For single vug,when the lateral scale of vug is smaller than Fresnel radius,and the vertical scale is smaller than tuning thickness,the reflection amplitude of vug is proportional to its scale. For carbonate reservoir with random arranged vug,seismic wave amplitude is proportional to vug density.Key words random medium;forward modeling;carbonate;vug

对于单个的溶洞而言，当溶洞横向尺度小于菲涅尔带半径，纵向尺度小于调谐厚度时，溶洞反射振幅与溶洞尺度成正比例关系；对于随机分布孔洞的碳酸盐岩储层而言，地震波能量与孔洞密度成正比例关系。

Each of cores were carried on NMR measurement after each of six or seven different centrifugal force, author can got that 200 psi was suitable to be best centrifugal force calibrating T_2 cutoff value for glutenite cores, and 400 psi was suitable for carbonatite and vulcanite cores in this ***, and corresponding lower limit of valid throat is 0.1μm for glutenite and 0.05μm for carbonatite and vulcanite.

The study results indicate that as emission power increases, the peak power density on the section of a certain distance will increase firstly, then it will descend and that the peak light intensity on the section will increase with the increasing of spot radius of basic mode Gaussian beam. As the propagation distance increases, the peak light intensity on the section will descend gradually, and the laser energy will spread. The light intensity distribution exhibits straw hat shape on a certain conditions, in other word to say, the central light intensity is less than acroteric light intensity.

结果表明，无风稳态热晕效应存在时，随发射功率的增大，一定传输距离截面上的峰值功率密度先增人后减小；截面上的峰值光强随基模高斯光束的腰斑半径的增大而增大；随着传输距离的增大，截面上峰值光强在逐渐减小，能量在逐渐向周围扩展；在一定条件下，截面上的光强分布会呈现中心光强小于周围光强的&草帽型&分布。
