喘息型病毒性肺炎患儿除CD+4/CD+8较非喘息型病毒性肺炎高外，其他各项淋巴细胞亚群差异无明显统计学意义。

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。

Cd contents in overground and underground part (0-10, 10-20cm) of 19 kinds of turf grasses which planted in Cd-contaminated soil were analyzed and determined.

方法］对种植在镉污染地19种草坪草的地上部分和地下部分(0~10、10~20cm)的含镉量分别进行了分析测定。
