rod with diameter of 4-5 mm and height higher than 250 mm was additively manufactured by laser directed energy deposition.Especially,heat treatment was applied to eliminate the microstructure heterogeneity in the as-deposited eutectic ceramic,and the microstructure homogenization mechanism was studied in depth.The results indicate that colonies and banded structures completely disappear after the heat treatment,producing a homogeneous network eutectic structure.The microstructure homogenization is revealed to experience three stages of discontinuous coarsening,continuous coarsening and microstructure coalescence.Additionally,it is found that the eutectic spacing linearly increases with the heat treatment time,meaning that the coarsening behavior of the laser 3D-printed Al_(2)O_(3)/GdAlO_(3)/ZrO_(2)eutectic ceramic satisfies well with the Graham-Kraft model. | Haifang Liu Haijun Su Zhonglin Shen Di Zhao Yuan Liu Yinuo Guo Min Guo Jun Zhang Lin Liu Hengzhi Fu | 2021 | Journal of Materials Science & Technology2021，，26： | 5 |
| 5 | Patients with SARS-CoV-2 and HBV coinfection are at risk of greater liver injury显示文摘To date,it remains unclear if severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)co-infection exacerbates liver injury in patients with chronic hepatitis B virus(HBV)infection.In this study,we present a retrospective study of 133 hospitalized confirmed mild coronavirus disease 2019(COVID-19)cases,including 116 patients with COVID-19 with negative serum hepatitis B antigen and 17 HBV inactive carriers with COVID-19.We found that there were no significant differences for the discharge rate or duration of hospitalization be-tween the two groups.However,inactive HBV carriers with SARS-CoV-2 co-infection are at a higher risk of abnormal liver function tests.The enhanced liver injury induced by SARS-CoV-2 and HBV co-infection was identified as the hepatocyte type rather than the cholangiocyte type.Moreover,the inflammatory response,including abnormal lactate dehydrogenase,D-dimer and interleukin-6 production,may contribute to this injury following SARS-CoV-2 co-infection.Collectively,SARS-CoV-2 and HBV co-infection exacerbates liver function of the pa-tients with COVID-19. | Yong Lin Jun Yuan Quanxin Long Jieli Hu Haijun Deng Zhenyu Zhao Juan Chen Mengji Lu Ailong Huang | 2021 | Genes & Diseases2021，8，4： | 5 |

| 8 | Distribution control and formation mechanism of gas inclusions in directionally solidified Al2O3-Er3Al5O12-ZrO2 ternary eutectic ceramic by laser floating zone melting显示文摘Distribution control and formation mechanism of gas inclusions formed in directionally solidified Al2O3-Er3Al5O12-ZrO2 eutectic ceramic rods are explored during laser floating zone melting. In atmospheric environment, highly-dense bubble-free eutectic rods are well fabricated at low solidification rate(<25μm/s). Gas inclusions form intermittently when the solidification rate is in the range of 25-50 μm/s,but produce continuously at higher solidification rates(100-200 μm/s). The gas inclusions exhibit an elongated finger-like pattern along the growth direction, which of the maximum value of diameter first increases and then decreases with increasing the solidification rate. Meanwhile, the volume fraction of gas inclusions increased gradually with the solidification rate. Based on the effect of surface tension gradient, heterogeneous nucleation of gas bubbles is evaluated to be the primary formation mechanism of gas inclusions. | Haijun Su Yuan Liu Qun Ren Zhonglin Shen Haifang Liu Di Zhao Guangrao Fan Min Guo Jun Zhang Lin Liu Hengzhi Fu | 2021 | Journal of Materials Science & Technology2021，，7： | 4 |
