理论预测的位移的原子位移速率的变化与空洞生长的温度制度进行了研究。首先回顾了膨胀率作为温度和剂量率的函数的一般关系。在此基础上，导出了温度漂移随剂量率变化的简单显式表达式。这些表达式中的每一个都适用于空隙生长的不同限制机制，这是由点缺陷损失的主导过程决定的--也就是说，无论是通过基质中的相互复合还是通过汇处的吸收，以及通过点缺陷吸收的模式在空隙处，即，无论是表面反应还是扩散控制。这些表达式的差异的物理基础进行了描述。这方面的信息的一个紧凑的摘要。
The theoretically predicted shift in the temperature regime of void growth with changes in atomic displacement rate is investigated. The general relations from which the swelling rate may be calculated as a function of temperature and dose rate are first recalled. Based on these, simpler explicit expressions for temperature shift with dose rate are derived. Each of these expressions applies in a different limiting regime of void growth, which is determined by the dominant process of point defect loss — that is, whether by mutual recombination in the matrix or by absorption at sinks, and by the mode of point defect absorption at voids, i.e., whether surface reaction or diffusion controlled. The physical bases of differences in these expressions are described. A compact summary of this information is presented.
