  • 專業解析

    pounds per square inch(縮寫為psi)是英制壓強單位,表示每平方英寸面積上施加的磅力。該單位廣泛應用于工程、機械和工業領域,主要用于測量氣體壓力、液體壓力或材料強度。其核心含義可拆解為:

    1. 力的基準:以磅(lb)為力的單位,1磅等于0.4536千克物體所受的重力
    2. 面積定義:平方英寸(in²)為面積單位,1平方英寸約等于6.4516平方厘米
    3. 壓強計算:通過公式 $$P = frac{F}{A}$$ 計算,其中F為磅力,A為平方英寸面積

    在工程實踐中,psi常用于測量輪胎氣壓(标準值約30-35 psi)、液壓系統壓力(工業設備可達3000 psi以上)以及材料抗拉強度測試。根據美國國家标準與技術研究院(NIST)的換算标準,1 psi約等于6894.76帕斯卡(Pa),而1标準大氣壓(atm)相當于14.6959 psi。該單位的權威定義可參考《國際單位制手冊》(BIPM出版)及ASTM國際标準文件E380。
