This paper examines the soil characteristic and liquefaction degree of hard shell seams at the subaqueous delta of the Yellow River. Four typical areas were chosen for measuring, testing and studying. The hard shell seam strength was measured by in-situ Proctor penetrometer. Undisturbed soil sample of 1 m long was excavated for laboratory soil property test. Sledge hammers were dropped down freely to hit the load board to simulate the wave force acted on the hard shell seam. The excess pore pressure and strength variation were observed. The liquefaction depth of the hard shell seams at four study areas under different wave storms were calculated by theory.

为揭示黄河口水下三角洲硬壳层的土性特征和风浪作用下的液化破坏状况，选择典型研究区，在现场利用普氏贯入仪测试硬壳层的强度特征，原位取1m原状样进行室内土工试验；利用重锤锤击荷载板的方式模拟波浪对硬壳层的动力作用，通过孔压探头和普氏贯入仪实时监测土体内孔压和振动前后强度的变化；通过理论计算研究硬壳层在不同风浪等级下的液化深度。

The imaging quality of this lens was evaluated. The results show that it has an excellent imaging quality, at spatial frequency of 42lp/mm, its MTF value is greater than 0.5 for 0.7ω, and it meets all the specifications and requirements of WFOV and large relative aperture for underwater photographic application.

质量评价结果表明：设计的摄影物镜成像质量优异，在空间频率为42lp/mm时0.7ω的MTF值高于0.5，且达到各项性能指标，能够满足水下微光摄影物镜对大视场大相对孔径的需求。

If you were to try to create a sinuous underwater motion drawing by hand, it would be quite an arduous task, but on a computer you can set a couple key frames and cycle it, and you are done.

如果你尝试用手绘的方法制作一个复杂的水下动作，这将是个相当艰巨的任务，但在电脑上，你只需设置几个关键帧并让它循环，这个动作便完成了。

In the underwater laser image there are always speckle noise which is caused by backscattering of water.

水是一种特殊的介质，在激光水下图像中总存在因水的后向散射引起的散斑噪声。

For this tutorial I decided to make sharp reefs in the water … but you can use the same technique for anything stoney .

在这个教程中我想要绘制一个有着锋利棱角的水下暗礁。但你能用相同的技术来构造其他石头类的物体。

In sedimentology, sediment cores collected from the depocentre of the subaqueous delta show a trend of decrease in accretion rate over the last 30 years, representing the effect of catchment sediment discharge changes.

在沉积响应上，来自长江水下三角洲沉积中心的柱状样显示出沉积速率自下而上减小的趋势，反映了流域输沙率变化的影响。

The effect of thermal conductive coating on the thermolysis property of LED lamps with different color and packing number used in a close under-water environment was studied.

1引言散热是限制发光二极管功率提高的主要因素之一[1~9]。特别是在一些特殊和恶劣环境，如水下密闭环境下使用的大功率LED灯具的散热尤为突出。

Under the technology support of GPS attitude determination and tide surveying, the accuracy of depth determination can be got RMS 0.141m to relative to traditional method of bathymetric surveying.

In the basis of the facies markers and facies analysis of principle, there are mainly river、delta and lake depositional sysytems in Upper Triassic of Nanniwan field,in which all kinds of difference sedimentary subfacies and sedimentary microfacies are distinguished, such as meandering river、delta plain、delta front、submerged distributary river course、frontal sheet sand and so on.

利用收集到的各种相标志和相分析原则，对研究区的沉积相进行了比较细致的研究，将南泥湾探区上三叠统分为河流、三角洲、湖泊三种沉积体系，并在各沉积体系中细划出曲流河、三角洲平原、三角洲前缘、浅湖等沉积亚相和水下分流河道、河口坝、前缘席状砂等沉积微相。
