百度试题 结果1 题目Geological oceanographers use echo sounder to the depth of the water. A. figure up B. figure in C. figure on D. figure out 相关知识点: 试题来源: 解析 D 反馈 收藏
From this time interval (间隔), the depth of the water can be calculated.(脉冲到达水底和反射回水面的时间会被记录下来,从这一时间间隔中就可以计算出水的深度)”可知,回声测深仪(echo sounder)的工作原理就是通过发射声波脉冲并记录其往返的间隔加以计算,与D选项描述相符。故选D项。【小题3】推理判断题...

Ping Sonar Altimeter and Echosounder 100 m range, 25 degree beamwidth, serial communication $460.00 Add to Cart Operating Principle The Ping device emits a brief 115 kHz acoustic pulse from the transducer at the face of the device. The device then listens back and measures the strength of retu...
Simrad echo sounders were later added to the saildrone sensor suite to measure the abundance of pollock, which is also a primary food source fornorthern fur seals,in an area of the Bering Sea where fur seals are known to forage. An echo sounder, known colloquially as a fish finder, sends...
