Prolonged overstimulation of dopamine receptors caused by methamphetamine may eventually cause the receptors to downregulate in order to compensate for increased levels of dopamine within the synaptic cleft.

甲基苯丙胺所引起的对多巴胺接受细胞的持续刺激可能最终会这些接受细胞变少，从而能应对神经键隙中大量的多巴胺。

These ingredients includes epidermal growth factor, hepatocyte growth factor, dimethyl sulfoxide, phenobarbital sodium and all trans-retinoic acid. We isolate and culture primary 10-weeks-old human fetal hepatocytes, observe hepatocytes form and its function markers. Inoculate hepatocytes with HBV Dane particles to observe if HBV susceptibility of fetal hepatocytes can be induced in vitro. To detect HBV covalently closed circular DNA within hepatocytes, we improve the existent PCR method.

基于上述假设，我们设计了10种培养条件，在自行设计的无血清培养基中添加不同的细胞分化诱导物，包括表皮生长因子、肝细胞生长因子、二甲基亚砜、苯巴比妥钠、全反式维甲酸等，分离孕10周龄人胎肝细胞进行原代培养，观测肝细胞形态及功能指标变化，并定时给予HBV感染，观察能否在体外诱导胎肝细胞出现HBV易感性；为检测肝细胞内HBV共价闭合环状DNA(covalently closed circular DNA，cccDNA)，我们改进了现有的PCR检测法。

The optimum conditions were reaction temperature 120°C, reaction time 20h, mole ratio of 5-chloromethyl-2-oxazolidinone and sodium phenolate 1:1. 3,5-Dimethylphenol and epichlorohydrin in sodium hydroxide were condensated to give l,2-epoxy-3-phenoxy propane, then the reation of l,2-epoxy-3-phenoxypropane and the carbamate afforded oxazolidinone in the yields of 69.0%~76.0%. The side reaction had been avoided effectively by the uses of the excessive epichlorohydrin and mixed catalysts.

用3，5-二甲基苯酚和环氧氯丙烷在氢氧化钠存在下缩合生成苯氧基环氧丙烷，然后和氨基甲酸酯反应生成噁唑烷酮，采用过量环氧氯丙烷和使用混合催化剂，有效的避免了副反应的发生，提高了噁唑烷酮的产率，产率69.0%～76.0%。

In this paper, WAXD was used to investigate a series of liquid crystalline and non liquid crystalline sequential copolyester, which was synthesized from 1,10 decanediol, 2,2 bis(4 hydroxyphenyl) propane and the mesogenic monomer 2 methyl 1,4 phenylene bis(4 chloroformyl) benzoate.

应用广角X射线衍射对2，2－双（4羟基苯基）丙烷，1，10癸二醇与2－甲基－1，4－苯撑双（4氯甲酰）苯甲酸酯的一系列共聚酯进行了研究。

Enzymatic synthesis of cefaclor from 7\|aminodesacetoxymethyl\|3\|chlorocephalosporanic acid (7\|ACCA) and phenylglycine derivatives using penicillin G acylase was studied.

以7-氨基去乙酰氧甲基-3-氯头孢烷酸(7-ACCA)和苯甘氨酸衍生物为底物，利用青霉素酰化酶酶促合成头孢克罗。

Sodium fatty alcohlo ether sulfate, S-80, fatty alcohol-polyoxyethylene ether and S-60 resulted in slow photodecomposition of rotenone in aqueous solution revealing a photo-extinction effect, sodium dodecylberzenesulfonate, tween-60, hexadecyl trimethyl ammonium bromide and poyl vinyl pyrrolidone made the photolysis of rotenone in aqueous solution fast showing an obvious photosensitized effect.

室内条件下研究了鱼藤酮水溶液存在不同表面活性剂时，鱼藤酮的紫外光降解，结果表明：脂肪醇聚氧乙烯醚硫酸钠、司本－80、长链脂肪醇聚氧乙烯醚和司本－60对鱼藤酮在水溶液中的光解速率表现出显著的光猝灭降解效应；十二烷基苯磺酸钠、吐温－60、十六烷基三甲基溴化铵和聚乙烯吡咯烷酮对鱼藤酮在水溶液中的降解表现出一定程度的光敏化作用。

By comparing the data of the photopolymerization of methyl methaerylate at 30℃ with those of benzoyl peroxide initiated polymerization at 60℃,it clearly shows that primary radical termination is more important at lower temperature than at higher temperature.

比较甲基丙烯酸甲酯在30℃的光引发聚合和在60℃的过氧化苯甲酰引发聚合的数据，可以看出，初级自由基的终止效应在低温时更为重要。

Then we tested the photosensitivity of POF whose core material was copolymer of azo-benzene and poly in experiment.

其次，对含偶氮苯和聚甲基丙烯酸甲酯共聚的纤芯材料的聚合物光纤光敏特性进行了实验测试。

From the alkaline portion, 2, 5-lutidine, isolated as its picrate, m.p.

后者则与Gross等所合成的8-甲基-1，2-苯茀可能相同。

The title compound C_(27)H_(23)FN_(4)O_(2)C_(2H_(5)OH was obtained by the reaction of 1-phenyl-3-methyl-5-pyrazolone with 2-fluorobenzaldehyde in ethanol in the presence of piperidine under microwave irradiation and recrystallization from ethanol.

标题化合物C27H23FN4O2(C2H5OH)是由2分子1-苯基-3-甲基-5-吡唑啉酮和1分子2-苯甲醛微波辐射4 m in，用乙醇重结晶得到。

My first article for Screen Power Magazine, which is to this day is the official magazine of Jackie Chan, was a DVD review of the Hong Kong actioner Gen-X Cops, starring Nicholas Tse and Daniel Wu.

我的第一篇文章为屏幕力量杂志，在对这天是Jackie Chan 正式杂志，是香港actioner Gen X 警察的DVD 回顾，担任主角Nicholas Tse 和丹尼尔吴。
