| 摘 要： | 运用Matlab语言对4125A柴油机调速特性试验数据进行处理，通过建立数学模型，编制程序描点法绘出数据图，得出最初的描点图，采用最小二乘分段多项式拟合法进行曲线拟合，得出较为完善的曲线图，对拟合前后的曲线进行了对比，证明Matlab的数据处理功能和绘图功能以及分段多项式拟合法的精确可靠。

| Abstract: | Test data of governor control characteristics for 4125A diesel engine was processed through Matlab. Initial tracing spot dia- gram was obtained through tracing method based on mathematical model, and integrity graph was drawn by least square polynomial fit- ting. Graphs were contrasted before and after curve fitting, therefore precision and reliability of data processing and polynomial fitting with Matlab proposed this paper was feasible. |
