We have prepared many different polyacids, studied factors affecting the properties of these materials, and evaluated the property of waterresistance and X-ray penetration of these materials.
我们合成了多种聚合酸，探讨了影响聚合酸-玻璃粉复合材料性能的因素，评价了该材料的透x线性和耐水性。

The mortar part inspects the influence on resistance to chloride ion penetration by different water-binder ratios, different added materials, different sand-binder ratios and different ages;
砂浆部分研究了不同水胶比、不同掺和料、不同龄期、不同砂胶比分别对其抗氯离子渗透性能的影响；
