针对巴拿马运河当局对船舶吃水的要求和巴拿马型船的特点，阐述船舶在航行途中油、水消耗和舷外水密度变化引起船舶吃水、吃水差的改变，提出一种在装货港预置吃水差法以确保巴拿马型船顺利通过巴拿马运河的配载方法。经数十艘巴拿马型船营运证明，该方法是准确可靠的

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。

Shallow draft traffic, like barges and tow boats, and ship traffic with up to a draft depth of 39 feet, had already been cleared for navigation earlier last week, allowing some grain elevators to resume off-loading of barges and loading of ships.

像驳船和拖轮那样的浅吃水船只，和吃水低于39英尺的远洋货轮在上周早些时候已经通航，这使得一些谷物码头恢复了驳船卸货和远洋船舶装货作业。

The concept of air floating decrease coefficient was introduced and thecomputing method about correlative parameters and stability indications of staticstability were studied considering the geometry parameters, air pressure and differentdrafts. Based on the theoretical methods of the statics of the ship, computing methodon static stability of steel cylinder block is given, the stability properties of thestructure block made up of four steel cylinders whose diameter is 10.5m werecalculated under six kinds of drafts and different aeration heights, the initialmetacenetric height of the structure block was obtained, and the stability wasevaluated under different floating conditions.
