摘要
针对公路试验数据处理中手工作图误差大、精度低的特点,采用最小二乘法原理对试验数据进行拟合并且通过计算机作图,不仅方便地实现了作图的自动化,而且提高了作图精度。
Due to the diagram-making by hand with more errors and less precision in data processing of highway tests,, the method of least square is used for processing curve fitting and the diagram is processed by computer, so it can not only realize to make the automation of the diagram expediently, but also increase the accuracy.
