- In addition, each call stack is associated with a thread, so if you want to track call stack data, you ll need thread information as well. 另外,每個(gè)調用堆棧都與一個(gè)線(xiàn)程相關(guān),所以如果想跟蹤調用堆棧數據,也需要線(xiàn)程信息。
- Here, our own definition of a stack data structure and operations, the realization of the initial stack, push, pop, to determine whether the air, and destructors. 這里，我們自己定義了一些堆棧的數據結構和操作，實(shí)現了堆棧的初始化、push、pop、判斷是否為空、及析構。
- In this paper we discuss the difference and relationship between CRP and CRS stacking, NMO/DMO stacking, as well as pre stack depth migration(PreSDM) and CRS stacking in a geometrical viewpoint and on the hypothesis of constant velocity media. 以幾何描述的方式 ,在常速介質(zhì)假設下通過(guò)圖示定性描述CRP與CRS疊加之間 ,NMO/DMO疊加、疊前深度偏移 (PreSDM )與CRS疊加之間的區別與聯(lián)系。
