卤化物

Dromids is more abundant than sulphate in many oilfield brines, we shall consider them cations and anions.

在很多油田卤水中，溴化物比硫酸盐多。我们将其看作是阳离子和阴离子。

In this project, we have prepared conveniently Si-Mg 1,1-difunctional group reagents-α-silylvinyl Grignard reagents by hydromagnesiation of alkynylsilanes; Se-Br 1,1-difunctional group reagents-α-bromovinylselenides by hydrobromination of alkynylselenides; Sn-Br and Sn-I 1,1-difunctional group reagents by hydrozirconation of alkynylstannanes followed by halogenating reaction.

本项目通过炔基硅烷的镁氢化反应，方便地制得了Si-Mg 1，1-双官能团试剂-α-硅基烯基镁化物；通过炔基硒醚的溴氢化反应，方便地制得了Se-Br 1，1-双官能试剂-α-溴代烯基硒醚；通过炔基锡烷的锆氢化反应，继而卤代方便地制得了Sn-Br和Sn-I 1，1-双官能试剂。

In part one, a new method for the synthesis of nitriles by phase transfer catalytic reaction is introduced.

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
