曲线数据处理之曲线插值主要内容：实际观测值总不能稠密到满足任何条件下的需求，对中间没有观测值的点位则需要通过插值获得答案。又实际观测数据往往是离散的，即在X轴上观测数据点之间是不等距的，也需要通过插值使其等距化。-curve data processing for curve interpolation main elements : the actual observed values can not be populated any conditions to meet the needs of the middle of no observation point interpolation is needed to be answered. Practical observation data is often separated, in the X axis between observational data is not offset the need to make it through the interpolation of equidistance.
