Silane, as an extremely hydrophobic material, changes concrete surface from hydrophilic state to hydrophobic state by spraying on the surface of concrete.It has the ability to block the extemal corrosive medium to improve the durability of concrete.Three types of strength grade of concrete (C30, C40, C50)were designed, after spraying with silane on the surface of concrete, to measure the penetration depth of silane and the influence on water-absorption rate, liquid-absorption rate, chloride ion diffusion coefficient and salt frost resistance.

目前熔盐电解法制备稀土金属及其合金技术已经取得长足的发展。本文综述了电解制备稀土金属或合金过程的电化学研究的相关基础数据,对在氟化物熔盐体系中已经开展研究的8种稀土元素(La,Ce,Pr,Nd,Sm,Gd和Y)的研究现状、结果进行了总结。
金属钐是重要的稀土元素之一，是制备高性能稀土永磁材料、储氢材料、核控制材料等高技术材料必不可少的基础材料。目前，镧热还原蒸馏法是工业生产金属钐的唯一方法，属间歇生产，设备要求高、生产周期长、加工成本很高，因此，科技工作者一直在探索廉价金属钐生产工艺的可能性，其中熔盐电解法是生产稀土金属及合金最主要方法，其生产成本最低，但由于Sm的变价特性，工业上采用熔盐电解法制备金属钐及其合金一直未获得成功。
