In reverse engineering, problems of how to reconstruct a fairing contour curveare often met.

其次，本文对现有的角点检测方法进行了改进，提高了检测的准确性。

is applied to construct the three-dimension model for finite element analysis. Short circuit and open circuit of the field winding and the teeth and slots structure of the rotor are discussed. An appropriate three-dimensional mesh is made. The corner point problem of conductor is eliminated. Furthermore, a new memory structure for sparse complex matrix and a PCCG method based on it are introduced to save memory and computation time.

在汽轮发电机失磁异步运行转子三维涡流场数值计算模型中，应用了〓法建立了三维有限元计算模型，考虑了转子绕组的开、短路状态及转子齿槽结构，形成了合适的三维剖分网格，解决了三维电磁场有限元计算中角点奇异的问题，创立了一种新的稀疏矩阵的存储格式以及基于该格式的预处理复数共轭梯度法从而减少内存开销和加快了求解速度。

Benefit of this modified shape is that the expansion around the first corner reduces the initial pressure coefficient on the frustum to low values.

这个改进的外型的优点是绕第一角点的膨胀会把截锥上的初始压力系数减少到很低的值。

On 6 October 1941, under the command of Lieutenant Commander Florian Popescu, Carol laid anti-submarine mines in the southern part of Midia-Tuzla barrage, together with the NMS Amiral Murgescu and NMS Dacia mine laying ships, during Operation Varna. On 9 October 1941, Carol laid anti-submarine mines south-west of Cape Kaliakra. On 10 October 1941, at 11:50 hours, after having left Varna harbor with a new load of mines, Carol hit a mine and sunk in 13 minutes, 2 miles away of Galata Burnu lighthouse.
