查询词典 accretion

The build-up of dark haloes in CDM models generally consists of an early phase of fast accretion and a late phase of slow accretion .

我们同时发现：(1)冷暗物质模型中暗晕的成长均包括一个早期的快速吸积阶段暗晕质量M_h随时间的增长远快于宇宙的膨胀速率」和一个晚期的缓慢吸积阶段！

The expansion of the H II region produced by the large flux of ionising radiation can significantly reduce the accretion rate when the protostar reaches 50 100M, but accretion can continue in the equatorial plane.

当星坯的质量达到50-100太阳质量的时候，电离辐射产生的HII区的膨胀可以大大削减吸积率，但是在赤道平面上的吸积过程依然可以继续。

It is shown that these evolution characteristics in retrograde accretion are very different from those in the prograde case. The temperature of black holes decreases monotonously in prograde case, while it has a maximum in retrograde case. The entropy of black holes always increases in the whole accretion process, and the rates of change of the entropy in retrograde case are much larger than those in the prograde case.

结果表明，黑洞的温度和熵在逆行吸积与顺行吸积中的演化特征很不相同：在顺行吸积中黑洞的温度单调减小，而在逆行吸积中黑洞的温度存在一个极大值；在吸积的全过程中，黑洞的熵始终是增加的，而且逆行吸积中黑洞熵的变化率要比顺行吸积中的黑洞熵的变化率大得多。

The prograde path was related to the magmatic accretion in arc settings, indicating the existence of an arc setting during the MesoproterozoicNeoproterozoic period. The retrograde near-isobaric cooling path after the peak metamorphism reveals that rapid erosion did not occur and sustained heat supplies from the upper-mantle were maintained after magmatic accretion in the Yuanmou area.

该轨迹的进变质阶段与岛弧地区的岩浆增生过程密切相关，指示元谋地区在中-新元古代期间(1.0～0.85Ga)存在岛弧构造环境；峰期之后的近等压冷却退变轨迹表明该地区未经历强烈的剥蚀，并可能有深部热流的持续供给。

There's been abundant allocution afresh a part of leaders of western governments (as they attending advanced to the G8 acme in Scotland in July) about what can be done to advice Africa. There's been altercation about accretion aid, cancelling debt and accouterment fairer trading conditions.

最近有很多关于欧洲国家领导人将如何帮助非洲国家的言论（八国首脑会议即将在七月份于苏格兰召开）有人说会增加援助，取消债务以及给非洲国家更公平的贸易条件。

This, then, which has received the accretion, changes, not that which thy mother brought forth.

那么，得到生长、变化的这一切，并不仅仅是你母亲所产生的。

In the last chapter, we present our prospect to the developments and the applications of our shock-included accretion theory.

在最后一章，我们对含激波的吸积理论的发展及应用作了一些展望。

It is useful to solve accretion of estimation error and filter divergence in practice.

这将有助于解决卡尔曼滤波器在实际应用中估计误差增大和滤波发散等问题。

Both halftone dot accretion and relative contrast are the important parameters of printing quality control system based on density.

网点增大和相对反差是基于密度的印刷质量控制体系中两个重要的控制参数。

Stability properties and oscillation modes of accretion disks around compact objects are studied in this paper.

研究了环绕致密天体的吸积盘的稳定性质和振动模式。

I'm not an actor. I'm a professor of paleontology.

我不是演员，我是古生物学教授
