摘要
对血液的交流电特性做了较全面的研究。针对血液这一特殊对象，在测试方法及测量系统设计中做了较深入的工作。在１ Ｈｚ～１０ ＭＨｚ 频率范围内测定了正常成人全血的电频谱特性。实验发现，正常成人血液电导随测量信号频率增加在１００ Ｈｚ～１０ ｋＨｚ范围内有显著的增加，但相位基本不变。考虑到血液的这一电特性，将对以前电导法测红血球压积、血液粘度等工作做一定的补充和修正。
The blood electro frequency properties of normal human body were investigated in the range of 1Hz 10MHz. The method of testing and the equipment were examined to meet the need for the measurment of blood property. In the experiment, it was discovered that the electric conductivity of blood increased obviously with the increase of testing frequency in the rage of 100Hz 10KHz, but almost no change in phase was noted. This result suggests it is necessary to modify the previous work and build up a reasonable equivalent electric model of blood.
