Anthropologists wondered where the remote ancestors of the polyesian peoples now living in the pacific islands came from . 人类学家极想知道现今生活在太平洋群岛上的波利尼亚各族人的远祖是从哪里迁来的。
The discontinuous component of the genetic variation pattern of a species also contains the differences among subpopulations resulting from accidents of sampling genetic drift and others . 物种遗传变异型不连续的成分也包含抽样遗传播迁和其他事故引起的亚种群之间的差别。
An atom on an excited upper level can execute a downward transition not just spontaneously but also when photons of the radiation field surrounding the atomic interact with it . 处在较高的激发态上的原子不只可以自发地而且可以在它与原子系统周围辐射场的光子相互作用时发生向下的跃迁。
The absorption of this radiation in various lines followed by cascade transitions to lower levels might ultimately produce an anomalously high population for the excited levels of these molecules . 在各谱线处对这种辐射的吸收以及接着向低能级的级联跃迁最终可能使这些分子的激发能级产生异常高的粒子数。
