【摘要】：人体的电流效应是个跨物理、生物、医学的边缘学科，，目前还没有专门的完整的专著对此进行研究和论述。本文从物理学、生物学、医学的角度，详细分析了人体在低频电流(频率为0—1000Hz，主要是直流电流和低频交流电流)作用下的导电机理，特别是对组成人体阻抗的皮肤阻抗和人体内部阻抗的形成和影响因素进行了比较详细的分析，提出并建立了直流电流和低频交流电流通过人体时的人体阻抗电路模型。论文详细分析了在直流电流和低频交流电流作用下的人体电流效应，寻找出两种不同电流流过人体时的电流大小与其所产生的效应之间的规律，做出两种电流的人体效应曲线，总结出人体流过直流电流和低频交流电流时的人体效应的规律。此外，本文基于低频电流的人体阻抗电路模型和人体的电流效应，进一步分析了直流电和低频交流电在用电安全方面的应用，为人身安全用电提出了一些有价值的参考意见。最后，论文分析了人体的电流效应在医学检查、医学治疗等方面的应用，展望直流电流、低频交流电流在医学上的应用前景。
[Abstract]:The current effect of human body is an interdisciplinary subject of physics, biology and medicine, which has not been studied and discussed in a special monographs. In this paper, from the point of view of physics, biology and medicine, the conduction mechanism of human body under the action of low frequency current (frequency 0-1000 Hz, mainly DC current and low frequency AC current) is analyzed in detail. In particular, the formation and influence factors of skin impedance and internal impedance of human body are analyzed in detail, and the impedance circuit model of human body when DC current and low frequency AC current pass through human body is proposed and established. In this paper, the human body current effect under the action of DC current and low frequency AC current is analyzed in detail, and the laws between the current magnitude and the effect produced by the two kinds of currents passing through the human body are found out, and the human body effect curves of the two kinds of currents are made. The rules of the human body effect when the human body flows through the DC current and the low frequency AC current are summarized. In addition, based on the human impedance circuit model of low frequency current and the current effect of human body, the application of direct current and low frequency alternating current in power safety is further analyzed in this paper, and some valuable suggestions for personal safety are put forward. Finally, the paper analyzes the application of human body current effect in medical examination and medical treatment, and looks forward to the application prospect of DC current and low frequency AC current in medicine.
