2 . it simplified the tlp as vertical floating arrays , did some work about second - order nonlinear diffraction wave force on tlp 2 .將結構簡化為直立浮筒柱群,研究了平臺本體上波浪的二階非線性繞射問題。
In this report , mathematical models for combined refraction - diffraction waves in water of slowly varying topography are presented 本報告主要沿著適宜于中、小尺度空間的緩變水深水域波浪傳播的數學模型這條主線,對近岸水域中波浪的傳播進行研究。
And the interactive influence of the coaxial diffraction wave components during reconstruction can be eliminated completely by phase - shifting method . this in - line phase - shifting digital holography has been applied to three dimensional microscopy , non - contact measurement , pattern recognition and surface contouring 這種同軸相移數字全息技術,可以廣泛應用于小尺度三維形貌的快速測量、數字無損干涉計量、圖像識別、顯微成像等領域。
This method has some characters : during recording of the transmissive holograms the holographic grating placed in front of the holographic plate closefittingly is used as a spectroscope . the transmissive wave is served as the object wave and the diffraction wave through the holographic grating or the deflective reflect wave produced by the silicon slice is served as the reference wave , therefore the hologram is named as self - reference image hologram . the recording results are the off - axis holograms and the twin images can be separated successfully 在記錄透射型全息圖時,將全息光柵緊貼置于記錄干板之前,而光柵起到了分光的作用,直透波作為全息圖的物光波,參考光是物光通過光柵后產生的衍射波;記錄反射型全息圖時將硅片置于記錄干板之后,利用反射硅片產生離軸參考光,因此系統僅需一束照明光束,參考光來自物光本身,因此稱之為自參考像全息圖。
Seismic wave field feature of ordovician carbonate karst reservoir ( cave , reef , hole , crack and cranny ) in tahe oil field is the difference magnitude diffraction wave over weak reflection amplitude , so , the diffraction wave exact imaging and fidelity amplitude processing is the basic of carbonate karst reservoir study 摘要塔河油田巖溶儲集體(洞穴、礁灘、孔洞、裂縫或裂隙等)的地震波場特徵是弱反射背景之上的強弱不同的繞射波,因此,繞射波準確歸位成像和振幅保持是研究巖溶儲集體的基礎。
