1·A photovoltaic device includes an electron accepting material and an electron donating material.

光伏器件包括受电子材料和给电子材料。

2·When an organic molecule like electron donating pyridine adsorbs on the surface, cations get reduced due to charge transfer.

当一个有机分子如电子给予体吡啶吸附在表面上时，阳离子由于电子转移而还原。

3·The groups in ring of benzaldehydes, no matter they are electron withdrowing or electron donating except of hydroxy, do not seem to have much effect on the yield.

羟基处于醛基邻位和对位的苯甲醛与几种苯乙酮衍生物的缩合，多数没有得到预期的产物，或收率极低；苯乙酮环上的羟基对缩合反应影响很大，羟基越多，缩合越困难。

4·It was found that introducing electron donating groups, such as alkyls, weaken the electron accepting ability of C60 and make its first reduction wave shifted to more negative position.

结果发现，引入推电子基团，如烷基，会使C60得电子能力降低，第一个还原电位有较大的负移；

5·The layer including a luminescent substance has a composite material which includes an organic compound, and an inorganic compound showing an electron donating property to the organic compound.

包含发光物质的层含有包含有机化合物和对所述有机化合物显示给电子性能的无机化合物的复合材料。

6·Some of the dyes react strongly to electron-donating molecules, for example.

某些染料的会对电子基分子强烈反应，例如。

7·So it is very necessary to study the characters and extend applications of this kind of conjugated enynes with electron-donating substitutes.

因此，深入研究含有供电子基团的共轭烯炔化合物各种性质，扩展其在各领域上的应用都是非常必要和有意义的。

8·The dinitrobenzene with electron-withdrawing group can be hydrogenated much easier than the dinitrobenzene with electron-donating group.

含有吸电子基团的二硝基苯类化合物反应活性明显高于含有供电子基的二硝基化合物的加氢反应；

9·The effect of the electron-donating groups on the electronic spectrum was investigated.

探讨了给电子基团对电子吸收光谱的影响。

10·Electron - withdrawing 2 - substituents and electron - donating 3 - substituents of the phenyl ring are favorable for increased herbicidal activity.

苯环2位是拉电子基，3位是给电子基有利于提高除草活性。
