植物细胞膜的超声波振动:树木中的水提升,电现象

Ultrasound vibrations of plant cells membranes: water lift in trees, electrical phenomena

Mark E. Perel'man, Galina M. Rubinstein

摘要:

离子流改变植物细胞膜上的电荷密度(电位),导致压缩细胞膜的库仑力和抵消胡克弹性力的不平衡。随着超声波和电磁辐射的产生,将导致膜的振动,直到建立新的平衡。这种振动导致声流,其功率足以使树木中的水上升,其脱气,植物中的cycloses和一些电现象等。这种现象解释了已知的树木中的超声噪声和韧皮部流中颗粒的重新分布的观察结果。已知的监督和植物解剖学的考虑导致在xilem和3倍更大的韧皮部中的声流的频率的估计的顺序为150-200 kHz。所提供的机制的检查可以通过调查植物的声辐射和电磁辐射来进行。关键词:工厂,超声波,声流,液压PACS:43. 25.

英文摘要:

Alterations of charges density on membranes (potentials) of plant cells by ion currents lead to disbalance of Coulomb forces compressing membranes and counteracting Hookean elastic forces. It should results in membrane vibrations till establishment new equilibrium with generation of ultrasound and electromagnetic radiations. Such vibrations lead to acoustical flows, power of which is sufficient for water lift in trees, its degassing, for cycloses and some electric phenomena in plants and so on. This phenomenon explains the known observations of ultrasound noises in trees and redistribution of particles in the phloem flow. Known supervisions and consideration of anatomy of plants result in estimations of frequencies of the order of 150-200 kHz for acoustical flows in xilem and three times bigger in phloem. The checking of offered mechanism can be carrying out via investigation of acoustic and electromagnetic radiation of plants.
