It is proved that the evolution characters are affected by the interaction between the central black hole and the accretion disk.

These results are consistent with the scenario of small black hole and high accretion rate for NLS1s.

这些结果与窄线SeyfertⅠ型星系的小黑洞高吸积率模型一致。

The accretion onto the black hole is the source of the quasar's energy.

黑洞吸积是类星体的能量来源。

Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

另外的关于2 GeV以上能谱变软的可能解释是高能光子和寄主活动星系核的软X射线辐射场通过电子对产生反应而被吸收，但是这个解释要求反应区域要很靠近中心黑洞(1~100倍引力半径)，这和3C 454.3的X射线测量谱相矛盾。

For a ghastly moment I thought he might be planning a soundtrack full of l960s pop hits — that black hole compounded of Cliff Richard, Paul Anka, Liberace, Lonnie Donegan — but Nick said no, he wanted to know what I and my schoolmates really listened to.

在一个极令人不快的时刻，我认为他正在计画一个全部是六十年代的流行音乐的电影配乐——由Cliff Richard、Paul Anka、Liberace和Lonnie Donegan的音乐混合而成的黑洞——但是Nick说不是的，他想要知道我和我的同学们实际上听什麽。

This dissertation is mainly about the scalar field in curved black hole spacetime backgrounds assumed to be asymptotic de Sitter space at infinity.

本文的主要内容是关于黑洞视界外部时空中的标量场，我们选择的黑洞时空在无穷远处是渐近de Sitter时空。

Microsoft's COM technology can be considered as an analogous to black hole in astronomy.

可以把微软的COM（Component Object Model组件对象模型）技术比作天文学中的黑洞。

Quite possibly. The Cygnus X-1 binary star system contains one of the best candidates for a black hole.

很可能！双星系统天鹅座X-1是最佳的恒星黑洞候选者之一。

He spent 10 years talking about the black hole of time to study, he said:"It seems a bit like looking in the coal cellar with only a black cat."

谈到花费了他十几年时间的黑洞研究时，他说道：&这似乎有点像在煤窖里寻找在只黑猫。&

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.
