The angular extent in a specified plane which contains all the radius vectors of the polar curve of luminous intensity having lengths greater than a specified fraction of the maximum 在某一平面上,一定角寬范圍內所包含的光強極軸曲線上的矢徑長度均大于其最大值的某一特定比例,這種情況定義為光束的發散。

The curve plotted in this way would meet the boundary conditions given and all the polar curves embodied the same wrapping angle 這一方法不僅保證了繪制的型線有給定的邊界條件,同時保證了各型線有相等的包角。
