| 1 | Paleogene-Neogene stratigraphic realm and sedimentary sequence of the Qinghai-Tibet Plateau and their response to uplift of the plateau显示文摘Based on the data of 1:250000 geological mapping completed by CGS and the previous literature of the Cenozoic strata, 98 remnant basins and 5 stratigraphic realms with 13 stratigraphic subrealms have been recognized on the Qinghai-Tibet Plateau and its adjacent area. Through the research of the types of remnant basins, tectonic setting, stratigraphic sequence and sedimentary characteristics, contact relationship between the strata, the formation time and evolution history of sediments, we divided the uplift process and sedimentary response of the Qinghai-Tibet Plateau into 3 stages and 8 sub-stages, namely, subduction-collision uplift stage (65-34 Ma) with three sub-stages, intercontinental convergence and compressive uplift stage (34-13 Ma) with three sub-stages, and intercontinental isostatic adjustment uplift stage (since 13 Ma) with two sub-stages. | ZHANG KeXin WANG GuoCan JI JunLiang LUO ManSheng KOU XiaoHu WANG YueMing XU YaDong CHEN FenNing CHEN RuiMing SONG BoWen ZHANG JianYu LIANG YinPing | 2010 | Science China Earth Sciences2010,53,9: | 49 |
| 2 | Cenozoic sedimentary records and geochronological constraints of differential uplift of the Qinghai-Tibet Plateau显示文摘Geological mapping data (1:250000) in the Qinghai-Tibet Plateau and its adjacent regions reveal the sediment sequences, distribution and tectonic evolution of the 92 Tertiary remnant basins. Southern Tibet and the Yecheng area in Xinjiang, located at southern and northwestern margins of the Qinghai-Tibet Plateau, respectively, were parts of the Neo-Tethys remnant sea in the Paleogene. In southern Tibet, both the subabyssal and abyssal sequences occur at the Gyangze, Saga, Guoyala, and Sangmai areas. The deep-water facies successions outcrop in the west, whereas the shallow-water facies sequences in the east, indicating the east to the west retreat of the Neo-Tethys Ocean. The retreat of the Neo-Tethys Ocean in the east was contributed to the earlier tectonic uplift of the eastern Qinghai-Tibet Plateau. The uplift process of the Plateau from the Late Cretaceous to Pliocene is described as follows: During the Late Cretaceous, tectonic uplift of the Qinghai-Tibet Plateau occurred in the northeastern part and the configuration of the Qinghai-Tibet Plateau was characterized by rise in the northeast and depression in the west. In the Paleocene-Eocene interval, the Tengchong-Baingoin and Kuyake-Golmud areas experienced local tectonic uplifting, the West Kunlun uplift zone broadened easterly, the Qilian uplift zone broadened southerly, and the Songpan-Garzê uplift zone shrank easterly. The Oligocene configuration of the Qinghai-Tibet Plateau was characterized by mountain chains rising along its margins and sedimentary basins in the central part because of tectonic uplifts of the Gangdisê and the Himalaya blocks. Meanwhile, the Kunlun-Altyn-Qilian uplift zones have also broadened southerly and northerly. In contrast, the great uplift zones of the Gangdisê, the Himalaya, the Karakorum, and the Kunlun blocks characterize the paleogeographic contours of the Qinghai-Tibet Plateau during the Miocene-Pliocene. Additionally, the thermochronological data on tectonic uplift events in southern Tibet, West Kunlun Mountains, Altyn Tagh, eastern Tibet, and western Sichuan all suggest that the most intense deformation occurred at 13-8 Ma and since 5 Ma, respectively, corresponding to two great uplift periods in Neogene. As a result, turnover of paleogeographic configuration of the Qinghai-Tibet Plateau occurred during the Neogene, experiencing a change from high contours in the east in the pre-Oligocene to high contours in the west at the end-Pliocene. The uplift of the Qinghai-Tibet Plateau during the Cenozoic was episodic, and the uplifts of various blocks within the Plateau were spatially and chronologically different. | ZHANG KeXin WANG GuoCan CAO Kai LIU Chao XIANG ShuYuan HONG HanLie KOU XiaoHu XU YaDong CHEN FenNing MENG YanNing CHEN RuiMing | 2008 | Science China Earth Sciences2008,51,11: | 31 |
