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.

如果我们正确使用静电探针，静电探针有望用于探索碳氢化合物火焰特征的诊断。然而，只有有限数量的研究人员了解这些诊断的细节并成功使用它们。为了增加更多能够正确使用静电探针的燃烧科学家，笔者在前人对静电探针特性研究的基础上，尝试介绍静电探针的基本特性和正确使用方法。介绍了静电探针和电路的示例。已尝试解决 1) 直流放大器和模数转换器之间的噪声以及最佳信号和接地，2) 优化鼻过滤器，3) 开发能够在以下情况下使用的探针高温空气燃烧。我们提出了原型测量系统。基于该原型，静电探针的测量系统将推向市场。
