It's going to be a good crop this year.

The flood bad crop.

水灾导致歉收.

By setting two perspective cameras at the first molars of the upper jaw and using the OpenGL selection mode, the real-time collision detection with high efficiency between lower and upper jaws can be realized as the lower jaw rotates around the axis of the articulator.

该方法通过在上颌左右第一磨牙近中舌尖处建立透视视景体，利用OpenGL的选择模式，可以实时地检测下颌模型绕牙合架转动轴线旋转过程中与上颌模型碰撞对位情况，效率很高。

'We should not assume that the state is the articulator of those purposes and will,' he says. 'And, indeed, 25 years ago there was a rather massive divergence in the expression of popular purposes and state power.'

他说，大家不应该假定国家就是这些目标和志向的标准落脚点，实际上，25年前的普遍目标和国家权力就有着各种各样不同的说法。

"The incisors, in front, are shaped mostly for Biting, the pointed canines for tearing, and the premolars and molars for grinding food." articulator registration The condition of being worm-eaten.

前方的切齿主要用来咬住食物，尖的犬齿则撕裂食物，而前磨牙和磨牙则用来磨碎食物。

However, former methods used in confirming articulator parameters and jaws relationship transferring have different problems because of low precision or inconvenient manipulation, moreover, the function of mandible movement simulating by mechanical articulator is limited.

但是以往确定牙合架参数及转移颌位关系的方法存在不同程度的精确度低、操作繁琐的问题，而且用机械牙合架模拟下颌运动的功能也有限。

Methods: To make simple mandibular collision models with 3 cases of fresh and intact human mandibular specimens with artificial tooth material according to the principle of Hanau articulator with MTS biological material testing machine.

方法：3具新鲜离体下颌骨标本，利用牙托粉和下颌骨，根据Hanau牙合架原理制备对牙合模型，在生物材料试验机上进行验证。

RESULTS: The algorithm model to simulate the protrusive movement of complete denture on articulator was established and was testified by the true case in this study.

结果：建立了用于模拟全口义齿在牙合架上三维前伸运动的算法模块，并在实际病例进行验证。

Firstly, the Gauss map of points on the cylinder and a random sampling method are used to compute the rotation axis equation of the simple articulator.

首先通过构造圆柱面上点的高斯图和任意采样的方法，计算出简单牙合架转动轴线方程。

It covers his introduction to dentistry and explores his prolific articulator designs and contributions to the prosthodontic literature.

它涵盖了介绍，并探讨他的牙科架的设计和丰富的贡献，补缀文献。

Moreover, articulator is also used as an assistant tool of different occluding analyzes, abnormal amending, and jaw repair surgical therapy.

此外，牙合架也是作各种咬合分析、正畸、正颌外科治疗的重要辅助工具。

This paper describes the realization of the simulation of mandibular movements and occlusal contacts detecting when building virtual articulator system.

文章论述了在建立虚拟牙合架系统的过程中，下颌运动模拟和上下牙咬合接触点显示两大功能的实现方法。
