摘要
研究两区球体介质系统,球体内为稀疏介质Ⅰ,球外为无限均匀介质Ⅱ,在介质Ⅱ内建立非定态中子年龄方程,给出了定解条件,用拉普拉斯变换得到方程的解析解。
A system of two homogeneous regions is studied in this paper. The first region Ⅰ is a sphere of radius with dilute, slight scattering and arbitrarily absorbing medium. The second region Ⅱ is an uniform infinite medium surrounding the sphere. The timedependent neutron age equation with initial and special boundary conditions is established for region Ⅱ. The analytical solution of the equation is obtained by use of the Laplace transform.
