第二个问题，关于中国媒体所公布的这个视频，当中有模拟发射干扰弹的画面。
My second question is that, in the video published by the Chinese media, there were images of simulated firing of decoy flares.
从12月的第二周开始，OT IS将进行严格的声学测试，以进一步模拟发射条件。
Beginning the second week of December, OTIS will be subjected to rigorous acoustic testing to further simulate launch conditions.
这是因为在空中传播的高频信号中，两个模拟发射频道的之间要有一个空置的频道这样才不会干扰相邻的频道。
That was because, in over-the-air VHF broadcasting, the channel between two analogue stations had to be left unused so that it would not interfere with adjacent ones.
