The study was supported by National Nature Science Foundation of China of ""Biological foundation study of electrical indexes assessing tree vigor"". The mechanism of tree's leaf and stem capacitance and the application of electrical indexes under environmental stresses were studied. The main conclusions are summarized as following:(1) The leaf capacitance had significant positive correlations with leaf exosmosis electro conductivity, exosmosis percentage and leaf absolute moisture content, had significant negative correlations with leaf electrolyte electro conductivity and had no correlations with leaf relative water content.

本研究在国家自然科学基金"林木健康状况评价的电指标生物学基础"的支持下，对树体叶片电容和树体干部电容的机理及外界胁迫因素作用对树体电指标的影响进行了初步研究，研究的主要结论包括：(1)树木叶片电容与单位质量叶片离子外渗液电导率、叶片细胞离子外渗百分率及叶片绝对含水率呈显著的正相关关系，与单位质量叶片总电导率呈显著的负相关关系，与叶片相对含水率的相关性不显著。

Within the amended algorithm, semi-optimistic locking mechanism in CIAO is replaced by token mechanism, and Receiver-reliable multicast based on the father node number is proposed to enhance robustness of system. Entities and avatars in scene are organized the structure of tree. Its father node number is augmented in each entity's ESPDU (Entity State Protocol Data Units). The receiver adjusts the structure of local scene tree according to the node number of package received.
