阻力与动力在浅水中,水由船首流至船底而受限制主流由三向变为二方向,此时水流向后部流较为困难,船首前之水压力因而增加,使水积高而成一横波之峯,船之速度增加船身与斜波(divergent wave)所成之角渐渐增大,当船速到达一种水深之临界速率时最后成为90度,与横波(Transverse wave)相合,此二波之合不仅增加船之阻力逐渐变大,且将船首推起,使船尾自然下沉。当船之速率增加船尾下沉愈甚,船尾下沉愈甚,阻力
Resistance and motivation In shallow water, the flow of water from the bow to the bottom of the ship is limited, and the mainstream is changed from three directions to two directions. At this moment, the flow of water to the rear is more difficult. The pressure of water in front of the bow thus increases, resulting in a high shear rate The ship’s speed increases. The angle between the hull and the divergent wave gradually increases. When the boat speed reaches a critical depth of water depth, it finally becomes 90 degrees and matches the transverse wave. The combination of waves not only increases the resistance of the ship gradually becomes larger, and the bow thrown, so that the stern naturally sink. As the ship’s rate of stern sank even worse, the stern even worse, resistance
