查询词典 black hole

This model considers the flow of energy between two regions around the black hole : an inner region that is close to the so--called event horizen (the boundary beyond which even light cannot escape ), and an outer region that includes the black hole's fuel source-- the young stars--extending up to a million times father out .

此模型分析围绕在黑洞周边的两个区域间的能量流：内部的区域接近于视界（一个理论上的边界，超过此边界甚至光都无法逃脱黑洞的吞噬），外部区域包括黑洞的燃料源——年青的恒星——并继续扩展数百万倍。

Give out the trigonometric function solutions of fourth order equations, as a example with rectilinearly accelerating the Kerr black hole, the event horizon of non sphere symmetric and non stationary black hole are studied.

Estimating by the area principle of the Black Hole, 29 percent of rest mass of Black Hole can be released.

通过黑洞的面积原理估计出，黑洞静止质量的百分之二十九是可以释放的。

Showing one more unit - warped in in a serious of cubes - giant floating base - called a protoss mothership - can only have 1 at a time - cost big resources - special abilities include timebomb that slows all enemy missiles inside - shows terran missle launcher shooting in projectiles that stop in the field before they reach the ship - when field ends missiles drop the ground - planet cracker attack - giant lasers stream from ship to ground - ship can be moved around while planet cracker laser is active - the ship looks like a metallic, triangular sand dollar - mothership can create a black hole anywhere it wannts to - creates distortion that actually sucks ships in and destroys them - in the demo the black hole destroyed four terran battle cruisers in about ten seconds.

In Chapter 2, we study exact solutions of the separated parts of Klein-Gordon field equation on some stationary and axisymmetry black hole backgrounds. We demonstrate that the radial and angular parts of a massive scalar field equation in the Kerr-Newman and Kerr-Sen black hole space-times satisfies the generalized spheroidal wave equation which is, in fact, a confluent Heun equation.

在第二章中我们研究了稳态轴对称黑洞背景几何中Klein-Gordon场方程分离变量部分的精确解，表明了Kerr-Newman黑洞及Kerr-Sen黑洞中有质量复标量场方程的径向部分和角向部分均满足广义椭球波方程，而后者实际上就是合流的Heun方程。

A black hole forms inside surrounded by a disk of accreting matter, and, within a few seconds, launched a jet of matter away from the black hole that ultimately made the gamma-ray burst. Here we see the jet breaking through the outer shell of the star, about nine seconds after its creation.

在太空中平均每天可以探测到一段出现一瞬间的高能量伽玛射线，而计算显示这秒钟的能量大约有一整颗恒星那麼大，天文学家称此为伽玛射线暴。

A few days ago, in the one act with the 10 thousand astonishing discovery before amounting to door of square new world, the floor of when everything is all right appeared suddenly a striking picture: Ground cave in does not see the black hole of the bottom greatly into, the buy in the black hole is worn ATM machine line, and thick network connects line crystal head to taking in and send out in large quantities money... somebody is loud debunk answer to a riddle:"This is not true ground cave in, this is three-dimensional stereograph!"

日前，在万达广场新世界门前发现惊人的一幕，好端端的地板突然出现了一幅惊人的图像：地面塌陷成一个深不见底的黑洞，黑洞里置着ATM机线，而粗大的网络连线水晶头正在吞吐着钞票……有人大声揭穿谜底："这不是真的地面塌陷，这是三维立体画！"

It is shown that if the author ignores the usual contribution from the vacuum surrounding the system, then the statistical entropy consists of a quadratically divergent term which is proportional to the horizon area of the black hole and two logarithmically divergent terms, the structure of the whole expression is different from that of the black hole entropy.

结果表明，忽略远离围绕系统的真空的贡献，Dirac场的统计熵包含与黑洞视界面积成正比的平方反比发散项和对数发散项，整个表达式的结构与黑洞熵的结构不一样。

A security enhancement scheme is proposed to encounter the black hole attacks in aodv protocol . this scheme may solve the black hole problem and prevent personating the destination node to some degree .

针对移动adhoc网络aodv协议中所存在的黑洞攻击，提出了一种增强安全性的解决方案，该方案能在一定程度上解决黑洞问题并可防止假冒目的节点攻击。

After perturbing a black hole,there is a quasinormal ringing outside the black hole.

研究黑洞拟正则模的动因之一就是确定黑洞的特征参量。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
