9、是压力表上指示的压力;压力表是从0开始记数的,而大气本身就有1公斤的压力，绝对大气压=表压+1),184度是11公斤绝对大气压下的饱和蒸汽对应温度。这里都强调“饱和蒸汽”，因为还有“过热蒸汽”，过热蒸汽的温度是不于压力成对应关系的。Antoine公式: ln(P)=9.3876-3826.36/(T-45.47)【T在290500K之间】 P：MPa T：K 我用这个公式算出来是T=452.77K 约179度.不知道对不对?请高手指教!饱和蒸汽压力、温度对照表制硝 2008-05-24 10:53:57 阅读16207 评论10 字号：大中小订阅 压力MPa温度压力MPa温度压力MPa温度压力
