Formation thermo physical properties are the key to the Ground source heat pump system design, which include thermal conductivity, soil thermal diffusivity and so on.
In the design of ground source heat pump, thermal conductivity λ is the most important factor. λ is the material properties of rock and soil, it relate to density, temperature, particle shape, porosity, moisture content and soil composition.
Rb value depends to some extent involved in the borehole itself and the thermal properties of materials, so it can be determined by in situ thermal response test.

Though a series of modified Z-A model were developed, such as Samantaray’s [11] model, the underlying physical process and the composition of the material components are not considered.
The various obstacles in the material have a contribution to the dislocation mean free path of slip, thus, the dislocation mean free path which combined the distance between the second-phase particles, the distance between the grain size and the distance to other dislocation is given by Engberg [18]

Obviously, the material capability of the turbine blades limits this temperature.
Therefore improvements in creep strength through material development as well as single-crystalline casting and application of thermal barrier coatings increase the turbine efficiency [3].

The experiment adopts this process to deal with the oil pollutant of car washing wastewater, in order to reduce the oil content of waste water, and provide prerequisites for the recycling of car washing wastewater. 1 Experiment 1.1 The experimental water quality The experimental water is using the wastewater from a car wash of the Shenyang Hunnan New Area ,the car wash put wastewater into the collecting tank after clean vehicles, the key water quality parameters of raw water are shown in Table 1.
Therefore, before the experiment , the raw water should do pretreatment, Pretreatment is that making the raw water statically precipitate 6 hours and taking out supernate, at this time the turbidity of the supernatant is 27 NTU ~ 63 NTU. 1.2 Materials and instruments Petroleum ether, analytically pure; Poly Aluminum Ferric Chloride (PAFC); polyacrylamide(PAM); 752PC-type UV spectrophotometer, hollow fiber membrane module. 1.3The experiment device Figure 1 Experiment device flowchart Description: 1 - inlet water tank; 2 - self-priming pump; 3 - flowmeter;4 - flotation column; 5- gas-liquid mixing pump; 6 - dissolved air vessel; 7 - outgassing vent; 8- fiber membrane module;9- peristaltic pump; 10 - outlet water tank; 11 - outlet; 12 - sampling ports; 13 - trash mouth.
Oil pollutants in the wastewater belong to hydrophobic substances, under the effect of micro-bubbles and surfactants, oil material can be combined with air bubbles reach to the top of the flotation column along with the flow and be cleared.
It is more sophisticated than the ordinary filtration process by screening the flowing material from the microscopic point of view, therefore, it can effectively separate the pollutants in order to further improve the oil revoming rate.

Index as a result of the theoretical model The “raw material” for the measurements in question, may embrace rather wide circle of “mental elements,” including various kinds of knowledge and/or opinions (about everyday life, politics, science, art, literature, etc.), numerous feelings while perception, different creative abilities, and so forth (see, e.g., [3-6]).
In other words, the “raw material” may include all elements which relate to the sphere of “cultural wealth” of personality.
