“压力差”常见的英文表达是 “pressure difference” 或 “pressure differential”。
pressure difference:是最常用、最直观的表达,强调两个不同位置或状态之间压力的数值差异。例如:The pressure difference between the inside and outside of the container causes air to flow in.(容器内外的压力差导致空气流入。)
pressure differential:在工程、物理等专业领域更为常用,尤其在涉及需要精确计算或控制压力差的场景中。例如:In this hydraulic system, the pressure differential drives the piston movement.(在这个液压系统中,压力差驱动活塞运动 。)
