The formula is derived from the analysis of a non- relativistic configuration-interaction plus core polarization （CICP） calculation of the tune-out wavelengths for rubidium. The differences between the wavelengths predicted from the approximation formula and the exact CICP calculation are at the 10-3 nm level. The predicted five longest tune-out wavelengths are 790.115nm, 423.155nm, 421.111 nm, 359.429nm, and 359.022nm, respectively.展开更多

Based on reprocessed high-resolution seismic data, the forward model was investigated. Under the guidance of model combining with well data in the research area, the methodology of recognizing DHS pinch-out was discussed in detail. The result is helpful for the research of DHS pinch-out reservoirs in Tarim basin and for the exploration of this type of reservoir in China.展开更多
