The diameter of the nucleus, if we think of it as roughly spherical, is of the order of 10－14m . 如把原子核粗略地看作球形，则它的直径的数量级为1014m。
The packing of spherical atoms of ions is one of the most fundamental structural patterns of nature . 球形原子或离子的堆积是自然界中一种最基本的结构模式。
In a spherical nucleus, the coupling term implies an interweaving of the quadrupole and dipole motion . 对球形核中的耦合项意味着四级运动和偶极运动间的交织。
This figure shows four stages in the outward motion of the spherical blast originating from an air burst . 图中表明空中爆炸时发生的球形爆震波向外移动的四个阶段。
Only discrete wavelengths of matter waves may resonate within the spherical volume of a hydrogen atom . 物质波在一个氢原子的球形体积内也只有一定的分立波才能发生共振。
The rest was chiefly periwigs, wearing-linen, razors, washballs, perfumes, and other useful things . 其余的多半是假发，衣服，剃刀，球形肥皂，香水以及其他一些有用的东西。
The changes in force application as a spherical particle moves up into the airstream are shown in fig. 2. 123 . 当一个球形的颗粒在气流中向上移动时，其作用力的改变如图2-123所示。
These have been developed by the numerical integration of the differential equations of gas motion for a spherical blast wave in air . 这些都是根据空中球形爆震波气体运动的微分方程的数值积分得到的。
The spherical particles are swept as droplets or volatilized and recondensed from a meteorite as it is heated to incandescence by friction in the upper atmosphere . 球形粒子是由小滴吹刮或者由在高层大气中被摩擦加热到白炽化的陨石挥发并重新凝结而成。
