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。

The result indicated that, although microorganism from paddy soil could directly reduce Cr, the reduecing rate and efficiency were limited; the higher Cr concentration was, the less reducing ability the microbial showed; the microbe from different paddy soils had different effects on Cr reducing abilities; The reducing ability of the microbe from Sichuan paddy soil was higher than that from Jiangxi paddy soil. Cr added could be rapidly reduced in paddy soil under anaerobic incubation, moreover, the process of dissimilatory iron reduction of soil could obviously promote the Cr reduction. The existent of Cr could delay the appearance of Fe; the higher Cr concentration was, the later Fe appeared. The delayed time of Fe appearance was in accordance with the ending time of Cr reduction.
结果表明,由水稻土中提取的微生物虽然能够直接还原Cr,但其还原速率和还原程度有限,且Cr浓度越高,微生物的还原能力越差;不同来源的上壤微生物对Cr的还原能力有所差异,其中四川水稻土中微生物对Cr的还原能力均大于江西水稻土;在厌氧培养的水稻土中,添加的Cr可以较迅速地还原,其中土壤氧化铁的微生物还原过程对Cr还原具有明显的促进作用;Cr的存在导致Fe生成的时间出现滞后,目Cr浓度越大生成Fe的滞后时间越长;Fe产生滞后的时间与Cr还原结束的时间具有一致性。
