The floating gates, which have a hollow cavity inside, work according to Archimedes' principle of buoyancy. When compressed air is pumped in, emptying the gates of water, the buoyancy of the giant panels will be greater than their weight, and in just 30 minutes the barrier will float above the surface. The gates are attached to the seabed with hinges, which are designed to absorb the force of waves and keep the barrier in place. The gates will only be raised when waves are higher than 1.1 meters, to reduce interruption of the sea currents to a minimum.

这些中空的水闸门，主要依照阿基米德浮力原理操作，当闸门内注入高压空气排水后，闸门受到的浮力大於闸门重量，只要三十分钟就能浮出水面，闸门底部则用轴承固定在海底，再透过细部结构设计能够悉受波动力量，保持闸门的稳定性，而水闸门只有在浪高超过110公分的时候才会升起，把对海水交换的干扰降到最低，其他维护潟湖生态的措施也获得欧盟肯定，所以在2009年4月，取消摩西工程违反自然保育法的决议。

The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.

聚氧活化曝气增氧机采用磁性工程技术，将空气中的氧经聚氧器聚集活化后送到水下主机的混合室，由水下的磁化器和活化富氧空气快捷完成水气合成程序，在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡，这些随射流、射向水下方的小气泡，其动能消耗至零后，在水中的浮力作用下、开始缓慢上升，由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升，这些小气泡在短时间很难浮上水面，因此延长了小气泡在水中的停留时间和行走路程，大大提高水中溶解氧的效率，使该机的动力效率明显高于传统曝气装置。

The numerical results indicate that the operator splitting method effectively suppresses numerical oscillations in the cases of high air bearing number. The numerical results show that both air lift force and pitch moment increase with the ratio of the slider's rail height to the air film characteristic height and the air bearing number, and finally reaches to stable value.

比较在不同轴承数下的气浮力和纵倾力矩发现：同一轴承数下，气浮力随气膜特征厚度减小而增加；当磁头槽台高度与气膜特征厚度的比值相同时，气浮力随轴承数增大而逐渐增加直到达到某一值后保持不变；纵倾力矩随轴承数增加而增大到某个最大值后减小。

Then, a series of successful numerical simulations on the finite length inclined positively buoyant jets in uniform cross flows environment are developed. Based on the results from numerical simulations, some qualitative pictures of the complex three -dimensional mean flows are given. In terms of these pictures, the flowing behavior of the buoyant jets and the mechanism of end-vortexes generation are made a study.

This extra buoyancy is called reserve buoyancy;or,to be exact,the resever buoyancy which is measured by freeboard refers to the watertight volume of hull above load line.

这些保留的浮力被称为剩余浮力或者精确的说，剩余浮力是就是干舷至船体水线以上的高度。

Instead, one sculls the hands back and forth near the surface. The legs and feet are making similar movements. This results in the production of lift, which in turn keeps the swimmer's head above water.

实际上，常见的动作是手从靠近水面处的位置上下移动，腿和脚的动作也相似，这样，浮力产生了，这个浮力就可以帮助把游泳者的头部维持在水面之上。

That is why some hydrophobic ingredients should be added in order to made floating tablet with ideal floating duration other than decreasing the tableting pressure alone.According to the eroding kinetics, the floating tablet made of HPMC with greater viscosity as K100 MCR and K15 MCR is better than that made of HPMC E 15 LV. The erosion of the tablet made of HPMC E 15LV followed the first order kinetics. 20% of the tablet eroded with 4 hours which is 22 times that of the tablet made of HPMC K 100 MCR. The fast erosion of the tablet made of HPMC E15 LV led to quick buoyancy decrease. The quick swelling of floating tablet made of CMC-Na led to quicker water uptake.

溶蚀动力学表明，以高粘度HPMC K100MCR和K15 MCR制备的漂浮片，其漂浮性能要优于低粘度的HPMC如E15-LV，后者的溶蚀符合一级动力学规律，4小时内片面溶蚀达20％，溶蚀速度比前者大22倍，由于速度太快，漂浮制剂的漂浮力因此会迅速降低；高分子材料CMC-Na制备的漂浮片，虽然遇水后迅速膨胀使体积增大，但是，由于水渗入的速度大于体积膨胀的速度，因此不能产生足够的浮力和维持理想的持续浮力，另外，这种材料制备的漂浮片的溶蚀速度太快，4小时内片面溶蚀达30％，漂浮制剂的漂浮力也因此会迅速降低。

The results show that the increase of the buoyancy force by increasing the diameter and length of buoyancy modules is favorable for improving the static performances and reducing the requirements for the top tension of the riser, but arranging the buoyancy modules on lower joints of riser string can lead to hard operations of hang off, installation and retrieval of the riser, there fore the arrangement of buoyancy modules and slick riser joints should be considered carefully.
