查询词典 accretion

Black hole mass, along with the ratio of the accretionrate to the Eddington accretion rate, is a fundamental parameter of active galactic nuclei.

与吸积率和爱丁顿吸积率的比率一道，黑洞质量也是活动星系核的一个基本参数。

At the same time, the technology of coal mining also developer quickly, compare with before mine exploitation is much more centralize, production and new building mine are increasing accretion. Because of this the character of mine size, exploitation deep, assistant exaltation and gas effuse are gradually increasing.

同时，采煤技术也迅速发展，矿井开采的集中化程度日益提高，生产和新建矿井的井型日益增大，逐渐形成井田尺寸小、开采深度大、辅助提升任务大和瓦斯涌出量增加等特点。

Bao made another mistake. He incorrectly thinks that the emission line region is the same as accretion disk!

我们确实应当化更多的时间去了解现代对类星体的观测结果，了解现有的理论。

The results show that the system can keep certain smoothness with short delay, but the control precision can decline with the accretion of time delay, long random delay will not only reduce system expeditiousness, but also the smoothness and control precision at the same time. If the random delay is long enough, it can destroy the stability of networked control systems.

研究结果表明：系统在较小的延时下仍能保持一定的稳定，随着延时的增大，系统的控制精度有所降低；而较大的随机延时不但降低系统的总体快速性，同时，使系统的稳定性和控制精度明显降低，而当随机延时大到一定程度时，系统的稳定性难以保证。

Mafic granulite and gabbro xenoliths are also found in the same kimberlitic pipes from the Eastern-North China platform, and suggest that multi-accretion events took place. The gabbro was formed lighly earlier with the host kimberlite. The underplating of the mafic magmas was related to the continental orogeny in the late middle-Ordovician Period.

金伯利岩中强烈变质的基性麻粒岩以及变质不彻底的粗粒辉长岩在同一岩管中共存，表明华北古老岩石圈地幔所发生的多次增生作用事件，特别是后者的变质不彻底变质作用暗示其形成时代与金伯利岩相近，这种基性岩浆的底侵作用与华北地台中奥陶世晚期的造陆抬升有关。

The model results show that the hail embryos are mainly graupel particles.Solid phase precipitation accounts for 46% of ground precipitation amount and graupel-fall is 65% of solid phase precipitation.Graupel particles grow by accretion with rainwater and cloud water.Accumulation zone of supercooled water...

结果表明：玛曲冰雹云中冰雹胚胎以霰胚为主；在地面降水中，固态降水占降水总量的46%，而霰占固态降水的65%，霰主要靠撞冻雨水和云水增长；雹云中存在较弱的过冷雨水累积带，累积带的维持时间也很短，累积带中的过冷雨水有利于雹块的增长，但不起主要作用；雹块的增长主要是通过雹撞冻云水，其次是撞冻雨水增长。

Terrain heightened can enhance blocking effect, which lead to strengthen water vapor flux divergence and vertical convection, and cloud water increases but centralizes in the middle-low level. This change intensify accretion of snow by collecting more supercooled cloud water, and rain water converts into graupel by collecting more snow, and dry growth of graupel increase at the same time. Rain water augment because of more graupel melting, and rain water continue to increase by collecting cloud water in the low level.

地形高度增加后，阻挡作用加强，使水汽通量辐合加强，垂直气流增大，中低层云水增多，导致雪撞冻过冷云水增多，促使了雨水撞冻雪转化为霰和霰干增长过程的加强，霰融化为雨水增多，低层雨水碰并云水加强，冷云过程得到增强。

With this weakening of Brahmin influence they absorbed the grosser elements of low-grade popular worship, and became abused by the accretion of immoral rites and groveling superstitions.

这削弱了婆罗门的影响，他们吸收了大要素的低度流行的崇拜，成为滥用增生不道德的仪式和groveling迷信。

Although you receive no tangible income, you typically still have to pay federal income tax on the bond's accretion for the year.

虽然你没有收到实际利息，你仍必须为每年该债券增值支付联邦利息税。

Now there are two models regarding the massive starformation: infall and accretion model as does the low-mass star formation, andthe collision or merging of low- or intermediate-mass stars model.

对于大质量星形成过程目前主要有两个观点：类似于小质量星形成的吸积方式和由中、小质量原恒星并和形成方式。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
