摘　　要：空间电场是研究空间物理、空间天气学和空间环境的重要参量。论述了电离层空间准直流电场和交流电场的本质来源、表现形式及其频率和幅值等特性;指出了双探针式空间电场探测技术是目前主要采用的方法,而电子漂移式可作为对双探针式的验证与补充;在此基础上,阐述了双探针式和电子漂移式空间电场探测原理、数理模型以及物理本质。Space electric field is an important parameter in the study of space physics,space weather and space environment.In this paper,the essential origin and manifestation of space quasi DC and AC electric field in the ionosphere are discussed,and its characteristics of frequency,amplitude and so on are also narrated. Then,it is pointed out that the double probe type of space electric field detection technology is the main method at the present,and the electronic drift type can be used as the verification and the complement of the double probe type. Based on the above,the operational principle,mathematical model,and physical essence of double probe and electronic drift space electric field detection technology are described respectively.
