They found Mary, as usual, deep in the study of thorough bass and human nature; and had some new extracts to admire, and some new observations of thread-bare morality to listen to.

她们发觉曼丽还象以往一样，在埋头研究和声学以及人性的问题，她拿出了一些新的札记给

An equation is derived by theoretical analysis, to establish a relationship between suspended sediment concentrations and ADCP echo intensity output. For the survey at the entrance to Jiaozhou Bay, an ADCP is mounted on a moving vessel; the calibration coefficient in the equation is determined by in situ measurement. Then, a semi-empirical formula is obtained and used to calculate suspended sediment concentration profiles along several crosssections.

理论分析获得了海水中悬沙浓度与ADCP输出的回声强度之间的函数关系式；在胶州湾口门进行走航式测量，同步采水样进行现场校正来率定相应的ADCP声学信号，获得了计算悬沙浓度的半经验公式；进而得到走航断面准同步的悬沙浓度剖面。
