Work was also carried out. From numerous facts of ourprevious work, it might be seen that the stereoselectivity of aziridination viasulfonium ylides depends upon the sulfonium salts and C=X compounds. The moreactive the sulfonium ylide and C=X compound are, the more cis product is generated.Whereas, trans product will be major if the activity of the sulfonium ylide and C=Xcompound is low.

通过对以往工作的总结，我们发现，在经由硫叶立德途径的小环化反应中有一个经验规律：产物的立体选择性与所用的锍盐和C=X化合物有关，即锍盐和C=X化合物的活性增强，有利于形成顺式产物，反之，锍盐和C=X化合物的活性降低，有利于反式产物的形成。

After undergoing a chaotic region, the period number will add one, in the same time, magnitude of the subharmonic response increases in sequence as the rotational speed ratio increases. When the rotational speed is below the critical speed, the chaotic bands resulted directly from a perioddoubling bifurcation occur among the successive orders of superharmonic responses, then they can return directly to periodic motion by a reversed period-doubling bifurcation.

在转速小于临界转速的情况下，在分岔图中各个连续阶亚谐运动的转换区中分别都出现了经由一个倍周期分岔直接导致的混沌频带，后又直接由一个逆倍周期分岔转化为周期一的运动，同时在三个混沌频带之间都出现了幅值突跳的现象。

In a sense, human genes have surrendered their primacy in human evolution to an entirely new, nonbiological or superorganic agent, culture.

"" Theodosius Dobzhansky重申了"文化被认为不是内生于基因，而是经由人类互动而学习得来"这种传统观点。

For us to study and supplicate.

藏传佛教中，也有着大量的经文、仪轨，经由诸多崇高的大师一直传承下来，他们为我们留下了经典和仪轨，让我们去学习和祈祷。

These transformations are based on the mathematical relationships that describe the various map projections. Thus, a transformation converts the coordinates of one system to the coordinates of another .

而这些转换的过程是经由数学计算来描述地图上的各种规划，因此用这种方式将不同系统座标来作一个转换。

Visitors will be able to view into and through these tableaux as they pass by in the corridor.

观众经由走廊参观时可以欣赏到这组作品。

However, this function is through Taekwondo training and improvement.

不过，这种机能是可以经由跆拳道的训练而提高的。

Several research tools were utilized to collect data required for the research, including Questionnaires on students' background information, their English learning motivation and attitudes before and after the one-semester CEIC instruction, their response to CEIC, formal school achievement test results, selected interviews, and class observation, which were further triangulated with tape-recording, teaching journals, and the mentor teacher's class observation.

几个研究工具被运用在本研究里，例如：学生基本背景资料问卷，针对一学期的国语英语整合教学前后学生学习动机及学习态度的施测，研究后学生对於国英整合教学的反应问卷，学校正式的成就测验，个别学生深入访谈以及课堂观察。其中课堂观察会经由录音，教师教学日志，和辅导教师课堂观察来做三角验证。

The difference in solvent polarity environment between excited state intramolecular charge transfer and proton transfer states leads to a remarkable ESICT/ ESIPT coupled reaction. In polar, aprotic solvents, in contrast to a unique PT tautomer emission observed in 3-hydroxyflavone (3HF), dual emissions are resolved, consisting of ESICT and ESIPT bands.

不同於化合物3-hydroxyflavone只观察到异构物的质子转移萤光放射峰的结果，在极性、非质子酸溶剂里，我们会观察到3-hydroxyflavone衍合物有两个萤光放射峰，是分别经由ESICT与ESIPT两种不同路径个别的贡献。

She gently rebuff ed him, but agreed that they could be friends
