The the Qitaihe downtown area overall relocation, relocation Hengshan district, Jixi City, a small part of the residential area, causing a lot of wasting of human and material resources.
For example, Qitaihe City in nearly 10 years of governance collapse practice, starting from the investment in science and technology, and increased the governance collapse research efforts, achieved good social and economic benefits.
Heilongjiang coal cities has entered depletion period, but its advantages in resources persists, the prerequisite for the use of coal cost is relatively low to extend its industrial chain engineering, for example, from coal, materials, coking coal, metalworking, chemical coal deep-processing and finishing the conversion of resources and enhance the economic value of the product to promote coal production, business, pin-round development, and thus find the resources the citysustainable development.

The essential problem in welding of thick materials is to obtain the proper penetration in the whole cross section of welded joint.
Typical way of welding thick materials is multipass welding process -laying of many joints step by step.
Generally, its originality consists in using plasma arc for preheating of materials.

During any season, though dominated by microbial action, the rate of CO2 decomposition of organic materials is also high and contributes to increased CO2 emissions.

Applications of Specific Forms in Modelling Design of Industrial Product Shape is mainly refers to outside basic shape of the product that corresponds to the contents or materials, and have characteristics of generalization and abstract.
Because, compared to rectangle, it is Specific forms and has strong contrast of quadrate and roundness, so on the modelling by combining different rectangles the huge disc is very outstanding which not only constructs the aesthetic characteristics of product modeling, but also strengthen the sense of science and technology of the machine tool.
The characteristics of square geometry totally different from ripple shape existing in the same continuous shape that reflects not only the continuation of same material but also the continuation of same shape .We can't split the shape into two separate parts，because they are in fact in a material entity that has the shape with some different local shapes.
