style="text-indent:25px">黑體溫度的概述：黑體溫度是物體內(nèi)分子間平均平動(dòng)動(dòng)能的一種表現(xiàn)形式。分子運(yùn)動(dòng)愈快，物體愈熱，即溫度愈低子運(yùn)動(dòng)愈慢，物體愈冷，即溫度愈低。從分子運(yùn)動(dòng)論觀點(diǎn)看，溫度是物體分子運(yùn)動(dòng)平均平動(dòng)動(dòng)能的標(biāo)志，溫度是分子熱運(yùn)動(dòng)的集體表現(xiàn)，含有統(tǒng)計(jì)意義。對(duì)于真空而言，溫度就表現(xiàn)為環(huán)境溫度，是物體在該真空環(huán)境下，物體內(nèi)分子間平均動(dòng)能的一種表現(xiàn)形式。物體在不同熱源輻射下的不同真空里，物體的溫度是不同的，這一現(xiàn)象為真空環(huán)境溫度。比如，物體在離太陽(yáng)較近的太空中，溫度較高；物體在離太陽(yáng)較遠(yuǎn)的太空中，反之，溫度較低。這是太陽(yáng)輻射對(duì)太空環(huán)境溫度的影響。</p><p> 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(guò)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(shí)，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(gè)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(jì)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(zhǎng)處，當(dāng)量溫度為302.01℃；?5μm當(dāng)量溫度為300.18℃；隨著波長(zhǎng)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(shí)（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(zhǎng)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(jì)，只要等溫黑體工作正常，因工作波長(zhǎng)的不同所帶來(lái)輻射溫度測(cè)量的差異，完全可以忽略不計(jì)。
