We calculate a model with angular momentum loss caused by gravitational radiation, and find that the binary undergo cyclic evolution as well. however, the period of the cycle becomes shorter, and the ratio of the time spent in the semi - detached phase to the time spent in the contact phase in a cycle becomes smaller
我們計算了由引力波輻射引起雙星系統的角動量損失的演化模型，發現雙星系統還是經歷循環演化，不過循環的周期變短，且雙星系統的每一個循環處在半接狀態的時間與處在相接狀態的時間之比變小。 -
In this paper, the method of small parameter is used to calculate the multipolar expansion of gravitational radiation in classical situation, and the general expression on multipolar gravitational radiation is obtained. then the angle distribution characters in an arbitrary direction are given. this expansion method can avoid the higher order tensors when dealing with the gravitational radiation higher than quadrupole
本文採用小參數法作為經典引力輻射的研究方法對引力輻射作多極展開，得到各極引力輻射的一般表達式，並給出了沿任一方向引力輻射的角分佈的嚴格證明，這種展開法在處理四極以上的高階引力輻射時卻可以不涉及更高階的張量計算。 -
