查询词典 variational equation

The macroprogram is written by using the elliptical parametric equation, then some actual work problem can be solved with the macroprogram.

在数控编程的实际应用中，常见的是直线插补和圆弧插补，没有椭圆插补，但在实际生产中，往往遇到许多椭圆的零件需要加工，如果手工常规编程就无法编制出椭圆的加工程序，为了解决这个问题，在数控编程中有宏程序可以做到椭圆的加工，本文按HCNC-21T系统（在其他系统只不过是宏程序的格式不同而已）对椭圆做内、外的加工编程举例，还在内椭圆的加工中先加工一个工艺孔，巧妙利用椭圆的参数方程来编写宏程序，用宏程序来解决一些实际的工作问题。

ISO834 and parametric equation approach are lack of pertinence. The results may be too conservative. The temperature obtained by zone model is low, so that it is not suitable for the performance-based fire protection design on this structure. Field model considers the heterogeneity of environmental temperature, and its result is close to the real fire, so that it is commended to the performance-based fire protection design on steel staggered-truss structure.

国际标准升温曲线和参数化室内升温曲线不考虑火源功率、建筑通风口等因素，缺乏针对性，分析结果偏于保守；区域模型所得温度偏低，不宜用于交错桁架结构的性能化抗火设计；场模型考虑了火源功率及环境温度分布的不均匀性，和实际火灾较接近，计算结果相对较为准确，可用于结构的性能化防火设计。
