1·Perhaps in 2022, when we all attend holographic games at our home stadia, EQ filters will be built in.
也许等到了2022年世界杯，当我们所有人都能够在自己家的视距仪上观看全息的世界杯比赛时，EQ滤波器将被安装在设备里面。
2·In this paper, the transmission performance and transmission manner of superfrequency electric wave and the calculations of stadia and communication distance are discussed.
本文概述了超高频电波在陆地上的传播特性和传播方式及视距和通信距离的计算；
3·This method apply the length of the stadia as base line, survey the vertical angular of the two ends of the base ling by theodolite and get the distance between the station and stadia.
该方法是以视距尺的定长作基线，利用经纬仪测定基线两端点的竖直角，求出立尺点至测站点间的距离。
