Propagation Properties of Electromagnetic Wave in a Plasma Slab

In this paper, the calculated results about the propagation properties of electromag-netic wave in a plasma slab are described. The relationship of the propagation properties with frequencies of electromagnetic wave, and parameters of plasma (electron temperature, electron density, dimensionless collision frequency and the size of the plasma slab) is analyzed.     

Numerical Investigation on the Flow and Temperature Fields in an Inductively Coupled Plasma Reactor

1. IntroductionWith a rapid development of space technology,a variety of heat--resistant material have been developed since 60's to protect the spacecraft fromthe overheating when re-entry to the atmosphere.Modern materials qualified for thermal-resistance requires an ability to duplicate and understand theprevailing complex physico-chemical phenomena including thermal and chemical phenomena near thesurfaCe of the material. Usually the DC plasma gen--'erators serve to simulate the thermal and…     

大气飘尘采样器的流量控制系统

一、引言本文讨论用于大气飘尘采样器的流量控制系统。大气飘尘采样器是研究颗粒型大气污染的主要仪器之一。评价采样器性能的一个重要指标是气体流量的稳定度。根据国家城乡建设环境保护部的规定,大、中流量采样器的流量波动范围不得超过±5％。因此,在设计采样器时,流量控制系统是要碰到的一个主要问题。采样器常常在无人照顾的情况下在室外长

一种喷涂机用半流体防护脂的研制

2011年，成都蜀光石油化学有限公司（下称蜀光公司）接到2家用户的合作要求，希望为其提供一种可在野外露天、海上运输等特殊场合使用的长效防护油脂。研制产品必须具有良好的防护性，且防护期越长越好，可满足手工涂刷和小型半自动化喷涂设备的使用需要，但同时要求控制产品成本。     

Characteristics of Plasma Spraying Torch with a Hollow Cathode

1. IntroductionPlasma spraying has became a welLestablishedand widely-used technology with various industrialapplications[1,2,3]. In traditional plasma sprating,the design of plasma torch has been essentially thesame, based on producing a plasma jet by a dc arcopersted between a stick-type cathode and a nozzleshaped anode[4,5]. The powder is injected radiallyillto the plasma flame either within the anode channel or a short distance from the anode. With radialinjection of powders the heating a…     

Characteristics of Gliding Arc Discharge Plasma

A gliding arc discharge plasma and its characteristics are described. Analysis of the production principle of the plasma is presented. Some experimental results about two novel types of the gliding arc plasma generator have been obtained. These types of gliding arc plasma axe potentially usable in the chemical industry and environmental engineering.
