1. The zerg player sends a drone out to establish a hatchery at his expansion point, but hides the drone off in the corner to prevent the SCV from blocking the expansion as it enters into the zerg base. 虫族玩家则用一个农民在分矿造下一个基地。他将农民放早一个角落以防止SCV干扰他放下分基地。
2. Pipe production line: Double wall Metal Reinforced Spiral Corrugated Pipe production line Double wall corrugated pipe, Steel plastic composite pipe and PE pipe and HDPE spiral pipe production line. 管道类——钢骨架增强缠绕波纹管、大口径双壁波纹管、钢塑复合管以及实壁或结构壁聚乙烯管成套生产设备。
3. Waste draining pipe, offlet or drain pipe should be connected to the main pipe; each pipe should connect two valves with the most possible short valve-to-valve pipe length. 排污管、放水管或疏水管应分别连接到各自的总管上，每管均应串接两个阀门，两阀门间的管段应尽量缩短。
4. HDPE pipe used for lining is penetrated into a concrete pipe then it forms pipe-in-pipe structure so as to raise pressure bearing capacity of the concrete pipe. HDPE管具有强度高、耐腐蚀、使用寿命长、管壁光滑、不结垢等优点，内衬HDPE管可与混凝土管形成整体性良好的管中管结构，使混凝土管承压能力大大提高。
5. Considering soil-pipe interaction, Boolean operator is used to merge site and pipe, and site-pipe physics contact is solved through soil-pipe friction. 考虑到场地和管道间的相互作用，在ADINA三维有限元建模过程中，应用布尔操作实现场地与管道间的几何融合，并通过管土摩擦解决场地与管道间的物理接触问题。
