Most of them rely on the central limit theorem, that states that the mean of N independent realizations of a random variable with mean u and variance d^2 approaches a normal distribution with mean u and variance d^2/N .
在蒙特卡罗评估框架内大量的各种选择性算法已经被推出,他们中的大部分依赖于中心极限定理,一个均值为U方差为D^2的随机变量的N次独立实现的平均值接近于一个均值为U方差为D^2/N的正态分布。

Therelationship of the amount of catalyst and the ee% of product was seen to be negative nonlin-ear. Catalyst 3 was used in the enantioselective addition of diethylzinc to aromatic aldehydesand gave good results. The configuration of products was determined by the configuration ofthe catalysts' chiral carbon linked with hydroxy group. Using β- amino alcohols bearing only one chiral center as catalysts for the enantiose-lective addition were studied. D-N, N-dialkyl-2-amino butanol gave poor catalytic effect be-cause of their structure. The configuration of the product is the same as the catalyst. Anotherkind of β- amino alcohols - phenylglycine derivatives and valine derivatives have chiralcenter on the carbon linked with amino group. Catalyzed by-phenylglycine derivatives 6,7, 9, 10, the reactions gave satisfied results. The optical yields exceeded 80%.
在探讨了含有两个手性中心的β-氨基醇之后,选择了只有一个手性中心的β-氨基醇,一是手性中心为连羟基的手性碳原子:D-N,N-二烷基-2-氨基丁醇;二是手性中心为连氨基的手性碳原子:D-苯基甘氨酸衍生物和L-缬氨酸衍生物。D-2-氨基丁醇的催化效果不太好,这与其结构的空间位阻较小有关系,反应产物与连羟基手性碳构型一致;由苯基甘氨酸和缬氨酸出发合成五种β-氨基醇6-10,研究了不同ee%的-6作用下的二乙基锌-苯甲醛加成反应,发现该催化剂具有不对称放大效应;-7,9,lO的催化效果也比较令人满意,光学产率80%以上,所得产物构型与催化剂构型一致。

METHODS: Eighty cases who had undergone renal transplantation were randomly divided into 2 groups:① preemptive therapy group (n=40), who were given ganciclovir (GCV, 250 mg/d) once at least 1 CMVPP65 positive cell per 2.0×105 PBL till the antigenemia became negative.② Control group (n=40), who were given universal twoweekprophylaxis with GCV (250 mg/d) beginning at the 3rd week after transplantation. A 3month followup was conducted and the efficacy and costeffectiveness of the 2 groups were compared.
