需要指出的是，如果要分别计算两边的积分，这就是标准的通量积分。

But, what I want to point out is if you have to compute the two sides separately, well, this is just, you know, your standard flux integral.

如果想用单位法向量来计算通量，还得先把它标准化到单位长度？

Now, if you wanted the unit normal vector to compute flux, then you would just scale this guy down to unit length, OK?

光通量是否合格将直接关系到节能灯的能效等级能否达到标准的要求。

Luminous flux eligibility will be directly related to energy-saving lamps energy efficiency grade can meet the requirements of standard.
