急求毕业论文摘要翻译成英文！！！！100+金币啊
手性有机小分子催化因其特有的优点，在最近数年间，得到了众多化学工作者的关注。在众多手性小分子催化剂中，伯胺硫脲催化剂在不同系列反应中被广泛应用。本文以廉价、易得的异斯特维醇为起始原料，对其进行结构改造，在4位碳上分别引入伯胺硫脲结构基团和叔胺硫脲结构基团，最终得到了4种结构不同的伯胺硫脲催化剂和4种结构不同的叔胺硫脲催化剂。
我们以异斯特维醇衍生的手性伯胺硫脲为催化剂，催化N-苯基马来酰亚胺和异丁醛的不对称Michael加成反应。经过对不同反应条件的筛选，最终确定了最佳反应条件：以甲苯作溶剂，1.0mol%的催化剂，室温条件，N-苯基马来酰亚胺和异丁醛的投料比是1:2。然后在最优条件下，我们又对底物的普适性进行研究考察，可得到令人满意的催化效果：58-96%的催化收率和60-99%的对映选择性。最后我们又考察了在放大反应底物的量的情况的催化效果，同样能够得到理想的效果。
内容太专业了！建议楼主自行搜索相关中文文献，只看中英文摘要，基本就能搞定；再看看英文文章的摘要加以润色即可！不会用太长时间的，到时前提是英语基础不要太差。 又到了毕业季，桑不起啊 内容上倒是其次，太花时间，而且别人翻译的东西你放心吗？自己用点心吧 Chiral catalysis of organic small molecules because of its unique advantages, in the recent few years, got the attention of many chemists . Among the chiral catalyst is a small molecule , a primary amine thiourea series reaction catalyst type is widely used . In this paper, cheap , easy to get iso Site Wei alcohol as the starting material , its structural transformation , respectively, at 4 carbon structure introduced primary amine thiourea thiourea groups and tertiary structure of the group and eventually got 4 a primary amine with different structures and four kinds of thiourea catalysts different tertiary structures thiourea catalyst.
Chiral primary amine thiourea we iso斯特维alcohol derived asymmetric Michael addition catalyst , the catalytic N- phenylmaleimide and isobutyraldehyde reaction .

请求毕业论文摘要的英文翻译，（不要百度在线翻译贴过来的。）
毕竟论文是书面的东西。员工流失现已成为酒店业发展过程中最主要的问题之一，酒店业也随之蓬勃发展起来，不要口语化的。再次谢谢，只要能把意思翻译出来就行！还有就是不要百度在线翻译复制粘贴过来的、领导管理层管理理念落后等原因并提出解决对策。但不能漏句哦。以下是翻译的内容，那个我也会，指出该酒店在留人问题上出现的酒店地理位置偏僻：随着经济的发展，但是我不相信在线翻译，要书面语！会给加分的、招聘体制和培训机制不健全。顺便再给翻译一下论文题目，中式英语伤不起。本课题将针对北京乔波会议中心酒店的员工流失问题进行分析、薪酬福利缺乏对外竞争力，为企业管理人员在员工流失问题方面提供决策参考谢谢专业英语人士给我翻译下，对整个企业的影响决不可小视。句子翻译不用特别精炼

花钱没有人会水平那么高给你无偿翻译的。有下班时间的，比如有道翻译，有专门翻译论文的，去网上在线付费翻译吧
自己已经翻译好了！没抱大希望！不是有这个平台侥幸问问
果然都不是活雷锋！
呵呵你是活雷锋倒好
