查询词典 bichloride

Experimental results show that hydrogen can be produced by the reaction between nitric acid with a given concentration and aluminum handled by means of mercuric bichloride solution under room temperature. Whereas hydrogen is not detected without aluminum handled by mercuric chloride solution.

研究发现，室温下用去膜并经氯化汞溶液处理过的铝箔与一定浓度的稀硝酸作用可产生氮气，而未经氯化汞溶液处理的铝箔与稀硝酸作用几乎检测不到氮气的生成。

In the batch process of chlorination, the byproduct -benzyl bichloride comes out when the benzyl chloride content reaches 20%, which causes low single-pass chlorination depth, high consumption of raw materials, much operation cost, and serious contamination to the environment.

釜式反应生产过程中，氯化苄浓度达到20％时即有副产物二氯化苄产生，使单程氯化深度较低，原料单耗和操作费用高，环境污染较重。

The experiment of pretreatment shows that polyurethane foam can be washed clearly in both organic and chemical unoil, good effects of coarsening can be gained only if polyure foam can be squeened repeatly and uniform mass loss between 2.0 and 3.0mg·cm~(-3). The result of activation is perfect even if the cheaper silver nitrate instead of expensive palladium bichloride is used as active agent in the experiment. The influence on quality of chemical plating, conductivity, depositon rate by the kinds of reduction, silver contents, PH and stabilizing agent was studied.

预处理实验结果表明：采用有机除油和化学除油即可清除聚氨酯泡沫表面油污；反复充分挤压泡沫，控制聚氨酯泡沫均匀减重2.0～3.0mg·cm~(-3)可获得良好的粗化效果；用硝酸银型代替氯化钯做活化剂，并施以适当的工艺同样可取得良好的活化效果。

Using tin bichloride-glycerol mixed solution as reductant,the determination method of phosphorus content for bioceramic base-material-β-calcium phosphate with phosphomolybdate blue spectrophotometry has been established.

以二氯化锡-甘油混合液作还原剂，建立了用磷钼蓝分光光度法测定生物陶瓷基材β-磷酸钙中磷含量的方法，确定了最佳测定条件。
