Until about ten years ago, we believed that the only properties we can tell about a black hole are its mass, angular momentum loosely speaking its spinning rate and its electric charge. two black holes that have the same mass, angular momentum and charge will behave in exactly the same way. in particular, it does not depend on what kinds of material it forms from
原理：十年之前，我們相信黑洞是一個很簡單的物體，三個物理參數質量角動量如要求不嚴謹，可把它看成為自轉速度和電荷便決定了它的一切，兩個黑洞只要它們這三個參數相同，物理特性便完全一樣，黑洞最初由甚麼物質所造成是無關宏旨的，由於黑洞是這樣單純，光禿禿沒有甚麼特徵，所以天文學家謔稱黑洞沒有毛發。 -
That is the following in essence. a sufficient mass of cold matter will necessarily collapse to a black hole, and stars with different mass will evolve into the white - dwarf - star, the neutron - star or the black - hole eventually because of the radiation of the burning core. the collapse of stars with sufficient mass leads to a black hole endowed with mass and charge and angular momentum, no other adjustable parameters : " a black hole has no hair.
第二章簡單介紹一下「黑洞無毛」理論形成，即足夠質量的冷物質能夠塌縮成黑洞，不同質量的恆星由於核燃燒輻射最終會演化成為白矮星、中子星或黑洞，以及黑洞的終態系統唯一地由質量、電荷和角動量確定，而無其它物理參數，此即為「黑洞無毛」理論。 -
The backdrilled hole can be offset or angular to the spring ' s natural center line and exploits the spring ' s natural tendency to straighten, generating a sound side loading between plunger and barrel at all times
后鉆孔可以偏離彈簧自然中心線，或與中心線呈一個角度，利用彈簧的自然趨勢伸直，在頂針和客體之間始終形成一個可觀的側作用力。 -
Objects grazing the ergosphere could in some circumstances be catapulted outwards at great speed, extracting energy ( and angular momentum ) from the hole, hence the name ergosphere ( " sphere of work " ) because it is capable of doing work
擦過能層的物體就會在某個情形下以極大的速度彈射出去，從黑洞里提取能量（與角動量） ，因此叫能層（ 「做功的球）因為它有能力作功。 -
Firstly, this article introduces the transforming principle and means from airspace to angular spectrum space, then it calculates square hole diffraction, at last it compares the theoretical calculation with the experimental result, which turns out to be good and fit
本文首先介紹了由空域到角譜域的變換原理和方法，然後對方孔衍射作了計算，並同實驗結果作了比較，結果表明兩者十分吻合。