| 9 | Exosomes derived from 3D-cultured MSCs improve therapeutic effects in periodontitis and experimental colitis and restore the Th17 cell/Treg balance in inflamed periodontium显示文摘Although mesenchymal stem cell-derived exosomes(MSC-exos)have been shown to have therapeutic effects in experimental periodontitis,their drawbacks,such as low yield and limited efficacy,have hampered their clinical application.These drawbacks can be largely reduced by replacing the traditional 2D culture system with a 3D system.However,the potential function of MSC-exos produced by 3D culture(3D-exos)in periodontitis remains elusive.This study showed that compared with MSC-exos generated via 2D culture(2D-exos),3D-exos showed enhanced anti-inflammatory effects in a ligature-induced model of periodontitis by restoring the reactive T helper 17(Th17)cell/Treg balance in inflamed periodontal tissues.Mechanistically,3D-exos exhibited greater enrichment of miR-1246,which can suppress the expression of Nfat5,a key factor that mediates Th17 cell polarization in a sequence-dependent manner.Furthermore,we found that recovery of the Th17 cell/Treg balance in the inflamed periodontium by the local injection of 3D-exos attenuated experimental colitis.Our study not only showed that by restoring the Th17 cell/Treg balance through the miR-1246/Nfat5 axis,the 3D culture system improved the function of MSC-exos in the treatment of periodontitis,but also it provided a basis for treating inflammatory bowel disease(IBD)by restoring immune responses in the inflamed periodontium. | Yong Zhang Jiayao Chen Haijun Fu Shuhong Kuang Feng He Min Zhang Zongshan Shen Wei Qin Zhengmei Lin Shuheng Huang | 2021 | International Journal of Oral Science2021，13，4： | 4 |
| 10 | Infrared drying kinetics and moisture diffusivity modeling of pork显示文摘This study investigated the drying kinetics of pork slice in infrared drying condition.Drying temperature,slice thickness and initial moisture content were selected as influencing factors on the drying characteristics and drying rate of pork slice.Drying curves obtained from the experimental data were fitted to semi theoretical and/or empirical thin layer drying models.The effects of drying temperature and slice thickness on the model constants were evaluated by the multiple regression method.All the models were compared according to three statistical indexes,i.e.,root mean square error,chi-square and modeling efficiency.The slice thickness,drying temperature and initial moisture content have significant influences on the effective diffusivity coefficient of pork.The results showed that the drying rate of pork slices increased with the increases of drying temperature and initial moisture content.The decreases of slice thickness also led to an increase of drying rate.The Henderson and Pabis model can best describe the drying curves of pork. | Ling Jing Teng Zhaosheng Lin Haijun Wen He | 2017 | International Journal of Agricultural and Biological Engineering2017，10，3： | 3 |
| 11 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |

| 13 | First results on ^(76)Ge neutrinoless double beta decay from CDEX-1 experiment显示文摘We report the first results on ^(76)Ge neutrinoless double beta decay from stage one of the China dark-matter experiment(CDEX).A p-type point-contact high-purity germanium detector with a mass of 994 g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304 kg d has been analyzed over a wide spectral band from 500 keV to 3 MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039 MeV energy range. The half-life of ^(76)Ge neutrinoless double beta decay derived based on this result is T^(0ν)1/2>6.4×10^(22) yr(90% C.L.). An upper limit on the effective Majorana-neutrino mass of 5.0 eV has been achieved. | Li Wang Qian Yue KeJun Kang JianPing Cheng YuanJing Li TszKing Henry Wong ShinTed Lin JianPing Chang JingHan Chen QingHao Chen YunHua Chen Zhi Deng Qiang Du Hui Gong Li He QingJu He JinWei Hu HanXiong Huang TengRui Huang LiPing Jia Hao Jiang HauBin Li Hong Li JianMin Li Jin Li Jun Li Xia Li XueQian Li YuLan Li FongKay Lin ShuKui Liu Hao Ma JingLu Ma XingYu Pan Jie Ren XiChao Ruan ManBin Shen Vivek Sharma Lakhwinder Singh Manoj Kumar Singh Manoj Kumar Singh Arun Kumar Soma ChangJian Tang WeiYou Tang ChaoHsiung Tseng JiMin Wang Qing Wang ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue LiTao Yang SongWei Yang Nan Yi ChunXu Yu HaiJun Yu WeiHe Zeng XiongHui Zeng Zhi Zeng Lan Zhang YunHua Zhang MingGang Zhao Wei Zhao JiFang Zhou ZuYing Zhou JingJun Zhu WeiBin Zhu ZhongHua Zhu | 2017 | Science China(Physics,Mechanics & Astronomy)2017，60，7： | 3 |
