尖齿的

The height of a whole tooth is the distance from the tip of the tooth to the bottom of the gullet in front of it.

全齿的高度是指锯齿尖到两个齿尖间隙凹槽底部的距离。

Petiole 3-5 mm; leaf blade papery, ovate-lanceolate, 3.5-5 × 1-1.5 (-2.5) cm, base subrounded or attenuate, margin crenulate, apex acuminate or acute; lateral veins 4-6 pairs, slightly curving forward and disappearing before reaching margin.

叶柄3-5毫米；叶片纸质，卵状披针形， 3.5-5 * 1-1.5 (-2.5)厘米，基部近圆形或渐狭，具细圆齿的边缘，先端渐尖或锐尖的；侧脉4-6 对，稍弯曲前锋和在到达边缘前消失。

Petioles acute-triangular in cross section, 5–20 cm, sheaths triangular-ovate; leaf blade triangular-ovate, 20–45 × 17–40 cm, 2–3-ternate-pinnate; leaflets subsessile or short-petiolulate, long-ovate to elliptic, 2.5–12 × 1–6 cm, base obliquely cordate to cuneate, margin coarse-toothed or serrate, apex acuminate, glabrous or hispidulous along nerves.

叶柄锐尖三角形的在横断面上，5-20厘米，鞘三角状卵形；叶片三角状卵形， 20-45 * 17-40 厘米，羽状2-3回三出；小叶近无柄或短的小叶柄，长卵形到椭圆形， 2.5-12 * 1-6 厘米，基部斜心形对楔形，边缘粗糙的齿或有锯齿，先端渐尖，无毛的或沿着叶脉具短硬毛。

The family is characterized by a primitive protrogomorphous-sciurognathous zygomasseteric structure and pauciserial incisor enamel, but the cheek teeth are precocious in development of hypocone and hypolophid.

共 4属 6种。新科的特征是：始啮型头骨-松鼠型下颌；门齿釉质层散系；颊齿具有发育的次尖和下次脊，后期种类上颊齿的外侧齿尖的唇侧发展成平凹到新月形。

Leaves deciduous; petiole 3-4 cm, nearly glabrous; leaf blade ovate or ovate-oblong, 9-13 × ca. 8 cm, papery, abaxially densely rufous pubescent on veins, adaxially glabrous, base subcordate, margin doubly serrulate with adpressed acute teeth, 3-lobed; middle lobes triangular-ovate, apex acuminate; lateral lobes in upper part of blade, much shorter and apex acute.

叶脱落 叶柄3-4厘米，近无毛；叶片卵形的或卵状长圆形， 9-13 *长约8厘米，纸质，密被红棕色短柔毛在脉上，正面无毛，基部近心形，边缘重细锯齿具紧贴锐尖齿，3裂；三角状心形的中间裂片，先端渐尖；叶片的侧的裂片在上半部分，很多短和先端锐尖。

The Optimized Design and Reshaping of Profile of Skiving Cutter with Plane Flank for Gleason Gear

由于弧齿锥齿轮尖齿刮削刀盘的切削刃采用斜角直线造形法，其造形误差和重磨误差大，本文提出了优化造形的方法。

三尖一种有三尖的器官或部分，尤指三尖齿

The simulation results show that the asymmetry structure of the ratchet die cavity influences the BMG's flowing behavior greatly. During the material filling tooth cavity, dead zone volumes exist and situate on the areas with sparse teeth distribution. The full filling or not of the ratchet tooth tips, as the final filling region of the forming process, determines the super-plastic forming quality. Adopting smaller punch speed or longer load holding time is necessary for full filling of the tooth tips.

研究结果表明，棘轮模腔结构的不对称性对材料的流动行为影响显著；在材料向齿形的充填过程中存在流动死区，死区的位置处于齿形分布较稀疏的部位；齿形尖角是成形的最后充填部位，在终成形阶段采用较小的压下速度或较长的保压时间，有利于齿形尖角的完全充满。
