反射

• Since there are four reflections, the exiting image will be right-handed .
  因为共有四次反射，出射的像将是右手坐标系。
• A detector at b will then record the time of arrival of the reflected wave .
  于是在B点的检波器将记出反射波到达的时刻。
• Seeing is the scintillation of image caused by turbulence in the atmosphere .
  宁静度是由大气湍流所引起的象的闪烁反射。
• The lower half of the pattern will be obtructed by the presence of the mirror itself .
  图样的下半部被反射镜本身挡掉了。
• It is helpful to think of the process of reflection in the following way .
  按如下的方法来想象反射过程对我们是有帮助的。
• It traps many of the heat waves which would otherwise bounce back into space .
  它可吸收大量未反射到太空中去的热辐射波。
• The suspension of the mirrors must be very frictionless, but strongly damped .
  反射镜的悬挂既要无摩擦，但又要有强阻尼。
• The curvature of the film is concentric with the mirror behind the meniscus .
  胶片的曲率是和弯月透镜后面的反射镜同心的。
