1·The thixotropy and dilatability of similar soft soil are studied and the thixotropy-testing curve is drawn.

同时，研究了类软土的触变性，得出其触变试验曲线。

2·The formation ratio of the present invention is high, damp-absorbing and dilatability is low, usage is convenient, nutrition is comprehensive.

本发明奶牛营养舔块成型率高，吸潮 性和膨胀性低，使用方便，营养全面。

3·The breaking strength and resilient-elasticity recovery of PTT fabric can be increased under suitable temperature and drawing ratio during heat setting, but its dilatability took worse.

选择适当的温度和拉伸比进行热定形，可提高PTT织物的断裂强力和弹性回复率，但其延伸性变差。

4·The influence of activator on strength and free linear dilatability and sulfate resistance of chemical waste gypsum - fly ash new road building material as well as action of water reducer are studied.

研究了激发剂对化工废石膏—粉煤灰新型道路建筑材料的强度和自由线膨胀率等性能的影响，以及减水剂的作用和新型道路建筑材料的抗硫酸盐侵蚀性能等。
