摘　　要：调频网点的生成体现随机性,其加网效率与多种因素相关。本文重点讨论乘同余伪随机算法生成调频网点的效率问题。首先介绍了伪随机算法用于调频加网生成网点的基本原理,在此基础上讨论了乘同余伪随机算法实现调频加网的方法机制,同时提出5种可用于调频网点生成的随机函数,并通过定量实验对5组乘同余伪随机函数生成随机数效率进行了讨论和研究。通过分析数据和曲线走势图,得出不同条件对加网效率的影响趋势,为调频加网用于印刷生产提供了理论参考。The generation of FM dot represents randomicity and its efficiency is relevant to various factors. In this paper, the issue of FM dot generation efficiency with multiplicative congruence pseudo-random algorithmic was specifically discussed. Based on the principle of pseudo-random algorithmic used in FM screening dot generation, the mechanism of multiplicative congruence pseudo-random algorithmic aimed to realize FM screening was discussed. Meanwhile, five random functions which could realize FM dot generation were brought forward and the random numbers generation efficiency of five multiplicative congruence pseudo-random functions was studied through quantificational experiments. By analyzing data and curve diagrams, the influence tendency of different conditions on the efficiency was got, which would provide theory reference for FM screening used in printing.
