查询词典 The Black Hole

In third chapter, We extend Horowitz and Maldacenas proposal about black hole final state to Dirac fields and find that if annihilation of the infalling positrons and the collapsed electrons inside the horizon is considered, then the nonlinear evolution of collapsing quantum state will be avoided.

在第三章中，我们把Horowitz和Maldacena关于黑洞终态的假设推广到了Dirac场并发现如果考虑黑洞蒸发过程中落进视界的负能粒子同黑洞物质之间的湮灭，那么出射态的非线性演化可以避免。

We investigate the linear stability of a shocked accretion flow onto a black hole with the following procedures: First, we study the stability in the inviscid isothermal limit.

我们按如下步骤研究了含激波的黑洞吸积流的线性稳定性问题：首先，我们研究无粘滞的等温吸积流。

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。

Reinhard Genzel obtained compelling evidence for this conjecture by developing state-of-the-art astronomical instruments and carrying out a persistent programme of observing our Galactic Centre for many years, which ultimately led to the discovery of a black hole with a mass a few million times that of the Sun, in the centre of the Milky Way.

莱因哈德E根舍对这个挑战性的猜测，找到了证据。他发展了最先进的天文设备，并持之以琣a对银河系中心进行长达数年的观测，终於笫一个获得确切证据，发现在银河系中心有一个黑洞，其质量是太阳质量的数百万倍。

I always turn back to look at the ruins, leaving images showing a deserted scene. There seems to be an unfillable black hole in my heart, and I am speechless when facing the ruins. I'm not sure whether I travel around to see the ruins, or to be seen by the ruins. If the image is a mirror, I'm probably trying to escape from the "self" in the mirror. Instead, I enter the illusion in the mirror to lose myself.

每每在废墟前频频回首，留下无人空景之影像，内心宛若填不完的黑洞，总是与废墟相对无言；虽不太清楚东奔西跑是为了欣赏废墟、还是被废墟观看，若说「对象物」是面镜子的话，那我大概是藉此逃避不愿面对镜中的那个「我」，遁入镜内无人的幻境中放逐。

Operating land from the original agreement to sell the public "Dr. film to" change the way, and some developers hoarding land in the way they are from the "black box" operation,"Happy property" into "get to bide one's time," or "digging a hole no longer building" New Tactics, a hoarding land.

经营性土地从原来协议出让向公开&招拍挂&方式转变，而部分开发商囤积土地的方式也由原来的&暗箱&操作、&跑马圈地&转变为&拿地后按兵不动&，或者&挖一个坑就不再建设&等新招，变相囤积土地。

At the center of the starburst rings is the Seyfert nucleus, the believed signature of a supermassive black hole that is accreting surrounding gas and dust.

人们相信，在赛费特星系的中心，存在黑洞，依据就是环绕着星系的气体和灰尘。

This region, which is the projection of a three-dimensional cone extending from the nucleus to the galaxy's halo, contains gas that has been heated by radiation emitted by the accreting black hole.

通过狭窄的滤镜，&V&字形的结构显得十分清晰：一个三维锥体的投影的区域从这个星系的中心一直延伸到星系的晕，当然，在这个锥体里，包含着被依附着的黑洞的辐射所加热的气体。

We argued that in the accretion disk around a black hole, it is significant in principle for considering the release of the internal energy of the accreting materials.

而且，当盘内物质的辐射机制是黑体辐射时，不论粘滞机制属于何种类型，结果都一样；对于自由—自由辐射，采用a粘滞律模型，与我们在文[1]中所得的结果十分类似。这表明文[1]中所取的近似足合适的。

There was a time, not so long ago, when the slot in the Yankees batting order belonging to the first baseman carried should have been sponsored by Maalox. For so long this season, it was a sickening, calcifying, echoing black hole. This, of course, was unacceptable.

不久以前，洋基先发一垒手的打席看起来就像是得到Maalox赞助一般，在今年球季的大半时间中，这个打席看起来就像是个被各项伤痛困扰缠身的黑洞，而这样的情况在洋基球团眼中，当然是无法接受的。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
