对一维热传导方程来定式化的修正Ｌ．Ｃ－Ｎ方法．计算简单，无条件隐定．误差少的（计算量少）显格式方法．并且不连续的区域内也得到非振动得精确解．这种修正Ｌ．Ｃ－Ｎ方法更值得应用．同样对多维偏微分方程也可以应用．
Modification of a one-dimensional heat conduction equation to formalize. C-N method. Computation is simple and unconditional. Less error (less calculation) Significant format method. And the discontinuous area also get the exact solution of non-vibration. This correction C-N method is more applicable. The same applies to multidimensional partial differential equations.
