电场引发液晶生物膜弹性形变的场强阈值

The electric field intensity threshold of causing liquid crystal biological membrane elastic twist

电场对动植物的生长发育均有一定的影响 ,被称为电场生物效应。作者从生物膜的液晶模型出发 ,利用液晶连续体弹性形变理论推导出场强阈值 ,从理论上给出了电场对液晶生物膜影响的物理机制 ,并以此讨论了电场对生物影响的阈值效应等问题。

The animals and plants growth and development can be affected by electric field, this phenomenon is called electric field biological effect. Up to now, the mechanism of biological effect by electric field is not clear. In this paper, using the liquid crystal biological membrane model and its consecutive elastic theory, we have got a electric field intensity threshold, and have given the physical mechanism of liquid crystal biological membrane affected by electric field in the theory. Finally, the characteristic of electric biological effects is explained.
