随机矩阵理论最初是由维格纳在五十年代为处理复杂量子多体的本征值和本征函数的统计性质而提出来的。在过去的二十年里,该理论经历了出乎意料的迅速发展。它正在被成功地应用于越来越多的物理问题,并成为探讨多体问题的一个重要工具。...

随机矩阵理论最初是由维格纳在五十年代为处理复杂量子多体的本征值和本征函数的统计性质而提出来的。在过去的二十年里,该理论经历了出乎意料的迅速发展。它正在被成功地应用于越来越多的物理问题,并成为探讨多体问题的一个重要工具。本文将首先简述随机矩阵理论的发展及动态,然后介绍该理论在原子核激发与衰变过程中的应用以及在一个生命演化模型（爱根模型）中的应用。

We studied the impact of the thickness of GaN buffer layer on the properties of distributed Bragg reflector (DBR) grown by metalorganic chemical vapor deposition (MOCVD). The samples were characterized by using metallographic microscope, transmission electron microscope (TEM), atomic force microscopy (AFM), X-ray diffractometer (XRD) and spectrophotometer. The results show that the thickness of the GaN buffer layer can significantly affect the properties of the DBR structure and there is an optimal thickness of the GaN buffer layer. This work would be helpful for the growth of high quality DBR structures.

Introduction Molybdenum is an important component of structural material for fission and future fusion reactors. It consists of seven isotopes. Therefore, fast neutrons can lead to many nuclear reactions. One of them is92Mo（n,p）92mNb reaction. Several authors published their data for this reaction, while most of the cross section determinations were
