查询词典 material point

The appropriate assembly temperature is related to mechanics properties of material and operating temperature, so reiterative computations are necessary to find an appropriate assembly temperature by the method that makes the maximal tensile stress smallest under conditions that the maximal compressive stress is less than the compressive yield point of material.

安装温度的选择与材料的力学性能及零件的工作温度紧密相关，因此选择合适的安装温度需要反复计算，其方法是在保证循环中的最大压缩应力小于材料压缩屈服点的条件下，使最大拉应力最小。

The computational formula of dew point temperature was presented according to the physical feature of water vapor such as Michell's saturated water vapour pressure formula. Surface temperature inside wall body was also calculated. Then the comparison between them verified whether wall body has dew. At the same time, the temperatures of every material layer inside wall body were calculated. The partial pressures of saturated water vapour and actual partial pressures of water vapour for every material layer inside wall body were obtained. The two were compared so as to verify whether condensation appears inside wall body.

根据Michell饱和水气压计算公式等水蒸气的物理特性，给出了露点温度计算公式，再计算出墙体内表面温度，将二者进行比较，从而验证墙体是否结露；同时计算出墙体内部各材料层温度，求出墙体内部各材料层的饱和水蒸气分压力及各材料层实际水蒸气分压力，将两者比较，从而验证墙体内部是否出现冷凝。

The title and bill of material in engineering drawings are important data source for product data integrated management. In order to reuse the CAD data, the paper presents an effective method for extracting part information from existing engineering drawings. Through analyzing the format of title and bill of material, several shape-position characteristics of tables are summed up from the view of macro-layout and microstructure. A new method to automatically extracting drawing information based on cell-grid and feature-point is proposed along with its algorithm principle and implementation steps. A software package based on the method mentioned above is developed and used in practice.

1引言工程图是工程设计的主要成果和制造加工的主要依据，CAD软件的广泛应用使得传统上对于纸质图纸的管理模式转变为对大量电子文件的管理模式·由于文件系统在实际应用中不能适应复杂大规模的管理模式，已经出现了各种各样的图档管理系统[1]·工程图中包含的零件信息在表现形式上体现纸格式的标准化为批量提取数据提供了可能性·作为计算机处理的对象，图纸信息自动识别成为数据管理和系统集成的一项关键技术·当前CAD管理系统所处理的数据对象比较复杂，面临由不同企业使用不同的绘图软件生成的图纸，其中的标题栏和明细栏或者由软件自动生

Group of finite element analysis was divided into 2 kinds(compact bone and cancellated bone ), 10, 50, 100, 200, 400 kinds of material attributes groups based on the gray value. All models were assigned with material attributes and tested in ansys for mechanics datas of nodes on surface of femoral neck. In group of biomechanical testing, twelve specimens of femoral superior segment were treated with compressed testing to harvest mechanics datas of measuring point same as that of group of finite element analysis. Results One-Way ANOVA showed as follows.
