perform a good balance in mechanical properties, including high strength at high temperature (>1000℃) and reasonably high fracture toughness at room temperature. Metastable phase Nb3Si plays......
RESEARCH ON EROSION OF SILICON CARBIDECERAMIC BLADE陈家炎Wuhan University of Technology摘 要:<正> In this paper, three linds of silicon carbide ceramic materials are chosen to perform the tests of material erosive wear. The relationship of ambient parameters, abrasive property and target property is studied in these experiments. Some main factors......

:The study of earth masses requires numerical methods that provide the quantification of the safety factor without requiring detrimental assumptions. For that, equilibrium analysis can perform fast.... It is compared with a published case and used to perform probabilistic studies in both a homogeneous and a layered foundation. Analyses show that the shape of the density probability functions is highly......
to perform numerical simulations more quickly. In the least square inversion, the conjugate gradient method was adopted to avoid calculating sensitivity matrix completely, which greatly decreases the time and memory space needed to do 3-D inversions. Then, it is practical to perform monitoring resistivity data inversion effectively to satisfy the requirements of engineering. Synthetic data was used......
