摘要
在精确计算法和简易计算法的对比计算和讨论分析的基础上 ,提出了一种异径管展开面积的近似计算公式 ,实例计算表明 。
Based on the compared calculation,discussion and analysis of the accurate calculation method and simple calculation method, an approximate calculation formula for developed area of different diameter pipe was put forward.It is shown through calculation of practical example that the method has much less tolerance than simple calculation method.
