When food chip was masticated between dentitions, place food chip in posterior occlusion bilaterally.

在双侧后牙区放置食物片的咬合状态下，负载2kg、4kg、6k、8k咀嚼力时，测量并计算出基牙在近远中向、唇舌向、垂直向的位移、倾斜、扭转量，统计分析不同固位力大小对基牙位移影响的意义。

Methods Three kind of palatal connecter palatal bar, anterior-posterior-lateral palatal bar, palatal plate were used to retain RPDs. Then food chip was masticated between the upper and lower dentitions on left side.

运用上领双侧游离缺失模型，制作三种腭部大连接体，分别为中央开&天窗&的腭板、前后侧腭杆和腭杆的可摘局部义齿。

Unilateral posterior crossbite is one of the most frequently occurring malocclusion in the mixed and early permanent dentitions.

混合牙列和早期恒牙列期单侧后牙反牙合是临床较常见得一类错牙合，绝大多数患者约80％伴有下颌偏斜，上下中线不齐。

The results show that single structure parameters (width and depth of flow path/passage, and height, and angle of dentations) are local and difficult to represent the anti-clogging ability of emitters. Characteristic structure parameters(minimum size of cross section, hydraulic radius and dentitions spacing) can represent the anti-clogging ability of emitters in a sense. There are anti-clogging critical values under the test. Rated flow Qr and the ratio of diameter of labyrinth passage to diameter of particle η are well cor related to the anti-clogging ability and have anti-clogging critical values too.

结果表明：用单一结构参数(流道宽度 W 、流道深度 D 、齿高度 h 和齿角度θ)表征其抗堵塞性能存在局限性；结构特征参数断面最小尺寸 min(D，W、水力半径 R 和齿间距 l 能较好反映滴头流道横、纵断面的结构特征，在不同程度上表征了流道的抗堵塞性能，且在试验条件下各自均存在抗堵塞临界值；滴头额定流量 Qr 和迷宫滴头径粒比η与抗堵塞性能相关性较好，且存在抗堵塞临界值。

Methods: 11 patients with periodontal disease and dentitions defect were treated by SDA.

对象为采用SDA治疗法修复的11例牙周病牙列缺损的患者，戴牙时间为6个月。

The real cause for the second molars malocclusion is the crowding and it happens in the posterior region of dentitions.

从本质上讲，第二磨牙错牙合是拥挤的表现，主要在磨牙区。

Dentitions of these patients were adjusted by orthondontical and restoration methods.

27例前牙缺失伴错牙合患者，用正畸方法对缺失的牙列进行调整，再辅以修复。

The subjects in the first group (n = 30) had complete normal dentitions including third molars; those in the second group (n =30) had impacted right and left third molars.

在曲面断层片上分别测量上颌第一和第二磨牙与腭平面所成的角度。

Methods sample consisted of 2 groups. The subjects in the first group (n = 30) had complete normal dentitions including third molars; those in the second group (n =30) had impacted right and left third molars.

样本分为两组，第一组的研究对象（n=30）具有完整的正常牙列，包括上颌第三磨牙。

A historical region of southwest France between the Pyrenees and the Garonne River. The duchy of Aquitaine was joined with France after the marriage of Eleanor of Aquitaine to King Louis VII in1137, but its possession was disputed after her subsequent marriage to Henry II of England.

阿基坦法国西南部一个历史地区，位于比利牛斯山和加隆河之间，在1137年阿基坦的埃莉诺与国王路易斯七世结婚之后阿基坦公国加入法国，但当她再嫁英国亨利二世后，其归属权便受到争议

There are moments when I look at the smiling , happy faces of my expectant staff and wonder how they will cope when confronted by an outraged housemaster along with an unrepentant and recalcitrant bleached blond teenager in 18 years ' time .

有时候，我看着那些满怀期待的员工微笑，幸福的脸，想着当他们遇到一位愤怒的宿舍管理员和一位不知悔改，叛逆，而且将头发染成白色的18岁少年时，他们会如何处理。
