摘要
根据探针收集电子流的理论，提出电子流对探针电位的一次微商的最大值对应着等 离子体电位。以一台微型计算机作为静电探针系统的核心，统一完成探针系统的控制、记 录和计算工作。在两分钟之内可完成等离子体电位、悬浮电位、电子能量分布和电子密 度的测量。
Based on the theory of electron current collected by probe, that the maximum derivative of electron current with respect to probe potential corresponds with the plasma potential is presented. A electrical probe system is set up, in which the most important part is a microcomputer. Overall control, record and calculation are carried out only by the microcomputer. Getting the plasma potential, floating potential, energy distribution and density of electron takes no more than two minutes.
