gravitational radiation meaning in English
引力辐射
重力辐射
Examples
- But because sources of gravitational radiation are poor emitters of light , astronomers may have missed still unknown classes of objects . “ the first thing we might see may be something unanticipated
然而由于重力辐射源可能不太发光，说不定天文学家从未侦测到这一类天体。 - Finally , the duality between the gravitational radiation and the electromagnetic radiation is researched because of the similarity between them in the weak field situation
最后，本文考虑到弱场线性近似条件下引力辐射与电磁辐射的类似，故讨论了引力辐射与电磁辐射之间的对偶关系。 - In addition , using the rough quantum theory of gravity , the quantum form of gravitational radiation in weak field is discussed , which is coincident with the classical results , and the calculation program does not need many operators
另外本文采用简化的量子观点讨论了弱引力场引力辐射的量子表述，计算过程并未涉及大量的算符运算，而且运算结果表明它与经典小参数法得到的相应辐射形式是自洽的。 - 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
我们计算了由引力波辐射引起双星系统的角动量损失的演化模型，发现双星系统还是经历循环演化，不过循环的周期变短，且双星系统的每一个循环处在半接状态的时间与处在相接状态的时间之比变小。 - 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
本文采用小参数法作为经典引力辐射的研究方法对引力辐射作多极展开，得到各极引力辐射的一般表达式，并给出了沿任一方向引力辐射的角分布的严格证明，这种展开法在处理四极以上的高阶引力辐射时却可以不涉及更高阶的张量计算。
