查询词典 sea water

This method is based on the Snell law of acoustic propagation in water. Different velocity gradients among linear layers in water are utilized to draw the sound ray chart, and a mathematical model of the geometric operational range is built. Furthermore, the geometric homing range is predicted with sound ray density, a prediction system of geometric operational range for acoustic homing torpedo is designed and the function of the system is realized through a system software. The sea trial demonstrates the prediction validity of the system.

A world without professors or specialists or house–keepers with the profiles of policemen, a world which one could slice with one's thought as a fish slices the water with his fin, grazing the stems of the water–lilies, hanging suspended over nests of white sea eggs...How peaceful it is drown here, rooted in the centre of the world and gazing up through the grey waters, with their sudden gleams of light, and their reflections—if it were not for Whitaker's Almanack—if it were not for the Table of Precedency!

这个世界里没有教授，没有专家，没有警察面孔的管家，在这里人们可以像鱼儿用鳍翅划开水面一般，用自己的思想划开世界，轻轻地掠过荷花的梗条，在装满白色海鸟卵的鸟窠上空盘旋……在世界的中心扎下根，透过灰黯的海水和水里瞬间的闪光以及倒影向上看去，这里是多么宁静啊——假如没有惠特克年鉴——假如没有尊卑序列表！

In the light of the paleoenvironmental significance reflected by the radiolaria, graptolite, brachiopod,sponge spicule and the rock character, its suggested that the greyish green mudstone at the basal WufengFormation of the Goujiaya section would be probably deposited in 60 to 100 meters deep water, theGuanyinqiao bed in 50 to 80 meters deep, and the radiolaria-bearing silicalite from Wufeng Formation inwater with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level changecycles, the change range of every one of the 5 cycles could be further conjectured.
