含硫的

Stone is from rock, and rock is consist of the mineral, the mineral contain iron is the source of the iron in stone products , iron element spread widely in natural world, but most of them appear to be compound, iron element is belong to medium activity metal, under high temperature is easily to be strongly acted with oxygen, sulfur, chlorine, and easily dissolve in abio-weak acid solution and strong hydrochloric acid solution, at the same time, the strong alkali solution also corrade the iron.

石材是岩石经加工后所产生的制品，岩石是由矿物组成的，其中含铁矿物是石材中铁质的来源。铁元素在自然界中分布甚广，但大多以化合物的方式出现，由于铁元素属中等活泼性的金属，在高温下易和氧、硫、氯等元素发生强烈反应，并易溶于无机稀酸和浓盐酸的溶液中，同时浓碱溶液也易侵蚀铁。

Carbon disulfide, dialkylamine, antimony trioxide have been used to synthesize the other organic antimony compounds-dialkyldithiocarbamate. The optimal technological conditions and purificating method have been studied in detail.

以二硫化碳、二元仲胺、三氧化二锑为原料合成了结构为Sb-〓的另一类含Sb-S键的有机锑化合物，通过大量的实验探索，详细研究了各种二烷基二硫代氨基甲酸锑的最佳合成工艺条件及产品的提纯方法，为该类化合物的制备提供了一种工艺简便，收率较高的合成工艺途径。

A pentacarbonyl complex (3) isolatedfrom the same reaction from which the complex (1) is obtained, whose accuratestructure is yet known, is preliminarily studied.

对从含吡啶基团的二硫醇三齿配体与Fe_3_(12)的反应中得到的另一个准确结构有待确定的五羰基化合物(3)进行了初步的性质研究及表征。

The literature about the synthesis of the ion exchange and chelating adsorbents used in the off-line separation and preconcentration of the noble metals and the development of the on-line microcolumn separation and preconcentration of the noble metals were reviewed. Four silica gel-based adsorbents with rhodanine, 2-mercaptopyrimidine, 2-mercaptothiazoline and isophenylthiourea as the functional groups were first synthesized and applied to the on-line separation and preconcentration of silver, gold, palladium and platinum for their FAAS determination.

本论文在回顾螯合吸附材料的合成及其在贵金属的离线和流动注射在线预浓集分离发展状况的基础上，首次合成了含罗丹宁、2-巯基嘧啶、2-巯基噻唑啉和异二苯基硫脲等四种以硅胶为载体的螯合吸附剂，并用于银、金、钯和铂的流动注射微填充柱在线预浓集分离、火焰原子吸收光谱分析。

The experiment result show that desulfurization efficiency declined with the increase of flue gas flux and SO_2 inlet concentration; desulfurization efficiency added with the enhance of Ca/S molar ratio, flue gas humidity, the moisture content of calcium sorbent, desulfurization efficiency also increased after adding activated vapor, superinducing additive, inflicting applied voltage.

试验表明：随着烟气流量，SO_2进口浓度的增加，脱硫效率降低；随着钙硫比，烟气含湿量，石灰含水率的增加，脱硫效率增加：随着活化蒸气的通入，外加添加剂的加入，外加电压的施加，系统的脱硫效率增加。

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。
