Faraday's law is that when the flux in the conductor loop changes, it produces electromotive force in the conductor loop, and obeys to contour integral law , Maxwell Curl Theory is that when the magnetic intensity of a certain point in ether space changes, there produces electric field at that point in ether space, which is the field mutual production theory of "electric field produces magnetic field and magnetic field produces electric field" in the free space which everybody is familiar with, and it obeys differential law , Lorentz magnetic force is that when metal electrons cut magnetic lines, metal electrons forced by move along the conductor to form inductive current, in fact, it doesn't matter whether coil moves or magnet moves, only if there exists relative motion between magnetic field and conductor, metal electrons must cut magnetic lines, which is,"coil stills while magnet moves to the left" and "magnet stills while coil moves to the right" these two situations are the same, which both belong to metal electrons having cut magnetic lines.
法拉第定律指导体环路里的磁通量发生变化时,在导体环路上产生电动势,而且服从围线积分律;麦克斯韦旋度理论指以太空间某点的磁场强度发生变化时,在以太空间的该点产生电场,即大家熟知的自由空间里"电场生磁场与磁场生电场"之互生场理论,而且服从微分律;洛伦兹磁力指金属电子切割磁力线时,金属电子受力沿着导体漂移而形成感应电流,其实,无论线圈运动或是磁铁运动,只要磁场与导体存在相对运动,则金属电子必然切割磁力线,即,"线圈静止而磁铁向左运动"与"磁铁静止而线圈向右运动"这两种情况是一样的,都属于金属电子切割了磁力线。

所有年龄所有高度的竹材微密度从竹青到竹黄对材性变异规律如下:从竹青到竹黄开始下降梯度较大,一般到相对竹皮距离0.35左右处(整个竹壁厚度为1),竹材微密度下降梯度减小,微密度的变化范围变小,到近竹黄处,微密度达最小值,而后到竹黄部位密度大幅上升,竹材最小密度一般只有最大密度的50%或更低,竹黄由厚壁的石细胞组成,所以密度较大,一般比最小密度增大约50%-100%,厚度较薄,不同年龄不同高度竹材的竹黄厚度相差无几,约在0.8mm左右;竹材从1度竹到2度竹生长过程中,平均密度的增长主要发生在竹肉部分,从3度竹到4度竹生长过程中,平均密度的下降主要发生在竹肉部分,同一年龄同一高度,竹壁厚径向的密度梯度越小,力学强度越高,随着年龄的增大,密度梯度越来越小(1度竹除外),随着高度增加,密度梯度越来越大。

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。
