中文摘要：

在带微观三体力的Brueckner-Hartree-Fock方法下研究了非对称核物质的不可压缩系数,得到了不可压缩系数的同位旋以及密度依赖,并做了进一步的讨论。在一定密度下,不可压缩系数作为同位旋非对称度的函数随同位旋单调递增。预测了非对称核物质在平衡态的同位旋依赖性质并与其他理论方法做了比较。

英文摘要：

We have investigated the incompressibility of asymmetric nuclear matter within the Brueckner-Hartree-Fock approach extended to include a microscopic three-body force.The isospin-dependence and density-dependence of the nuclear incompressibility have been obtained and discussed.It is shown that the incompressibility at a fixed density increases monotonically as a function of isospin asymmetry.The isospin asymmetry dependence of the equilibrium properties of asymmetric nuclear matter is also predicted and compared with the results of other theoretical approaches.
