Subsequently, the waves induced forces and their driven effects on currents are studied in detail. in the discussion of the effects of currents on waves, according to the wave radiation theory and the law of wave action conservation, the equivalence of none vorticity condition of the vector of wave number in constant wave field and fermat theory is testified. the dynamic and kinematics effects of background currents on waves are introduced concisely
在流對浪的作用討論中,依據波動的射線理論和由變分原理導出的波作用量守恆定律,闡明了穩定波場波數矢量的無旋條件與費馬原理的等價性,扼要討論了背景流場影響海浪的運動學效應和動力學效應,首次指出水位(包括天文潮位與風暴潮位)變化對海浪成長與消衰的影響,為流浪潮聯合數值模式的發展提供必要的理論依據。They found two events showing the shortening of pulsating cycle and decaying of radiations intensity. the signatures matched theories of what scientists would predict to see. when matter is falling so close to the event horizon, it will be circling the black hole with increasing speed and its light will rapidly dim as it is stretched by gravity to ever - longer wavelengths
研究人員分析了極大量來自緻密天體天鵝座xr - 1的紫外線輻射,發現其中兩組數據顯示,輻射脈沖的周期隨時間縮短,而其強度則隨時間衰減至消失,這現象與一些物質在接近黑洞視界時繞著黑洞急促旋轉,放出的輻射因為重力紅移而衰減的情況相符。
