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.

本文实验研究了ZuO压敏陶瓷击穿、非线性指数α和脉冲大电流冲击后击穿场强E_1mA变化率的几何效应．对ZuO晶粒尺寸的统计分析表明它基本服从正态分布．建立了微观结构模型，计算机模拟得到的击穿几何效应规律与实验规律相同．临界厚度d_c与方差σ²和平均晶粒尺寸μ的乘积成正比．
