自從美國在越南武裝前面使用紅外技術(shù)，成功地偵察到密林中的胡志明小道后（注：當(dāng)時(shí)胡志明小道是運(yùn)輸線），拉開了紅外技術(shù)在武裝上應(yīng)用的序幕。隨后，各國都開展了紅外偵察、紅外偽裝、紅外制導(dǎo)、紅外誘餌、空中防衛(wèi)等技術(shù)的研究工作，這就促進(jìn)了對(duì)黑體技術(shù)的研究，尤其是對(duì)中低溫黑體的研究。因此國外在20世紀(jì)80年代就已經(jīng)有低溫黑體，我國對(duì)低溫黑體的研究，是從20世紀(jì)90開始。近30年來，紅外技術(shù)已經(jīng)很廣地應(yīng)用于民用，如紅外資源衛(wèi)星、紅外氣象衛(wèi)星、紅外加熱、紅外干燥、醫(yī)用紅外、醫(yī)用額溫槍、紅外測溫等，同時(shí)開始了民用黑體產(chǎn)品的研究。尤其是近20年來，紅外溫度計(jì)的很廣應(yīng)用，作為紅外溫度計(jì)檢定用的主要設(shè)備－黑體的市場需求量增加，這促進(jìn)了黑體技術(shù)向產(chǎn)品化傳化的進(jìn)度。對(duì)黑體技術(shù)的研究，尤其是對(duì)黑體發(fā)射率技術(shù)的研制，從20世紀(jì)50年代開始，一直是斷斷續(xù)續(xù)地進(jìn)行著。國內(nèi)一些大學(xué)，對(duì)黑體發(fā)射率進(jìn)行研究，并根據(jù)輻射換熱原理，對(duì)當(dāng)時(shí)的黑體產(chǎn)品研究出一套發(fā)射率的計(jì)算方法。同時(shí)，形成了對(duì)圓柱形黑體腔，腔體長度和腔口之比（稱為形腔比）為一個(gè)固定的模式。上海黑體爐系列黑體爐的生產(chǎn)廠家：上海蕓尖智能科技有限公司。</p><div

radiationsource能發(fā)射電離輻射的物質(zhì)或裝置。從廣義上講，凡能釋放各種電離輻射的物質(zhì)或裝置(如宇宙射線)均可視為輻射源。但習(xí)慣上用于γ探傷、放射和輻射加工等的放射性深度較高的放射源稱為輻射源。黑體爐是如何校準(zhǔn)的？上海熱成像黑體爐</p><p
