查询词典 stellar

The best powder snow, where you sink to your knees while skiing, is made of stellar dendrites.

这是目前观察到最大的雪花晶体，落到地上的直径通常在5mm以上，尽管体积较大，但它仍为冰的单晶。

By analyzing numerically the disks around a young stellar object and a black hole, we can obtain: the dissipation can not be neglected as a magnetic field is in small threshold value; in Keplerian disks, the magnetic field is smaller, the dissipation caused by anomalous viscosity and anomalous resistivity deviates from the ideal more greatly; the dissipative effects on magnetic instability become smaller as the radius r becomes larger.

通过分析年轻恒星周围和黑洞周围吸积盘的数值解可以得到：在磁场比较小的一段阈值内，这种耗散过程是不可忽略的；而且，磁场越小，由反常黏滞及反常阻抗引起的耗散过程对磁不稳定性的影响就越大；离中心体的距离r越大，耗散过程对磁不稳定性的影响越小。

Age and metallicity are the most important parameters for stellar populations, but they are often found to be degenerated.

年龄和金属丰度是星族的两个重要参数，但两者相互简并。

The correlations of the specific star formation rate with stellar mass and metallicity are found.

发现星系的特征恒星形成率与恒星质量和金属丰度之间存在着显著的相关性。

The effect of metallicity can make this relation disperse in the V-band, but studies show that this is mainly limited to the case when the stellar mass is less than 0.6M (subscript ⊙).

尽管主序星的V波段质光关系由于金属丰度的影响而具有一定的弥散性，但有研究表明这种影响主要限于恒星质量小于0.6M的情况。

These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas.

这些星星是在约四万年前从星云原料中形成的，而他们的恒星风在星云的中心吹出一个洞，被一层的尘埃与炙热气体所隔离。

These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas.

在大约4百万年前，这些恒星从它周围的星云物质中形成的。它们所发出的恒星风在星云的中心挖出一个空洞，而空洞的边缘有一层由尘埃和炽热气的隔离层。

These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula's center, insulated by a layer of dust and hot gas.

在四百万年以前，星云物质聚集形成了这些恒星，它们的星风（一种从恒星不断向外运动的物质流，类似于太阳风）在星云中央清理出了一个空洞，这个空洞被一层尘埃和灼热气体所包围隔绝。

To investigate a nonplanar stellar motion deviating from the planar one, we approximately consider the motion as a bi-dimensional harmonic oscillator perturbed by higher order terms, so we obtain Henon-Heiles potential, which is nonintegrable.

为了研究试验粒子偏离赤道平面的运动，把整个运动近似地看成受到高阶微扰的二维谐振子，这时系统有不可积的Henon-Heiles势函数。

We are two resplendent suns—we it is who balance ourselves, orbic and stellar—we

视下面，我们是两个灿烂的太阳，我们在像星球般平衡

The quality of both red and white wine depends very much on the wine maker talent and on the quality of the grapes.

他的红酒和白酒的品质，根据酿造者的能力和葡萄的质量，各有差异。

No, I don't want to get drunk before my next match.

" "不，我不想让我的下一场比赛前喝醉了。
