[英]['kɜ:və,tʃʊə, -tʃə] [美]['kəvə,tʃʊr, -tʃɚ]
弓形布面
5) arch field area
弓形面积
1.
In order to solve the precision problem of approximate calculation of arch field area that we often meet with in the projects of construction and decoration,we obtain the approximate calculation formula of arch field area by using Taylor series of function.
为了解决建筑工程和装饰工程中弓形面积近似计算的精度问题,利用函数的Taylor级数导出了弓形面积的近似计算公式,当圆心角在0°~150°时,使用导出的公式计算弓形面积其精度都能控制在2‰以内,并由此进一步得出了不同圆心角时对应的4个近似计算公式。
6) convex-concave profile
