采用上述辅助定位后如遇椎弓根部穿破情况则需要手动调整螺钉以使螺钉刚好与原穿破侧椎弓根骨壁相切。 1.2.5创建下侧进钉方向的椎弓根螺钉模型：在AutoCAD2006程序中将椎弓根螺钉内外夹角、上方夹角两等分，由同侧两等分点与椎弓根中心点共同创建一平面，依该平面与同侧球在下终板平面交点创建下方螺钉模型。

This optimal allocation yields the highest level of utility (at point C , the tangency of the capital allocation line and the highest indifference curve).

该最优配置使得投资者效用最大化（在 CAL 线和无差异曲线的相切处 C 点达到）。
