21、应的饱和蒸汽温度就是 179 度,楼上的说的 184 度是 10 公斤表压(也就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-
