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。

Methods: Cadmium column and acid-base resisting burette with knob-operated control were used to determine nitrate and nitrite in milk product.

目的：建立镉柱还原分光光度法测定奶制品中硝酸盐和亚硝酸盐的方法。

The uncertainty of measurement for the determination of chloride content in water by silver nitrate titration method was evaluated.The influence of the factors on the uncertainty of measurement for the determination of chloride content were analyzed, including repeatability of measurement results, burette, the concentration of standard solution, etc.

氯化物进入地表水中有自然和人为两种因素，岩石风化可使自然界中的氯化物进入地表水中，同时工业及生活污水的排放和海水倒灌也会给地表水中引入大量的氯化物，地表水中氯化物含量的变化是监测排污和咸潮影响的重要指标。
