闡述恒溫恒濕測試機的濕度如何控制
闡述(shu)恒溫(wen)(wen)恒濕(shi)測試機(ji)的(de)(de)(de)(de)濕(shi)度(du)(du)如(ru)何(he)控制請問(wen)能夠生產只控制濕(shi)度(du)(du)而不(bu)控制溫(wen)(wen)度(du)(du)的(de)(de)(de)(de)設(she)備(bei)嗎(ma)?我(wo)們經(jing)常能夠聽(ting)到這樣的(de)(de)(de)(de)提(ti)問(wen)或(huo)者(zhe)是(shi)(shi)在討論(lun)環境試驗時(shi)只提(ti)濕(shi)度(du)(du)。設(she)備(bei)能僅控制溫(wen)(wen)度(du)(du)嗎(ma)?沒有任何(he)**性和可重復性。如(ru)果你只是(shi)(shi)想盡可能的(de)(de)(de)(de)更(geng)干(gan)或(huo)更(geng)濕(shi),那么拋開溫(wen)(wen)度(du)(du)控制是(shi)(shi)可以(yi)接受的(de)(de)(de)(de),但仍然(ran)需要測量(liang)溫(wen)(wen)度(du)(du)來計算濕(shi)度(du)(du)。(我(wo)們通常指(zhi)的(de)(de)(de)(de)濕(shi)度(du)(du)是(shi)(shi)指(zhi)相對濕(shi)度(du)(du),而不(bu)是(shi)(shi)單位空(kong)(kong)氣中的(de)(de)(de)(de)**含濕(shi)量(liang))通常情(qing)況下設(she)備(bei)上提(ti)到的(de)(de)(de)(de)相對濕(shi)度(du)(du)都與溫(wen)(wen)度(du)(du)相關(guan)聯。溫(wen)(wen)度(du)(du)越高,更(geng)多(duo)的(de)(de)(de)(de)濕(shi)空(kong)(kong)
