Preliminary evidence was obtained to prove the action of the position effect which has no relation to developmental phase on the grafts. A concept of positional information memory was proposed.

提供了与发育阶段无关的位置效应在嫁接中具有作用的初步证据，提出了“位置信息记忆”的概念。

The wireless sensor network routing has shortcoming which the data cannot reach in certain topology when completely uses the no state routing based on positional information, namely death points.

基于位置信息的无线传感器网络如果完全采用无状态的方式路由，在某些拓扑结构中存在数据不可到达的缺陷，即死亡点的问题。
