在自然界中，當(dāng)物體的溫度高于零度時，由于它內(nèi)部熱運(yùn)動的存在，就會不斷的向四周輻射電磁波，其中就包含了波段位于0.75μm~100μm的紅外線。他比較大的特點(diǎn)是在給定的溫度和波長下，物體發(fā)射的輻射能有一個比較大值，這種物質(zhì)稱為黑體，并設(shè)定他的反射系數(shù)為1，其他的物質(zhì)反射系數(shù)小于1，稱為灰體，由于黑體的光譜輻射功率P(λＴ)與jue dui溫度T之間滿足普朗克定。說明在jue dui溫度T下，波長λ處單位面積上黑體的輻射功率為P(λＴ)。上海人體測溫黑體爐供應(yīng)</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/2965640.html</p></div></div></div></div></div><div id="gfc8gxw"
