1·Based on the fuzzy comprehensive DRASTIC evaluation method, the vulnerability of unconfined water in Songnen Plain is evaluated.
运用基于DRASTIC的模糊综合评价方法，对松嫩平原潜水的脆弱性进行了评价。
2·The water table of the unconfined aquifer near the coast fluctuates following the tide movement, the aquifer also exchanges water with the sea.
近岸含水层水位随潮水的波动而波动，同时还与海水之间发生着水量交换。
3·The water content of the soil sample was changed by drying and humidification process. After different freeze-thaw cycles, the unconfined resilient moduli of the soil sample were tested respectively.
通过风干和增湿改变试件的含水量，并经历不同的冻融循环次数后，分别测试土体的无侧限回弹模量。
