关于分布函数极大值位置的讨论

将关于某个变量的连续分布函数进行变数变换，除非新老变数为线性关系，否则变换前后的分布函数的极大值之间的关系一般会不同于新老变数之间的关系。     

Low-amplitude Screening-photovoltaic Spatial Solitons in Biased Photovoltaic Photorefractive Crystals

The low-amplitude spatial solitons in biased photovoltaic photorefractive crystals are investigated theoretically. The analytical solutions for both the bright and the dark low-amplitude screening-photovoltaic spatial solitons in photorefractive crystals are obtained. The expressions for the width of these solitons are given. The explicit expressions for the spatial deflection and angular deviation of the bright low-amplitude screening-photovoltaic spatial soliton are also presented by taking into account the effect of diffusion.

基于多维名义模型的加权似然估计方法(英文)

The Monte Carlo study evaluates the relative accuracy of Warm's (1989) weighted likelihood estimate (WLE) compared to the maximum likelihood estimate (MLE) using the nominal response model. And the results indicate that WLE was more accurate than MLE.     

强平稳ρ-混合序列的精确渐近性

研究了强平稳ρ-混合序列部分和Sn=X1 X2 … Xn的精确渐近性:即当ε↘0时,概率级数∞∑n=1ψ(n)P(|Sn|≥εH(n))的极限行为和收敛速度,并揭示了函数ψ(n)与H(n)之间的关系.     

Theoretical Studies on the N-Phenylpyrrolidine Formation Mechanism Based on the Reaction of Phenylamine with 1,4-Butanediol

The reaction mechanism of phenylamine reacting with 1,4-butanediol to give N- phenylpyrrolidine was investigated with traditional transition state theory. Based on the experimental results, two reaction channels were discussed. The geometries of their reactants, products, intermediates and transition states were optimized. The possible transition State and activation energy were determined by vibrational analysis and IRC verification. And finally, the main reaction channel was given.
