The soil urease and invertase activity effected by Hg was investigated in different fertility soils. The results show that soil urease activity、maximum reaction velocity (Vmax、Vmax/Km) and reaction velocity constant k have remarkably negative correlation with Hg concentration so that these can be used as ecological indexes of soil polluted by Hg, Km changes a little indicating that the reaction mechanism of Hg and urease is nonreversible competitive restraint. Urease of low soil fertility is more damaged by Hg than that of high soil fertility, with severe pollution at Hg concentration of 6.00 and 14.79mg/kg respectively; while invertase is less sensitive to Hg than urease. Cultural time has less influence on the relationship of soil enzyme and Hg concentration.

对不同肥力土壤脲酶和转化酶活性受汞影响进行了研究，结果显示，土壤脲酶活性、最大反应速度Vmax 、Vmax/Km和反应速度常数k与汞浓度呈现显著或极显著负相关关系，表明其可作为土壤汞污染的生态指标；米氏常数Km则变化较小，表明汞与脲酶作用机理为不可逆竞争抑制；低肥力土壤脲酶比高肥力土壤脲酶受汞毒害作用更强，当汞浓度分别为6.00和14.79mg/kg时即达到严重污染；而转化酶对汞的敏感性较差；培养时间对土壤酶与汞浓度间关系影响较小。

Through analysing, we found that the average P/E ratio of industry, ROE, expenses rate are the factors influencing function to be relatively remarkable to company P/E ratio; The relations between company P/E ratio and such indexes as ROE, etc are all negative relevant, it is opposite to analyse with the theory, this kind of conclusion that completely contradicts proves the development of the stock market of our country is still at very unripe stage, the phenomenon that the high-quality stock is underestimated is serious, the whole market has even turned around; P/E ratio and net assets factor are in close relations, this includes the price of evaluation on net assets, rentability of the net assets, etc.

其次是对公司市盈率影响因素的分析，本文考虑了21个可能的影响因素，通过分析发现行业平均市盈率、净资产收益率、费用率等因素是对公司市盈率影响作用相对显著的因素；净资产收益率等指标与公司市盈率都是负的相关关系，与理论分析相反，这种截然相反的结论说明我国股市的发展还处于很不成熟的阶段，优质股票被低估的现象严重，整个市场甚至倒了过来；市盈率与净资产因子的关系密切，这包括了净资产的收益性、净资产的成长性以及股市上对净资产的评估价格等。

On the basis of state space model of system dynamics, the decomposition of periodic term and trend term in the time series of both power demand and Gross Domestic Product are carried out respectively, and it is discovered that there is a strong correlativity between the periodic term...

文章基于系统动力学的状态空间模型对电力需求与国内生产总值(GrossDomesticProduct，GDP)增长率时间序列分别进行周期项与趋势项的分解，发现电力需求与GDP分解的周期项之间存在很强的相关关系；基于此关系及电力需求增长率序列数据自身的变化规律，采用计量经济模型预测了2004~2008年我国电力需求增长率，以期为当前的电力规划工作提供参考数据。
