在低空位浓度的晶体中，由空位机制引起的原子运动是由特定原子和特定空位相遇引起的原子跳跃序列中的相关行走。结果表明，原子在立方晶体中相关游动的扩散相关因子和原子位移概率可以由随机游动理论的一些已知函数简单求得。
At low vacancy concentrations in crystals the motion of an atom due to the vacancy mechanism is a correlated walk during the sequence of atomic jumps arising from an encounter of a specific atom and a specific vacancy. It is shown that the diffusion correlation factor and the atomic displacement probability of the correlated walk of an atom in a cubic crystal may be simply obtained from some well known functions of random walk theory.