| 3 | The Influence of Phacoemulsification on Corneal Endothelia Cells at Varying Blood Glucose Levels显示文摘Purpose:To investigate the influence of phacoemulsification on corneal endothelial cells in diabetes patients and normal controls. Methods:Phacoemulsification and intraocular lens implantation were performed on 75 patients with diabetic cataract (126 eyes) who were divided into two groups: Trial group 1 (Glu≤6 mmol/L); Trial group 2 (Glu 6-10 mmol/L) and 65 nondiabetic controls (112 eyes).The density and percentage of hexagonal cells and coefficient of variation of the corneal endothelia were measured before surgery and 1 day,1 month and 3 months postoperatively. Results: There was no statistical difference in the density and percentage of hexagonal cells and coefficient of variation of the corneal endothelia prior to phacoemulsification.(P>0.05) between the three groups.The density and percentage of hexagonal cells of the corneal endothelia decreased significantly after surgery in all three groups(P<0.05),while the Coefficient of variation increased in all groups(P<0.05). The rate of loss of corneal endothelial cells in the diabetic groups was significantly higher than for the control group (P<0.05), the percentage of hexagonal cells in the diabetic groups was significantly lower than for the control group (P<0.05), and the coefficient of variation in the diabetic groups was significantly higher than for the control group (P<0.05) at 1 day, 1 month and 3 months post-operatively. There was no statistical difference between the two diabetic groups in terms of these post-operative measurements. Conclusion:The corneal endothelium of diabetic patients is more prone to damage from phacoemulsification. It is advisable to evaluate the corneal endothelium routinely prior to phacoemulsification, particularly in diabetic persons. | RuiMing Yang Xiangyin Sha Mingbing Zeng Yingqian Tan Yu Zheng Feihong Fan | 2011 | Eye Science2011,26,2: | 14 |

| 5 | Surface pollen assemblages of human-disturbed vegetation and their relationship with vegetation and climate in Northeast China显示文摘Pollen assemblages of 53 surface pollen samples from farmlands and wastelands in Northeast China were analyzed. Tree pollen percentages were usually higher than 30%, with Pinus (26.9%), Quercus (0.9%), Betula (0.9%) and Populus (0.7%) as the major types, and herb pollen percentages were usually higher than 50%, with weedy Poaceae (8.7%), Chenopodiaceae (7.1%), Artemisia (1.9%) and Compositae (3.5%) as the major taxa. Thus, the pollen assemblages were consistent with the regional vegetation compositions. However, there were differences in pollen assemblages among regions, especially among different geomorphological units. For example, in the mountains, there were more types of tree pollen and higher total percentages (average 42%) than in other areas, while cereal pollen percentages were lowest (11.2%). In the hills and high plains, herbs made up more than 60% of the pollens, with cereals (average 53.6%) the dominant type. In the low plains, pollen types were similar to those in the hills and high plains, but total pollen concentrations and the proportion of Concentricystes were much higher, while cereal pollen percentages were slightly lower (average 41.6%). Pollen assemblages in different land use types also differed. For example, in farmland, cereal pollen percentages were more than 40% and Chenopodiaceae was usually less than 2.5%, while in wasteland, weedy Poaceae was usually less than 10% and Chenopodiaceae was usually higher than 25%. Total pollen concentrations in farmland (average 3909 grains/g) were much lower than in wasteland (average 15074 grains/g). Redundancy analysis revealed that pollen assemblages were significantly negatively correlated with mean annual temperature (-0.73) and July mean temperature (-0.81) and significantly positively correlated with mean annual precipitation (0.48), indicating that pollen assemblages in the artificial or human-disturbed vegetation reflect regional climate well. Comparison of pollen assemblages in different areas of northern China showed that pollen concentrations reflect the intensities of human impact to some degree. For example, pollen concentrations decrease as human impacts increase in intensity. The cereal pollen proportions in farmland differed by area. In Northeast China, cereal pollen proportions were distinctly higher than in most other areas of northern China, suggesting differences in planting habits and climate. | LI ManYue LI YueCong XU QingHai PANG RuiMing DING Wei ZHANG ShengRui HE ZhiGuo | 2012 | Chinese Science Bulletin2012,57,5: | 10 |
