摘　　要：爱因斯坦的广义相对论预言了引力波的存在.根据广义相对论,引力辐射是一种四极辐射.建立一个电学模型,将电四极辐射和引力辐射进行类比,得到双星系统引力辐射功率.所得结果与广义相对论的结论只差1/4的数值因子.As predicted by Einstein＇s GTR,gravitational radiation exists and is a radiation of quadrupole kind.A model is established in this paper,which,by making an analogy between electric quadrupole radiation and gravitational radiation,leads to a formula for the total radiation power of the gravitational radiation for a binary system,similar to the result given by GTR.In fact,the result obtained here differs from that given only by a numerical factor 1/4.
