photospheric facula

英 美
  • 光斑,光球光斑
    1. So a new method to limit the facula was presented to improve illumination efficiency of light-pipe.
      据此,提出了限制光斑进入方棒以提高整体照明系统效率的方法。
    2. In order to calculate the radius of the facula captured by CCD, several algorithms are discussed.
      对光斑圆半径的提取设计了半径提取算法。
