摘　　要：根据船池模型试验,对双体船的航速从亚临界速度区至超临界速度区的全过程产生的船行波的变化规律进行研究。指出影响船行波波高的主要因素是深度佛汝德数,其变化规律与船舶的兴波阻力的变化规律相似。文中侧重研究了双体客船以快速(即航速大于临界速度)航行时产生的船行波波要素的变化规律及波高向岸边传播的衰减,给出计算船行波波高及其衰减和波周期的经验公式。On the basis of ship model basin test, the variation law of ship wave ofcatamaran produced in the whole process from subcritical speed zone to super-critical speed zone is studied. It is pointed out that depth Froude Numberis the main factor affecting height of ship wave, the variation law of whichis similar to that of drag force. It is also studied emphatically that whencatamaran navigates at fast speed (i.e., navigation speed is greater than cri-tical speed), variation law of ship wave factors and attenuation of waveheight from centre to bank, and empirical formula for calculating height ofshipwave,its attenuation,as well as wave period are given.
