共焦椭圆 meaning in Chinese
confocal ellipses
Examples
- The slow - wave characteristics neglecting and taking account of space harmonics ( sh ) for periodically iris - loaded confocal elliptical waveguides are analysed , and the dispersion equation and the mean coupling impedance of this structure are obtained by
分析了周期膜片加载共焦椭圆波导,在考虑空间谐波和不考虑空间谐波两种情况下的慢波特性。应用场匹配方法得到这种结构的色散方程和平均耦合阻抗。 - On the ground of educative theory , this paper exposits connotation and characteristic of project - based learning and why we should also enforce project - based learning in high school . as far as substance of project - based learning and objective circumstance what it should have are concerned , it points out the practical ability . at last , based on that university physics education has relatively longer cycle , it proposes stage pattern for enforce project - based learning and give two concrete cases , which discuss capacitance of confocal oval - shaped stylar capacitor and potential distribution of charged conductor of surface being uniparted hyperboloid
本文在具体的教育理论指导下，阐述了研究性学习的内涵及特点；在大学物理中实施研究性学习的意义；以及就研究性学习的实质和所需具备的客观条件而言，论述了研究性学习在高校中实施的可行性；并根据大学物理教育具有周期性相对较长和专业循序渐进的特点，提出了研究性学习的阶段性模式，并给出了具体的实例，利用保角变换法讨论了共焦椭圆柱形电容器电容及单叶双曲面带电导体的电位分布。
