| 1 | A unified implicit scheme for kinetic model equations. Part I. Memory reduction technique显示文摘A memory reduction technique is proposed for solving stationary kinetic model equations. As implied by an integral solution of the stationary kinetic equation, a velocity distribution function can be reconstructed from given macroscopic variables. Based on this fact, we propose a technique to reconstruct distribution function at discrete level, and employ it to develop an implicit numerical method for kinetic equations. The new implicit method only stores the macroscopic quantities which appear in the collision term, and does not store the distribution functions. As a result, enormous memory requirement for solving kinetic equations is totally relieved. Several boundary conditions, such as, inlet, outlet and isothermal boundaries, are discussed. Some numerical tests demonstrate the validity and efficiency of the technique.The new implicit solver provides nearly identical solution as the explicit kinetic solver, while the memory requirement is on the same order as the Navier–Stokes solver. | Songze Chen Chuang Zhang Lianhua Zhu Zhaoli Guo | 2017 | Science Bulletin2017，62，2： | 7 |
| 2 | Interactive effects of understory removal and fertilization on soil respiration in subtropical Eucalyptus plantations显示文摘Aims It has been well recognized that understory vegetation plays an important role in driving forest ecosystem processes and functioning.In subtropical plantation forests,understory removal and fertiliza-tion have been widely applied;however,our understanding on how understory removal affects soil respiration and how the process is regulated by fertilization is limited.Here,we conducted an under-story removal experiment combined with fertilization to evaluate the effects of the two forest management practices and their inter-actions on soil respiration in subtropical forest in southern China.Methods The study was conducted in a split-plot design with fertilization as the whole-plot factor,understory removal as the subplot factor and block as the random factor in subtropical Eucalyptus plantations.In total,there were four treatments:control with unfertilized and intact understory(CK),understory removal but without fertilization(UR),with fertilization but without understory removal(FT)and with fertilization+understory removal(FT+UR).Eucalyptus above-and belowground biomass increment,fine root biomass,soil tempera-ture,soil moisture and soil respiration were measured in the present study.understory respiration(Ru)was quantified in different ways:Ru=RCK−Ru or Ru=RFT−R(FT+u);fertilization increased soil respiration(RFI)was also quantified in different ways:RFI=RFT−RCK or RFI=R(FT+u)−Ru.Important Findingsover a 2-year experiment,our data indicate that understory removal significantly decreased soil respiration,while fertilization increased soil respiration.understory removal decreased soil respiration by 28.8%under fertilization,but only 15.2%without fertilization.Fertilization significantly increased soil respiration by 23.6%with the presence of understory vegetation,and only increased by 3.7%when understory was removed,indicating that fertilization increased soil respiration mainly by increasing the contribution of the understory.our study advances our understanding of the interactive effects of understory management and fertilization on soil respiration in subtropical plantations. | Songze Wan Chenlu Zhang Yuanqi Chen Jie Zhao Xiaolin Zhu Jianping Wu Lixia Zhou Yongbiao Lin Zhanfeng Liu Shenglei Fu | 2015 | Journal of Plant Ecology2015，8，3： | 6 |
| 3 | Effects of a novel bimetallic catalytic biofilter-based pretreatment technique on the form of ultrafiltration membrane fouling显示文摘Pretreatments of influents using bimetallic catalytic biofilter(BC-biofilter)can help reduce transmembrane pressures.For ultrafiltration membranes coupled with a conventional biofilter pretreatment,the cake layer resistance accounts for 25.0%of the total resistance.However,for those coupled with BC-biofilter pretreatment,the cake layer resistance accounts only for 12.5%of the total resistance.Confocal laser scanning microscopy is employed to determine the porosity of cake layer.It is found that ultrafiltration membranes with BC-biofilter pretreatment show a cake layer porosity of up to 0.56 or greater,whereas those with a conventional biofilter pretreatment exhibit a cake layer porosity of only 0.36.This is because micro-flocculation occurs in the effluents of BC-biofilter.The flocs generated