Research On Correlation Between Surface Temperature And Nearby Air Temperature Of The Underlay Xu Yuan1, a, Qiong Li2,b and Qinglin Meng3,c 1, 2, 3Building Environment and Energy Laboratory, State Key Laboratory of Subtropical Building Science, South China University of Technology, Guangzhou, 510640, China axuxuwill@163.com, barliqiong@scut.edu.cn Keywords: underlay surface temperature, air temperature 1.5m high, correlation Abstract.
First of all, reflectivity is different, which makes the receiving of the solar radiation different; also the energy exchange and the material between the surface and the atmosphere (mainly water vapor and carbon dioxide) depend on the nature of the underlay.[3]These factors will affect the air temperature directly or indirectly.

The empirical formula provided by Tait is usually used to express the relationship among P-V-T during pressure maintain process: ; ;; Where Tg is the glass transition temperature ( for nonlinear materials ) or the crystallization temperature (for crystalline materials).
In the above equations, b1,1~b9 are material constants.
When establishing the mathematical model of temperature field in the process of cooling, simplifying should be done as follows: Ignores the gap thermal resistance between cavity with plastic melt, and takes heat-conducting properties of the mould materials as isotropic.

In order to quantify the resource consumption, in this study the demand of raw materials and operating materials of the selective laser melting process was quantified according to the methodology developed within the initiative Cooperative Effort on Process Emissions in Manufacturing (CO2PE!).
First, fewer material waste is created in additive processes compared to chipping processes.
In addition to technical gases, the recyclable share of the material powder was measured by using a scale.

And these element material parameters are set to the real material parameters and only their topological variables are set to ),2,1( 1 L=jt jm at the first iteration step after applying the operations of Eq. (6) .
The modified values of fjqC , qa and qb for all real material elements are substituted into Eq.(10).
