The pressure loss in the pipe of pneumatic conveying of waste plastics is one of the important parameters. 摘要在廢塑料氣力輸送過程中，管道壓力損失是重要參數之一。
Loss of pressure had not registered on the dials. 刻度盤未記錄壓力下降。
Hydraulic pressure has dropped to zero due to line leaking. 液壓力下降至零因漏油。
The steam pressure falls on account of condensation in the cylinder. 由於汽缸里的冷凝作用，蒸汽的壓力降低了。
The government has surrendered to pressure of big business and lowered tax rates. 政府屈服於大商業的壓力降低了稅率。
Runflat tires keep functioning safely for a specified distance at a specified maximum speed after losing pressure or blowout. 泄氣保用輪胎是失壓甚至爆胎后仍能繼續以較高速度安全行駛一段較長路程的輪胎。
