For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.

Cao Guowei: The atmosphere that is brought up in one's childhood, actually I also am born in the Great Cultural Revolution, so we what doesn't the person that that time is born have actually too much the atmosphere that be in business, should for Shanghai whole environment is opposite China elsewhere for, I feel commercial breath or the commercial consciousness of people is stronger, this may have bit of effect, but I feel very much or the environment in grown the following very much education, job, can my whole business side the sort of no matter be recognizant it may not be a bad idea, experience it may not be a bad idea, can edify come out, be in especially sina I feel on this platform is very big to my help.

曹国伟：小时候长大的氛围，其实我也是在文化大革命出生的，所以我们那个年代出生的人其实并没有什么太多经商的氛围，应该来说上海整个环境相对中国其它地方来说，我觉得商业气息或者人们的商业意识是比较强的，这可能有点影响，但我觉得很多还是在长大以后的很多教育、工作的环境，能够把我整个的商业方面那种不管是意识也好、经验也好，能够熏陶出来，尤其在新浪这个平台上我觉得对我的帮助是非常大的。
