摘要: Penning捕获器[1]是微等离子体实验中的一个装置。为了使用结构分析程序计算它的静电场,本文提出一种"退化模拟方法"。用这种方法计算的结果与实验结果吻合。结构分析程序已被广泛应用于工程和科研领域,用本文的方法,可把它推广用于解决非结构力学的场问题。

Abstract: Penning trap is an advanced equipment of microplasmas. To find its electrostatic field,a general "degenerated analogy method" is presented. As an application of this method, the electrostatic field is simply solved by structural analysis programs. The numerical result is consistent with the experimental result. The structural analysis programs are widely implemented by engineers and researchers. The users can simply extend their function to solve the engineering field problems not belonging to structural mechanics.

Key words: penning trap, degenerated analogy method, structural analysis program
