accretion
n. 堆积; <植>连生; 添加生长; <天>吸积
An accretion is an addition to something, usually one that has been added over a period of time.
The script has been gathering editorial accretions for years.
多年来该剧本一直在修改。
Accretion is the process of new layers or parts being added to something so that it increases in size.
A coral reef is built by the accretion of tiny, identical organisms.
珊瑚礁是由许多相同的微生物不断堆积而成。
1. an increase by natural growth or addition
2. something contributing to growth or increase;
3. (astronomy) the formation of a celestial object by the effect of gravity pulling together surrounding objects and gases
4. (biology) growth by addition as by the adhesion of parts or particles
5. (geology) an increase in land resulting from alluvial deposits or water-borne sediment
6. (law) an increase in a beneficiary's share in an estate (as when a co-beneficiary dies or fails to meet some condition or rejects the inheritance)
The accretion phenomenon was firstly discussed by Kelvin et al. on the 19 th.
十九世纪末,开尔文(Kelvin)等人首先讨论了吸积现象.
The planetesimals accretions of the Earth obviously have two stages, including initial accretion and late accretion.
这种不均一性起源于前地球阶段堆积星子的不均一性.
It is well known that accretion disks are hydrodynamic disks with anomalous viscosity.
天体物理吸积盘是具有反常粘滞的流体盘.
Nevertheless, astrophysicists have persisted in their belief that accretion disks are indeed turbulent.
虽然如此, 天文物理学家仍旧坚持信念,认为吸积盘的确是充满乱流扰动的.
An accretion disk with vertical structure is studied by using a new anomalous viscosity.
利用一种全新的反常粘滞,主要研究了具有垂向结构的吸积盘.
