It is said that the Five Mountains comes back not looking at a mountain , think that I grow up stepping off that one piece of small basin hometown, think that I Deng Shang "am able to pawn a mausoleum extremely " Tarzan,"as soon as take numerous small mountain" Mount Huangshan into self's arms, still have that "nine eighteen wrong curved " Wu Yi Shan City , answer that Weng Shan , mountain be still that mountain going beyond the limit looking at after one's death again, being only this moment mountain already looks like one advanced old monarch attaining the wisdom, His posture trying to be higher than God cannot but let me sigh with regret , lament on my insignificancy with sighs , lament on my ignorance with sighs.

有道是五岳归来不看山，当我长大走出家乡那一片小盆地，当我登上"会当陵绝顶"的泰山，"一揽众山小"的黄山，还有那"九曲十八弯"的武夷山，回过头再看身后的那座翁山，山还是那山，只是这时候的山已经像是一位得道高深的老君，他那欲与天公试比高的姿势不能不让我慨叹，慨叹我的渺小，慨叹我的无知。

And Mach number (to 0.88), and changing test section configurations. The significant results have been obtained.

首次开展了大堵塞比高M数和变试验段截面的探索性研究，取得了不同程度的成功，并获得了极有价值的研究成果。

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。
