本文从理论上系统的研究了循环冗余校验（CRC）码的原理和性质,解决了在实际应用中经常碰到的如何设置寄存器的初始值及如何选取生成多项式的问题;同时,通过分析不同长度下算法的性能差异提出了CRC算法对校验数据的长度没有限制的观点。最后,提出了CRC逆运算的概念。

In the article the principle and property of cyclic redundancy check（CRC） are studied theoretically,which solved the problems of setting the initial values of the register and selecting the generation polynomials.Meanwhile,it presents the viewpoint that there is no limit for the length of the calibration data by the CRC algorithm and analyzes the performances of the algorithm using different lengths.Finally,a general idea of reversing CRC is presented.
