Abstract: After years of research about the geothermal resources in the northern part of Songliao Basin, preliminary results have been achieved in the exploration and development of middle-shallow layer geothermal resources and oilfield production water geothermal resources.
Meanwhile, the deep fracture deeply cut earth crust, become weak belt, and become the rising channel of mantle material and the heat flow, create good conditions for the base hack, intrusion, convection of magma and formation of Hot Dry Rock, while the deep fracture controls volcanic activity of the basin and the basin basement, and make up the fracture net connected the upper mantle heat source together with fracture in basin.

Because of the low speed early, which of the passenger train is less than 120km/h and the freight train is not ruled in design code with the operating speed of 60km/h, the bridge were designed to fulfill the requirement of ultimate capacity and save material.

Intoduction
It is well known that amplitude-dependent internal friction (ADIF) in crystals is created by the
interaction between dislocations and point defects (PD).
The ADIF is approximately equal to the YMD, though their ratio differs from l , and is given by a power function of the strain amplitude: n h Aεδ = . (9) Here n is a numeral factor typical for the specific material and depends on postdeformation aging, impurity content and dose of X-ray irradiation, but not on temperature.

The chemical industry with coal as raw material is called coal chemical industry and it can be classified into traditional coal chemical industry and advanced coal chemical industry.Traditional coal chemical industry means the industry with long history and mature technology such as coal coking,methanol from coal and calcium carbide from coal and advanced coal chemical industry refers to the industry directed by coal-based alternate energy such as converting coal into oil,olefin,dimethyl ether,natural gas and glycol.Traditional coal chemical industry in China develop with a extensive development mode which lead to a serious of problems : great resource and energy wastage with heavy environment load,similar product structure with many primary products and low deep -processing product,obvious surplus production with a high proportion of less competitive product and a low rate of operation,for instance,In 2008,the coke production utilization rate in China is about 75 percent,calcium carbide
In the meantime,our dependence on imported oil is increasing year by year.In 2009 China imported 2.04 tons of crude oil and the crude oil external dependence reach 52.6 percent.With the acceleration of industrialization process,the shortage of oil have seriously restricts the economic development of our country.Facing the serious lack of oil all over the world,the energy security prollem of China is becoming increasingly acute.It is significant for the strategy of oil substitute to develop the advanced coal chemical industry energetically,especially coal-based substitute solution such as coal liquifaction,coal to olefin ,etc As important fuel and chemical materials,coal plays an important role in the development of our national economy.But,about 50 percent of coal in China is used to generate electricity by direct combustion in thermal power industry The coal utilization efficiency of this primary manner is very low which not only caused such a waste in resorce but also spoiled the ecological
By referring to plenty of material, gas production of China in 1995-2012 can be obtained which are used as original data x(0) and GM (1,1) model is used to predict gas production of China in the future.

Because Granier probe to the variation of the temperature is anomaly sensitive, the probes were external packaged radiation material to reduce the thermal radiation to probe the interference, at the same time it can prevent rain immersion effect to guarantee the determination results from the influence of a certain extent.
