1. Structure of saturant soil worked by water erosion is easy to collapse, and finally leads to surface saving water and losing stability.

2. In this pcriod, the percentage of saturant fatty acids increased and that of unsaturant fatty acids decreased.

3. The results indicate that the saturant crosslinking density, the lowest degree of swelling of the PEO R-150 water-swollen hydrogel films produce an unfavorable effect on their machinery strength.

4. In this article an initial value resolving method is Presented for resolving the non-linear transient Process caused by saturant characteristic of some block of the system.

5. Whirlpool-type high pressure recycle water cooling, double-stage vibrating dewater and granular net filter system ensures the finished granular even, saturant and glossy.

6. The results of investigation into nucleation show that temperature and time have little influence on tne amount of saturant acid crystallized.