through flocculation deposit on membrane surfaces to create highly porous cake layer.Moreover,catalytic reduction can increase the zeta potentials of the biofilter effluents.This makes the deposition of colloidal particles and flocs on membrane surfaces difficult under electrostatic repulsion.Simultaneously,micro-flocculation after BC-biofilter pretreatment can remove colloidal particles with particle sizes of200–350 nm in water.This can effectively prevent the blockage of ultrafiltration membrane pores.Furthermore,compared to conventional biofilter,BC-biofilter pretreatment can more effectively reduce the number of colloidal particles and the van der Waals forces of ultrafiltration membranes.They can also change the action directions of electric double layers and thereby mitigate ultrafiltration membrane fouling. | Songze Hao Xuehui Zhao Hongwei Zhang Yun Wu Cheng Fang Xujia Wang | 2020 | Chinese Journal of Chemical Engineering2020，28，10： | 2 |

| 7 | Electrospinning of Biomaterials for Vascular Regeneration显示文摘Cardiovascular diseases have been the leading cause of morbidity and mortality in the world recently.With the growing aging population accompanied by chronic diseases,such as uremia and diabetes,there is an increasing clinical demand for vascular grafts with proper performance.Although some achievements have been made in the development of tissue-engineered vascular grafts composed of natural and synthetic polymeric materials or decellularized vessels,clinical applications with a diameter of less than 6 mm are still principally derived from autografts,such as autologous saphenous veins.Many challenges remain in antithrombosis,rapid endothelialization,modulating the inflammatory response and inhibition of intimal hyperplasia and calcification.In the review,recent progress in the electrospinning of biodegradable polymers for vascular regeneration are summarized,especially from the view of biomechanical factors.Hybrid vascular grafts consisting of natural and synthetic polymers with multicomponent,di-or tri-layers are focused in order to provide novel experiences in biomaterials for applications in this field. | BAI Shan ZHANG Xiangyu ZANG Leilei YANG Songze CHEN Xiaoqi YUAN Xiaoyan | 2021 | Chemical Research in Chinese Universities2021，37，3： | 1 |
| 8 | The decoupling between gas exchange and water potential of Cinnamomum camphora seedlings during drought recovery and its relation to ABA accumulation in leaves显示文摘气候变化将改变降雨格局,从而导致极端干旱事件增多。然而,树木如何协调生理和生化响应来应对干旱-恢复的机制仍不清楚。本研究探讨了干旱-恢复过程中树木生理与生化特征的耦联关系。我们首先将香樟(Cinnamomum camphora)盆栽幼苗种植在水分充足的条件下,然后通过停止浇水以达到干旱处理的目的。当幼苗胁迫至轻度干旱(气孔关闭)和中度干旱(ψxylem=−1.5 MPa)时,分别对其进行复水处理。在干旱及复水4天过程中,我们测定了香樟叶片水势、气体交换、脱落酸以及非结构性碳水化合物的变化规律。我们发现干旱强度在很大程度上决定了香樟的生理与生化响应,并影响其干旱后恢复。轻度干旱导致气孔关闭,并引起叶片脱落酸累积和水势下降,而中度干旱可进一步引起叶片脯氨酸累积和非结构性碳水化合物的变化。干旱强度的增加会导致气体交换恢复滞后,但对水势的恢复无显著影响。另外,干旱与复水过程中水势与气体交换之间的关系存在较大差异:即干旱过程中水势与气体交换存在很强的耦联关系,而这种耦联关系在复水过程中并不存在,其主要原因是由于叶片脱落酸累积,从而延缓了气孔导度的恢复。综上,本研究结果表明,脱落酸可能是导致香樟旱后气孔导度恢复滞后的主要影响因素。此外,干旱强度对树木生理和生化的恢复具有显著影响。 | Honglang Duan Defu Wang Xiaohua Wei Guomin Huang Houbao Fan Shuangxi Zhou Jianping Wu Wenfei Liu David TTissue Songze Wan | 2020 | Journal of Plant Ecology2020，13，6： | 1 |

| 13 | Microstructure, Texture, and Hardness Evolutions of Al-Mg-Si-Cu Alloy during Annealing Treatment显示文摘Microstructure, texture and hardness evolutions of Al-Mg-Si-Cu alloy during annealing treatment were studied by microstructure, texture and hardness characterization in the present study. The experimental results show that microstructure, texture and hardness will change to some extent with the increase of annealing temperature. The microstructure transforms from the elongated bands to elongated grains first, and then the grains grow continuously. The texture transforms from the initial deformation texture β fiber to recrystallization texture mainly consisting of CubeND {001}<310> and P {011}<122> orientations first, and then the recrystallization texture may be enhanced continuously as a result of the grain growth. Hardness decreases slowly at first, and then decreases sharply and increases significantly finally. Besides, the particle distributions also have great changes. As the annealing temperature increases, they increase firstly as a result of precipitation, and then gradually disappear as a result of dissolution. Finally, the effect of annealing temperature on microstructure, texture and hardness evolutions is discussed. | 汪小锋 MA Cunqiang MA Pengcheng ZHOU Songze WANG Yonggang | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，6： | 1 |
