水汽壓（e）：是水汽在大氣總壓力中的分壓力。它表示了空氣中水汽的含量的大小，以毫巴為單位。空氣吸收水汽有一定限量，達(dá)到了限量就不再吸收，這個(gè)限量叫“飽和點(diǎn)”。空氣中水汽達(dá)到飽和點(diǎn)時(shí)的水汽壓，稱為飽和水汽壓（或稱比較大水汽張力）。飽和水汽壓是溫度的函數(shù)，隨溫度升高而增大。在同一溫度下，純冰面上的飽和水汽壓要小于純水面上的飽和水汽壓。 </p> <p> <br /> </p> <p> 相對(duì)濕度（rh）：濕空氣中實(shí)際水汽壓e與同溫度下飽和水汽壓E的百分比，即 </p> <p> rh =（e/E）* </p> <p> 相對(duì)濕度的大小能直接表示空氣距離飽和的相對(duì)程度。空氣完全干燥時(shí)，相對(duì)濕度為零。相對(duì)濕度越小，表示當(dāng)時(shí)空氣越干燥。當(dāng)相對(duì)濕度接近于時(shí)，表示空氣很潮濕，越接近于飽和。山西口碑好的濕度發(fā)生器廠家報(bào)價(jià)便攜式濕度發(fā)生器產(chǎn)品介紹。</p><div
