基于声衰减原理进行水体含沙量测量的方法,需要测量声压的衰减值。本文针对悬浮液中的声衰减测量问题,作了探讨。提出了单一回波脉冲幅度法、比值法、面积比值法,并就其原理及检测中的技术问题作了论述。
The method of measuring the sediment concentration of a water body based on the principle of sound attenuation needs to measure the attenuation value of the sound pressure. In this paper, the acoustic attenuation measurement in suspension is discussed. A single echo pulse amplitude method, ratio method and area ratio method are presented. The principle and the technical problems in detection are also discussed.

当我们重新思量体育的目的和功能，思量我们的学校体育的目标时，我们已经认识到了体育要“以人为本”，要培养“终身体育意识”，要形成“终身体育习惯”。尤其是在学校体育教学中，终身身体意识的培养以及良好锻炼习惯的养成，更具有迫切的意义。鉴于目前的学校体育现状：重课堂教育，轻课后锻炼；重知识传授，轻观念养成；重技术教学，轻兴趣培养；重测试结果，轻习练过程等现象，我们需要寻找一种合适的活动方式或者教学体系来扭
