1) diving descent
潜水下潜
2) dive
[英][daɪv] [美][daɪv]
下潜，潜水
3) under ground water
地下潜水
1.
It is found that pollution factor in under ground water around pollutant-holding water body is consistent with high content pollutant in surface pollutant-holding water body,that is to say,mainly because of organic pollution,the higher the concentration of pollutant in pollutant-holding water body,the higher the concentration of the same pollutant in underground water.
通过对接纳石油化工废水的水体周围地下潜水的监测,发现纳污水体周围地下水污染因素与地表纳污水体中较高含量污染物一致,即都主要为有机污染,纳污水体中污染物浓度高,则潜水中该污染物浓度相应较高。
4) underwater vehicle
水下潜器
1.
A Study on Terrain Matching Assistant Positioning Technology for Underwater Vehicle;
水下潜器的地形匹配辅助定位技术研究
2.
Global path planning is one of the key techniques of underwater vehicle’s intelligent control system,whose purpose is to find a collision-free path from the source position to the destination position according to some optimization criteria.
全局路径规划是水下潜器智能控制的关键技术之一,其任务是在已知障碍物的环境中按照某一最优指标寻找一条从起始点到目标点的无碰路径。
3.
The control system of underwater vehicle was designed by using the advantages of the two methods.
讨论了单变量系统的定量反馈理论（ＱＦＴ）与Ｈ∞两种鲁棒控制设计方法之间的关系，并结合两种方法的优点对水下潜器的控制系统进行了设计研究。
5) submersible depth
下潜水深
1.
The submersible depth of the cage varied with the variation of wave-length,wave-height and wave-period regularly.
应用一系列力学关系,给出了深海沉浮式养殖网箱的运动方程组,在网箱下潜深度的研究中采用绕射理论和Morison方程进行了波浪力分析,讨论了网箱的下潜深度随波浪的波高、波长及周期的变化情况,得出下潜水深比较小时深海网箱的波力变化快,当达到某一个下潜深度以后,波力的变化趋于平缓,从而为深海网箱选用最佳工况提供了一种参考方法。
6) desert phreatic water
沙下潜水
1.
The former widely spreads, a desert phreatic water that is fed by from high to low, slowly flowing, nearby mountain water, having a lower mineralizing degree (0.
一种是沙下潜水 ,主要是周边山区由高向低缓慢地向沙漠区运移所致 ,分布较为普遍 ;另一种是沙漠湖水 ,它是在沙漠区内之低洼地段 ,由于沙下潜水的长期溢出汇集于大小不等的长条状湖泊之中 ,以湖表水 (咸水和卤水 )的形式存在。
