Objective: To investigate the root canal configuration and the incidence and location of the isthmus in extracted maxillary second premolar with single root.

目的：研究离体单根的上颌第二前磨牙根尖1—6mm处根管形态及根管峡部的发生率和位置的情况。

The results showed that the coefficient of raicel decreased firstly in a short distance, and then kept stable form radicel base to radicel apical.

通过对胚根分支系数研究表明：从根基部到根尖，呈现出先递减，然后保持稳定的趋势，采用经验分布函数表示；同时，用四种分支类型已能描述玉米胚根分支特征，且它们的特征参数在一定范围内随机分布。

Stamens inserted in throat; filaments short, bases broad, connate, upper part narrow, free; anthers adnate to stigma head, apex acuminate, exserted; pollen tetrads in loose masses, 2 in each anther cell and fixed on 1 common retinaculum.

雄蕊着生于喉；花丝短，宽，合生的基部，狭窄的上半部分，离生；花药贴生于柱头头状花序，先端渐尖，外露；在松散的群众，每花药室2里的四合花粉和决定1普通retinaculum。

4 Cm wide , apex acute or obtuse , base nearly rotund or slightly oblique

- 4厘米，顶端急尖或钝，基部近圆形或稍偏斜。

The sample comprised 25 patients with the first premolar removed during orthodontic treatment. Digital models and lateral cephalometric records were taken pre- and post- treatment. We chose two kinds of regional superimposition methods on the digital models (One was the mesial zone of the third primary ruga and regional palatal vault, the other was the palate) and Baumrind's best-fit for cephalometric superimposition. The amounts of incisor and molar movement were measured and a comparative study was performed.

三。选择25例拔除上颌第一双尖牙正畸患者治疗前、后的上颌模型进行三维重建，分别使用第三腭皱近心端局部腭穹隆和腭部对同一患者治疗前、后的数字化模型进行局域重叠，以治疗前后头颅侧位片的 best-fit重叠为评价标准，比较三种方法之间的差异，对应用三维数字化牙颌模型纵向重叠评价正畸治疗前、后的牙齿移动进行探索性研究。

Leaf blade elliptic to ovate, base cuneate or rounded, apex acuminate; abaxial wing of samara oblong

叶片椭圆形到卵形，基部楔形或圆形，先端渐尖；翅果长圆形的背翅 6

Stem leaves larger and more crowded toward apex; leaf blade base connate for 2-3 mm, margin smooth or scabrous, apex acuminate, midvein distinct.

茎生叶更大和更密集的向先端；粗糙的叶片基部合生适合2-3毫米，边缘平滑的或，先端渐尖，中脉明显。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
