作者 马中慧 《中学教学参考》 2015年第23期51-52,共2页
在新课程背景下,每位教师都要树立对教材"二次开发"的意识,用审视和探究的目光对待教材,勤于反思,善于总结,不断积累,扬长避短,让自主课堂充满智慧。笔者将四节关于《功》的"同课异构"的研讨课中一节教学设计呈现出来,与各位同仁共享。

The conception of "advanced radar" is introduced and lint forward, while it is proved that the weakpoints of interference can still be employed. Meanwhile, the paper expounds the principle how Over-The-Horizon Radar(OTHR) works, and derives the OTHR interference equation. By listing the OTHR examples, it analyzes and calculates the equivalent power of the OTHR and the sensitivity of the receiver to build up a block diagram how the interferencer is structured. Hence, the effective area is achieved, and OTHR can be intereferenced effectively with not so high equivalent power. 展开更多
