Clarification of Problems in Electrostatic Probe Measurement and its Application

如果使用得当，静电探针有望用于探测碳氢化合物火焰的特征。然而，只有少数研究人员知道这些诊断方法的细节，并成功地使用了这些方法。为了使更多的燃烧科学家能够恰当地使用静电探头，我在前人对静电探头特性研究的基础上，尝试介绍静电探头的基本特性和正确使用方法。给出了静电探头和电路的实例。本文尝试解决1)直流放大器和A - D转换器之间的噪声，优化信号和地，2)优化鼻型滤波器，3)开发可用于高温空气燃烧的探头。我们提出了原型测量系统。在样机的基础上，静电探针测量系统即将推向市场。

Electrostatic probes are promised diagnostics for exploring characteristics of hydrocarbon flames if we use those appropriately. However, only a limited number of researchers have known the details of those as diagnostics and used those successfully. For increasing the number of combustion scientists who can use electrostatic probe appropriately, I have attempted to introduce into basic characteristics and correct use of electrostatic probes on basis of previous studies on the characteristics of electrostatic probes. Examples of electrostatic probes and electric circuit are presented.Attempts have been made to solve 1) noise between DC Amplifier and A to D Converter and optimum signal and ground, 2) optimizing the Nose filter, 3) development of the probe enable to use at the High Temperature Air combustion. We propose the proto type measuring system. Based on the proto type, measurement system of the electrostatic probe will be coming to the market.
