The four-colour offset printing press Heidelberg, if a printing plate surface is a zinc or zinc or iron, iron will and Bailers in acid solution from chemical replacement reaction secable, nitrous oxide, drum body cannot ¤j¤?¤? backing and a printing plate, such as the drum surface long soaked in the acid corrosion, instilla secable, a printing plate chrome coated drum for restructuring into it or nickel does not result in more accidents.

四色海德堡胶印机，如果印版滚筒暗地是涂锌或铁，那么锌或铁城市与水斗溶液边的酸起化学置换不正答生锈、氧化，滚筒体不克不及紧贴衬垫物和印版，如滚筒背恒久泡在酸液边，会爆发腐化生锈，印版滚筒体改成涂铬或镍不离不会爆发以上变乱。

The effects of the components of trivalent chrome passivation bath on the appearance and corrosion resistance of the passivating film are investigated.

研究了三价铬黑色钝化液组分对钝化层外观和耐蚀性的影响。

Further, said chrome-free passivating solution may comprise one or more complexing agents.

The results show that the addition of accelerators to the treating bath will accelerate the coating formation, and the added ammonium salt and chloride will change the Ce content in the coating from 5.93% to 4.15% and 9.27%, respectively. The added accelerators of ammonium salt and chloride could also increase the coating anti-corrosion performance to 2.6 times and 6.6 times against that treated without accelerator, respectively, and increases the micro-hardness of the Al surface from HV68.8 to HV389 and HV450, respectively.

结果表明：处理液中添加成膜促进剂可提高转化膜的生长速度，并且添加铵盐、氯化物后转化膜的铈含量从5.93%改变为4.15%和9.27%；还发现添加成膜促进剂铵盐、氯化物后转化膜耐腐蚀性提高为原来的2.6和5.6倍，其中后者的耐点滴腐蚀能力优于传统铬酸盐转化膜，并且还可将铝合金表面的显微硬度从HV68.8增大至HV389和HV450。

These include mass ratio of metallic powder to chromium trioxide and technological parameters of paint throwing off , drying and sintering processes.

包括：金属粉与铬酐质量比、甩液、烘干和烧结工艺参数。

Therefore, the nickel impurity in the chromium-plating bath was determined using spectrophotometry, which was based on the reaction between nickel ions and diacetyldioxime, generating a red complex, in the presence of alkali and ammonium per-sulfate. The measurement was carried out in 3cm color-matching cells at a wavelength of 510nm, using the sample without chromogenic agent as the reference.

在碱性和过硫酸铵存在的条件下，镍离子与丁二酮肟生成水红色配合物，利用这一特性，以丁二酮肟光度法测定镀铬溶液中镍杂质的含量，以不加显色剂的试样作参比液，用3cm比色皿，在波长510nm处测定。

The surface of ultra high molecular weight polyethylene fibers was modified by the confected chrome acid treatment solutions.

利用自行研制的铬酸处理液对超高相对分子质量聚乙烯纤维进行表面改性，并利用扫描电镜、红外光谱和接触角、单丝强力试验对纤维的表面性能和强度的变化进行表征。

The results show that in the 1.0 mol/L sulphuric acid solution, the rates of swelling and breakage of emulsion liquid membrane decline and the extraction efficiency is 99.4%.

结果表明：在1.0 mol/L的硫酸含铬废液中，该体系具有良好的稳定性，液膜的溶胀率以及破损率明显降低，Cr的萃取率高达99.4%。

Before the test ,clean each filter by soaking in chromic acid mixture.

试验前，通过在铬酸混合液中浸泡方法清洗过滤器

Chromium-rich brewer's yeast can remarkably reduce the blood sugar of type 2 diabetes patients, which may be related to it can increase the effects of insulin or the sensitivity of receptor, but not to improve the insulin's excretion.

富铬酵母提取液具有较好的降低2型糖尿病患者血糖的作用，作用机制可能是提高胰岛素的生物效应，或提高胰岛素受体的敏感性，而不是促进胰岛β细胞分泌胰岛素。
