高低溫試驗箱升(sheng)降速率線性(xing)與非線性(xing)的區別(bie)

    通常，高(gao)低(di)溫(wen)(wen)(wen)試(shi)驗箱廠家生產的高(gao)低(di)溫(wen)(wen)(wen)箱分(fen)兩種(zhong)(zhong)升(sheng)降(jiang)(jiang)(jiang)(jiang)溫(wen)(wen)(wen)速(su)率(lv)(lv)。一(yi)種(zhong)(zhong)是全(quan)程(cheng)平均(jun)升(sheng)降(jiang)(jiang)(jiang)(jiang)溫(wen)(wen)(wen)速(su)度(du)（非線(xian)性），全(quan)程(cheng)平均(jun)速(su)度(du)是指(zhi)在試(shi)驗箱的變溫(wen)(wen)(wen)范(fan)圍內，zui高(gao)溫(wen)(wen)(wen)度(du)與zui低(di)溫(wen)(wen)(wen)度(du)這差值(zhi)與時間(jian)之比，指(zhi)的是整個高(gao)低(di)溫(wen)(wen)(wen)試(shi)驗箱升(sheng)降(jiang)(jiang)(jiang)(jiang)率(lv)(lv)大體一(yi)致(zhi)。另一(yi)種(zhong)(zhong)是全(quan)程(cheng)線(xian)形升(sheng)降(jiang)(jiang)(jiang)(jiang)速(su)率(lv)(lv)，是在試(shi)驗的某個時間(jian)段(duan)溫(wen)(wen)(wen)濕度(du)以一(yi)定的比率(lv)(lv)升(sheng)降(jiang)(jiang)(jiang)(jiang)。

     按(an)照行業設計(ji)方法，一(yi)般的(de)(de)(de)(de)高(gao)(gao)低(di)溫(wen)(wen)(wen)試驗箱溫(wen)(wen)(wen)度(du)升(sheng)(sheng)降變化都是(shi)全程(cheng)平(ping)均速(su)(su)(su)率(lv)，這樣可以(yi)提高(gao)(gao)設備的(de)(de)(de)(de)使用壽命，線(xian)形升(sheng)(sheng)降溫(wen)(wen)(wen)速(su)(su)(su)度(du)指的(de)(de)(de)(de)是(shi)在(zai)任(ren)意的(de)(de)(de)(de)一(yi)定時間(jian)段內，能夠保證的(de)(de)(de)(de)變溫(wen)(wen)(wen)速(su)(su)(su)率(lv)。而實際上(shang)是(shi)對于高(gao)(gao)低(di)溫(wen)(wen)(wen)試驗箱來說，保證線(xian)形升(sheng)(sheng)降溫(wen)(wen)(wen)速(su)(su)(su)度(du)的(de)(de)(de)(de)難度(du)zui大及zui關鍵的(de)(de)(de)(de)一(yi)段，是(shi)在(zai)降溫(wen)(wen)(wen)段后的(de)(de)(de)(de)一(yi)個(ge)5min的(de)(de)(de)(de)時間(jian)段內，試驗箱可以(yi)達到的(de)(de)(de)(de)降溫(wen)(wen)(wen)速(su)(su)(su)率(lv)。
