spinning mass 中文意思是什麼
spinning mass
解釋
旋轉質量-
The world is a spinning mass of fertile material for you, and whatever puts a glimmer in your eye, a bounce in your step, or a curse upon your lips is what you should write about
這個世界變化不停，為您提供了豐富的素材-有些讓您眼放微光，有些讓您腳生羈絆，有些讓您口吐怨言-無論是什麼，您都應提筆一記。 -
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。 -
The simulation results show that the shaped degree is decreasing when the spinning temperature and intrinsic viscosity are increasing ; the spinning speed has little effect on the shaped degree when the pump mass throughput is constant ; the shaped degree is increasing with the increasing of pump mass throughput when the spinning speed is constant ; the cross air - blow conditions have much effect on the shaped degree ; the scope of shaped cegree is increasing when the aspect ratio of spinneret hole is increasing ; the shaped degree has obvious decreasing tendency in the small zone of spinning path and this decreasing became gently when the pump mass throughput is increasing
模擬的結果表明：扁平纖維的異形度隨著紡絲溫度及特性黏度的升高而降低；泵供量一定時，紡速對異形度的影響不大；紡絲速度一定，異形度隨著泵供量的增大而增大；吹風條件對異形度的影響較大；隨著噴絲孔的長寬比的增大，異形度增加的幅度也較大；異形度在紡程上較小的區間內有明顯的下降趨勢，並隨著泵供量的增加其下降的趨勢變緩。
