本文由半经典理论推得了原子电离率随脉冲空间传输出现周期性起伏这一新的相干作用结果,这点与速率方程的预计相差甚远.文中定量说明了利用速率方程对同位素分离过程进行分析时产生的系统误差,为实验分析工作提供了依据.     

DYNAMIC PROPERTIES OF ASSISTANT SOUNDER IN BLACK CICADA (C.atrata FABRICIUS)

The dynamic properties of the assistant sounders in the black cicada are given and the twitching properties of Contraction in the sounding muscle are revealed in this paper.For the operculum, tymbal cover and joint membrane, each of their vibration periods consists of three subgroup vibrations (SGV_(a,b,c)) corresponding to amplitude-modulation pulse trains (AMPT_(1,2,3)) in every syllable of synchro song. In comparison with the vibration at dorsum, the SGV_(a-c) have a subband with the function of regulating the tone. During calling song continuously, the pressure change inside the resonant cavity and the airspeed through the spiracles on both sides are about 7. 94—15.88 Paand 0.59—0.84 cm~3/s respectively, and they increase by about 7 and 2.6 times as the abdomen is moved. When the contraction motion of the sounding muscle comes up to the critical Sounding state, it further produces the twitching process, and drives the sounding membrane and the toning plate-membrane to produce AMPT_(1-3) and SGV_(a     

光信息综合实验中光源的选择和性能改善

在光信息综合实验中,在分析氦氖激光器的优缺点的基础上,阐述了半导体激光器的显著优点以及存在的一些局限性。利用实验室现有的器件,引导学生对半导体激光器进行了光束准直和整形以提高激光器的性能,并用已优化的半导体激光器作为光源进行了全息光栅和全息透镜的制备以及电光调制和液晶光阀等实验。结果表明,性能改善的半导体激光器完全可以取代氦氖激光器,可满足光信息综合实验的要求。在整个设计制作过程中,培养了学生分析问题和解决问题的能力。

结合最新病毒传播的研究工作,建立了一系列微观病毒传播系统,并对动态系统作了简单的分析,是对宏观疾病传播的内在规律的描述和研究,有利于疾病发展趋势的预测和最优化控制策略的研究.     

Biosensors with reversed micelle-enzyme sensitive membrane

The effect of reversed micelle on the conformation of enzyme was studied by sensor techniques. By means of measurement of the response current of GOD enzyme membrane electrode, the effects of enzyme embedded in AOT reversed micellar on GOD conformation and catalytic activity are discussed. The results show that the response current increased greatly with decreasing ratio of GOD/AOT, meaning that the catalytic activity and the conformation stability of enzyme were enhanced.
