求翻译：设计内容：对于通道挡烟板参数设计，主要分两点:第一最适合挡烟板的深度,第二最适合的挡烟板间的间距.而fds软件模拟的就是在不同深度和间距下烟气的流通情况和通道各点的温度变化情况,目的是让火灾发生时尽量延缓烟气的在通道内的流通速度从而最大程度上的为人群的疏散争取时间，减少火灾中烟气对人群发的影响。是什么意思？

Design: smoke screen plate parameters of the channel, mainly divided into two points: first, the most suitable depth of the smoke screen plate, the spacing between the plates of the second most suitable for the smoke screen. Of fds software simulation is the depth and spacing flue gas circulation an
