The surface of separation between the very hot core and the somewhat cooler outer layer is the radiation front . 十分热的芯部和略为冷些的外区之间的分界层就叫做辐射波阵面。
When the separation of the molecules is large, as in a gas, the force is extremely small and attractive . 分子间的距离较大时，如在气体中，分子间的作用力极为微小，而且是引力。
The first task in separation of subcellular components is always the rupturing of the cell wall and the protoplasmic membranes . 分离亚细胞组成的第一步总是使细胞壁和原生质膜破碎。
In the limit, for very weak rock, settlement at the boundary can also occur before the separation crack . 在极限情况下，对于非常软弱的岩石，形成分离裂缝之前，也会发生边界处的沉陷。
Usually, it also causes the wall heat transfer rate to decrease somewhat in the region downstream from the point of separation . 通常，它也会使分离点下游区间内的壁热交换率有所减少。
The general objective of distillation is the separation of substances that have different vapor pressures at any given temperature . 蒸馏的一般目的，是分离在任何给定温度下具有不同蒸汽压的诸物质。
The validity of the centralfield approximation rests on the great mass of the sun and on the relatively great separation of the planets . 中心场近似的准确性基于太阳的巨大质量以及行星之间的巨大距离。
This separation step is rather lengthy and cannot always be achieved, due to a high residual content of pyrite in the kerogen . 由于油母质中黄铁矿的剩余含量较高，这个分离过程相当长，而且总是不能达到。
When the whole melting was complete it was held in abeyance for a few minutes to facilitate the separation of foreign substances . 铸铁完全熔化了，他们让它在承受器停留一会儿，使铁汁里的杂质容易被隔离开来。
Other control measurements are normally made across the joints or at the base of the principal cantilever to determine the eventual separation movements . 通常沿着各条接缝或主悬臂梁的基底作其它控制测量，以确定最后的分离运动。
