- The first Fresnel zone radius can be treated as lateral resolving power of seismic data approximately.
可以将第一菲涅尔带半径作为地震资料横向分辨力的一种近似。 - Common reflection surface ( CRS) stack concerns the local feature of the reflector and all reflection response within the first Fresnel zone, so it fully use the potential of the multiple coverage seismic data.
共反射面元（CRS）叠加考虑了反射层的局部特征和第一菲涅耳带内的全部反射，更充分挖掘了多次覆盖数据的潜力。 - Also discussed the issue on the resolution of seismic waves, through a variety of models of different sizes to verify the seismic waves on the vertical resolution of horizontal resolution and the theory of the first Fresnel zone deepened understanding of the theory.
同时讨论了关于地震波分辨率的问题，通过多种不同尺寸的模型，验证了关于地震波水平分辨率和纵向分辨率的理论，加深了对第一菲涅尔带理论的理解。 - It is generally recognized that the vertical resolution is the tuning thickness "quarter wavelength", the horizontal resolution is the first Fresnel zone radius.
金属矿地震勘探中的分辨率分为垂直分辨率和水平分辨率，一般认为垂直分辨率为调谐厚度&四分之一波长，水平分辨率为第一菲涅尔带半径。
