Different abrasive particle material has different density, as is listed in Table 1.
As different abrasive particle material has different difficult level for different enterprises to obtain, it's necessary to choose a suitable abrasive particle material to guarantee enough impact force and reduce the cost.
Suitable abrasive particle size, concentration and the material could guarantee enough impact force and reduce the cost.

Shear wall exceeds the limits of the necessary, however, is not the economy, shear wall is too much, although there is a strong seismic ability, but because the stiffness is too big, cycle is too short, the earthquake is increased, not only increase the upper material, also bring difficulty to the foundation design, have a certain ability to resist side other framework, to determine the reasonable number of shear wall is particularly important for structure optimization design.
Elastic-plastic time history analysis method analysis steps Time-history analysis of the structure, generally can be divided into the following steps: (1)According to the building of site conditions, factors such as intensity, selecting several typical earthquake acceleration time-history curve with different characteristics, as the design of seismic wave input; (2)According to the mechanics characteristics of structure system, establish reasonable structure vibration model; (3)According to the material properties, structure type and condition, choosing the proper structure of restoring force model, and determine the structure of the corresponding to (or components) of cracking, yielding and ultimate displacement restoring force characteristic parameters of feature points, and the restoring force characteristic curve of each line segment stiffness value; (4)Establishing a structure under the action of earthquake vibration differential equations; (5)Using the step-by-step integration

Review of soil temperature recovery characteristics of the GSHP system Didi Xue1, a, Xin Wang1, b and Zhiwen Cheng1, c 1College of Environmental Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China.
Shang Yan et. al [2] established a three-dimensional non- steady-state heat transfer model based on seepage of underground vertical U -shaped pipe and the surrounding wet soil heat transfer coupling numerical calculations to simulate the heat pump running soil temperature changes and temperature heat pump stop state soil temperature recovery characteristics; numerical analysis results showed that soil thermal conductivity, soil porosity, different backfill materials and solar radiation on the ground temperature affects both the recovery process.
Soil thermal conductivity, porosity and backfill materials all have a great influence on the soil temperature recovery.