| 14 | Application of a novel redox-active electrolyte in MnO_2-based supercapacitors显示文摘This paper reports a novel strategy for preparing redox-active electrolyte through introducing a redox-mediator(p-phenylenediamine,PPD) into KOH electrolyte for the application of ball-milled MnO 2-based supercapacitors.The morphology and compositions of ball-milled MnO 2 were characterized using scanning electron microscopy(SEM) and X-ray diffraction(XRD).The electrochemical properties of the supercapacitor were evaluated by cyclic voltammetry(CV),galvanostatic charge-discharge(GCD),and electrochemical impedance spectroscopy(EIS) techniques.The introduction of p-phenylenediamine significantly improves the performance of the supercapacitor.The electrode specific capacitance of the supercapacitor is 325.24 F g-1,increased by 6.25 folds compared with that of the unmodified system(44.87 F g-1) at the same current density,and the energy density has nearly a 10-fold increase,reaching 10.12 Wh Kg-1.In addition,the supercapacitor exhibits good cycle-life stability. | YU HaiJun WU JiHuai FAN LeQing LIN YouZhen CHEN ShuHong CHEN Yuan WANG JiangLi HUANG MiaoLiang LIN JianMing LAN Zhang HUANG YunFang | 2012 | Science China Chemistry2012，55，7： | 3 |
| 15 | Improved method for prediction of milled rice moisture content based on Weibull distribution显示文摘The loss on drying method,which is regarded as the standard method of rice moisture content analysis,provides the most reliable results but is both labor intensive and time consuming.In order to improve the detection efficiency of the loss on drying method,this study investigated the drying characteristics of milled rice and developed an information fusion algorithm with which to predict milled rice moisture content based on the Weibull distribution and Levenberg-Marquardt(LM)algorithm.Application of the Weibull distribution model was investigated regarding its description of the drying kinetics of milled rice during infrared drying.An adaptive mechanism was applied to algorithm design,with the starting point of the estimation algorithm determined by calculating the drying rate at each measuring point,and the end-point distinguished using a two-level threshold algorithm.The calculated results were then compared with the measured data regarding the infrared drying of milled rice.For milled rice samples varying in moisture content from 14.44%-17.67%(dry basis),the relative error between predicted and observed values ranged 0.0037-0.0589,with a reduction in test time of 50.71%-67.87%. | Jing Ling Zhaosheng Teng Haijun Lin | 2018 | International Journal of Agricultural and Biological Engineering2018，11，3： | 3 |
| 16 | Phase growth patterns for Al_(2)O_(3)/GdAlO_(3)eutectics over wide ranges of compositions and solidification rates显示文摘Phase selection and growth characteristics of directionally solidified Al_(2)O_(3)/GdAlO_3(GAP)faceted eutectic ce ramics are investigated over wide ranges of compositions and solidification rates to explore the eutectic coupled zone.Through the obse rvation of the quenched solid-liquid interface,the competitive growth of primary faceted Al_(2)O_(3)phase,prima ry non-faceted GAP phase and Al_(2)O_(3)/GAP eutectic with diffe rent morphologies is detected.Microstructure transitions from wholly eutectic to primary Al_(2)O_(3)(GAP)dendrite plus eutectic and then to wholly eutectic are found in Al_(2)O_(3)-2 O mol%Gd_(2)O_(3)hypoeutectic(Al_(2)O_(3)-26 mol%Gd_(2)O_(3)hypereutectic)ceramics with the increase of solidification rate.The dendrite growth of faceted Al_(2)O_(3)and non-faceted GAP phases are well predicted by KGT model,which have introduced appro p riate dimensionless supersaturationΩto characterize the anisotropic growth of dendrites.Based on the maximum interface temperature criterion,the competitive growth of primary phase and eutectic is analyzed theoretically and the predicted coupled zone of Al_(2)O_(3)/GAP eutectic ceramics is in good agreement with the experimental results.Besides,the influence of microstructure with these different morphologies on the flexural strength of Al_(2)O_(3)/GAP eutectic ceramics is studied. | Weidan Ma Jun Zhang Haijun Su Guangrao Fan Min Guo Lin Liu Hengzhi Fu | 2021 | Journal of Materials Science & Technology2021，，6： | 3 |