| 6 | Ce-doped LiNi_(1/3)Co_((1/3-x/3))Mn_(1/3)Ce_(x/3)O_2 cathode materials for use in lithium ion batteries显示文摘LiNi1/3Co1/3Mn1/3O2 and Ce-doped LiNi1/3Co1/3Mn1/3O2 cathode materials were synthesized by a co-precipitation method and solid phase synthesis and characterized using X-ray diffraction(XRD) and scanning electron microscopy(SEM).The results indicated that the resultant cathode materials with different Ce content all had a good layer structure and high crystallinity.Electrochemical performance testing of the cathode materials showed that the discharge capacity increased with increasing Ce content while the initial reversible capacity attenuation decreased with Ce doping.When the Ce content of the cathode materials is x=0.2,and the current charge and discharge rate is a constant 0.2 C,the discharge capacity maintained 91% of its initial capacity after cycling 50 times. | ZHANG YingJie XIA ShuBiao ZHANG YanNan DONG Peng YAN Yuxing YANG RuiMing | 2012 | Chinese Science Bulletin2012,57,32: | 8 |
| 7 | The Sedimentary Record in Northern Qaidam Basin and its Response to the Uplift of the South Qilian Mountain at around 30 Ma显示文摘The thick, Eocene to Pliocene, sedimentary sequence in Qaidam Basin at the northern margin of the Tibetan Plateau records the surface uplift history of the northeastern Tibetan plateau. In this study, we present detailed geochemistry, heavy mineral, and clay mineralogy data of the well preserved sedimentary record in the Dahongou section in the northeast of the Qaidam Basin. The results suggest that the sedimentary sequence recorded a 30 Ma young uplift/unroofing event in the northern edge of the Qaidam Basin, which is characterized by high ZTR index value and chlorite content, and low CIW`. The results are consistent with previous sedimentological studies of the Qaidam Basin, which indicated rapid increase of the accumulation rates around 30 Ma. Based on past thermochronological data from the mountains around the Qaidam Basin and the accumulation rates of the Cenozoic basins in the northeastern Tibetan Plateau, we infer a regional uplift and denudation event along the northeastern Tibetan Plateau during early Oligocene (~30 Ma), indicating that the Tibetan Plateau had expanded north-eastward of the study area at that time. | SONG Bowen ZHANG Kexin CHEN Ruiming WANG Chaowen LUO Mansheng ZHANG Jianyu JIANG Shangsong | 2013 | Acta Geologica Sinica(English Edition)2013,87,2: | 8 |
| 8 | Peripheral CD4^(+) T cell signatures in predicting the responses to anti-PD-1/PD-L1 monotherapy for Chinese advanced non-small cell lung cancer显示文摘Limited benefit population of immune checkpoint inhibitors makes it urgent to screen predictive biomarkers for stratifying the patients.Herein,we have investigated peripheral CD4^(+) T cell signatures in advanced non-small cell lung cancer(NSCLC)patients receiving anti-PD-1/PD-L1 treatments.It was found that the percentages of IFN-γand IL-17A secreting naïve CD4^(+) T cells(Tn),and memory CD4^(+) T cells(Tm)expressing PD-1,PD-L1 and CTLA-4 were significantly higher in responder(R)than non-responder(NonR)NSCLC patients associated with a longer progression free survival(PFS).Logistic regression analysis revealed that the baseline IFN-γ-producing CD4^(+) Tn cells and PD-1^(+)CD4^(+) Tm cells were the most significant signatures with the area under curve(AUC)value reaching 0.849.This was further validated in another anti-PD-1 monotherapy cohort.Conversely,high percentage of CTLA-4^(+)CD4^(+) Tm cells was associated with a shorter PFS in patients receiving anti-PD-L1 monotherapy.Our study therefore elucidates the significance of functional CD4^(+) Tn and Tm subpopulations before the treatment in predicting the responses to anti-PD-1 treatment in Chinese NSCLC patients.The fact that there display distinct CD4^(+) T cell signatures in the prediction to anti-PD-1 and anti-PD-L1 monotherapy from our study provides preliminary evidence on the feasibility of anti-PD-1 and anti-PD-L1 combination therapy for advanced NSCLC patients. | Liliang Xia Hui Wang Mingjiao Sun Yi Yang Chengcheng Yao Sheng He Huangqi Duan Weimin Xia Ruiming Sun Yaxian Yao Zhiwei Chen Qiong Zhao Hong Li Shun Lu Ying Wang | 2021 | Science China(Life Sciences)2021,64,10: | 7 |
