Other diagnostic features include the presence of a crest along the anterodorsal midlines of the premaxillae,the edentulous maxilla,the presence of a groove-like trough along with the anterolateral margin of the maxilla on the ventral surface,the presence of six conical premaxillary teeth,and no more than six conical dentary teeth which are restricted to the anterior portion of the dentary.

其他主要特征有：前颌骨沿前背中央有一隆嵴；上颌仅前颌骨有6枚圆锥形齿，无上颌骨齿；上颌骨沿前腹侧缘有一沟槽；下颌齿骨齿都集中在前端且至多不超过6枚。依据上述这些特征很易把短吻贫齿龙与其他已知海龙相区别。短吻贫齿龙头骨顶面松果孔大且很前位，头骨腭面的锄骨和翼骨均无齿，它的颈较长(至少可以辨认出13个颈椎)。

Based on the tooth profile plane model's boundary scope and the geometry dimension of the transmission gear, the paper calculates every point's Cartesian coordinate in all parts of tooth profile, such as addendum arc, involute, dedendum easement curve, axle hole arc and other boundary line section.

最后根据齿廓的几何尺寸和五类齿廓平面模型的边界范围，计算齿廓各部分，即齿顶圆圆弧段、渐开线段、齿根过渡曲线段、轴孔圆圆弧段和齿廓平面模型上其他边界线段上点的坐标，并连接这些点生成各部分线段，从而生成齿廓平面模型。

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，要使新旧零部件间的配合达到最佳状态，仍需大量的修整工作，如镗床的齿轮与齿条，若拆卸后齿轮的各项性能指标经检测尚能使用不需更换，而齿条磨损严重需更换，那么齿条及齿条安装面上的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的啮合间隙需达到技术要求的标准，此项工作需时约一天。

AND it also measures the perforations of your stamp !

它还措施齿孔邮票您！

Grooves extend to the finished edge, but rear perforations are not visible.

凹槽延伸到成品的优势，但后排齿孔中不可见。

A subsequent test of the cement plug indicated the existing perforations had not been effectively isolated.
