回声仪 meaning in English
acoustic sounder
echometer
sounding device
Examples
- Three additional comments on sonic sounder operation are considered pertinent .
关于回声仪的操作方面还有三点必须提及。 - The usual measuring method , that is , to use the water temperature of 1 meter under water surface to adjust the spinning speed of the sounding device , will result in greater measuring errors . this article put forwards the mathematical model of water temperature with the vertical water temperature that was measured at the deepest site of six sections . after adjusting the sounding device w
本文依据实测的6个断面深泡点处的垂线水温建立了水温辅助测深数学模型，依据该模型即可得到保证回声仪测深精度的水温值，用该水温值校正回声仪后，便可得到断面对应于各起点距处的水深值，从而解决了丹江水库三维模型建立的关键问题。 - The 3d model needs three parameters , among them , the distance from the dam and the distance from the starting point of the section can be measured directly , and the depth of the water corresponding to the distance from the starting point of the section can be measured by the sounding device . however , because the reservoir is very deep , the measuring error of the water depth is greater
而建立其三维模型需要三个参量，其中距坝里程、备断面起点距可直接测得，而对应于各起点距的水深值因丹江口水库较深，按通常的方法使用回声仪测深，即以水下二米处的水温校正回声仪的转速来测深有较大误差。
