Based on natural gas state equation and dynamic theory of natural gas migration, natural gas velocity of flow rate equation before and after temperature and pressure decreasing is fetched, and with which interface natural gas lengths in different reservoirs are calculated and the changing law of equivalent-length natural gas in migration is analyzed, whence it is discovered that migrating velocity of natural gas along tilting up reservoir is increasing inch by inch, along with temperature and pressure continuously decreasing.

由此发现，在运载层物性不变的情况下，天然气沿上倾地层向上倾方向运移的过程，是随地层温度和压力不断降低、其运移速度逐渐增大的过程，如果有后续气体的加入，会使气体长度增大，致使运移速度增加得更快。

The effectiveness of this method depends basically on two values,Гmin the search is faster for larger Гmin and the size of Pref (RE (the search is faster for less prefixes), where Гmin donate the shortest path from the initial state to a final state of the Nondeterministic Finite Automaton and Pref the prefixes of length Гmin for all the strings matching the regular expression. The size of Pref can be exponential in m and for multiple expressions matching the Pref will be much larger.

现有的正则表达式搜索算法性能较好的是多模式过滤类型的算法，此类算法严重依赖于两个因素，从NFA的初始状态到终止状态的最短路径Lmin和正则表达式所表达的语言的前缀集合Pref的大小，Lmin越长，搜索速度越快，Pref越大，搜索速度越慢。

Key Notes Within the nonlethal temperature range the most important effect on ectotherms of temperature is likely to be its effect on rate of development and growth.

在非致死温度范围内，温度对外温动物最大的影响很可能是影响了发育和生长的速度。当用发育速度对体温做图时，存在着一个直线相关的温度范围。

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。
