石膏模型

The technique of direct carving was a break with the nineteenth-century tradition in which the making of a clay model was considered the creative act and the work was then turned over to studio assistants to be cast in plaster or bronze or carved in marble.

6，第二个层次：在传统的做法中，有这样两件事情：1 制作粘土模型被认为是一种创造性的艺术，2 这些作品被交到了助手那里，(这里有两个 or，分别连接谁和谁，谁和谁并列)要么被铸造成石膏或青铜。

Methods A life-size plaster cast of human head was used as the anthropomorphic model. Fifteen experimental conditions were studied. Nine linear distances between landmarks and Nasion were measured each time. These were compared to the standard anthropometric measurements using the same landmarks.

以石膏头像为研究对象，用系统在15种不同条件下测量模型面部9个点至鼻根点的距离，以用游标卡尺得到的测量结果为评判标准与前者比较。

METHODS: 311 working cast models were selected to perfuse with three kinds of tray including small size, middle size and large size randomly in clinic.

以期依据分类指导临床灌注模型，控制超硬石膏粉的用量和标准水粉比例，达到提高模型质量、节约材料的目的。

PURPOSE: The objective of this study was to survey the amount of working cast model of denture restoration, and to calculate the amount of die stone powder of each working cast model, then to classify the working cast model, with the expectation to perfuse the working cast model in clinic according to this classification, and to achieve the goal of increasing quality of working cast model and saving materials.

目的：通过测量义齿修复工作模型重量，计算各模型所含超硬石膏粉的用量，再按其粉用量，对义齿修复工作模型进行统计学分类。

Low Dilatabilit y and great waxiness,its tenacity is twice more than common gypsum,its the ideal material forodontology model

可塑性的石膏，韧性比一般超硬石膏大二倍，是医学齿科模型的理想材料。

Refer to the domestic and foreign literature material, to establish traumatic joint stiffness model with New Zealand big white rabbit;caused the right knee joints of the big white rabbits closed trauma with the appropriate mothod,then fixed the behind-right knee joints 4 weeks with the gypsum and the bandage;after 4 weeks, removed fixture,examined the animal blood rheology,the joint range,the skin temperature, the arthrocele extent and so on ,to authenticate whether modeling succeeded or not.

参考国内外文献资料，用新西兰大白兔建立创伤性关节僵直模型；用适当的方法造成大白兔右后膝关节闭合性损伤，用石膏绷带、绷带固定4周，4周后拆除固定。期间观察皮肤温度、关节肿胀度、关节活动度，检测动物血液流变学等指标，以验证模型建立是否成功。

Based on the statistical damage evolution equation considering stress damage threshold and the multiple rheological model of gypsum breccias, the damage rheological constitutional model is established from hypothesis of strain equivalence. The calculated results of the model agree well with creep test results.

在Kachanov提出的一维蠕变损伤演化方程的基础上，建立了同时考虑瞬时损伤和蠕变损伤的流变本构模型，理论值与试验值基本一致，验证了提出的蠕变损伤演化方程是正确的，所建的损伤流变模型能够较好地描述石膏角砾岩的加速蠕变阶段。
