前凹的

Three cross-sections were made through crown and gingiva of the model tooth. Curve functions of axial buccal crown and gingiva contour of each section were acquired by means of curve fitting, and the angle of emergence pofile was calculated, which represents the degree of undercut.

以下颌第二前磨牙为研究对象，在牙列模型上通过牙冠部、牙龈作3个纵断面，用曲线拟和的方法得到每个断面的牙齿轴面外形及相应牙龈外形的曲线方程，以此分析两者之间的关系并计算牙冠起始外形角度，即倒凹程度的大小。

He works moving about in front of a concave Velleda screen, a secret alcove that is also a surface where this space age cave-man scrawls ideas and drawings, a sounding board for the creative intellectual.

他的作品走动前面的凹Velleda屏幕上，一个秘密壁龛，这也是一个表面的情况下太空时代洞穴人scrawls的想法和图纸，探测板的创造性知识。

It not only can relieve the traction of retinal inner limiting membrane to retina and clivus of fovea but also can get rid of the virose substance adhered firmly to the surface of macular, improve the macular's metabolize, accelerate the furbish of the function of macular.

视网膜内界膜剥离在玻璃体视网膜手术中的应用越来越广泛，其不但可以解除内界膜对黄斑中心凹处视网膜的牵引，还可以清除紧密附着在黄斑前视网膜表面的毒性物质，改善黄斑区局部的代谢，有利于黄斑功能的恢复。

The presence of hyperpneumatization of the frontal sinus concerns with the angle from the line between the junctional point and attachment point of cribriform plate to horizontal line, with the more large angle, the more high rate of frontal gasification, and the more deep olfactory fossa.

额窦高度气化与眶板垂直切线与前颅底交点，这点与中鼻甲骨质筛板附着点的连线与水平线夹角的大小有关，这个夹角越大额窦高度气化发生的几率越大、同时嗅凹也较深。

A larger initial Cobb angle (odds ratio = 4.6), a lower Risser grade (odds ratio = 4.7), premenarchal status (odds ratio = 2.5), osteopenia in the femoral neck of the hip on the side of the concavity (odds ratio = 2.3), and a younger age at the time of diagnosis (odds ratio = 2.1) were identified as risk factors in predicting curve progression.

初次大的Cobb角（优势比＝4.6）、低的Risser级（优势比＝4.7）、月经初潮前（优势比＝2.5）、凹侧髋的股骨颈骨质减少（优势比＝2.3）和诊断时年龄小（优势比＝2.1）是预测侧凸进展的危险因子。

A maths model according to anatomic measure in Transorbital Roof Craniotomy were established to compare with transorbital keyhole approach to frontal base meningioma and pituitary adenoma. We discovered that removing 1cm orbital roof bone will increase the instrument handle angle from 360 to 450(25%).

本文通过经眉弓锁孔去眶顶入路对前颅凹底脑膜瘤垂体瘤的手术治疗，从解剖测量数据建立几何数学模型，与传统眉弓入路进行比较发现去除1cm的眶顶骨质，在理论上手术器械的操作角度从360增加到450即增加25％。

Ennis, high-arched nose and narrow face, was scruffy and a little cavechested, balanced a small torso on long, caliper legs, possessed a muscular and supple body made for the horse and for ghting.

具备鹰钩鼻与窄脸的恩尼司，仪容不甚整洁，肩膀前凸导致胸部稍微内凹如穴，瘦小的上身搭建在卡尺形的长腿上，身体肌肉发达，行动敏捷，天生适合骑马与打斗。

Though designed in Russelsheim, Germany, under the direction of Brit Mark Adams as an Opel, it works beautifully as a Buick - if anything, the toothy Buick waterfall grille, mounted in a new front fascia that includes reshaped lower intakes, gives it a stronger, more upscale presence than the Opel and Vauxhall warpaint it wears in Europe.

巴注：在本巴的努力下，不少英语为母语的国际友人，在今后开始用北京官话发音的&牛X&来代替primal、terrific、brilliant、凹丧母等不文明的单词）。虽然在德国拉素酵母设计，仍然带有别克特征：瀑布前脸，修改过的低进气，看起来比欧宝和卧克操更好看。

The trailing edge of the fourth notch, which causes the pulse, is four degrees before top dead

产生的脉冲的第四凹槽的后缘，位于相应的活塞在前上死点4度的位置的位置上。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
