Aocording to different given conditions,two drawing methods for front view of two elbow are given in this paper.

根据不同的已知条件 ,给出了两节弯头主视图的两种绘制方法 ;并建立了正圆锥两节渐缩径弯头的数学模型 ,以便更准确地绘制其展开

A two-stage model is established near the optimal solution of sectional optimization of continuous variables,and the quite small element method associated with the dimensionless variable technique is adopted,then the optimized model with constraints of size stress and displacement under multi-loadings is obtained.

通过将截面离散变量映射为连续变量的途径,建立了力学模型,在连续变量截面优化最优解附近构造两节模型,并采用两节无限小单元的无穷组合的方法和变量无量纲化技术对膜结构截面离散变量进行了优化。

The method to solve average body temperature by Professor Gagge s two-node model was analyzed, and then a more simple body temperature regulation model (one-node model )was established according to the thermal balance of human body and the ambient.

分析了利用Gagge教授“两节点模型”求解人体平均温度的方法,然后根据人体与环境间热交换的平衡建立了一个简单的人体温度调节模型——“一节点模型”,避免了求解人体平均温度时所需要的复杂计算,该模型不但减少了计算求解的工作量,而且结果与“两节点模型”间有着很好的一致性;作为实际应用,利用该模型制作了温度突变环境下人体温度求解表格及曲线,总结了在该环境下人体温度变化规律,从而找到了热感觉指标TSENS在温度突变环境下的实用途径。
