The results show that all aluminum anodizing sludges were slightly neutral to acidic and mainly consist of more than 50% Al2O3; the similar total contents of Cu, Pb, Zn, Ni, Cd, and Cr in the 7 samples were found, namely, the concentrations of Pb, Cd were relatively lower, but that of Cu, Zn, Ni, and Cr were higher; the leaching tests indicate that all the samples were classed as nonhazardous wastes; but each of metals in the sample shows very different leaching behavior, possibly depending on their total contents and the final pH of leachates.

结果表明，铝型材污泥属于中性偏酸性物质，主要由Al2O3组成，含量在50%以上。各试样中Cu、Pb、Zn、Ni、Cd及Cr的总含量的分布趋势基本是一致的，其中Pb、Cd的含量较低，Cu、Zn、Ni及 Cr的含量较高。浸出毒性试验表明铝型材污泥属于非危险废物，但污泥中各重金属的浸出特性又各自不同，可能主要与它们在试样中的总含量和浸出液的最终pH值有关。

Results:The primary pulmonary carcinoma group PR was 84.6%,bronchodilation group CR was 100%,splenic superfuction group CR was 100%,oophoroma group PR was 100%.

It was observed in the Cr-Ni-Mo steels that the intergranular ductile fracture is caused by the reprecipitation of MnS particles in the steel with ordinary S content, and the overheating is also performed by the repreeipitation of AlN or VC particles along the prior austenite grain boundaries in one containing low S. Thus, a proposal seems to be made that the mechanism of overheating of Cr-Ni-Mo steels is related to the solution and reprecipitation of MnS, AlN or VC particles along the prior austenite grain boundaries.

MnS粒子的重新析出使普通硫含量的Cr-Ni-Mo钢发生沿晶延性破断，而AlN或VC粒子在高温奥氏体晶界的重新析出也能使低硫的Cr-Ni-Mo钢过热。
