摘要： 本文中，我提议使用一个格点导数算符，在所有格点计算中都等价于理想的SLAC导数算符，但没有后者的高昂计算成本。 本文呈现了位置空间SLAC导数闭式表达式的教学性动机与推导，并详细介绍了其实现成本效益的方法。 显示英文摘要

摘要： In this paper I propose the use of a lattice derivative operator that is equivalent to the ideal SLAC derivative operator in all lattice calculations, but without the prohibitively expensive computational cost of the latter. A pedagogical motivation and derivation of the closed form of the SLAC derivative in position space is presented, and the proposed method for its cost-effective implementation is presented in detail.
