The purpose of this paper is to establish ordinary generating function and exponential generating function for the sequence of generalized stirling number of second kind, and some expressions of Generalized Stirling number of second kind are obtained. 本文旨在建立广义第二类Stirling数的几种不同形式的表示式。
Analysis the structural characteristics of the submerged jet and non-submerged jet, the ordinary cylindrical jet and the swirling jet, as well. Then cavitation jet generating conductions and cavitation jet function theory were studied. 研究了淹没与非淹没射流、普通圆柱射流与旋转射流流场的结构特性,对空化射流的产生条件以及空化射流中的空化作用进行了研究。
