1On Nonlinear Evolution of C-type Instability in Nonparallel Boundary Layers显示文摘进化的过程,特别,非线性的进化,在 nonparallel 的 laminar 狂暴的流动转变的 C 类型不稳定性,边界层借助于一个最新发达的方法被学习,这叫了寓言的稳定性方程(PSE ) 。起始的条件,为非线性的问题很重要,被计算泛音波浪的起始的答案调查,修改 mean-flow-distortion,并且由解决线性 PSE 在起始的车站给 TS 波浪和它的次谐波波浪的起始的价值。有高顺序的精确性的一个数字方法在文章被开发,在 PSE 的关键正规化条件满足,并且非线性的 PSE 高效地被解决并且由空间前进稳定地实现了。在 Blasius 边界层的 C 类型不稳定性的非线性的进化的计算过程在对试验性的结果的好同意,这被显示出。Liu Jixue Tang Dengbin YangYingzhao 2007Chinese Journal of Aeronautics2007,20,4:5
2Atomic-scale mechanism of the θ’’→θ’ phase transformation in Al-Cu alloys显示文摘The phase transformation of θ’’→θ’ in an Al-5.7 Cu alloy was investigated by aberration-corrected scanning transmission electron microscopy, and the tranformation mode of θ’’→θ’ during aging treatment was clarified. In the presence of the θ’ phases, θ’ was found to be formed by in-situ transformation fromθ’’ with the same plate shape, size and broad faces. The transformation starts from multiple sites within the θ’ precipitate and the whole θ’ phase finally forms as the preferential θ’ sections grow and connect with each other. Antiphase domain boundaries are also found in some θ’ precipitates when the disregistry exists between different θ’ sections.Zhenju Shen Qingqing Ding Chunhui Liu Jiangwei Wang He Tian Jixue Li Ze Zhang 2017Journal of Materials Science & Technology2017,33,10:3

5Asymptotic Normality of LS Estimate in Simple Linear EV Regression Model显示文摘尽管 EV 模型是,理论上,更多为测量错误在存在的应用拨出,人们仍然是使倾向使用平常的回归模型的更多;由于统计推理的困难的传统的 LS 方法;计算。在 EV 模型学习 LS 估计的表演因此是有意义的。在这篇文章,我们获得在线性 EV 模型保证回归系数的估计的 asymptotic 规度的一般条件。结果与在平常的回归模型的相应结果在某些方面不同,是显著的。Jixue LIU 2006Chinese Annals of Mathematics,Series B2006,27,6:1
6Boosting High-Voltage and Ultralong-Cycling Performance of Single-Crystal LiNi_(0.5)Co_(0.2)Mn_(0.3)O_(2) Cathode Materials via Three-in-One Modification显示文摘LiNi_(0.5)Co_(0.2)Mn_(0.3)O_(2) is extensively researched as one of the most widely used commercially materials for Li-ion batteries at present.However,the poor high-voltage performance(≥4.3 V)with low reversible capacity limits its replacement for LiCoO_(2) in high-end digital field.Herein,three-in-one modification,Na-doping and Al_(2)O_(3)@Li_(3)BO_(3) dual-coating simultaneously,is explored for single-crystalline LiNi_(0.5)Co_(0.2)Mn_(0.3)O_(2)(N-NCM@AB),which exhibits excellent high-voltage performance.N-NCM@AB displays a discharge-specific capacity of 201.8 mAh g^(−1) at 0.2 C with a high upper voltage of 4.6 V and maintains 158.9 mAh g^(−1) discharge capacity at 1 C over 200 cycles with the corresponding capacity retention of 87.8%.Remarkably,the N-NCM@AB||graphite pouch-type full cell retains 81.2% of its initial capacity with high working voltage of 4.4 V over 1600 cycles.More importantly,the fundamental understandings of three-in-one modification on surface morphology,crystal structure,and phase transformation of N-NCM@AB are clearly revealed.The Na+doped into the Li–O slab can enhance the bond energy,stabilize the crystal structure,and facilitate Li+transport.Additionally,the interior surface layer of Li^(+)-ions conductor Li_(3)BO_(3) relieves the charge transfer resistance with surface coating,whereas the outer surface Al_(2)O_(3) coating layer is beneficial for reducing the active materials loss and alleviating the electrode/electrolyte parasite reaction.This three-in-one strategy provides a reference for the further research on the performance attenuation mechanism of NCM,paving a new avenue to boost the high-voltage performance of NCM cathode in Li-ion batteries.Bao Zhang Jixue Shen Qi Wang Changqing Hu Bi Luo Yun Liu Zhiming Xiao Xing Ou 2023Energy & Environmental Materials2023,6,1:1

12Existence of unbiased estimate of regression parameters in simple linear EV models显示文摘It is well known that for one-dimensional normal EV regression model X = x +u, Y= α+βx+e, where x, u, e are mutually independent normal variables and Eu = Ee= 0,the regression parameters α andβ are not identifiable without some restriction imposed on the parameters. This paper discusses the problem of existence of unbiased estimate for α and β under some restrictions commonly used in practice. It is proved that the unbiased estimate does not exist under many such restrictions. We also point out one important case in which the unbiased estimates of α andβ exist, and the form of the MVUE of α and β are also given.LIU Jixue & CHEN Xiru Department of Statistics and Finance, University of Science and Technology of China, Hefei 230026, China Department of Mathematics, Graduate School of Chinese Academy of Sciences, Beijing 100049, China 2005Science China Mathematics2005,48,7:1

19Linear EV model with replicate observations on independent variables显示文摘This paper studies the linear EV model when replicate observations are made only on independent variables. We construct the estimates of regression coefficients and prove the consistency and asymptotic normality under some proper conditions. Results obtained reveal the difference between the case where the independent and dependent variables are observed repeatedly and simultaneously and the case studied in this article.LIU Jixue, ZHANG Sanguo & CHEN Xiru Department of Statistics and Finance, University of Science and Technology of China, Hefei 230026, China Department of Mathematics, Graduate School of Chinese Academy of Sciences, Beijing 100049, China 2006Science China Mathematics2006,49,6:1
