首先采用扫描电镜对25颗4的髓腔壁进行系统观测，并分区定点摄影，然后对扫描电镜照片进行形态测量。

Objective The purpose of this study is to reveal the micromorphological featare and law of the pulp cavity walls of human premolars and to provide a micromorphological basis for root canal therapy and dentine sensitivity.

目的：揭示在髓腔壁的微细形态学规律，为根管治疗术以及理解牙本质过敏现象提供应用形态学基础。

Objective The purpose of this study is to reveal the micromorphological featare and law of the pulp cavity walls of human premolars and to provide a micromorphological basis for root canal therapy and dentine sensitivity.

At last, in Ansys 9.0 software, by Boolean operation, different parts of the crown （ enamel, dentin and pulp cavity） were separated, and the 3D meshes were created respectively.

再将模型导入Geomagic7软件中进行精修和细化，形成有限元分析软件可识别的实体三维模型，最后，将牙体组织的三维实体模型在Ansys9.0软件中进行布尔运算，区分出釉质、牙本质及髓腔系统，并分别进行了网格划分。

Results: 1. The three-dimension (3D) model reconstructed by Micro-CT scan data objectively reflected the real contour and the pulp cavity figure of the tooth.

实验结果： 1。本研究采用Micro-CT扫描，准确、安全、无创伤、分辨率高，所得到的断层信息可以较清晰的显示牙体组织及根管系统等结构，又不破坏标本的完整性。

This usually extends quite far, and in males may reach beyond the lip line. The tusk grows from its base as fresh dentine is slowly deposited over the surface of the pulp cavity.

此肉囊的范围较大，雄性可达到唇边，象牙由牙根开始生长的嫩牙首先在牙座部位缓慢形成。

Results A satisfactory three-dimen- sional finite element FE model of the first mandibular premolar with pulp cavity was constructed which including 101564 elements and 144053 nodes.

作为一种理论应力分析方法，有限元分析方法常用于工程力学研究，直到1973年由Farall川等首先应用于牙列修复的优化设计中。

第一前磨牙；髓腔壁；牙本质小管；扫描电镜；微细形态学

In the middle of a blow, then deep, because under the surface pulp cavity, so hypertrophy, fragrant like a circle after circle, but it tastes, flaky, crisp, Soft three mixed feelings.

炸时用的铁勺子，直径约5寸，四周下凹，中央凸起，用另一勺将那种混合浆舀入面窝勺，在中间一刮，然后下锅，下凹处因面浆多，所以肥厚，炸成后像个圆圈圈，吃在嘴里，酥、脆、软三种感觉混合。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.

一方面，有讨论，工程理事会和联盟关于延长工作时间短至9月底。
