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。

Among his examples are vampire bats tuned to extract blood from large slumbering mammals and bats that aim instead for the warm breast plates of birds; New World leeches that track their hosts through the water and Old World leeches that relentlessly stalk down blood bearers on land; the notorious vampire finches of the Galapagos that daintily peck open dribbling wounds on the hindquarters of blue-footed boobies; and the candiru, tiny, eel-like catfish that are reputed to have the power to swim up a person's urethra and suck blood from the bladder and thus are often more feared than their fellow river dwellers, the piranhas.

他举的例子有自静止状态的大型哺乳动物吸血的吸血蝙蝠，与转而瞄准鸟儿温暖胸脯的蝙蝠；西半球的水蛭透过水来找寄主，东半球的水蛭在陆地上无情追踪带血的对象；加拉巴哥群岛恶名昭彰的吸血鸣鸟一点一滴优美地在蓝脚鲣鸟的尾部啄出伤口；还有短小鳗形的寄生鲶，以直接游入人类尿道从膀胱吸血而知名，因此比同条河里的食人鱼更令人畏惧。
