Objective:To explore the changes of hexosamine and phospholipids in gastric mucosa of rats with open abdominal trauma after seawater immersion.

目的探讨大鼠腹部开放伤后海水浸泡的胃黏膜中氨基己糖和磷脂的改变。

Unlike traditional latex or acrylic coatings, polyurea, as a suitable waterproofer even under seawater immersion, is in no way influenced by ponding water, which is very often on existing roofs.

优于丙烯酸防水涂料的主要一点是聚脲的耐积水性能，而屋面积水在国内非常普遍。
