应用确定性力学方法，对齿板应力和应变进行了有限元仿真研究，通过对仿真结果的分析，认为基于确定性力学的齿板应力和应变仿真只能部分反映其真实受力状态，齿板类零件在有限元仿真中的载荷施加方法应进一步研究，以真实地反映齿板在实际工况下的受力情况。

This means that the alveolar bone at lingual side contributed similar effects on the mobility of incisor to that at facial side, and the effect of alveolar bone of mesial side was also similar to that at distal side.

即上颚犬齿在近心侧齿槽骨缺损与远心侧齿槽骨缺损时对牙齿动摇度的影响相当，且舌侧齿槽骨缺损对牙齿动摇度的影响和唇侧齿槽骨缺损时相同。

This means that the alveolar bone at the lingual side contributed more effect on the mobility of incisor than that of the facial side. However, the effect of alveolar bone of the mesial side was closely to the distal side.

即上颚正中门齿在近心侧齿槽骨缺损与远心侧齿槽骨缺损时对牙齿动摇度的影响相当，但舌侧齿槽骨缺损对牙齿动摇度的影响却大於唇侧齿槽骨缺损。

If the bevel gear used in the processing module mid-point of the standard spur gear tooth milling cutter with big-deep into the alveolar knife milling, then the big-toothed on the "fat", little-endian tooth on the "thin."

如果在加工时采用伞齿轮中点模数的标准正齿轮铣刀以大端齿深将齿槽一刀铣成，那么大端齿形就&肥&，小端齿形就&瘦&。

The dimensions of dental arch in Chinese were very similar to Japanese, South and Central American Indians, but wider and shorter than Central and South American Indians.(5) The superimposition of dental arch form showed that the four races of Mongoloids had similar ovoid dental arch forms.

但中美印第安人之齿列弓长径比国人者长，南美印第安人之齿列弓宽、长径则比国人者更长；(5)检讨四种人种的齿列弓形态的重叠影像，可发现四种蒙古人种的齿列弓形态都极为酷似，呈现弧度较大的椭圆形。

The present invention relates to a reduction box mainly composed of coaxial line input shaft, output shaft, internal ring gear, eccentric toothed plate engaged with the internal ring gear and pin shaft.

To cooperate with new and old parts: although standard zero, components, but in between interchangeable in assembly parts, and to make the optimal coordination between trim, still needs a lot of work, such as the gear and rack, boring if after removal of gear various performance indicators are used by detecting without the need to change, and to replace worn rack, rack and rack positioning pin hole on installation bolt holes and should be first, reoccupy hand crossed positioning drills and tapered reamer to match the drill and match hinge, and after the installation of new and old super-modulus gear mesh clearance to achieve technical standards, this work takes about one day.

。新，旧零部件重新配合过程：尽管标准零，部件间具有互换性，但在装配中，要使新旧零部件间旳配合达到最佳状态，仍需大量旳修整工作，如镗床旳齿轮与齿条，若拆卸后齿轮旳各项性能指标经检测尚能使用不需更换，而齿条磨损厉害需更换，那么齿条嘉逸条安装面上旳定位销孔和定位螺钉孔就需先划线定位，再用手电钻及锥形铰刀重新配钻和配铰，且新齿条安装完毕后与旧齿轮旳啮合间隙需达到技术要求旳标准，此项工作需时约─天。
