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。

It expanded to 106119ha in 1973, descented to 99167ha in 1987, backed up to 112440ha, and attained the max value in history—123170ha in 1998 and descent to 109934ha again in 2001. GIS overlaying analysis shows that, the spatial change of Minqin Oasis had the different characteristics in different stage in the last 50 years: at the end of 50's to the beginning of 70%, oasis expandation Was performed by extension of origin oasis; the atrophia of oasis from the beginning from 70's to the 80's was performed by increasing of non-oasis spot pieces of inner part for oasis; the main performance of keeping on expanding of oasis from late 80's to late 90's is outside extension of Baqu oasis near the upper stream, with increased oasis area in interior of hungriness and increased area of non-cultivation in Huqu oasis in the north. From 1998 to 2001, opening up wideness in interior of hungriness continued, but hnngrinessization of oasis became worse. The oases in the Minqin Basin developed from small to large and back to small in terms of area changes, and from south to north then to south in terms of spatial changes.
绿洲分布图的GIS叠加覆盖分析表明,近50年来民勤绿洲的空间变化在不同阶段有不同的特征:50年代末至70年代初,绿洲扩展主要表现为已有绿洲的外延式扩大;70年代初至80年代后期的绿洲萎缩,主要表现为绿洲内部非绿洲斑块增加;80年代后期至90年代后期的持续扩展,主要表现为靠近上游的坝区绿洲向外围扩展和荒漠腹地绿洲面积的增加,而北部湖区绿洲弃耕面积不断扩大;98年至2001年,绿洲荒漠腹地的开荒还在继续,但湖区的绿洲荒漠化还在进一步加剧。50年来民勤绿洲的发展总体上经历了一个面积由小到大再到小,空间位置上从南而北再向南的迁移过程。
