通过热力学计算证明,超声在生物组织中的粘滞耗散和热耗散引起的吸收低于化学弛豫引起的非经典吸收,低频低强度的超声吸收在生物组织中的熵产生对于癌细胞和正常细胞是不同的,这种不同联系于二者的酸度差异.理论计算证明,低频低强度的超声照射可以导致癌细胞和正常细胞熵产生率的倒转,从而可以改变熵流方向,抑止癌的毒性信息流的扩散.这提供了癌症理疗的一个新方案.
The results of thermodynamic calculation show that the ultrasonic absorption caused by viscous dissipation and heat dissipation in biological tissues is lower than the non-classical absorption caused by chemical relaxation. The entropic generation of low-frequency and low-intensity ultrasonic absorption in biological tissues is not suitable for cancer cells and Normal cells are different and this difference is related to the difference in acidity between the two.The theoretical calculations show that low frequency low intensity ultrasound irradiation can lead to reversal of entropy generation rate of cancer cells and normal cells and thus can change the direction of entropy flow and inhibit the The proliferation of toxic information flows.This provides a new approach to cancer physiotherapy.
