I是科学引文索引，主要收录的是国际上理科方向的文章。EI也是偏向于理科方向，但它收录的是会议论文。国际上还有一个SSCI，这个是偏向于文科的检索系统，之后被引入到中国就成了CSSCI，即南大核心期刊。关于难度：都比较难，因为SCI、EI和CSSCI 的收录方向不同，所以比较难度不具有科学性。反正，都很难。关于认可度：SCI、EI是国际期刊，CSSCI是国内期刊，自然SCI和EI的认可度比较高，如果一篇文章能够被SCI和EI 双检索的话，就更好了。关于加分：很多人发文章是为了加分评职，根据我多年的经验来看，SCI加分最多，有的单位EI和SCI是平级加分，有的单位EI加分稍低，CSSCI的加分都低于国际期刊。
SCI和EI同是国际学术界权威的检索系统，两者侧重点不同，sci自然科学类的，侧重方法原理的研究，EI是工程类的，侧重技术的实用性。两者级别差不多，但是就重要性来说sci重要性高一些。
香港理工大学（英语：The Hong Kong Polytechnic University；缩写：PolyU或HKPU），是一所坐落于香港九龙红磡湾的公立应用研究型大学。香港城市大学（City University of Hong Kong），简称城大（CityU），是一所坐落于香港九龙塘的公立研究型大学。在土木工程专业上，香港理工大学在中国排名第二，仅次于清华大学。就这个专业来看，香港理工大学要比香港城市大学好一些。土木工程在香港理工大学是比较热门的专业而且就业前景也是相当不错的。
理工好像好一点吧 城大主要是survey
四区的SCI
不是sci的行不行，我投过土木工程
知道几个，但英文不会写。

牛呀，被SCI检索，还有影响因子的要求！
可以利用web of science检索土木工程类的SCI期刊～
