, CeO2/SiO2 loadings and Si/Ce molar ratio on the granular catalysts for NO selective catalytic reduction with ammonia (NH3-SCR) were studied. Results indicated that both CeO2/SiO2/ATS and CeO2/ATS......
,在实际过程中难以准确得到吸附层厚度,致使模型采用的固相体积分数与有效固相体积分数存在偏差[15]. 图3 采用2种流变模型拟合得到的浆料黏度随固相体积分数变化曲线 Fig. 3 Fitted curves of viscosities with solid loadings of ZrO2 suspensions using flow models 表2 German和Krieger......
graded materials layer for plane problem under dynamic loadings, a stochastic model is established for plane problem in which the material properties of the functionally graded materials layer vary randomly in the thickness direction, and the crack is parallel to the materials faces. A pair of dynamic loadings applied on the crack faces are treated as stationary stochastic processes of time......
zone and matrix zone. Twinning was considered as the dominant plastic deformation mechanism of depleted uranium subjected to impact loadings. Besides twinning, the dislocation slipping also played... and good self-sharpening property [1]. Broad applications in military fields, DU would be suffered from the impact loadings or shock loadings inevitably. Thus, it is necessary to obtain a fundamental......
of isotropic rock masses around a deep spherical tunnel, a new mechanical model subjected to dynamic unloading under hydrostatic pressure condition is proposed. The total elastic stress-field distributions......

and by sintering at(590±10)°C for 3 h.Cold upset forging tests were carried out,the true axial stress(σz),the true hoop stress(σ?),and the true hydrostatic stress(σm)were evaluated and,their behavior against......
principle was proposed to calculate the stability coefficient of the sub-slope masses. The influencing factors such as sloping angle, water content, hydrostatic pressure, seismic force as well......
, 100, 200, and 1000. The present work also comprised the investigation of the density and microstructure of Mg-25Al-15Zn-14 Cu alloy before and after thermal cycles by using the hydrostatic method......
oxygen content of deep sea, resulting in an unstable and vulnerable film. Pitting depth was most influenced by hydrostatic pressure, which can increase the adsorption and penetration of Cl-ion......
