透射放映 的英文怎麼說
中文拼音 [tòushèfàngyìng]
透射放映
英文
diascopic projection-
An inverted image is formed in the first image plane and the three subsequent lenses in the namely the diffraction lens, the intermediate lens and the projector lens are used either to magnify this image or to magnify the diffraction pattern
在第一映象平面出現一個倒的圖象，隨后的第三透鏡也就是衍射透鏡，中間的透鏡和投影透鏡被用來放大圖象或者放大衍射模式。The variation of the film composition can be monitored by using the method of spectrum analysis during the film deposition ( for the intensity of the persistent line is proportional to the particle density of the element in the vacuum chamber ). the measurement of the transmission spectrum of the film on a transparent substrate can be used to calculate the film parameters, such as refractive index, extinction coefficient and the thickness of the film. therefore, the combination of the two methods would be helpful to on line monitoring the film constituents and the optical paramenters in the preparation of thin films
在制備薄膜的過程中，利用光譜分析的方法，以放電光譜特徵譜線強度的變化來反映相應物質成分的變化，以連續光譜光源發出的光透射過薄膜的透射率的變化，來反映薄膜的厚度、折射率、吸收系數等光學參數的變化，從而達到在制膜過程中，對薄膜的成分、厚度等參數進行在線監控的目的The reflective and transmitting projection screens
反射和透射放映銀幕The transmitting projection screens
透射放映銀幕As mentioned above, to image the diffraction pattern it is necessary to reduce the power of the diffraction lens by altering the current through the lens coils from the value used to form an enlarged image of the first image
如上所言，要成像衍射模型就必須縮減衍射透鏡的能量，通過改變從已有形態到形成第一映像的放大映像過程中穿過透鏡圈的能量實現。As digital signals are more robust than analogue ones, consumers would be able to get much better sound and picture quality through dtv. in addition, dtv enables the provision of high definition television ( hdtv ) which delivers cinema - quality pictures and cd - quality sound
由於數碼訊號較模擬訊號強，消費者可透過數碼電視收到質素更佳的聲音及畫面。此外，數碼電視有助高解像電視的播放；高解像電視所提供的畫面質素可媲美電影院的放映效果，音質達到鐳射唱片的水準。分享友人