| 9 | Experimental and molecular dynamic simulation study of perfluorooctane sulfonate adsorption on soil and sediment components显示文摘Soil and sediment play a crucial role in the fate and transport of perfluorooctane sulfonate(PFOS) in the environment. However, the molecular mechanisms of major soil/sediment components on PFOS adsorption remain unclear. This study experimentally isolated three major components in soil/sediment: humin/kerogen, humic/fulvic acid(HA/FA), and inorganic component after removing organics, and explored their contributions to PFOS adsorption using batch adsorption experiments and molecular dynamic simulations. The results suggest that the humin/kerogen component dominated the PFOS adsorption due to its aliphatic features where hydrophobic effect and phase transfer are the primary adsorption mechanism.Compared with the humin/kerogen, the HA/FA component contributed less to the PFOS adsorption because of its hydrophilic and polar characteristics. The electrostatic repulsion between the polar groups of HA/FA and PFOS anions was attributable to the reduced PFOS adsorption. When the soil organic matter was extracted, the inorganic component also plays a non-negligible role because PFOS molecules might form surface complexes on SiO 2surface.The findings obtained in this study illustrate the contribution of organic matters in soils and sediments to PFOS adsorption and provided new perspective to understanding the adsorption process of PFOS on micro-interface in the environment. | Ruiming Zhang Wei Yan Chuanyong Jing | 2015 | Journal of Environmental Sciences2015,27,3: | 6 |
| 10 | Sedimentary Evolution of the Qinghai-Tibet Plateau in Cenozoic and its Response to the Uplift of the Plateau显示文摘We have studied the evolution of the tectonic lithofacies paleogeography of Paleocene-Eocene, Oligocene, Miocene, and Pliocene of the Qinghai-Tibet Plateau by compiling data regarding the type, tectonic setting, and lithostratigraphic sequence of 98 remnant basins in the plateau area. Our results can be summarized as follows. (1) The Paleocene to Eocene is characterized by uplift and erosion in the Songpan-Garzê and Gangdisê belts, depression (lakes and pluvial plains) in eastern Tarim, Qaidam, Qiangtang, and Hoh Xil, and the Neo-Tethys Sea in the western and southern Qinghai-Tibet Plateau. (2) The Oligocene is characterized by uplift in the Gangdisê-Himalaya and Karakorum regions (marked by the absence of sedimentation), fluvial transport (originating eastward and flowing westward) in the Brahmaputra region (marked by the deposition of Dazhuka conglomerate), uplift and erosion in western Kunlun and Songpan-Garzê, and depression (lakes) in the Tarim, Qaidam, Qiangtang, and Hoh Xil. The Oligocene is further characterized by depressional littoral and neritic basins in southwestern Tarim, with marine facies deposition ceasing at the end of the Oligocene. (3) For the Miocene, a widespread regional unconformity (ca. 23 Ma) in and adjacent to the plateau indicates comprehensive uplift of the plateau. This period is characterized by depressions (lakes) in the Tarim, Qaidam, Xining-Nanzhou, Qiangtang, and Hoh Xil. Lacustrine facies deposition expanded to peak in and adjacent to the plateau ca. 18-13 Ma, and north-south fault basins formed in southern Tibet ca. 13-10 Ma. All of these features indicate that the plateau uplifted to its peak and began to collapse. (4) Uplift and erosion occurred during the Pliocene in most parts of the plateau, except in the Hoh Xil-Qiangtang, Tarim, and Qaidam. The continuous uplift and intensive taphrogeny in the plateau divided the original large basin into small basins, deposition of lacustrine facies decreased considerably, and boulderstone accumulated, indicating a response to the overall uplift of the plateau. Here, we discuss the evolution of tectonic lithofacies paleogeography in Cenozoic and its response to the tectonic uplift of the Qinghai-Tibet Plateau in relation to the above characteristics. We have recognized five major uplift events, which occurred during 58-53 Ma, 45-30 Ma, 25-20 Ma, 13-7 Ma, and since 5 Ma. The results presented here indicate that the paleogeomorphic configurations of the Qinghai-Tibet Plateau turned over during the late Miocene, with high elevations in the east during the pre-Miocene switching to high contours in the west at the end of Miocene. | ZHANG Kexin WANG Guocan XU Yadong LUO Mansheng JI Junliang XIAO Guoqiao WANG An SONG Bowen LIANG Yinpin JIANG Shangsong CAO Kai CHEN Fenning CHEN Ruiming YANG Yongfeng | 2013 | Acta Geologica Sinica(English Edition)2013,87,2: | 6 |
