本文讨论了用直流朗缪尔探针原位测量电离层/等离子体中电子温度的方法。已经报道的主要仪器是常规的DC朗缪尔探针，其探针电压被扫描;脉冲探针，其使用脉冲偏置电压;整流探针，其使用正弦信号;以及谐振锥形探针，其使用无线电波传播。内容回顾了过去使用上述工具所作的观察。我们还讨论了可靠测量应考虑的技术因素，如与电极和卫星表面污染有关的问题。最后，我们讨论了在不久的将来要研究的研究课题。
Herein, we discuss the in situ measurement of the electron temperature in the ionosphere/plasmasphere by means of DC Langmuir probes. Major instruments which have been reported are a conventional DC Langmuir probe, whose probe voltage is swept; a pulsed probe, which uses pulsed bias voltage; a rectification probe, which uses sinusoidal signal; and a resonance cone probe, which uses radio wave propagation. The content reviews past observations made with the instruments above. We also discuss technical factors that should be taken into account for reliable measurement, such as problems related to the contamination of electrodes and the satellite surface. Finally, we discuss research topics to be studied in the near future.
