标准摘要
[中文适用范围]： 本技术报告旨在展示用于表征多模发射条件的环绕通量（encircled flux）的背景。这包括选择环绕通量，以及与衰减测量隐含变化相结合的环绕通量要求的定义。 [外文原描述]： IEC/TR 61282-11:2012(E) is intended to show the background of encircled flux for the characterisation of multimode launch conditions. This includes the selection of the encircled flux and the definition of the encircled flux requirements in conjunction with the implied variation in attenuation measurements.
