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。

The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media. The dissolved weight of gold in 0.25 M thiourea solution with 0.05M Na〓SO〓 and 0.1M 〓 of pH 12. 5 by air at the temperature of 303K is 7. 8mg·cm〓 within 1hr.
在碱性硫脲溶金过程不起直接作用，而是通过S〓O〓来控制二硫甲脒有效形成的金在溶液中的混合电位；&混合电位&是影响碱性硫脲溶液溶金与否的决定性因素，在0.4V左右，有足够的推动力致使二硫甲脒氧化Au成Au〓，随后硫脲与Au〓络合形成稳定的络离子Au〓，从而使金快速溶解；温度为303K、pH为12.5时，在含0.05MNa〓SO〓、0.1M 〓及0.25M硫脲的溶液中，鼓入空气，金的溶解量在1hr内为7.8mg·cm〓；铜只有微量溶解，银、镍、铁则几乎不溶解。
