The state realization and the trellis diagram of a group code defined on lattices are studied .

将其建立在全序集上的概念推广到格上，研究了定义在格上群码的状态实现和 格子 图；

The trellis diagram of the natural state realization of the group code and the path through the trellis diagram of the group code are constructed .

构造了此类群码的自然状态实现的 格子 图和它的通过其格子图的途径；
