This paper discussed the relationship between the SBP reference value of the health Adolescent boys and the geographical factors in china. There are different SBP reference value in different areas of china, and we chose...
According to the particularity of cold-region for its geographical and climatic environments where the oil-pipeline is laid, the author adopts suitably physical parameters and mathematical-physical models involved in the oil-pipeline system, to simulate the boundary conditions of ground surfaces and the region where oil-pipeline is located, constructing finite element (FE) analysis models of the coupled...
As a functional material of the enhanced cooling, porous matrix has been widely used in the environments concerned with very high temperature. Through the pores of the porous matrix, the flowing coolant absorbs and takes away the heat inside the matrix to achieve the thermal protection of high temperature structures. In the past investigations on the permeability of porous materials, experiments and...
