Under the mid-latitude mid-range communication,the calculations of channel parameters are taken for different number of transmit antennas at different time and the serving region size is calculated for certain narrow beam.
以中纬度地区的中距离通信为例,计算了不同时刻使用不同发射天线数时的信道参数,并计算了特定窄波束的服务区间范围。

The technology works by focusing sound into a narrow beam, just like light.
这项技术的原理是将声音压缩成类似于光的窄束。
For this effect, we're going to use a very soft, narrow beam, so go under the Style pop-up menu at the top of the dialog (this is where the presets are) and choose Flashlight.
为了这个效果我们需要用到一个很窄的柔化光束。所以在对话框顶部的样式选择菜单中点选手电筒效果。
In other words, ultrasound essentially travels in a very narrow beam — this makes it great for focusing the waves toward a desired area, but not for actual aural comprehension.
换言之,基本上超声波的传播声束极窄,这非常有利于将声波集中至指定地点,但对实际听力则无所助益。
