Mice in control group were administered intragastricly at a dose 0.01 mL·g-1 for 10 d;PL were administered intragastricly for 10 d;CTX were administered parenterally every other day for 10 d.

空白对照组每日灌胃给予蒸馏水0.01 mL·g-1；CTX为隔日腹腔注射给药；PL为每日灌胃给药，连续给药10 d。

First,the BP neural network to carry on the partial diagnosis to the fault information is used,then the fusion using the D-S evidence theory to the partial diagnosis result is carried on,and the final fault result is obtained.The introduction of D-S evidence theory increases the diagnosis result reliability and the accuracy,enhances the diagnosis algorithm compatibility.

首先用BP神经网络对故障信息进行局部诊断，然后利用D-S证据理论对局部诊断结果进行融合，进行全局诊断，得到最终的故障结果。D-S证据理论的引入，增大了诊断结果的可靠性和准确性，提高了诊断算法的适应性。

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。

The relati onship of neighborhood between optic disc hemorrhages and RNFLDs: in the availab le tridimensional photochrome, 23 occurrences in 15 patients (16 eyes) were foun d with cuneiform RNFLDs in the same quadrant, in which 22 was near the border of cuneiform RNFLDs.
