与waterline相关的网络例句 [注：此内容来源于网络，仅供参考]

When the gas flux is constant, the ratio of reduced resistance is improved with the increase of the water stream velocity. However, the relationship between the gas flux and the ratio of reduced resistance is more complex. When the water stream velocity is constant, if the gas flux is small in contrast, the effectiveness of reduced resistance is not obvious. But when the gas flux increased, the jetted gas will form """"archform"""" which will augment the shape resistance. In this condition, resistance could not be reduced and could even be increased, if the gas flux continues to be increased. So that there needs setting a baffle called step, which introduces the jetted gas into the turbulence boundary layer. In this case, the shape resistance may be fairly great. Besides, the waterline of model has also some effect on the ratio of reduced resistance, which acts on the size of wave. If waterline is deep, the wave could not affect the deployment of microbubble layer, so there is almost no effect on ratio of reduced resistance. However, the wave would affect distributing of microbubble layer under the model so that the gas could leak out from the two sides of model and directly affect the ratio of reduce resistance if the waterline is very small. Whether installing the dashplate or not has also the great influence on the effectiveness the ratio of reduced resistance. From the results of experiment, conclusion is that adding dashplate will greatly improve the effectiveness of reduced resistance.

当喷气量一定时，水流速度增大，减阻率提高；喷气量与减阻率之间的关系比较复杂，速度一定时，如果喷气量较小，减阻效果就比较差，但当喷气量增大的话，喷射出的气体就会形成一个&拱度&，增加了船模的形状阻力，在这种情况下最好采取断阶喷气，把气体引入到湍流边界层中，在这种情况下，船模的形状阻力比较大；船模的吃水对减阻率也有一定的影响，主要表现在波浪大小上，如果吃水较深，波浪影响不到微气泡层的分布，对减阻率不会造成太大影响，如果吃水较浅，波浪就会影响到微气泡层在船模底部的覆盖情况，可能会有部分微气泡从船模两侧泄漏，这样就直接影响到了减阻效果；是否安装压浪板，对减阻率也有较大的影响，从试验结果可以看出，在船模尾部加设了压浪板时，减阻效果明显得到改善。

Under the condition of different velocity of downstream.flux、waterline and so on, the conclusioti drawn from the experiment 'isthat the ratio of reduced resistance is relevant with the velocity of thedownstream and the jetted gas' the waterline of model and the dashplate.

通过不同来流速度、不同流量以及不同吃水等情况下的试验，结果表明：减阻率与来流速度、气体喷射速度、船模的吃水以及有无压浪板有关。

The research of this thesis is under the circumstances that the international shipping center of Shanghai builds Yangshan deep water port project, first of all, through its SWOT analytical method analyze Shanghai maritime affairs situation, maritime affairs office existing boat policy, Yangshan deep water port hydrometeorological situation, analyze the present main ship type, to explain the background of the choice the ship the small waterline, to put forward the necessity of building small water-plane area twin hull maritime affairs patrol ships. Then, it introduces the principle, characteristic of the small waterline, and has analyzed the domestic and international state of development of the SWATH ship, and conclude that it is feasible to build SWATH maritime affairs patrol ship technical, through the research and analyze of design at home and abroad,; Then it analyzed the application of the SWATH ship in maritime affairs manage both at home and abroad, put forward the preliminary scheme, and carry on research to the economic performance of technology of the scheme, through putting forward the preliminary model of plan of design to main yardstick and selecting type of host computer finally after relatively optimize, and confirm design specifications .