| 11 | Surface pollen assemblages as indicators of human impact in the warm temperate hilly areas of eastern China显示文摘Investigation of 78 surface pollen samples from warm temperate hilly areas of eastern China shows that pollen assemblages in areas of different land use are significantly different.Pollen concentrations in wastelands are higher than in plantations;these,in turn,are higher than in farmlands;implying that pollen concentration decreases with increasing human impact.Arboreal pollen dominated by Pinus and Quercus is common in all samples.Herbaceous pollen percentages are higher while shrub pollen,fern spores and fern allies are lower in farmlands than in wastelands.Crop pollen is only detectable in and near farmlands;its percentages and concentrations decrease in wastelands.Cereal and Cruciferae pollen percentages average 16.7% and 6.7% in farmland respectively,but Cereal reduces to less than 3% and Cruciferae to less than 0.5% in nearby wastelands.Principle coordinates analysis and clustering analysis indicate that pollen assemblages from farmlands are distinguishable from those under other vegetation types.Occurrence of Poaceae,Chenopodiaceae,Artemisia,and Compositae pollen and Selaginella sinensis spores are closely related to human activities,and their types and frequencies indicate intensity of human impact.The spatial distribution of crops,Chenopodiaceae,and Artemisia reflects changes in both natural environments and human activities.Percentages of cereal and Cruciferae pollen,for example,increase with decreasing altitude,but decrease with increasing latitude.Understanding pollen assemblages under artificial and human-disturbed vegetation in hilly areas may aid understanding of human impacts on the plains during the early-middle Holocene. | DING Wei PANG RuiMing XU QingHai LI YueCong CAO XianYong | 2011 | Chinese Science Bulletin2011,56,10: | 6 |
| 12 | Study on grid adaptability testing methodology for wind turbines显示文摘The use of wind power has grown rapidly in recent years.Wind power is a clean source of energy,but can have negative impacts on the distribution grid.The influence of large-scale wind power integration on the safe and stable operation of a power system cannot be ignored.It is necessary and urgent to achieve grid adaptability for wind turbines in China.Using a 35 kV/6 MVA grid simulator,the performance of a grid is investigated by simulation.Typical grid disturbances such as voltage deviation,frequency fluctuation,voltage unbalance,and distortion can be simulated.A grid adaptability testing methodology was developed and applied to a doubly fed wind turbine with a focus on analyzing real test data to ascertain its three-phase voltage unbalance adaptability,which was successfully demonstrated.The methodology can also be used to guide other grid adaptability tests. | Shaolin LI Shiyao QIN Ruiming WANG Qing LI Chen CHEN | 2013 | Journal of Modern Power Systems and Clean Energy2013,1,1: | 4 |
| 13 | Ship collision impact on the structural load of an offshore wind turbine显示文摘When a maintenance and operations ship is berthing,there is a chance the ship may collide into the wind turbine.When these ships collide into wind turbine structures,this can result in significant changes to the foundation and structure of the wind turbine.In this paper,the structural load of a 4 MW offshore wind turbine was analyzed during a collision with an operations and maintenance ship.The variations in the wind speeds on hub height,waves,and the sea currents were measured.The dynamic simulation of the wind turbine was carried out using the test data as the input parameters.As a result,the load condition of the turbine without a collision was obtained.Finally,the measured turbine load was compared with the simulation results.This study shows that the collision of the operation and the maintenance ship increases the bending moments at the tower’s bottom and the blade’s roots. | Haikun Jia Shiyao Qin Ruiming Wang Yang Xue Deyi Fu Anqing Wang | 2020 | Global Energy Interconnection2020,3,1: | 4 |
