-The generalized MacWilliams identities are given for the support weight distribution of a quaternary linear code with type 4k and that of its dual code. 对于类型为4~k的四元线性码,建立了联系它与其对偶码的支集重量分布之间的MacWilliams恒等式;
The rule of distinguishing triangle direction is given out. The algorithm of neighbor finding from back to front with decomposing Quaternary code is presented. The analysis of time complexity between this decomposing algorithm and bartholdi's algorithm is approached. 分析了球面Quaternary编码的特点,给出了三角格网方向判断的规则,并对该算法与Bartholdi邻近搜索算法的时间复杂度进行了对比。
