The drawing testing、cutting testing and fracture analysis of high chromium casting iron－carbon steel's compounding interface showed: the compounding interface has higher strength and the impact toughness of composite plate is about 5 times of high chromium casting iron, which make it possible to make full use of high chromium casting iron's excellent wear resistance in practice under the high impactive condition.

需要特别指出的是：复合板的冲击韧性高铬铸铁5倍以上，这为高铬铸铁在高冲击工况发挥其优异耐磨性能提供了可能。采用试验方法生产的双金属复合板件正在矿山冲击较大的工况下使用，实际使用时间已经超过以前使用的高锰钢的使用寿命，目前仍在继续使用中。

Trivalent chromium and hexavalent chromium are the predominant chromium species in the natural environment.

其广泛的运用在各大工业中，也因此铬的职业暴露所造成的危害为人所注目。

On the base of structure and constitute analysis of organic chromium of nicotinate chromium and 〓, which all have evidently biological function, it reports the preparation of the first type of four kinds new organic chromium complexes . H〓O,. H〓O,,, in which Salen schiff base ligand and nicotinate or isonicotinate, or pyromucate, or benzoate ligand are contained simultaneously.

根据具有明显生物学功能的有机铬——烟酸铬和〓配合物的组成及结构特征，合成了第一类四种含有希夫碱Salen配体和烟酸、异烟酸、呋喃甲酸和苯甲酸的有机铬，其组成分别为。H〓O，。H〓O，，。

Studies on mechanism of Biosorption and toxicity of chromium indicated that Biosorption was contained of surface adsorption, transport across cell wall and membrane, and bioaccumulation. Further more, bioaccumulation played significant role in total Biosorption capacity, it attainted 70.6%. And the resistance on chromium of cell wall was perfect, breakage exceeded of 0.1 nm was not conduced by 300 mg/L chromium. Detoxifcation ability would be facilitated by activated sludge.

对吸附机理和毒性的初步探讨结果表明，菌体对铬的吸附由表面吸附、跨壁膜运输和体内积累组成，其中体内积累对吸附的贡献值最大，达到总吸附量的70.6%；细胞壁对铬毒性的抗性理想，300mg/L铬不会对细胞壁产生0.1nm以上的形态破坏；活性污泥的联合使用有助于铬的还原。

While high quality deposition from trivalent chromium electrolyte could only be sustained for short periods and thin deposits obtained of decorative value only, it is difficult to substitute heaxvalent chromium plating in engineering electrodeposits by trivalent chromium plating at all.

因此，本文在电沉积出镍-铁合金纳米晶的基础上，采用脉冲电沉积的方法研究了在三价铬体系中获得纳米晶铬和铬-镍-铁合金纳米晶厚镀层的工艺及其基础理论，以期解决三价铬镀液完全代替六价铬电镀的难题。

Additionally, the nanodots were measured by EFM, and the experiment indicated that the charge of chromium oxide is negative. As the height of chromium oxide increases , negative charge of chromium oxide increases.

此外，我们用静电力显微镜观察铬氧化点的静电荷分布情形，发现在铬氧化点内的静电荷为负电荷，并且随著铬氧化点高度的增加而变多。

In skin exposure experiment, we found urinary chromium concentrations in post-exposure overtly higher than that in pre-exposure when Wistar rats were exposed to chromium VI and chromium III at 100 mg/L simultaneously.

而在浓度100 mg/L的皮肤暴露途径下亦发现，同时暴露到Cr+Cr时，尿中的总铬平均浓度明显的高於未进行实验前的尿中总铬浓度，故可推知共同暴露到Cr+Cr时，可能较个别暴露易於经由皮肤吸收而进入到体内。
