构造一个与子移位不变相关的偏序集。描述了子位移的性质，也是拓扑共轭的不变量。如果此属性存在于子移位中，则构造的偏序集是偏序半群（为零）。在这些不变量的描述中，上下文的概念是有帮助的。
A partially ordered set that is invariantly associated to a subshift is constructed. A property of subshifts, also an invariant of topological conjugacy, is described. If this property is present in a subshift then the constructed partially ordered set is a partially ordered semigroup (with zero). In the description of these invariants the notion of context is instrumental.
