200 forepart pregnant women with ASA Ⅰ～Ⅱgrade who free will stop gestation,they were divided into 4 groups randomly :P group was simplicity propofol; F group, T group and K group was mainlined fentanyl 0.75μg/kg,tramadol 1mg/kg,ketamine0.2mg/kg respective before propofol abduction, and continuous detected MAP,HR,SpO2 in the operation, and to note first dosage and total dosage of propofol, revival time, leave hospital time, ill reactivity in the operation.

200例ASAⅠ～Ⅱ级、自愿终止妊娠的早孕妇女随机分为四组：P组，单纯异丙酚麻醉组；F组、T组、K组在异丙酚诱导前分别静注芬太尼0.75μg/kg、曲马多1mg/kg、氯胺酮0.2mg/kg。术中连续监测MAP、HR和 SpO2。记录各组病人异丙酚的首剂量和总剂量、苏醒时间、离院时间及术中术毕不良反应的发生情况。

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。

In order to explore the mechanism of the resistance to cucumber damping-off induced by plant growth-promoting rhizobacteria CH1, the physiological and biochemical method was employed to study the changes in activities of Phenylalanine ammonia-lyase, Polyphenol oxidase and contents of ferulic acid, chlorogenic acid, lignin, phenolic compound and flavonoid of phenolic metabolism in cucumber roots pretreated with plant growth-promoting rhizobacteria CH1 and infected by Pythium aphanidermatum.

为研究植物生长促生细菌CH1诱导黄瓜对猝倒病的抗性的作用机制，采用生理生化的方法，测定了黄瓜根部酚类物质代谢中苯丙氨酸解氨酶、多酚氧化酶活性动态及阿魏酸、绿原酸、木质素、总酚、类黄酮含量变化。

Alkylphenols are applied widely as the rubber additives surfactants in domestic and industrial products, antioxidants and so on. As it's decomposer, nonylphenol has a steady chemical characteristics and exist widely in environment. As it's molecule structures are similar as 17beta-estradiol in human body, and it can combine with estradiol receptor simulating it, disrupt endocrine system and induce health damage effect. Many studies on environmental endocrine disrupting chemicals approved that NP have weaken estradiol functions.

烷基酚被广泛用作塑料增塑剂、农药乳化剂、纺织行业的整理剂等，作为其降解产物壬基酚(nonylphenol，NP)的化学性质稳定，环境分布广泛，由于其分子结构与人体内雌二醇的分子结构相似，许多环境内分泌干扰的实验研究结果证实壬基酚具有雌激素样作用，可以模拟雌激素与体内雌激素受体结合，干扰机体的内分泌代谢，导致健康危害效应。

Based on the endocrine disrupter characteristic of alkyl phenol compounds, the short chain alkyl phenol compounds still have estrogen hormone effect, and their environmental effect must be pay attention in the pollutant control of NP.

根据烷基酚类物质的内分泌干扰特性，短链烷基酚仍然具有雌激素活性，因此在壬基酚污染防治过程中应给与足够的重视。

It catalyzes the oxidation of dopa rapidly to dopaquinone, which in turn polymerize non-enzymetically into insoluble melanin.
