As the discrepancy between the development speeds of the two systems became smaller, the coupling degree was closer to 45°, and the two systems were becoming better coordinated.[5]
The cause analysis of environment and resources problems
Shenyang metropolitan area is the heavy chemical industry concentrated area, is the important equipment manufacturing industry and raw materials production base, and is one of the worst environmental pollution areas.

Abstract
Based on the theory of cantilever construction, combined with a three cross continuous rigid frame bridge, choosing the biggest cantilever stage, side span cross fold stages, middle span cross fold stage and complete bridge stage as the research object.
Here, the bridge is a general one, and (damp ratio) of reinforce concrete structure is 0.05. 2.2 Restoring force model of material Three linear stiffness degradation is used to make non-liner computing, and restoring force model of material is shown in Fig 1.

Under the hinterland of the Junggar Basin in the thick Cenozoic sedimentary developed more the consecutive complete the late Paleozoic strata, these strata contain clastic sedimentary rocks, and also contains part of the magmatic rocks, to explore the basement nature of the Junggar basin, basin hinterland late Paleozoic source district changes and the corresponding tectonic evolution provides the ideal material.
Laser ablation-multicollector plasma mass spectrometry (LA-MC-ICPMS) can also be in situ determination of zircon Hf isotope compositions provide unique constraints for zircon Hf source (such as a depleted mantle and evolution of the earth's crust), zirconium stone of Ti thermometer to determine the temperature of formation of zircon, zircon oxygen isotopes to determine whether the zircon from recycled crustal material.

Introduction
At present, the general area, buildings, schools, industrial and mining enterprises generally realized the water, electricity, gas, heat divided metering mode, table are mostly located in the house, the general need special meter reading personnel into people's homes, this way to the residents of inconvenience and interference greatly, even has the security hidden danger, in terms of management, there are low efficiency, manpower and material resources, human factors, management and many other issues.
The system can also provide the function of remote control, remote control water valve and an electric circuit switching, this method greatly improves the management means and management power, the meter reading system not only to meet the data copy, better management, in payment arrears, overload, cut off cut off time period so as to realize more supply powerful functions, improve the level of the management, saving manpower and material resources.

Watson [3] also suggested that from the past investigations and researches, directly or indirectly, accidents basically can be caused by three aspects, which are either people itself, materials or equipment or by the combination of these aspects.
