Phenothiazine 100μmol/L decreased about 40% of I〓 tail current elicited by depolarization shorter than 500msec, but only 30% of I〓 tail was inhibited during depolarization longer than 1000msec.

在短于500msec，+60mV的去极化时，100μmol/L酚噻嗪使约40％I〓尾电流下降，而在长于1000msec的相同膜电位水平去极化时，相同浓度的酚噻嗪只能使30％的I〓尾电流受到抑制。

Ten secondary metabolites in phloem of different strains of poplars were extracted by different chemical methods and their contents were determined.

摘要通过不同化学方法提取并分析了不同品系杨树韧皮部10种次生代谢产物的含量及含量差别，研究了不同制样方法对单宁、酚类及酚酸产物含量提取结果的影响。

Recent researches show that conventional water treatment processes can not remove nonylphenol efficiently, while physical processes such as activated carbons or organic-montmorillonite adsorption and chemical processes such as sonolytic degradation, electrochemical oxidation or photodecomposition show effective decomposition on nonylphenol in water.

研究表明自来水厂的常规处理工艺对于壬基酚的去除有限；而活性炭、有机蒙脱土吸附等物理方法，超声声化、电化学氧化、光分解等化学方法可有效降解水中的壬基酚。

Methods Synaptosomes was made from hippocampus and incubated with artificial cerebrospinal fluid. 30μmol/L propofol, 50μmol/L picrotoxin or both was added into aCSF. Intralipid was administered as solvent control and any drugs was applied in control. To observe Ca~(2+)-dependent release of glutamate and GABA, dihydrokainic acid and nipectic acid were added into aCSF.

制备大鼠海马突触体，随机分为5组：PTX组加入印防己毒素使其终浓度为50μmol/L，Pro30+PTX组加入终浓度为30μmol/L的丙泊酚和50μmol/L的PTX，Pro30组加入终浓度为30μmol/L的丙泊酚，溶剂对照组加入脂肪乳，空白对照组不加入上述药物。

All thanks to the Plastic Age, now scientists say that a common 18ingredient in most plastics, called Bisphenol A, or BPA, causes reproductive harm in rats at levels below what most humans are exposed to every day.

全亏了这个塑料时代，如今，科学家们说大多数塑料里的普遍成分——双酚A，简称BPA，会损害鼠群的生殖系统，而大多数人每天接触这种造成损害的双酚A的量竟比鼠类接触的量要高。

The stronger antioxidant capacity of tea polyphenol is due to the presence of phenolic compounds, such as catechins in its composition.

茶多酚之所以具有很高的抗氧化活性是由于酚类化合物的存在，如在它的结构中存在儿茶素。

In this paper,the content of polyphenols in apple pomace was measured and processing conditions of polyphenols in apple pomace were optimized with mono-factor analysis and orthogonal test.

本文对苹果渣多酚含量测定方法进行了研究，通过单因素实验和正交实验优化出苹果渣多酚提取工艺。

This complex reaction was phenolic electronic substitution reaction, so reaction rate was related with the positive electricity of pro-electronic reagent, as well as the form of aromatic hydrocarbons. Rates of chlorination of phenol and 2-monochlorophenol were faster in alkaline water than that in weak acid water, so 2,4-dichlorophenol and 2,4,6-trichlorophenol formation concentrations increased with the reaction time.

该复合反应属于酚类电子取代反应，反应速率与亲电子试剂的阳电性以及芳香烃的形式有关，碱性水环境中氯取代苯酚和2-一氯酚的速率要快于在弱酸性水环境；随着pH的升高，2，4-DCP和2，4，6-TCP的生成浓度也不断增加。

Resent studies have highlighted the effect of propofol infusion syndrome. Nevertheless, studies of mechanisms of PRIS are still few. Propofol infusion syndrome is a rare and often fatal syndrome described in critically ill patients undergoing long-term propofol infusion at high doses.

异丙酚输注综合征(propofol infusion syndrome，PRIS)是指对危重患者长时间、大剂量静脉输注异丙酚后引起的严重代谢性酸中毒、心衰、横纹肌溶解和肾功能衰竭等严重并发症，甚至导致死亡。

The results showed that the amorphous iron oxide has highly catalytic activity. The intermediate products are pyrocatechin, hydroquinone, benzoquinone and low-grade fatty acid. The mechanism of catalyst oxidation is assumed that the free radical OH attacks benzene cycle at the adjacent position and para-position of OH on phenol so that the benzene cycle is opened and low-grade fatty acid is produced and transformed into CO2 and H2O.

结果表明，非晶铁氧化物催化剂在催化氧化降解苯酚时具有较高的催化活性，苯酚降解的中间产物有：对苯二酚、邻苯二酚、苯醌和低级脂肪酸，其降解机理是羟基自由基攻击苯环上OH的部位或对位而使苯环开环，生成低级脂肪酸，并最终转化成二氧化碳和水，从而使苯酚得以降解。
