We take biodegradation experiments toward three colonies with different density phenolic waster water, and test their rate of phenolic degrading and speed of bacteria growth in different time period. The results show that the rates of pheolic degrading are more than 95% in 500mg/L phenol and 250mg/L cresol culture solution.

对这三株菌种进行不同浓度的含酚废水降解试验，测定其不同时间段的酚降解率和菌株生长速度，结果表明BP-1，BP-2，BP-3菌在500mg／L的苯酚，250mg／L的甲酚溶液中的降酚率均达到了95％以上。

And the relationship between sex of cucmber and isozyme were analysed. The results indicated that, in terms of numbers of band and activities of peroxidase and superoxide dismutase were significantly induced after treated with silver nitrate and ethephon at 300mg/L and 200 mg/L in cucumber leaves, respectively.

研究表明，300mg·L〓硝酸银和200mg·L〓乙烯利处理黄瓜茎尖后，叶片中过氧化物酶和超氧化物歧化酶两种同工酶的酶谱带数和酶活性均明显受到诱导，而过氧化氢酶几乎不受影响。

It was rev ealed that:cuprite,malachite and tenorite are the three main kinds of copper-bea ring minerals which would be supersaturated when Cu concentration in the solutio n is high enough(higher than 0.0016 mol/L,0.0079 mol/L separately) under the stu dy conditions.Copper exists in the solution mainly as the species of CuCO3 ,Cu2+ and CuOH+.The corresponding content of CuCO3 would be decrea sed following the deposition of the copper-bearing minerals,nevertheless,Cu2 + and CuOH+ would be increased.

模拟结果表明，在土壤中常见的E h和pH及研究区的年平均温度条件下，溶液中铜离子的含量达到一定的浓度时，可以生成赤铜矿(当Cu≈00016 mol/L)、孔雀石及黑铜矿(当Cu≈0 0079mol/L)等次生矿物，溶液中Cu的存在形式也发生了变化，即CuCO3所占的比例不断减小，而Cu2+和CuO H+的含量则相继增高，且Cu2+的增幅大于CuOH+。
