介绍了Quais 3D-2D法的基本原理,采用有限元仿真分析了不同截面个数对AFPMM电磁性能计算精度的影响.制作了一台样机,实测空载反电势及负载转矩等电磁性能,结果与采用Quais 3D-2D法和相应截面数的计算结果能够较好吻合,为AFPMM的快速精确计算和优化提供了参考.

立体几何翻折问题是立体几何考查时加大难度的一种方式,对多数学生来说具有一定的挑战性,对空间想象能力有较高的要求,因此掌握一定的解题技巧尤为重要.笔者通过对这类题型的归纳整理,发现一个比较实用的切入点,能有效促进问题的解决.
Objective The Mesozoic strata in eastern Liaoning and southern Jilin are relatively well developed.Liu et al.(1963)studied Lycoptera in North China,and they mentioned the fossils of south Jilin,but they were not included in the study due to the lack of sp

The genus Assilina is a taxon within the Nummulitacea that appeared early in the Ypresian(Early Eocene)and continued until the end of the Lutetian(Middle Eocene).Thus,this taxon could be useful for the chronostratigraphy of this time interval.Lower Eocene
在大多数人的印象中,数学就是“做题”,数学就是“脑筋急转弯”.然而数学是每一个孩子从求学开始都必须要学习的一门主要课程,它教给孩子们的不应只是冰冷的数学知识,更重要是要教给学生用数学的眼光看待问题、用数学的思想去思考问题,用数学的方法去解决问题.课程改革明确指出教师应引导学生主动地经历观察、实验、猜想、证明等数学活动过程,发展合情推理能力和初步的演绎推理能力,能有条理地、清晰地阐述自己的观点.
