分离量 meaning in English

fractional dose

The numerical results show that the appearance of focal switch rests not only on the distance of aperture and lens but also on truncation parameter ; focal switch possibly occurs only when truncation parameter is between its critical maximum and minimum truncation parameters
数值结果表明：焦开关的出现不仅与光阑透镜分离量有关，还与截断参数值密切相关；仅当截断参数取某一上、下限之间的值时，才可能出现焦开关。
Then the computational results are compared with the experimental data including stress , strain , temperature , bolt force and separation , which are obtained by the china nuclear power operation research institute ( wuhan ) and china nuclear power academy design research institute . either under cooling or heating cycle , no matter the qualitative regularity or quantitative data , the computational results are in common with the experimental data
所得计算结果与中国核动力运行研究所（武汉）和中国核动力院设计研究所在压力容器模拟体上所测的大量应力、应变、温度、螺栓力、分离量等数据进行了对比，在两种载荷工况下，无论是冷态还是热态，无论是定性规律还是定量数据，分析结果和实验结果都吻合良好。
