| 摘 要： | 连续曲率张力样条方法在最小曲率格网化方程中引入张力参数,可以消除最小曲率拟合曲面在已知数据点之间的区域存在的较大波动和无关变形点,张力参数的取值在区间0,1)。针对海面高数据,研究了张力参数取不同值的结果,得到了张力参数的最佳取值范围。

| Abstract: | Minimum-curvature surfaces may have large oscillations and extraneous inflection points.These extraneous inflection points can be eliminated by adding tension to the minimum-curvature gridding equation and the tension factor can be any data between 0,1）。The result of gridding sea surface height data using different tension parameters was discussed and the optimal range was given. |

| Keywords: | gridding continuous curvature splines in tension tension parameter |
