Curve functions of axial buccal crown and gingiva contour of each section were acquired by means of curve fitting, and the angle of emergence pofile was calculated, which represents the degree of undercut. Results There is unique relationship between axial crown and gingiva contour individually. This character of tooth is similar to its contralateral tooth.

结果 不同个体的牙冠轴面外形和牙龈外形有其特定的几何关系，同一断面的牙冠轴面外形曲线对应特定的牙龈外形曲线；同名牙同一断面的牙冠轴面外形之间及牙龈外形之间的重叠性很好。

Three cross-sections were made through crown and gingiva of the model tooth. Curve functions of axial buccal crown and gingiva contour of each section were acquired by means of curve fitting, and the angle of emergence pofile was calculated, which represents the degree of undercut.

以下颌第二前磨牙为研究对象，在牙列模型上通过牙冠部、牙龈作3个纵断面，用曲线拟和的方法得到每个断面的牙齿轴面外形及相应牙龈外形的曲线方程，以此分析两者之间的关系并计算牙冠起始外形角度，即倒凹程度的大小。

Indian manufacturers scratch their heads in bafflement at China's ability to undercut them.

印度的制造商对为什么中国能抢他们的生意感到百思不得其解。

C chimeric side slider structure is made to undercut handled.

From the original signal of"ladder type" undercut, it is difficult to find out the exception, through observing the undercut signal by means of the"focalizing scanning"of wavelet transform in time-frequency domain, the fault features are accurately extracted. The results reveal that this method has flexibility to the variation of tool diameters, tooth of cutter and cutting parameters.

在&阶梯型&过切的原始信号上几乎看不出信号有明显异常现象，在时频空间采用小波分析方法&聚焦式&扫描观察&阶梯型&过切信息，能准确地提取过切的故障特征，研究表明，该方法对刀具直径、刀具齿数及切削参数的改变有较强的适应性。

But, undercut technology may deteriorate the stresss concentration. In order to improve the situation, for a crank throw of a given ductile iron crankshaft, finite element analysis is conducted. The analysis result is optimized and related fatigue calculation is carried out. A compare between calculation and test results is performed and compared results show that conculation result is reliable. Therefore a good undercut structure is found and the reliability of crankshaft is improved.

球铁曲轴加沉割槽往往会加大曲轴的应力集中，根据某厂设计的球铁曲轴，本论文利用有限元分析的方法，对其单拐曲轴的沉割槽进行有限元模拟分析，在分析结果的基础上进行优化设计，最后得出较好的沉割槽结构，从而得到较好沉割结构，提高曲轴的可靠性。

Take the spectators' jack and put it in the deck face-down in the bottom half of the deck. Get a thumb-break under the top card and execute a double-undercut, which gets it on the bottom. Make sure that in the double-undercut when you cut the deck you're cutting in the face-down part.

紧随其后，再用一次slip-cut把顶上的那一张Jack也弄到下半段面向上的牌中，然后用右手把上一小半段面向下的正常杂牌放到桌上（不能拿太多，以免漏出那些面向上的牌而穿帮），然后对观众谎说您选的那张Jack现在已经在那小半段正常杂牌的顶上了并让他们翻开那张顶牌，但他们会发现已经不是了。
