Based on the different reaction results with-menthyl,-8-(2-naphthyl)menthyl or-8-phenylmenthyl as the chiral auxiliary, it is was proposed that the possible p -stacking effect between the aryl of chiral auxiliary and dienyl group of α,β-unsaturated esters is involved in the diastereoselectivity of these reactions.

该反应手性辅基易于回收、选择性好，产率高，这一工作为合成多取代的光学活性乙烯基环丙烷衍生物的提供了一种较为简便的方法。

In the experiments, detection rate and reaction time were measured to evaluate the visual performance of human eyes at three mesopic light levels0.01, 0.1 and 1 cd·m~(-2 with targets of two visual angles (10 and 2°) at two observing eccentricities (0°, 10°). There generated more than 30,000 single measured data and analysis with statistical and computer methods were done.

本论文的实验选用了探测率和反应时间作为评价人眼在中间视觉状态下视觉功能的主要参数，分别在3组典型的中间视觉亮度作为背景亮度0.01，0.1和1 cd·m~(-2和2组不同视场角的目标(10'和2°)以及2组不同的观测偏心度(0°，10°)条件下，先后在中国和德国进行了30，000多个数据采样，并运用计算机技术进行统计分析和研究。

The results indicate the effect of light level, visual angle and eccentricity on detection rate and reaction time at mesopic region; shows series of spectral luminous efficacy drawn out from the experimental results since monochromatic stimulus was used; proves that the results from performance-based method are in essence compatible with those from bright-matching method, since both of them are in accordance

本论文实验和计算结果确定了背景亮度、视场角和偏心度对人眼探测率和反应时间的影响程度；根据视觉功能的基础和实验中选用单色光谱作为视觉目标所得到的数据推导出人眼在中间视觉状态下的系列的光谱光视效率函数；本文研究结果证实了基于视觉功能法和视亮度匹配法所获得的光谱光视效率函数在本质上的一致性，它们都能反映出随着亮度降低而产生的浦尔金耶偏移效应(Purkinje-shift)，但本论文所采用的基于视觉功能法还能反映出人眼视觉信息处理中的颜色通道效应。

The analyses of size distribution and water absorption ability showed that sedimentary phase carbonates has the highest water absorption ability to form coarser pseudo-particle compared with metamorphous phase carbonates.

由於沈积岩相的菲律宾石灰石的结晶颗粒间压密程度较变质岩相的台湾大理石与日本大理石松散，在烧结过程中，容易分解并与铁矿反应，生成铁酸钙之烧结矿相比例较高，因而提升烧结矿之产率。

The experimental results show:(1) The water in South Fei River has been comtaminated, especially in industrial and residential part.(2)Vicia faba(QI_1) is sensitive to mutagen, and liner relation between the freguency of micronuclear cell in the root tip cells of Vicia faba(QI_1)and concentration ...

结果表明，南淝河水体已被污染，尤其以工业区和居民生活区污染严重；启豆Ⅰ号对诱变物反应敏感，水环境中污染物浓度与微核千分率呈线性相关，因此启豆Ⅰ号作为微核监测技术的实验材料是可靠的。

The results showed that in the presence of ,the monobromination had many advantages,such as rapid reaction speed,easy to operation and separation,high yield and selectivity,and so on.

实验结果表明，在离子液体[Br3]存在下，溴化反应不仅速度较快、温度缓和、操作简便，而且产物的产率高，易分离，对环境更友好。

The yields were 67～89% and 61～90% respectively, and the ees were 66～99. 9% and 68～99. 9% respectively (except for trans-5-decene and ally naphthyl ether). With trans-stilbene as the substrate, chiral ligands and OsO〓 could be recovered and reused five times in the AD reaction with high catalytic activity and stereoselectivity.
