In chapter three, the activating agents of ytterbium have been examined. Barbier-type reaction promoted by ytterbium metal was examined. The experimental results shown that the yield of Barbier reaction of imines with allylic bromide promoted by ytterbium is higher than that of aldehydes and ketones with allylic bromide under the same reaction conditions. In this chapter, the reductive cleavage of Se-Se and S-S bond induced by ytterbium metal was also studied.

首先研究了金属镱的活化剂以及活化方法，接着考察了金属镱促进的Barbier反应及其在合成高烯丙基胺和高烯丙基醇中的应用，以及影响该反应的主要因素；究了金属镱促进的二硫醚和二硒醚的S—S键和Se—Se键的还原断裂，继而与氯代烃，胺基甲酰氯反应生成相应的硫醚，硒醚，胺基甲酸硫代酯和硒代酯。

The software adopts the B/ S and C/ S together in the frame, focusing the humanity design mode in graphical interfaces design basing the point that the network manager will use it easily.

在软件架构上采用了B／S、C／S相结合的方式，在图形界面设计的人性化方面做了尝试，出发点是方便网管人员的使用。

To analyse the signal test, binomial probability law was used for significance testing of signals in the images emitted from human hand in different period of time, which proved that human hand can emit ultra-weak bioluminscence, the photon inensity emitted from fingers is in the range of 300～550 photons/s and the whole hand in 850～1200 photons/s.

为分析图像中的信号检验，二项分布被用于人手不同时间累积发光图像中的信号显著性检验，证实人手存在超微弱生物发光，手指的发光强度在300～550photons／s范围内，全手的发光强度在850～1200photons／s范围内。

Marvin Gaye's 1973 album, Let's Get It On, is a marvel of sexual blandishment every bit the artistic equal of, say, John Donne's best seduction poems.

对於Marvin Gaye应该不用多做介绍。在他专辑中我最喜爱的就是"Let's Get It On -让我们来XX -"。

An equivalent approach4 is to compare the average distance,1/3, among particles of mass m, contained in a volume V and at temperature T, with the associated de Broglie's wavelength A2mkT, k being Boltzmann's constant!

等效approach4 将比较平均距离，1/3，在大量之中m 微粒，包含在容量v 和在温度T，与伴生 de Broglie。。s 波长A2mkT， k 是Boltzmann。。s 恒定！

During Machiavelli's early years as a diplomat, he was in contact with Borgia and witnessed Borgia's rule first hand.

在Machiavelli's 早年期间作为外交官，他直接是与Borgia 和被目击的Borgia's 规则联系。

F where S is a bounded closed set and f is continuous over S.

f此处S为R〓中的一个有界的闭集，f为S上的连续函数。

Approaching the Brazil coast near Recife the current diverges, the N part continuing WNW towards the Caribbean Sea (see 2.15) and the S part turning S as the warm Brazil Current.

Approaching在Recife附近的巴西海岸潮流分流， N零件继续往加勒比海的WNW (参见2.15)和转动S的S零件作为温暖的巴西潮流。

"Breadboard" test, a more formalized prototype, called the XAF, was installed on the battleship U.S.S.
