    Abstract: The present disclosure relates to the technical field of medical supplies, in particular to a fusion cage. The fusion cage comprises a main body, which is a flat-shaped porous structural body and composed of a plurality of structural units. The fusion cage provided by the present disclosure is the flat-shaped porous structural body composed of the plurality of structural units, the porosity of the whole structure of the fusion cage is controlled by using the parametrization design, so the elastic modulus of a fusion body is effectively reduced, and then each structural unit comprises the basal body and the plurality of extension portions extending from the surface of the basal body, the surfaces of the basal body and/or the extension portions are composed of the plurality of curved surfaces through smooth connection, and such design effectively reduces the problem of stress concentration, and improving the postoperative recovery effect of patients.

    Abstract: Disclosed is a quantitative identification method of standard chart for shale lithofacies prediction, and relates to the field of shale oil and gas exploration and development. On the basis of logging data, the application designs the discrimination standard of shale lithofacies chart, maximizes the utilization of different types of logging curves, extracts characteristic logging curves, and constructs the identification system of typical lithofacies from two angles of absolute value and relative value of logging curves, thus avoiding the waste of original data sources and subjective errors in the identification process, finally realizing the identification of characteristic logging curves of typical shale lithofacies, and being beneficial to the subsequent research on spatial distribution of shale lithofacies facing the regional research area.
