| 摘 要： | 跟核物质主要特性相一致的相对论性平均场理论被用来研究核物质里的类声集体模式的激发。已自洽地求出对应于相对论平均场耦合方程组的数值解,并计算出核子的有效质量、类声波速度和类声解的振幅。当核密度靠近或者大于核物质的饱和密度时,这样的类声波非平庸解是可以存在的。

| Abstract: | The relativistic mean field theory consistent with bulk properties of nuclear matter is extended to study the excitations of the sound-like collective modes in nuclear matter. Corresponding relativistic mean field equations are solved numerically and self-consis-tently. The effective mass of nucleon the speed of the sound and the amplitude of the sound-like solution are calculated. When the nuclear density is near or greater than the saturation density, the sound-like non-trivial solution could be found. |
