反射背景 meaning in Chinese

reflecting background

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
摘要塔河油田岩溶储集体（洞穴、礁滩、孔洞、裂缝或裂隙等）的地震波场特徵是弱反射背景之上的强弱不同的绕射波，因此，绕射波准确归位成像和振幅保持是研究岩溶储集体的基础。
