英文摘要	The nuclear matter symmetry energy C-sym(rho) and its slope parameter L are studied using local density approximation. With this method, the symmetry energy of nuclear matter can be deduced from matter density distributions of finite nuclei. By systematically analyzing the extracted L for different isotopes, the variation trends of values of extracted L along isotopic chains can be obtained. The study can explain why the neutron rich nuclei in isotopic chains such as Pb-208 can be used to extract L under local density approximation. By studying the regularity of extracted L for different isotopic chains, we finally obtain the value of L and its error bar: L = 66 +/- 7 MeV. Besides, the density dependence parameter gamma is constrained to be 0.69 +/- 0.07 for the ansatz of symmetry energy C-sym(rho) = C-sym(rho(0))(rho/rho(0))(gamma).
