In Loess area, block cloddy was universal existence in farmland surface. The physical and chemistry properties of block cloddy in plow layer were researched in this study.

针对黄土地区农田土壤普遍存在块状结构体的现象，用蜡封法研究了块状结构体的松紧度以及用EDTA滴定法测定了结构体中水溶性Ca(上标 2+)含量。

PH potentiometric titration results show that products with high DS have excellent water solubility in wide pH range.

采用元素分析法确定了产物的取代度，并用FTIR、H〓NMR和X-ray等手段对产物进行了表征。pH滴定表明，较高取代度的样品在宽广的范围内具有良好的水溶性。

We collected Leishmania promastigotes,washed its with 0.01mol/LpH7.2 buffers ,smashed its,and then measured protein content and titrated work concentration.2.We tested Kala-azar patients"serum and healthy persons"serum of epidemic area by ELISA. The results of three antigensmethods were the same, work concentration of serum was the same(l :100).Results:The protein content of three antigens is, 901 strain with 1000ug/ml,801 strain with 960ug/ml and 951 strain with 1100ug/ml. Suitable work concentration is, 901 strain with 10ug/ml ,801 strain with 12ug/ml and 951 strain with 11ug/ml.

1、抗原的提取：收集新疆不同地区分离得到的利什曼原虫前鞭毛体，经培养，用0.01mol/L pH7.2的磷酸盐缓冲液漂洗，超声粉碎，比色法测定其蛋白质含量，间接ELISA法滴定出抗原的工作稀释度。2、检测：用提取的三株抗原，分别进行间接ELISA法测定黑热病病人血清和疫区健康人血清抗体，并以肺结核病人血清、非疫区健康人血清做对照，三株抗原所用检测方法一致，血清工作稀释度均为1∶100。
