The dynamic stability of the shell under axial compression is analyzed qualitatively by the linear equation of motion. There are three kinds of equilibrium state with different value dynamic parameter. They are stable,neutral and unstable equilibrium respectively.

利用线性的运动方程对轴压圆柱壳稳定性进行了定性分析，依动力学参数取值范围的不同，方程的解有稳定平衡、中性平衡和不稳定平衡三种情况，并给出了动力学参数与载荷参数之间的依赖关系。

They are stable,neutral and unstable equilibrium respectively. Next for a simply supported shell the relation between dynamic parameter and load parameter is given. damping and external forcing are introduced into the nonlinear equation of motion.

This paper deals with the partial capacitance calculation of the high voltage transmission line for the neutral beam injectors.

该文研究了中性束注入系统中高压传输线部分电容的求解问题；根据传输线多层同轴导电壳的结构特点，利用多重镜像法确定与平行导线相应的一系列的镜像线电荷，求解的问题变为由一系列平行线电荷构成的电场问题，传输线的部分电容则通过各导体间的电位系数来求得；这一方法避免了直接求解的困难以及大量数值计算等问题。

The single mechanical seals of five PHP pumps, nine PLA pumps, two THD pumps and nine ZA pumps in the acetic acid plant were changed into dual mechanical seals based on not changing main parts such as casing, impeller, shaft, bearings house etc. to solve the leakage problems of flammable, explosive, poisonous, harmful substances, such as acetic acid, methyl iodide, hydroiodic acid, and propionic acid etc.

通过对醋酸装置中所选用的5台PHP型、9台PLA型、2台THD型及9台ZA型单级卧式脚支撑化工离心泵，在不改变泵壳、叶轮、轴、轴承箱等主要部件的基础上，将原来的单端面机械密封改造为双端面机械密封或串联式机械密封，以此来防止所输送的易燃、易爆、有毒、有害高危介质（如醋酸、碘甲烷、碘化氢、丙酸等）外漏。
