The nucellus is usually degraded and absorbed as the endosperm develops . 珠心通常在胚乳发育时被分解和吸收。
These interactions are of two main types, namely, scattering and absorption . 在这些相互作用中,主要有两种类型,即散射作用和吸收作用。
Blackbody radiation always is the result of a succession of emission and absorption processes . 黑体辐射总是一系列发射和吸收过程的综合结果。
The degradation or assimilation of fatty materials is often restricted because of their relative insolubility . 脂肪物质因其溶解度低,分解作用和吸收作用常受限制。
It is assumed that the emission and absorption of light energy by an atom or molecule is not a continuous process but occurs in steps . 假定原子或分子发射光能和吸收光只能不是一个连续的过程,而是阶梯式发生的。
