中文摘要：
证明了林建国等（林建国，谢志华，周俊陶．任意精度的三点紧致显格式及其在CFD中的应用．应用数学和力学，2007，28（7）：843-852）提出的紧致显格式与传统的差分格式实质相同，是传统差分格式的另一表达形式，并不具有紧致格式的优点．尽管如此，但这种表达形式更紧凑，推导获得高精度的差分表达式相对于传统的Taylor展开求待定系数的方法也更加简单．
英文摘要：
It was proved the explicit compact difference scheme, which was proposed by Lin et al. （Three-point explicit compact difference scheme with arbitrary order of accuracy and its application in CFD.Applied Mathematics and Mechanics,2007,28 （ 7 ）：843-852 ） has the same performance as the conventional finite difference schemes and it is actually another expression form of the conventional fi- nite difference schemes. Though the proposed expression down＇ t have advantages of a compact difference scheme, it is easier to be obtained and implemented in a code compared to the conventional expression in which the coefficients should be obtained by solving equations especially for higher accurate schemes.
