| 摘 要： | 将５次Ｂ样条函数和２阶Ｈｅｒｍｉｔｅ函数联合使用，建立了广义参数５次有限条元的位移场函数，算例表明，这种半解析高阶有限样条元不仅保持了普通高阶条元的优点，并且可以将５次条元推广应用于变截面，变刚度等曲率不连续结构中。

| Abstract: | his paper proposed a new kind of high order finite strip with the help of quintic B-spline functions and quintic Hermit functions.The example in this paper shows that this new kind of finite strip not only keeps the merits of the common one,but also can be used in variable thickness or stiffness plates which the curvity are uncontinuous. |

| Keywords: | finite strip spline functions Hermite function |
