7月11日消息，最近，高铁没有"E座"引起大家热议，有网友开玩笑称，"E给大家测视力去了"。 还有网友表示"E不发音"，所以没有"E座"。 高铁座位是如何分布的？ 二等座：二等座通常采用"3+2"式排列 从左到右依次是A、B、C、D、F A座和F座靠窗 C座和D座靠过道 一等座：一等座通常采用"2+2"式排列 从左到右依次是A、C、D、F A和F靠窗 C和D靠过道 没有中间座位 A和F靠窗 C靠过道 空间更宽敞一些 高铁F座为什么最受欢迎？ 大家也许已经发现，在高铁座位的设计中A座和F座始终靠窗。 商务座 商务座通常采用"2+1"式排列 或"1+1"式排列 从左到右依次是A、C、F或A、F 相比之下，F座不仅能享受窗外的风景，出入也更加便利，也因此F座一度被网友称为"最受欢迎的座位"。 早在今年4月，国家铁路部门就高铁为什么没有E座发布过科普文章。 文中称，早期飞机多是单通道，每排6个座椅分别是A、B、C、D、E、F，其中，A、F座位靠窗，C、D座位靠过道，B、E是中间位置。 时间一长，A-F这六个字母就形成了特定的国际惯例，即A/F即为靠窗，C/D即为靠过道。 中国高铁为了和国际接轨，就延续了这种国际惯例， ...
