求翻译：本文每3个节点取一个采样点，同时为保证数据长度的一致性，这里对采样点的数据进行三次样条差值，共得到1513个数据点，以研究该方法对传感器布置的敏感性。是什么意思？

This article every 3 nodes from a sampling point, at the same time to ensure consistency of data length of the sampling points here, the data section as margin, 3 times a total 1513 data point by the way, in order to study the sensitivity of sensor deployment.

The this article every 3 nodes take a sampling point, simultaneously for the guarantee data length uniformity, here carries on three transect interpolations to the sampling point data, altogether obtains 1513 data points, studies this method the sensitivity which arranges to the sensor.

This article every 3 nodes from one sampling point, at the same time to ensure the consistency of the data length, here on the sample point data to cubic spline difference, total 1513 for a data point to study the sensitivity of the method to sensor placement.
