Then simulate and analyze the variation of ground temperature rise at well bore with long-term intermittent operation for the system and the influence of different well spacing,ground and backfill materials thermal conductivity,well depth on the outlet temperature and the ground temperature rise at well bore.
No. 1 buried coil adopts vertical buried pipe, its material is PPR tube which diameter is 25mm, the average drilling depth is 35m; No.2 buried coil is also adopts vertical buried pipe used the same material, its average drilling depth is 30m; When refrigerating with the soil heat exchanger, opening heat pump group, cooling pump and cooling water pump.
So, it should select suitable backfill material according to geological features in practical engineering to achieve the least drilling quantity under same load,then reduce the initial investment.

It also integrates the mechanical, electronic, material, chemical and information technology.
Aircraft manufacturers use nesting/pre-cut technology to increase the utility of raw material.
Then the formal shop order will release to the stock area to pull the raw material out.
Queue level control: Production controllers dispatch materials into work center base on the MRP requirement and work-in-process level.

Material model and parameter. 1) Use *MAT_CONCRETE_DAMAGE_ REL3 model as the concrete material in LS-DYNA.
When analysis, hypothesis rupture of concrete material is overlooked, so there is no concrete element destroy in computed results of RC column.
Actually, concrete material has been ruptured early.

This type of measurement method has high measurement precision and resolution which is especially suitable for some soft material workpiece.
The method is especially suitable for measuring optical surface and plating surface, which are made of soft material.
It is particularly applicable to some soft material, plastic material and biological material.
For some workpieces made of soft material, plastics, glass and so on, the workpiece surface is scratched, more or less, by the stylus of the machine.

This implied that urea groups is more stable than urethane groups, and with the increasing content of DMPA, additional urethane and urea groups would be formed in polyurethane chain, which caused lower thermal stability of WPU materials.

In order to identify damage using AU a signal needs to be sent through the material prior to the damage, which is commonly known as a baseline [6].
Then once the baseline has been logged the material can go into its intended service.
Eight layers of the material were used to manufacture a large single patch and the material was vacuum bagged and cured in an autoclave in line with the manufacturers guidelines at 120 ºC for one hour.

The input parameters of the finite element model are provided as random variables to account for uncertainty in the material, geometry, and loading parameters.
The fiber cross-sections are composed of uniaxial material models.
Material models for steel, unconfined concrete in girders and column cover regions and confined concrete in column core regions that are used in the actual work correspond respectively to the uniaxial smoothed bi-linear steel material and uniaxial smoothed concrete material.
The material properties of the concrete and reinforcement steel and load parameters are modelled as aleatory random variables, as detailed in Table 2, Figure 5, Figure 6 and Figure 7.
