| 摘 要： | 通过编写飞机舱温数据处理与分析软件平台,对有关文献的舱温实测数据处理方法进行考核研究,结果表明：要使得到的样条逼近函数的误差最小,应合理选取自变量取值范围的分段数和样条次数。如若不然,在样条次数相同的情况下,分段计算得到样条逼近函数的误差可能要比在整个区间上不分段时得到的误差大。

| 关 键 词： | 舱温 数据预处理 样条函数 误差 分段数 样条次数 |

| Abstract: | The research on data processing method of aircraft cabin temperature in related literature was checked by compiling the processing and analyzing software platform of aircraft cabin temperature.The results show that piecewise number in independent variable span and spline order number should be selected appropriately in order to obtain the minimum error of spline approximating function.If the piecewise number and spline order number are not selected appropriately,the error of spline approximating function with piecewise treatment may be bigger than that without piecewise treatment in whole span when the spline order numbers are same for both two conditions. |
