Perturbation calculation will be required to rapidly determine the changes of reactivity caused by core neutron cross sections perturbation in reactor physics design and analysis.

在反应堆物理设计和分析时，经常要进行微扰计算，以快速分析堆芯中子截面扰动下反应性的变化量。

For example, any violation of the expected symmetry between hydrogen and antihydrogen would rock physics to its core.

例如，任何违反氢和反氢之间对称的期望会动摇物理学的核心。
