黑體輻射光譜
英文
blackbody radiation spectrum-
The spectral distribution of a black body radiation is described by planck's.
黑體輻射的光譜分配由普朗克定律描述。Black body spectrum
黑體輻射光譜In this method of measuring temperature, when the measuring results of time - resolved spectrum have been completed, computing the fit spectrum of corresponding planck bold - radiation with least duple multiply theory, the temperature is measured
溫度擬合方法的主要思想：獲得光譜的時間分辨測量結果后，用最小二乘法原理計算熱輻射譜（主要在可見光區）擬合得到相應普朗克黑體輻射加線，並解析其溫度。The next move is to deduce the range of a bombing radiating wavelength with the flying bomb ' s temperature being analyzed and to compute the target ' s irradiance and radiated luminance between spectral penetrating strip based on the planck formula for the black body
在此基礎上，從分析飛行彈體的爆炸溫度出發，推導了彈體爆炸時輻射峰值波長的范圍，分析了黑體輻射的普朗克公式，計算出目標在光譜通帶內的輻出度和輻射亮度。As explained by the following figure, gas in low pressure and low density will alter the light that passes through it. it is because the gas will absorb light at some particular wavelengths and re - radiate it in random directions. thus, after passing through the low pressure gas, the spectrum of the original white light will have dark lines, called
並不是所有光譜都是黑體輻射光譜，如下圖所示，低壓下的低密度氣體會改變通過它們的光線，這是由於氣體會吸收特定波長的光波並隨機向不同方向把所吸收的光線輻射出來，結果光線在通過低壓氣體后，原本的光譜上會出現很多稱為Blackbody spectral radiant emittance
黑體光譜輻射密度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。Research on measurement of spectral radiance luminance base on hightemperature blackbody
基於高溫黑體的光譜輻射亮度的測試研究Blackbody radiation spectrum
黑體輻射光譜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。分享友人
