人红细胞在两种典型非均匀电场中的电介基平动

电中性介质微粒在非均匀电场中将产生规律性运动,即电介基平动。本文报道了作者关于人红细胞在蔗糖溶液中电介基平动的实验结果,研究了人红细胞在两种典型的非均匀电场中,即针—板电场和恒动力电场中的电介基平动,并对这两种电场进行了分析,论讨了生物微粒电介基平动的理论意义及实际应用价值。

In a nonuniform field the particales of neutral matter tend to move trans la- tionally and regularly.The motion is dielectrophoresis.This paper reports the ex- periment result of human erythrocyte dielectrophoresis in the sucrose solution.The translational motion is caused by two typical kinds of nonuniform field seperately, which are pin-plate field and constant force(along some direction)field.The pa- per analyses the theoritic significance and the applycational value of biological pa- rticale dielectrophoresis.
