member initial curvature 杆件初始弯曲
Plate with initial curvature 初曲率板
The maximal initial curvature and its relevant location and maximal distortion can be gotten by numerical curve fitting after on-line measurement.
对在线测量的数据进行曲线拟合，求解出最大初始曲率、最大初始曲率对应的位置及最大变形量。
When a curved beam is bending in the plane of the curvature, the neutral axis of cross section is not identical with the axis of gravity due to the influence of the initial curvature.
由于曲率的影响，曲线梁在其曲率平面内弯曲时的中性轴不通过横截面的形心。因此弯矩在形心处要引起正应力，从而引出所谓“等效轴力”的概念。
In type a, rotary subluxation occurs during progression of the curvature. In type b, it seems to be the initial event.
型患者旋转性半脱位出现在曲率增加过程中，而B型似乎初期即发生旋转性半脱位。
