At last, the conclusions of the whole thesis are drawn, and it is put forward that the future research emphases on the infrared radiation absorption ct technology should focus on : instantly get the absorption projections are the crucial factor to utilize the technology industrially ; on the basis of the hypothesis that the gas is ideal gas, species concentration of particular gas medium can be measured at the same time, which must be helpful to comprehend combustion essence ; if laser source to replaces blackbody stove, for irradiant flame, interferometric projection can be attained, and its temperature distribution will known
最後，對全文進行了總結，並指出今後研究工作重點。指出：瞬時得到各方向的投影是此技術實用化關鍵；在獲得溫度分佈信息基礎上，進行必要的假設和推導，能同時得到火焰中某特定組分濃度的分佈，這必將進一步我們對燃燒本質的理解；利用方向性好，輻射強度高的激光源代替常規的黑體爐，能得到輻射干涉投影圖像，這樣就能測量所介紹系統不能測量的發光火焰溫度分佈。 -

The approach is that we first calibrate the filter radiometer with cryogenic radiometer and measurement equipment of relative spectral responsivity and then calculate the absolute spectral responsivity. because the drift in blackbody temperature directly influnces measurement accuracy, so we adopt a feedback system to stabilize blackbody temperature through controlling the current of blackbody that improves measurement accuracy greatly
該方法首先要用低溫輻射計及相對光譜響應度測量裝置對濾光輻射計進行標定，經計算可得到濾光輻射計的絕對光譜響應度；由於黑體溫度的漂移直接影響到測量精度，我們採用反饋系統通過控制黑體的加熱電流，來穩定黑體溫度。 -
The measurement system is made up of optical system, comparison system, control system and cooling system in the course of the temperature measurement of high temperature blackbody, we use filter radiometer that is a new approach to measure radiation temperature. the approach was adopted by ptb, npl and vniiofo in 1997 when they made international comparisions of spectral irradiance
在測量高溫黑體溫度的過程中，使用了新型的輻射測溫法，濾光輻射計測量方法，該方法在1997年光譜輻照度國際比對時被ptb 、 npl 、 vn ofo等國家所採用，並得到一致認可。 -
Blackbody equivalent temperature
黑體等效溫度 -
Microwave radiation was detected from all directions in the sky. later on, scientists realized that the origin of this radiation is cosmological. the spectrum matches with that emitted by a blackbody of temperature 3k
1965年，科學家發現天空任何方向皆可偵測到微波，這是一個重要的天文發現，但研究員卻懵然不知，后來才知道這些微波來自宇宙，而這些輻射的光譜對應于絕對溫度為3k的黑體輻射。
