1987年和1988年两年来，对具有单个或多个前壁的狭缝型吸波器的波反射和它的复氧能力进行了研究。研究内容如下：1.单、双前墙狭缝式消波装置狭缝对波浪反射及水质点速度之研究。2.前壁数对狭缝式消波器狭缝中水质点速度的影响。3.狭缝型吸波体反射波的尺度效应研究。4.开发一种能在较宽频率范围内有效耗散波浪能量的狭缝式吸波器。5.不规则波作用下狭缝式吸波体的波反射分析。6.缝型结构周围波动特性的数值分析。7.单壁或多壁狭缝式吸波体复氧能力的研究通过上述（1-6）的研究， ...更多信息 具有任意数量的前壁或安装在土墩上的狭缝型结构的水力特性（例如波浪反射）可以在理论上变得清楚。此外，模型的比例尺或不规则波的特性的影响，可以清楚。因此，本文提出的理论可以正确地计算出狭缝式消波器设计所需的尺寸，即使波浪反射最小的最佳尺寸。在此基础上，作为研究的最后阶段，作者对狭缝式消波器的复氧能力进行了模型试验。试验结果表明，复氧系数（k_2）强烈地依赖于通过狭缝的水颗粒速度，而与狭缝前壁的数目无关。应指出的是，这一结果尚未被现有的研究所指出，现阶段必须分析的一个课题是获得一个表达式，用它来评价狭缝型吸波材料的复氧能力。少

Studies on the wave reflection of a slit type wave absorber having single or plural front walls and on the reaeration ability of it have been studied for two years of 1987 and 1988. The contents of the studies are as follows: 1. A study on the wave reflection and water particle velocities through slits of a slit type wave absorber having single or double front walls. 2. Effects of the number of the front walls on the water particle velocities through slits of a slit type wave absorber. 3. Studies on scale effects on the wave reflection of a slit type wave absorber. 4. Development of a slit type wave absorber effectively dissipating wave energy for wider frequency range. 5. An analysis of the wave reflection of a slit type wave absorber under irregular wave action. 6. A numerical analysis of the wave behaviour around a slit type structures. 7. A study on the reaeration ability of a slit type wave absorber having single or plural front walls.Through the studies(1-6) mentioned above, the … More hydraulical characteristics such as the wave reflection of slit type structures having any number of front walls or being installed on a mound can be made clear theoretically. Also, the effects of model scales or of irregular waves on the characteristics can be made clear. Therefore, dimensions required for design of slit type wave absorber, say, the most preferable dimensions of them to minimize wave reflection, can be correctly evaluated by a theory presented herein.On the basis of the fruits, and as the final stage of the studies, the authors performed model tests on the reaeration ability of a slit type wave absorber. The tests show that the reaeration coefficient(k_2) depends strongly on water particle velocities through slits regardless of the number of the front walls of them. It should be noted that this result have not been pointed out by existing studies.A subject which has to be analysed at the present stage is to obtain an expression by which the reaeration ability of slit type wave absorbers can be evaluated.
