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.

Physiologicalmechanism of high yielding corn in the ravined valley was studied. Based on the results,the technical regime of ecologically adverse resistant and high yielding cultivation forthe corn in the ravined gully has been constructed. The major detailed techniques for theregime are ridging-ploughing in autumn and film-mulching during the thawing time inspring, adopting compact corn varieties with big ears and grains and adequately longgrowing stage, fertilizing adequately at seedtime and at jointing stage and irrigatingwith floodwater in the middle and late. The standardized techniques have also beenestablished.
