wet mechanical

The comprehensive tests of the mechanical properties showed that both the tensile strength at break and yield strength met the requirements of engineering plastics, and the Izod and Charpy impact strength in dry and wet state was obviously improved.

综合力学性能测试表明，材料的拉伸断裂和屈服强度符合工程塑料的要求，干态和湿态下的Izod、Charpy冲击强度得到显著提高，接近国外超韧聚酰胺66工程塑料水平。

干湿法制备异形PAN原丝及其力学性能的研究

Based on the fast freeze-thaw test, the alkaline resistance test, the water immersion test, the wet-thermal exposure test and artificial accelerated aging test, the influence of the corroding environment on the mechanical behavior of fiber reinforced polymer ( FRP) laminates and adhesive was studied.

通过快速冻融试验、耐碱性试验、浸水试验、湿热暴露试验、人工加速老化试验，研究了腐蚀环境对纤维增强复合材料（FRP）的复合体及粘结剂力学性能的影响。

Alkali treatment can increase the ratio of dry and wet mould mycelium pellet and reinforce its mechanical strength, but alkali treatment can not improve adsorption capacity of Pb~ ( 2+).

碱处理可以增大菌丝球的干湿比，提高其机械强度，但并不能提高其对Pb（Ⅱ）的吸附能力。
