摘要
深层介质带电是引起卫星运行异常的重要原因。作为卫星内带电分析研究的最有效手段之一,自20世纪70年代,空间电荷测量技术得到不断发展和完善,测量分辨率达1μm量级。电荷分布曲线得到的信息对介质中带电现象的理解得到了极大提高。介绍了空间电荷测量技术在卫星内带电分析中的应用及其发展趋势。
Internal dielectric charging is one of the most important reasons for the anomalies of satellites. As an efficient method for internal dielectric charging analysis, the measurement techniques of space charge distribution within dielectric materials have been developed since 1970s, and the resolutions down to 1 μm. The understanding of charging phenomena in dielectrics has been significantly improved from information gained by charge-profile measurement.The applications in internal dielectric charging and tendencies are described.
