FCC结构的镍原子半径为0.1243 nm,试求镍的晶格参数和密度。Radius of Ni atom in FCC structure is 0.1243 nm, please calculate the lattice parameter and density of Ni.相关知识点: 试题来源: 解析 答:FCC为面心立方结构,其中 已知R=0.1243 nm 则a= 0.3516 nm 镍的晶格参数为a=b=c=0.3516 nm a = ...
In this case, 𝛿δ (in Equation (17)) is the non-dimensional ratio of the radius of the particle orbit in the cyclone to the radius at the exit (i.e., 𝑟𝑟0rr0). Without much loss of accuracy, the workers [163] found that: 𝛿=(2𝜋𝑆𝑡𝐵2)12𝛼δ=2πStB212α...
