With the force measuring system, the milling force is measured, and the experiential formula for calculating milling force is obtained with the method of linearity regression. 通过测力系统测量铣削力,用线性回归方法对实验数据进行分析,得出铣削力经验公式,并验证了公式在实验参数范围内的有效性。
This finding bolsters the so-called gestural theory of language evolution, whose proponents argue that language evolved initially as a gesture system before becoming vocal. 这项发现支持了语言演化的肢体理论,提倡这理论的人认为语言最初是从动作系统开始,后来才发展出语音系统。
