| 摘 要： | 提取试验数据的上下包络,可以在总体上对试验数据进行初步分析,掌握试验数据的有效程度.借鉴EMD方法中的镜像延拓法对试验数据边界进行对称处理,选取三次样条函数进行插值以提取试验数据上下包络.数据处理结果表明,这种方法可以有效地提取试验数据的上下包络.

| Abstract: | The significant degree of the test data is obtained by picking the envelop,which can be analyzed as a whole.It is possible to draw lesson from the empirical Mode Decomposition(EMD) method and process test data to get the envelop by using the mirror extension and cubic spline interpolation.The data-processing results indicate that the method in this paper can be used to pick the test data of the envelop well. |
