By means of particular analyzing and comparing with the structure, control, features and application on different solutions of particle volume metering and weight metering, the authors have given out some suggestions on how to choose the metering and controlling schemes.
本文通过对刨花体积计量和重量计量不同方案的结构、控制、特点及应用情况的详细分析和比较,提出了选用刨花计量与控制方案的建议。
In this paper,weight enumerator of codes over Z8 and the generalization of MacWilliams identity are proposed.
研究了Z8-码的重量计数器以及广义的MacWilliams恒等式,同时研究了两个与Z8-码C相关的码C(1)和C(2)的特性,得到了如下结论:若Z8-码C是自正交的,则C(1)和C(2)是自正交的四元码;若Z8-码C是类型为8n2的自对偶码,则C(1)是自对偶四元码。
The definitions of the Lee complete ρ weight enumerator and the exact complete ρ weight enumerator over Mn×s(F2+uF2) were given, and the Macwilliams identities with respect to this RT metric for the two weight enumerators of linear codes over Mn×s(F2+uF2) were given respectively.
定义了环Mn×s(F2+uF2)上码的Lee完全ρ重量计数器和精确完全ρ重量计数器,给出了环Mn×s(F2+uF2)上线性码关于这两种重量计数器相应的MacWilliams恒等式。
By implementing Visual C++ procedures,we obtained such new extremal codes and determined the codes to meet the weight enumerator W2.
给出了构造码长为38的具有3-(12,2)型自同构的二元自对偶极值码生成矩阵算法,并通过运行V isual C++程序,首次得到了这样的极值码,判定新构造码的重量计数子是W2。
