blackhole简意就是黑洞的意思，在专业术语中，有后门程序的意思。 扩展资料 后门程序一般是指那些绕过安全性控制而获取对程序或系统访问的程序方法。在软件的开发阶段，程序员常常会在软件内创建后门程序以便可以修改程序设计中的缺陷。但是，如果这些后门被其他人知道，或是在发布软件之前没有删除后门程序，那么它就成了安全风险，容易被黑客当成漏洞进行攻击。

黑洞的英文是什么?

General relativity predicts a particularly dense dark objects. Evolution of massive stars in their late collapse occurs, the dense material in particular, it has one called event horizon of the closed border, a black hole hidden in a huge gravitational field, due to the gravitational field so strong, including in particular photon (ie the composition of light particles, the speed c = 3.0 × 10 ^ 8m / s), including any material can only be entered could not escape. The formation of a black hole minimum mass star's core is about three times the solar mass, of course, this is the last star of nuclear quality, rather than main sequence stars in the period of quality. In addition to this stellar-class black hole, there are other sources of black holes - the so-called micro-black holes may be formed in the early universe, the so-called supermassive black holes may exist in the central galaxy. A black hole can be found through the concept of electronic equipment.
The black hole within its borders to prevent any outsiders to see anything, which is the object known as the black hole of the reason. We were unable to observe the reflection of light it can only be affected indirectly understand the objects around the black hole. Having said that, but the black hole still has its borders, namely event horizon (horizon). It is assumed that the evolution of stellar black hole of death matter, is in a special super-massive stars collapse generated. In addition, the quality of a black hole must be larger than the Chandrasekhar limit of stellar evolution to the end of the form, quality, smaller than the Chandrasekhar limit of the star is unable to form a black hole.
翻译成汉语就是下面的意思----
广义相对论预言的一种特别致密的暗天体。大质量恒星在其演化末期发生塌缩，其物质特别致密，它有一个称为“视界”的封闭边界，黑洞中隐匿着巨大的引力场，因引力场特别强以至于包括光子(即组成光的微粒，速度c=3.0×10^8m/s)在内的任何物质只能进去而无法逃脱。形成黑洞的星核质量下限约3倍太阳质量，当然，这是最后的星核质量，而不是恒星在主序时期的质量。除了这种恒星级黑洞，也有其他来源的黑洞――所谓微型黑洞可能形成于宇宙早期，而所谓超大质量黑洞可能存在于星系中央。黑洞可以经由电子仪器观查到。
黑洞不让任何其边界以内的任何事物被外界看见，这就是这种物体被称为“黑洞”的缘故。我们无法通过光的反射来观察它，只能通过受其影响的周围物体来间接了解黑洞。虽然这么说，但黑洞还是有它的边界，即“事件视界（视界）”。据猜测，黑洞是死亡恒星的演化物，是在特殊的大质量超巨星坍缩时产生的。另外，黑洞必须是一颗质量大于钱德拉塞卡极限的恒星演化到末期而形成的，质量小于钱德拉塞卡极限的恒星是无法形成黑洞的。
