注意事項(xiàng)一：黑體爐的溫度上限值不可長時間使用，否則會造成爐膛被燒壞！應(yīng)該保留10%～15%的余量。 </p> <p> 注意事項(xiàng)二：高溫黑體爐升溫后，需要散熱降溫。使用完畢后，不可盲目切斷黑體爐的供電。否則會造成散熱受阻，儀器被燒壞！應(yīng)該先關(guān)閉黑體爐本機(jī)電源或者把黑體爐溫度設(shè)置為0（但是風(fēng)扇仍然在運(yùn)轉(zhuǎn)）一段時間后，上海黑體爐校準(zhǔn)規(guī)范，黑體爐顯示溫度為200℃以下時，確認(rèn)風(fēng)扇停止運(yùn)轉(zhuǎn)后，再關(guān)閉總電源?。ǖ蜏丶俺睾隗w爐風(fēng)扇可能不會啟動!） </p> <p> 注意事項(xiàng)三：黑體腔輻射表面涂有昂貴的黑體漆，請不要用手指等試圖直接擦拭，否則會造成黑體腔輻射表面受污染，輻射率下降。 </p> <p> 注意事項(xiàng)四：在黑體爐工作的時候一定不要去觸碰其表面的紅外目標(biāo)源。紅外目標(biāo)源上表面的溫度都會在顯示器上顯示出來，上海黑體爐校準(zhǔn)規(guī)范，它實(shí)際的溫度和顯示溫度是一樣的，上海黑體爐校準(zhǔn)規(guī)范，假如，黑體爐設(shè)置的溫度為200℃，那么黑體靶心的位置的溫度就是200℃，而在其周圍區(qū)域的溫度也非常高，如果觸碰其表面，就會很容易使自己燒傷; </p> <p> 注意事項(xiàng)五如果在沒有正確的連接黑體爐電源線的時候，請不要立即開啟或者操作黑體爐，請讓專業(yè)人員檢查后方可繼續(xù)使用。 </p> <p> <br /> 中溫黑體爐的發(fā)射率是多少？上海黑體爐校準(zhǔn)規(guī)范</p><div style="width:100%;text-align: center;"><img

什么是等溫黑體：等溫黑體本身已經(jīng)形成空腔，腔體內(nèi)表面發(fā)射率的已經(jīng)經(jīng)過特殊工藝處理均勻一致，溫度均勻性也好。假定等溫黑體空腔內(nèi)溫度不均勻時，情況又如何 </p> <p> 呢？下面進(jìn)行詳細(xì)的理論分析。 </p> <p> 將園柱形空腔分為3個區(qū)域，腔底、腔口和腔壁。這里假設(shè)比較大溫度差異為20～40℃，其計算結(jié)果為平均溫度為300℃（腔內(nèi)極限溫差為20℃），在0.665μm波長處，當(dāng)量溫度為302.01℃；?5μm當(dāng)量溫度為300.18℃；隨著波長的增加，當(dāng)量溫度基本等于算術(shù)加權(quán)平均值300℃。在平均溫度1100℃時（溫度差異40℃），0.665μm的當(dāng)量溫度為1101.3℃，與平均溫度差1.3℃；0.8μm以后，當(dāng)量溫度基本為1100℃，與平均溫度已經(jīng)接近。上海蕓尖智能科技公司黑體爐均為等溫黑體空腔，溫度均勻性很好，等溫黑體溫度腔內(nèi)溫度差異很小。腔口發(fā)射能隨波長分布均勻，完全可以看作光譜輻射能量符合普朗克定律。用等溫黑體檢定輻射溫度計，只要等溫黑體工作正常，因工作波長的不同所帶來輻射溫度測量的差異，完全可以忽略不計。