| 14 | Role of Retinal Nerve Fiber Layer Thickness and Optic Disk Measurement by OCT onEarly Diagnosis of Glaucoma显示文摘Purpose:.Glaucoma is an eye disease that can lead to irreversible optic nerve damage and cause blindness. Optical coherence tomography.(OCT) allows an early diagnosis of glaucoma by the measurements of the retinal nerve fiber and optic disc parameters.A retrospective study was designed to analyze the effects of the measurement of the retinal nerve fiber layer(RNFL) thickness and the optic disc tomography by spectraldomain OCT on the early diagnosis of suspected glaucoma and primary open angle glaucoma(POAG).Methods:.This was a clinical case-control study. The RNFL thickness around the optic disc and optic disk tomographic parameters of the control(n=51, 98 eyes), suspected glaucoma(n=81,.146 eyes), and POAG groups(n=55, 106 eyes) were measured by OCT. The parameters included superior, inferior, nasal and temporal mean RNFL thickness,.disc area(DA), cup area(CA), rim area(RA), disc volume(DV),cup volume(CV), rim volume(RV), cup / disc area ratio(CA / DA), rim / disc area ratio(RA / DA), cup / disc volume ratio(CV / DV) and rim / disc volume ratio(RV / DV).Results: Superior, nasal, and mean RNFL parameters, DA,CA,RA, DV, CV, CA / DA, RA / DA, CV / DV and RV / DV significantly differed among three groups by single-factorial ANOVA. Inferior and temporal RNFL thickness significantly differed between the control and POAG groups. No significant difference was observed in RV among three groups. In the POAG group,.the maximum area under the ROC curve(AROC) of mean RNFL thickness was 0.845. The maximum AROC of optic disk parameters was RA / DA(0.998), followed by CA / DA(0.997). The AROC of CA, RA, CV, and DV were all > 0.900.Conclusion:.OCT may serve as a useful diagnostic modality in distinguishing suspected glaucoma from POAG. | Zanmei Hua Qiuyun Fang Xiangyin Sha Ruiming Yang Zuopeng Hong | 2015 | Eye Science2015,30,1: | 3 |

| 17 | N,P-codoped porous carbon derived from chitosan with hierarchical N-enriched structure and ultra-high specific surface Area toward high-performance supercapacitors显示文摘In this work,a facile'carbonization-activation'strategy is developed to synthesize N,P-codoped hierarchical porous carbon.Phosphoric acid is innovatively introduced during the hydrothermal process to achieve in-situ P doping as well as create abundant pores,and the employment of sodamide is of vital importance to simultaneously serve as activating agent and N-source to succeed a high-level N doping.Thus,the obtained samples exhibit a unique three-dimensional hierarchical structure with an ultra-high specific surface area(3646 m^(2)g^(-1))and ultra-high N-doping level(9.81 at.%).Computational analyses confirm that N,P co-doping and higher N content can enhance active sites and widen potential differences of carbon materials to improve their capacitance.The as-prepared carbon materials demonstrate superior electrochemical performances,such as an ultra-high capacitance of 586 Fg^(-1)at 1 Ag^(-1),a superior rate capability of 409 Fg^(-1)at 20 Ag^(-1),and excellent long-term stability of 97%capacitance retention after10,000 cycles in 6 M KOH.Moreover,an assembled symmetric supercapacitor delivers a high energy density of 28.1 Wh kg^(-1)at the power density of 450 W kg^(-1)in 1 M Na_(2)SO_(4),demonstrating a great potential for applications in supercapacitors. | Xipeng Xin Na Song Ruiming Jia Bingnan Wang Hongzhou Dong Shuai Ma Lina Sui Yingjie Chen Qian Zhang Lifeng Dong Liyan Yu | 2021 | Journal of Materials Science & Technology2021,,29: | 2 |
| 18 | Effect of Y_2O_3-MgO Addition on Heterogeneous Precipitation-Thermal Reduction Synthesis and Sintering of FeeMo/Si_3N_4 Powders显示文摘Effect of Y2O3e-MgO addition on heterogeneous precipitation-thermal reduction synthesis and the sintering of Fee Mo/Si3N4 powders has been investigated. It was found that the whiskers-like b-Si3N4, good wettability phases on Si3N4 surface, and high toughness Fe phase appeared in Fee Mo/Si3N4 cermets with Y2O3-MgO additives. The results show that Y2O3-MgO additives can effectively optimize the microstructures of Fee Mo/Si3N4 cermets, and improve the material mechanical properties. Therefore, it indicated that Y2O3-MgO additives can be used for strengthening of sintered cermets, and the dual function of whiskers self-toughening and different metal-composition toughening can be achieved in Fee Mo/Si3N4 cermets with Y2O3-MgO additives. | Ruiming Yin Fubao Ji Qinglin Hou Fusheng Liu Jing Li Linzhang Chen | 2014 | Journal of Materials Science & Technology2014,30,3: | 2 |
