specified testing pressure的意思|示意

A common approach is hydrostatic testing-filling a closed pipeline section with water, then pressurizing the line to a specified pressure to check for leaks.

常用的试验方法为静水试压，即：向封闭的管段充水，然后把管段升压至规定压力，检查是否泄漏。

A leak detection and positioning system of oil pipeline based on dynamic pressure transmitter is designed, and the system composition and testing principle are specified.

设计了一套基于动态压力变送器的输油管道泄漏检测与定位系统，阐述了其系统组成和检测原理。
