摘要
文中通过几种规则曲线的插值拟合实验,具体分析了拟合误差的大小和影响规律;提出了在构建曲线的不确定模型时除考虑端点误差的影响外,还应考虑曲线拟合误差的影响。考虑到上述两种误差在两采样点之间的影响规律正好相反,文中建议对于一般曲线的不确定模型采用传统的ε带较好。
Based on the interpolating fitting experiment of several regular curves the degree of fitting error and its law of influenceis analyzed. When establishing the undeteministic model of curve, not only the influence of edppoint error, but also the fitting error of curveshould be considered. As the law of influence of the above two errors atthe two samling points are on the contrary, it is suggested to use the traditional x band for the undeterministic model of the general curve
