When the PEO molecular weight increased, the gel fraction, the degreeofswelling and the hardness of the PEO hydrogel films increased obviously as well.
当PEO分子量增加时,其水凝胶膜的凝胶分数、膨胀度和硬度亦明显增加。

Correctly determining the compaction degreeofswelling soil and lime soil road Banks and improving filling methods are important steps of road bank construction.
正确评定膨胀土灰土路基的压实度、改善填土施工工艺是路基施工中的重要环节。
