This paper puts forward a new method for laser speed measurement with half polarity correlation.
提出了一种激光测速的新方法——半极性相关法，它既具有极性相关法中数字信号便于延迟的优点，又保留了经典相关法中不丢失幅度信息的长处。
In this paper,we find necessary and sufficient conditions that any compact set is essentiallyb polar set of α- self - similar Markov processes and consider some relationships the polar set with essentially polar set and semipolar set.
本文我们给出了任意紧集不是自相似马氏过程的本性极集的充要条件，并讨论了自相似马氏过程极集，本性极集，半极集之间的关系。