| 17 | Coupling phase field with creep damage to study γ’evolution and creep deformation of single crystal superalloys显示文摘A phase-field model coupling with elastoplastic de fo rmation and creep damage has been built to study the micro structural evolution and deformation behavior for Ni-Al single crystal alloy during the whole creep processing.The relevant experiments were conducted to verify the model validity.The simulation re sults show that under the tensile creep at 1223 K/100 MPa,cubic γ’phases coarsen along the direction parallel to the axis of tensile stress during the first two creep stages;and spindle-shaped and wavy γ’phases are fo rmed during tertiary creep,similar to the experimental results.The evolution mechanism of γ’phases is analyzed from the perspective of changes of stress and strain fields.The'is land-like'γ phase is observed and its formation mechanism is discussed.With the increase of creep stress,the directional coarsening of γ’phase is accelerated,the steady-state creep rate is increased and the creep life is decreased.The comparison between simulated and experimental creep curves shows that this phase-field model can effectively simulate the performance changes during the first two creep stages and predict the influence of creep stresses on creep properties.Our work provides a potential approach to synchronously simulate the creep microstructure and property of superalloys strengthened by γ’precipitates. | Min Yang Jun Zhang Weimin Gui Songsong Hu Zhuoran Li Min Guo Haijun Su Lin Liu | 2021 | Journal of Materials Science & Technology2021，，12： | 3 |
| 18 | Interface science in polymer-based composite solid electrolytes in lithium metal batteries显示文摘Solid-state lithium metal batteries(SSLMBs)have attracted considerable attention as one of the most promising energy storage systems owing to their high safety and energy density.Solid electrolytes,particularly polymer-based composite solid electrolytes(CSEs),are considered promising electrolyte candidates for SSLMBs.However,theirwide application is inhibited by various electrochemical issues,such as low ionic conductivity,the growth of lithium dendrites,and poor cycling stability,which are related to interface issues within SSLMBs.In this review,the parameters related to various interfaces in the CSE of SSLMBs,including the interfaces between the polymer matrix and inorganic fillers,between the CSEs and the cathode,and between the CSEs and the lithium metal anode,are examined.Relevant issues and corresponding remediation strategies are proposed.Finally,future perspectives based on interfacial engineering and the characterization of polymer/inorganic filler interactions are proposed for building high-performance CSEs for use in SSLMBs. | Lingqiao Wu Yongtao Wang Xianwei Guo Peipei Ding Zhiyuan Lin Haijun Yu | 2022 | SusMat2022，2，3： | 2 |

| 20 | Convergence Analysis of anUnconditionally Energy Stable Linear Crank-Nicolson Scheme for the Cahn-Hilliard Equation显示文摘Efficient and unconditionally stable high order time marching schemes are very important but not easy to construct for nonlinear phase dynamics.In this paper,we propose and analysis an efficient stabilized linear Crank-Nicolson scheme for the Cahn-Hilliard equation with provable unconditional stability.In this scheme the nonlinear bulk force are treated explicitly with two second-order linear stabilization terms.The semi-discretized equation is a linear elliptic systemwith constant coefficients,thus robust and efficient solution procedures are guaranteed.Rigorous error analysis show that,when the time step-size is small enough,the scheme is second order accurate in time with a prefactor controlled by some lower degree polynomial of 1/#.Here#is the interface thickness parameter.Numerical results are presented to verify the accuracy and efficiency of the scheme. | Lin Wang Haijun Yu | 2018 | Journal of Mathematical Study2018，51，1： | 2 |
