譜線黑度 的英文怎麼說
中文拼音 [pǔxiànhēidù]
譜線黑度
英文
blackness of spectral line-
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 composite roll of high speed steel has the synthetical life of over ten times more than traditional high cr cast iron roll. now the research and production of the high speed steel for roll are very drastic. in this thesis, the microstructure, heat treatment and performance of high speed steel fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w ( wt ) are studied systematically by using metallograph, method of lattice, xrd, sem, eds and hardness
本文利用金相法（包括黑白金相和彩色金相） 、 x射線衍射（ xrd ） 、掃描電子顯微鏡（ sem ） 、能譜（ eds ）及洛氏硬度分析儀等手段，對復合軋輥用高速鋼fe - 2 c - 4 v - 4 mo - 5 cr - x w （其它部分如未作特殊註明均為質量分數）合金系的顯微組織、熱處理工藝及性能進行了系統地分析。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Studies show that, in a binary system, huge energy is released when matter of companion star fall onto the surface of neutron star. on the contrary, when matter falls into black hole, it together with the energy generated will disappear behind the event horizon. for that reason, x rays emitted by neutron star binaries are stronger and their spectra exhibit special characteristics
研究發現，在雙星系統中，伴星的物質掉落中子星的表面時會釋放巨大能量，而物質掉落黑洞時，則會與它所擁有能量一同消失於視界之中因此含有中子星的雙星系統所發出的x射線強度總是較高，而光譜也有不同的特徵。分享友人
