咬合

To simulate the movement of mandibular the articulator has very good effect, and articulator can be widely used in occlusion adjusting, making artificial teeth, and other fields as a guidance in diagnosis and treatment.

用架来模拟人体下颌运动，或用架制作修复体，检验义齿在各方向上有无咬合干扰，及作咬合分析来指导调等方面都具有很高的真实性。

It also carries on four levels of single-factor laboratory experiments with three sample soils: clay, cohesionless soil and sandy soil, concerning three elements: cement mixture ratio, age, water content in order to find out the contractibility under different test conditions, and also the permeability of locking surface between cement soil and concrete.

试验选择粘土，粉砂土和粗砂土三种土质，采用室内试块试验的研究方法，选择水泥掺入比、龄期、含水量三种因素，分别进行了四种不同水平的单因素试验，研究水泥土在不同养护条件下的收缩性，通过水泥土和混凝土咬合面渗透试验来检验两者咬合面的抗渗性。

AIM:To establish an animal model of infraocclusion,probe deeply into the neurobiologic mechanism of infraocclusion of masseter muscle and provide a new method for prevention and treatment of TMD.

目的：建立低位咬合动物模型，揭示在低位咬合下咬肌疼痛的神经生物学机制，为临床颞下颌关节紊乱病的预防和诊治提供依据。

The purpose of this study was to evaluate whether the morphology of the midfacial complex and mandible differed in normal occlusion and Angle Class II, division 1 malocclusion children, and to localize differences with finite-element method and thin-plate spline analysis.

本研究的目的，在评估混合齿列时期，二级异常咬合儿童与正常咬合儿童间，中脸部复合体和下颚骨的形态是否有所差异。使用传统测颅分析法合并几何形态学分析（有限元素分析法、薄板仿样分析法），对其中形态间的变化及其发生机制将有更深入的认识，并能提供临床医师作为早期诊断和治疗的参考。

METHODS: A 3D finite element model of mandibular complete dentures supported by implants was established to analyze the stress status with protrusive or lateral occlusions.

建立种植全口固定义齿和种植全口覆盖义齿的三维有限元模型，然后进行侧方咬合平衡与不平衡、前伸咬合平衡与不平衡模拟加载分析。

Methods:The occlual contact characters of 32 cases with TMD and 30 controls were measured with T-Scanll system in the intercuspal occlusion position, the protrusive movment as well as lateral movement.

材料和方法：应用T—ScanⅡ咬合分析仪对32例TMD患者进行牙尖交错位、前伸及侧方运动的咬合检查并与正常组对照。

Muzzle - Medium length, rounded on upper side to fall away abruptly below eyes. Jaws well defined. Underjaw to be strong and have biting power. Lips close and even, no looseness. Upper teeth to meet tightly outside lower teeth in front.

吻中长，圆形，离眼睛的距离要远，下颌要有力，咬合力巨大，剪式咬合，不允许下牙反咬合。

PURPOSE: To study the stresses and movement of central incisor with three-dimensional dynamic finite element method, in order to understand and describe the process of occluding.

目的：采用动态有限元方法模拟前牙咬合过程，分析上、下前牙在功能咬合过程中的运动和受力变化规律，为全程描述前牙生理咬合过程提供理论依据。

The feet are compact, close-knit and round to spoon-shaped.

咬合是真正的剪状咬合，钳状咬合属于缺陷。

The contorversy on the relationship between occlusion and TMD has not yet been resolved.Most so-called TMD experts de-emphasize the importance of occlusion in the aetiology of TMD, whereas a majority of practitioners still adhere to a concept focusing on occlusal factors in diagnosis and treatment of TMD.

合因素与TMD的关系的争论仍没有得到解决，大多数所谓的TMD专家不再强调咬合在TMD病因学中的作用，然而大部分的开业医生仍然坚信着咬合因素是治疗和诊断TMD的要点的基本概念。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
