THERMODYNAMIC PROPERTIES OF ALPHA-HELIX PROTEIN - A SOLITON APPROACH - COMMENT

Physical Review E

We disagree with the deduction of the equations of motion for the Davydov soliton and of the results in the paper by Jia-Xin Xiao et al. [Phys. Rev. A 44, 8375 (1991)]. The weakness and faults of the Davydov theory are also indicated.

Ion sputter erosion in metallic glass-A response to "Comment on: Homogeneity of Zr(64.13)Cu(15.75)Ni(10.12)Al(10) bulk metallic glass" by L-Y. Chen, Y-W. Zeng, Q-P. Cao, B-J. Park, Y-M. Chen, K. Hono, U. Vainio, Z-L. Zhang, U. Kaiser, X-D. Wang, and J-Z Jiang J. Mater. Res. 24, 3116 (2009)

Journal of Materials Research

The morphology of the dark and bright regions observed by transmission electron microscopy for the Zr(64.13)Cu(15.75)Ni(10.12)Al(10) bulk metallic glass strongly depends on the ion beam parameters used for ion milling. This indicates that the ion beam could introduce surface fluctuation to metallic glasses during ion milling.

Improved Nonlinear Equation Method for Numerical Prediction of Jominy EndQuench Curves

钢铁研究学报(英文版)

Without considering the effects of alloying interaction on the Jominy endquench curves, the prediction results obtained by YU Baihai′s nonlinear equation method for multialloying steels were different from those experimental ones reported in literature. Some alloying elements have marked influence on Jominy endquench curves of steels. An improved mathematical model for simulating the Jominy endquench curves is proposed by introducing a parameter named alloying interactions equivalent (Le). With the improved model, the Jominy endquench curves of steels so obtained agree very well with the experimental ones.

三维晶粒长大速率方程的大尺度Potts模型Monte Carlo仿真验证

王浩 , 刘国权 , 秦湘阁

金属学报

采用Potts模型Monte Carlo方法对3种现存的三维个体晶粒长大速率拓扑依赖性 方程进行了仿真验证. 结果表明, Rivier速率方程认为晶粒 体积变化率dVf/dt与晶粒面数f成线性关系, 与仿真 结果明显不符, 不适用于描述三维晶粒长大过程的动力 学. 当晶粒面数f≥8时, Yu-Liu速率方程和 MacPherson-Srolovitz速率方程均与仿真结果很好吻合, 表明这两者均可以用来定量描述三维晶粒长大过程的动力学；当 f＜8时, 这两个方程均与仿真结果有显著差异.

膜片开关用银浆制备使用的有机体系中，树脂、溶剂和添加剂对产品的性能和有害元素控制有重要的意义。经对比实悚，以热塑性聚酯为主体树脂，以MEA混合溶剂为溶剂，以YU-201、硅烷偶联剂以及自制增强塑性材料M-17材料为混合添加剂，制成有机载体。使用该载体制备出的浆料符合膜片开关银浆性能要求，且满足欧盟RoHS指标卤素控制要求。
