摘要
本文从氩等离子体的简化状态方程出发,结合气体动力学和热力学等基本方程,直接推导出适用于各种氩等离子体发生装置(如等离子体手术刀,微束等离子体焊接和等离子体热化学等)的解析表述式。这些表达式的主要特点是:各物理量密切联系装置的几何尺寸,工程计算和设计简便,各物理量适应宽广工程应用范围,并能给出相当精确的计算结果。
Based on the simplified state equation of Argon plasma and the basic equations of gas dynamics and thermodynamics,the authors have deduced directly the analytical expressions which can be applied to various kinds of Argon plasma generators (i.e.the plasma scalpel,mini-plasma arc welding and plasma thermochemistry).The features of these expression are as follows :each physical parameter is closely connected with geometrical dimensions; the engineering computation and design is relatively simple;each paysical parameter is suitable in a wide range of engineering applications;and furthe- rmore,considerably precise computational results are given.
