2、在波長—定情況下，沒有物體能夠比同溫度的黑體發(fā)射更多的能量； </p> <p> 3、黑體為—個漫發(fā)射體。 </p> </p> <p> 黑體輻射源主要由黑體空腔、黑體空腔測溫、控溫元件或系統、保溫層及外殼等組成。常用的黑體空腔形狀有圓柱形、圓錐形、球形、圓柱加圓錐形、圓柱加倒錐形以及其他形狀；黑體空腔測溫和控溫元件可以是電阻溫度計或熱電偶溫度計；控溫系統可采用熱管法、恒溫液流法、電阻加熱法等。 </p><p> 黑體的輻射能量 </p> <p> 物體的輻射出射度M(T)和吸收本領α的比值M/α與物體的性質無關，等于同一溫度下黑體的輻射出射度M0(T)。其表明，吸收本領大的物體，其發(fā)射本領大，如果該物體不能發(fā)射某一波長的輻射能，也決不能吸收此波長的輻射能。實驗表明，實際物體的輻射度除了依賴于溫度和波長外，還與構成該物體的材料性質及表面狀態(tài)等因素有關。這里，我們引入一個隨材料性質及表面狀態(tài)變化的輻射系數，則就可把黑體的基本定律應用于實際物體。這個輻射系數，就是常說的發(fā)射率，或稱之為比輻射率，其定義為實際物體與同溫度黑體輻射性能之比。面源黑體爐如何加黑體標靶使用。</p><div

輻射溫度校準：是通過一個非接觸式的高精細度標準傳遞源對輻射腔體的溫度進行測量，使用的發(fā)射率為1。輻射源的溫度刻度被調整到高溫計所測量的溫度值。在規(guī)定的光譜范圍內，輻射源的發(fā)射率為1（有例外情況：傳遞標準高溫度計的發(fā)射率設置成小于1，這個設置也是黑體校準源的有效發(fā)射率，因此小于1） </p> <p> 接觸式溫度計校準：校準源通過一個內置的高精度熱電偶（或鉑電阻）測量并顯示溫度，在輻射腔體上開一個孔，通過一個經過校準的探針來進行測量。高精度低溫面源黑體的研究。上海熱成像面源黑體爐</p><p style="text-indent:25px">紅外熱像儀黑體輻射源測溫標定**監(jiān)測黑體面源輻射。上海熱成像面源黑體爐</p><p> 什么是紅外線： </p> <p>
