本文以二年生盆栽苹果(辽伏)为材科研究了叶水势与相对含水量的关系及其日变化动态;叶水分状况与蒸騰强度及光合强度的关系。研究结果表明: 叶水势最低值(-26.4巴)出现在10时,叶水势最高值(-22.7巴)出现在第二天的6时。不同部位叶水势不同。同一枝条不同节位叶水势为:下位叶<中位叶<上化叶。同一树冠外围叶水势为:下部叶>中部叶>上部叶。树冠内膛和外围叶水势为:内膛叶水势>外围叶水势。黎明时、日出时叶水分状况与白天的蒸騰强度的关系达到极显著的水平。日出后(10时)叶水分状况与蒸騰强度的关系有前者那样显著,但都表现出一定的阈值效应

Nonthermal effect of eletromagnitic radiation on biology is studied by using nonequilibrium statistics. On the bases of Wu and Austin's and I. TURCU'S work, trilinear hamiltonian is used as a simplified model of the Frohlich type. So, it is discussed and tested that certain frequ- ency electromagnetic wave at lower power produces several effect (freq- uency selectivity, threshold effect and coherent excitation). The concl- usion is in conformity with the experimental evidence.

本文用非平衡统计的方法,对生物系统在外界电磁波作用下的非热效应机制进行探讨。在Wu和Austin及I.TURCU等人工作的基础上,用三变量哈密顿作为Frohlich类型激励的简化模型。在此假设下,讨论并证实了特定频率的低功率电磁波使生物体产生的几种效应(频率选择效应、阈值效应及单一模式的相干激励)。这与实验结果定性相符。

In this paper, the experimental results of Alfven wave excitation in KT-5B Tokamak are presented. The results show that there is a quite broad excitation region for shear Alfven waves, the wave energy coupling indicated by the antenna loadings increase as the plasma current and toroidal magnetic field increase. The electron temperature threshold effects and the preliminary evidence of the surface electrostatic wave are observed.
