送横───Send horizontal

acoustic wave field excited by a pulsed point source in a fluid-felled borehole surrounded by horizontal multiple-layered media is solved by the send-analytical method.───声波测井薄层探测的需要，用半解析方法求解了地层为水平多层介质时柱状井孔内脉冲点源激发的声场。

If you can keep your body horizontal when you swim, you create a lot less drag, and all your energy can be used to send you forward.───如果你在游泳的时候能够保持身体的水平，那么你划臂就会省力的多，而且全部的力量都可以用来推动你向前。
