The preparation of X-zeolite powder was investigatedin hydrothermal system, the crystal growth process of X-zeolite in hydrothermal condition was characterized
An analytical expression for the prediction of shear-compressive fracture process zone(SCFPZ) is derived by using a proposed local strain energy density criteri
Based on principal component analysis, a multiple neural network was proposed. The principal component analysis was firstly used to reorganize the input variabl
