实际算例表明，最优采样频率点位置并不依赖于系统的输出，仅仅取决于激励的性质。

The actual computation example shows that the optimal sampling frequency locations are found to be independent of the system response, and solely depend on the nature of the excitation.

本文提出一种直接在点采样曲面上计算曲面的高斯曲率、平均曲率及主曲率等局部微分性质的方法。

An approach is proposed to estimate several differential properties, including Gaussian curvature, mean curvature and main curvature on point-sampled surfaces in presence of noise.
