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。

And has brilliant prospect due to its simple structure, good economy and energy saving performance.Based on the full scale passive solar experimental building in DUT, in which the researcher carried experiment as the main method and the CFD simulation as the minor method, the research focuses on passive ventilation formed by the Trombe wall. This paper analyzed the indoor thermo and humidity performance of passive solar building with Trombe wall, and the different ventilation patterns in different seasons, revealing the role of passive ventilation in improving indoor environment. Also the paper researched the characteristics of passive ventilation on air flow and heat transfer mechanicsms, and put forward the best control and adjusting method. Meanwhile the paper gained an empiric formula in use of calculating the natural convection heat transfer and found the key factor of influing the indoor environment.

passive resistance:被动抗病性
这种先天的免疫力引起的抗病性为被动抗病性(passive resistance). 被动抗病性是植物与病原物接触的前已具有的性状所决定的抗病性. 植物直接暴露于空气中的细胞壁表面覆盖有一层生物聚酯膜、在未收到病原侵染前植物细胞中就含有各种不同类型的特殊化合物等就是被动抗病性的表现.
