general collapse 中文意思是什麼
general collapse
解釋
大量巖石崩落-
General relativity ( as well as most other metric theories of gravity ) not only says that black holes can exist, but in fact predicts that they will be formed in nature whenever a sufficient amount of mass gets packed in a given region of space, through a process called gravitational collapse
廣義相對論（以及很多其它的米制引力理論）不只是說黑洞可以存在，而是事實上預言了它們將會自然形成只要在給出的空間區域質量聚集到足夠大，雖然過程稱做引力坍塌。 -
It is derived the hamiltonian for the interaction of a - type three - level atom with a two - mode quantum cavity field from the general interaction hamiltonian between a multi - level atom and a multi - mode radiation field, and reduce it into an effective two - mode raman - coupled mode under large detuning condition. it is proposed a modified effective hamiltonian for the two - mode raman - coupled model. it is found the time - dependent state vectors and present validity conditions for the involved interaction hamiltonians. it is shown that in the study of the two - mode raman - coupled model it is not enough to retain only the usually used effective hamiltonian, one must also take into account the ac stark shift of the atomic levels ( at least one of the levels ). finally, it is studied the atomic dynamics in the interaction of a - type three - level atom with a two - mode quantum cavity field and in the two - mode raman - coupled model. it is found that the number of collapse - revivals, the collapse time and the revival time show new characteristics
從多能級原子與多模光場的相互作用哈密頓量出發，導出了型三能級原子與雙模光場的相互作用哈密頓量.在大失諧條件下將其化成等效的二能級形式雙模喇曼耦合模型.提出了該模型的一個改進型等效哈密頓量.該哈密頓量由兩部分構成：一部為通常所謂的等效哈密頓量，另一部分描述原子能級的動態斯塔克移動.研究表明，在雙模喇曼耦合模型的研究中，只考慮前者是不夠的，還必須考慮後者.最後，我們研究了該系統中原子的動力學行為，發現崩塌-復甦的數目、崩塌時間和復甦時間均呈現新的特性 -
A burnedout star could collapse to so small a radius as to make the effects of general relativity quite important near its surface.
一個燃燒完的星球可能坍縮到如此之小的半徑，以致在其表面附近，廣義相對論效應相當重要。 -
But there was no general economic collapse in 1946
然而1946年並未出現總體經濟崩潰。 -
The bankruptcy of several small firms was the prelude to general economic collapse
幾家小商行倒閉了，隨之而來的是經濟大蕭條 -
So it would probably take a sharp drop in the stockmarket, or a general business collapse, to hurt the rich
所以，股市可能需要暴跌，或者商業的全線崩潰，才能給予富人以打擊。
