Ultrasonic Inspection of Small Inclusion(SI) in Powder Metallurgy Materials 粉末材料中微夹杂缺陷的超声波检验
The ductile fracture initiation toughness of material C with high content and larger size of inclusion will be less than that of the material B with low content and small size of inclusion. 夹杂物含量较高,尺寸较大的材料C的延性起裂韧性Pi/Pgy低于夹杂物量少,尺寸小的材料B。
This paper described in detail three methods & finite element, small parameter and elliptical inclusion methods, which are sed to compute the effect of the dilatancy on tidal tilt and strain. 本文讨论了用于计算扩容对潮汐倾斜和应变影响的三种方法&有限单元法、小参数法、椭圆包体法。
The interaction mechanism of the small organic molecules and the inclusion compound of naphthol / β - CD can be interpreted by the formation of hydrogen bond and solvent effect. 有机小分子与萘酚/βCD包合物的作用机理可从形成氢键和溶剂效应得到合理的解释。
Significance and application of reconnaissance run with a small amount of sample for preparatory technique in isotope research of fluid inclusion 流体包裹体同位素小样量先行试验制样方法的意义及应用
