;  恒溫(wen)恒濕(shi)試驗箱很多人在選購(gou)的(de)(de)時候不知道什(shen)么叫(jiao)做線性和非線性的(de)(de)區別(bie)，下面廣東劍喬小編給大家(jia)普(pu)及一下：

   線性恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)試(shi)驗箱是恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)試(shi)驗箱運行期(qi)間(jian)(jian)，其加熱速(su)率和冷卻速(su)率恒(heng)(heng)(heng)定一段時(shi)間(jian)(jian)。國家標準(zhun)規(gui)定“平均(jun)每5分(fen)(fen)鐘”。例如：在(zai)一定時(shi)間(jian)(jian)內(nei)恒(heng)(heng)(heng)溫恒(heng)(heng)(heng)濕(shi)試(shi)驗室每分(fen)(fen)鐘提(ti)高5分(fen)(fen)鐘的平均(jun)值，那么整個時(shi)期(qi)的加熱速(su)率是每5分(fen)(fen)鐘幾度，有時(shi)每5分(fen)(fen)鐘不(bu)是2度。分(fen)(fen)鐘。有時(shi)它(ta)每5分(fen)(fen)鐘4度；出(chu)于同樣(yang)的原(yuan)因，冷卻速(su)度是相同的。總之，溫度的上(shang)升和下降只能(neng)是每5分(fen)(fen)鐘幾度，它(ta)不(bu)會(hui)改變。 

   非(fei)線(xian)(xian)性恒(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)濕(shi)(shi)試(shi)驗(yan)箱是溫(wen)(wen)(wen)度(du)(du)上(shang)升或(huo)下(xia)降(jiang)(jiang)速度(du)(du)在一定時間內發(fa)生變化(hua)。它(ta)需要(yao)平(ping)均(jun)溫(wen)(wen)(wen)升值(zhi)(zhi)或(huo)溫(wen)(wen)(wen)度(du)(du)降(jiang)(jiang)低值(zhi)(zhi)；例如，恒(heng)(heng)溫(wen)(wen)(wen)恒(heng)(heng)濕(shi)(shi)試(shi)驗(yan)箱在一定時間內的上(shang)升溫(wen)(wen)(wen)度(du)(du)該程度(du)(du)有(you)(you)(you)時為(wei)每分(fen)鐘(zhong)2度(du)(du)，有(you)(you)(you)時為(wei)每分(fen)鐘(zhong)3度(du)(du)，有(you)(you)(you)時為(wei)每分(fen)鐘(zhong)4分(fen)鐘(zhong)，但在此期間，平(ping)均(jun)為(wei)3度(du)(du)每分(fen)鐘(zhong)溫(wen)(wen)(wen)暖或(huo)冷卻。非(fei)線(xian)(xian)性意味著平(ping)均(jun)值(zhi)(zhi)為(wei)每分(fen)鐘(zhong)3度(du)(du)，并(bing)且會有(you)(you)(you)浮動(dong)。
