衍射損失 的英文怎麼說
中文拼音 [yǎnshèsǔnshī]
衍射損失
英文
diffraction loss-
The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take - off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. the neutron flux at different wavelength, under different reflection and take - off angle of the monochromator and divergency of the first collimator, were given. the simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected
用蒙特卡羅模擬方法對中子應力衍射譜儀的設計方案進行了優化研究，提出了一系列可供參考的數據：確定了單色器的位置、尺寸、垂直聚焦單色器在不同起飛角下的聚焦曲率半徑和傾角；討論了第二準直器的尺寸和發散，以及使用第二準直器造成的強度損失；給出了在不同單色器反射面、起飛角、中子波長和第一準直器發散度的情況下樣品處的中子注量率，以及多種組合情況下譜儀的解析度曲線；對限束方孔的尺寸、距離樣品遠近對強度損失和測量中的影響做了深入研究。More recent studies show nanowires products with narrow dismeter distribution around 5 - 10mn and lengths ranging from several hundred nanometers to several micrometers can be obtained if the mixture solution of naoh and koh was replaced by koh solution. the nanowires were analyzed by a range of methods including powder x - ray diffraction ( xrd ), high resolution electron microscopy ( hrem ), selected area electron diffraction ( saed ), electron energy loss spectroscopy ( eels ), xrd and hrem image simulations. the structure of nanowires is determinded to be of the type of k2ti6oi3
利用x射線衍射（ xri ） ） 、高分辨電子顯微鏡（ hrtem ） 、選區電子衍射（ saed ） 、電子能量損失譜（ eels ）以及x射線衍射和高分辨像模擬等分析測試手段，初步分析了這種納米線的生長機理，探討了她的結構和光學性能，實驗結果顯示這種納米線具有kzti6o ; 3的結構，紫外一可見光吸收光譜顯示， kzti6ol3納米線禁帶寬度約為3 . 45ev 。Used as ring - down cavity, this stable resonator has, firstly, more influence of misalignment of cavity mirrors on its measured reflectivity, but less of length misadjustment ; secondly, shorter cavity length which advantageous in engineering ; finally, less diffraction loss and thus higher metrical precision
結果表明，這種穩定腔用作衰蕩腔，測量結果受腔鏡角度失調影響較大，而受腔長失調影響小；其長度較短，便於工程應用；衍射損耗較小，測量精度高。
