Through a complete cycle of raising interest rates after this week lowered interest rates for the first time, but for the time being due to the abolition of tax on bank deposits, the bank's depositors did not reduce the number of receipts, before the rate cut The one-year deposit rate of return on investment for 3.933 percent, to cut interest rates after an investment return of 3.87 percent, and 10,000 yuan a year-to-deposit interest rate reduction of only 6.30 yuan, so that the bank will cut interest rates failed to exercise any time In the stock market to the role, it may not bring immediate relief to stimulate consumption, the rentier will still be money in the bank to ease food profits.

降低首次利率，但暂时由于税银行存款，银行的存款并没有减少多少收益取消前降息的一年为3.933的百分之投资回报期存款利率，削减后的投资回报百分之3.87的利率，并万元一年来，存款利息只有6.30元，率降低，使央行将降息未能行使任何在股票市场的作用的时候，却未必会即时援助，以刺激消费，食利者仍将在银行存款，以解决粮食利润。

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.

Microscopic characteristics of cladded crystal fiber are analyzed by X-ray diffraction, Laue X-ray diffraction and scanning electron microscopy, it is found that magnesium-ion indiffusion does not affect the single crystal structure and the domain structure of the magnesium diffused crystal fiber. It is found for the first time that MgO-rich layer in the magnesium diffused LiNbO〓 surface layer exhibits the crystal structure of an unknown compound from the Li-Mg-Nb-O ternary system and MgNb〓O〓. It is proposed for the first time that this unknown compound and MgNb〓O〓 in MgO-rich layer are the real sources of magnesium-ion indiffusion LiNbO〓. Their appearance indicate that MgNb〓O〓 is in the surface layer of MgO-rich layer, the unknown compound is in the subsurface layer and beneath where the MgNb〓O〓 is located, and these compounds have obviously preferred orientation.
