查询词典 metallicity

In this thesis, we study the relation between the critical accretion rate and the metallicity via AGB stars approach.

在本文中我们通过AGB星研究了此临界吸积率和金属丰度之间的关系。

≤0.3. Second, applying a set of absorption-line indices to the Merit Function for Galactic and M31 globular clusters and the circumnuclear region of M32, we obtain their age and metallicity.

其次，将简单单星族的Lick/IDS系统谱指数应用于品质函数，给出了一些银河系和M31的球状星团，M32中心区域的年龄和金属丰度。

Our observations do not suggest that Li is unaffected by metallicity and/or age.

但是我们的观测不能锂一点也不受恒星金属性或年龄的的影响。

It is known that solar-type stars with high metallicity have a high probability of hosting planets.

因此，高金属性的类太阳恒星很有可能被行星绕转。

These two clusters offer a homogeneous sample of solar analogues in terms of age and metallicity.

这两个星团为我们提供了在年龄和金属性商同种性质的类太阳样本。

We now discuss the impact of age and metallicity on the Li abundance of solar analogue stars.

现在我们主要讨论的是：&类太阳&恒星中，与锂含量有关的恒星年龄和金属性效应问题。

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 result indicates that the critical accretion rate is affected not only by the hydrogen mass fraction and the core mass, but also by the metallicity, though the effect of the metallicity is smaller than that of the core mass.

研究结果表明，此临界吸积率不但是核质量的函数，同时还是金属丰富的函数，但金属丰度的影响比核质量的影响要小。

In connection with the age-metallicity relation, we confirmed the Edvardsson et al's discovery of a substantial dispersion imposed on a weak correlation between age and metallicity; this result is also valid for the age-kinematics relation.

首先，我们的研究进一步证实了Edvardsson等人发现的结果，即在年龄和金属丰度关系中存在相当大的弥散。这种弥散也存在于年龄和动力学关系中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
