| 1. | Pairs of such reflecting surfaces are known as etalons . 这样一对反射面通常称为标准具。 |
| 2. | The planes of the wave front and the reflecting surface are also normal to the plane of the figure . 波阵面的诸平面与反射面都与图面垂直。 |
| 3. | The light wave that has bounced off the reflecting surface is called thereflected ray 从反射表面跳回的光波称为反射线。 |
| 4. | To us , it ' s just a shining , reflecting surface where the air ends and the water begins 对于人类而言,这里只是能反光的界面,它是空气与水的分界线。 |
| 5. | Beware of cloudy days and reflecting surfaces : snow , , water , sand and concrete . you can still burn 小心多云天气和反射光线平面:雪、水、沙子和混凝土。你仍然可能因此而晒伤。 |
| 6. | The angle drawn at the point of incidence ( intersection of ) a reflected ray and the normal line perpendicular to the reflecting surface 中义光线在物体表面的投射点上反射出来的光线与物体表面垂直法线所夹的角度。 |
| 7. | Made of durable acrylic plastic frame and high quality mirror , high reflecting surface & long - lasting coating . light weight and small size easily for carrying and demonstrating anywhere 遗忘已久的哈哈镜有再面世,给大人小朋友无比欢欣!此哈哈镜是轻巧设计,只有2尺高,尺半阔,让学生了解到光的反射定律 |
| 8. | Concave reflecting surfaces of spherical cap , paraboloid and hyperboloid of revolution are investigated with regard to the dependence of the levitation force on the section radius rb and curvature radius r ( or depth d ) of the reflector 针对球面、旋转抛物面和旋转双曲面三种形状的凹面反射端,系统研究了悬浮力与反射端截面半径r _ b和曲率半径r (或深度d )之间的本征关系。 |
| 9. | Even if he doesn ' t recognize himself yet in a reflected image in a portion of a mirror , he will still have fun misting up the glass , making faces , disappearing and then reappearing in the reflecting surface , looking inside to see if there is someone there 即使他不认为自己在一个被反射的镜子里,他仍然会很有趣地玩耍玻璃,扮鬼脸,消失然后在出现在镜子反射的表面,并看看里面是否有人。 |
| 10. | Light gas gun was used to create shock pressure . staged samples , cuneiform window with aluminium coat on the reflecting surface and visar ( velocity interferometer system for any reflector ) were employed in the experiments . polymethyl methacrylate and ofhc copper were assembled as the impactor to impact staged samples 采用气炮加载,利用台阶样品、双点式visar ( velocityinterferometersystemforanyreflector )和镀膜楔形窗口技术,以有机玻璃和无氧铜组合为飞片,碰撞无氧铜台阶样品。 |
