n.齿状；齿状突起
Aurelian gold yellow, millimeter of body length 9-12, two side provide abdomen dentation. 蛹金黄色,体长9-12毫米,腹部两侧具齿状突起。
This is a widespread species variable in the shape, size, and marginal dentation of the leaf blades. 这是一在形状，尺寸和叶片的边缘的牙齿里易变的广布的种。
In case that the camshaft signal measured by the first falling edge after dentation is low, then the following TDC would be of the first cylinder. 若缺齿后第一个下降沿检测到凸轮信号为低，则接下来的TDC是一缸TDC。
Unlike the conventional hardness test. in the moving in dentation test there is a displacement of object perpendicalar fo the direction of load. 与传统的硬度实验方法不同的是，在进行刻划硬度实验时，被测物体在与载荷垂直方向上发生位移。
