The analytical method of angular power spectum for averaged field in shallow water is based on the Ray-mode theory. By introducing the concept of the averaged angular power spectrum, some calculation for transmission less, long-range reverberation and spatial coherence will be simplified. The range and depth dependence of the long-range reverberation and echo-reverberation ratio were calculated for the cases of negative gradient and homogeneous layers. It is shown that, for the long-range detection in an inhomogeneous...

The analytical method of angular power spectum for averaged field in shallow water is based on the Ray-mode theory. By introducing the concept of the averaged angular power spectrum, some calculation for transmission less, long-range reverberation and spatial coherence will be simplified. The range and depth dependence of the long-range reverberation and echo-reverberation ratio were calculated for the cases of negative gradient and homogeneous layers. It is shown that, for the long-range detection in an inhomogeneous layer, the variable depth sonar is better than the sonar in constant depth. The method and results would be useful for analysing angular and frequency dependence of the bottom (or surface) scattering at low grazing angles.

浅海平均声场角度谱分析法以Ray-mode理论为基础。引进平均声场角度谱的概念以后,可使浅海传播衰减、远程混响和空间相关等平均特性的一些计算变得较为简单。用该法在浅海负梯度和均匀层情况下,计算了远程混响和回波、混响比的距离、深度结构。理论证明,在非均匀层浅海远程探测中,深度可变声呐比固定声呐有较为明显的优越性。本方法和结果将有助于分析小掠角海底(面)散射的角度、频率依赖关系。

The intruding, moving and depositing of the turbid density flow produced at the junction of a river and a canal or of a river and an approach channel to a lock is discussed in detail in this paper. It is supposed that such density flow can be reduced to a steady one with varing discharge and constant depth along the distance. The equations of Energy momentum,and balancing of the sediment transportation are derived theoretically. By solving these equations, a set of formulae for the entrance velocity ν,...

The intruding, moving and depositing of the turbid density flow produced at the junction of a river and a canal or of a river and an approach channel to a lock is discussed in detail in this paper. It is supposed that such density flow can be reduced to a steady one with varing discharge and constant depth along the distance. The equations of Energy momentum,and balancing of the sediment transportation are derived theoretically. By solving these equations, a set of formulae for the entrance velocity ν, the depth h, the point velocity νand the point concentration S of the flow are obtained. A calculating method for the amount of the depositions is suggested. The results of the calculation are in good agreement with the practical measurements. It is seen that the method suggested can be used to solve special problems treaded in this paper.

本文讨论了河渠以及河道与船闸引航道汇口处异重流的发生、入侵、运动和淤积问题。浑水异重流的运动可以认为是恒定均匀变量流运动.文中通过分析,提出了描写此种运动的一元能量方程、动量方程和输沙平衡方程.从上述方程导得异重流的进口速度v_0,深度h,异重流速度v的沿程变化公式和含沙量S沿程变化公式,进而提出了异重流淤积量的计算方法.该方法的计算结果,与实测淤积成果相比较,获得了较好的验证,表明此方法可用于这类工程的异重流淤积量的计算.

The linearized porous wave maker theory presented by Chwang [1] was applied to obtain the free surface wave profiles produced by vertical non-porous end plate and vertical porous plate in the vicinity of the end plate both or only one of them doing small amplitude piston type movement in a semi infinite constant depth channel. The influence of the dimensionless porous effect parameter G on wave profile is studied, when the dimensionless wave effect parmeter is a constant. It is found that when the distance between the two plates is a multiple of the half-wavelength of propagating surface waves, the "wave-trapping" phenomenon and "wave-invariability" phenomenon will occur. The possible resonances are discussed. And the experiment is done to verify the theory.

本文应用Chwang提出的线性透水造波机理论,求得了有限水深、半无限长渠道中,其一端的铅直不透水板和该板附近的铅直透水板作活塞式运动的几种组合情况所产生的自由表面波的波形,并对当无量纲的波的影响参数C一定时,无量纲孔隙影响参数G对波形的影响进行了研究。我们发现,当两板间距为表面行进波半波长的倍数时,将出现波的陷井现象或波形的不变性现象,并对可能出现的共振现象进行了讨论。通过实验对所提理论进行了初步验证。
