The construction of the models is based on such theories as theoretical mechanic , advanced mathematics , space analytic geometry , the theory of ship and sea - keeping theory 文中选取的滚装客船船型是在渤海海峡滚装运输生产中最为常见的类型。
As with conventional ships , the methods of model experiment , theoretical analysis and numerical calculation are applied to predict the resistance of swath 和常规船型一样，预报swath船型的静水阻力可采用船模试验、理论和数值计算方法。
Chapter 4 computes the wave - making resistance , the 3d wave figure and its contour figure of wigley ship and makes satisfying results 第4章对wigley船型的线性兴波阻力、不同弗氏数下的三维波形和等高线图作了数值计算，也取得了令人满意的结果。
The results indicate : naval ships with built - up stabilizing appendage are not only full - navigating in the higher conditions , but improve the sea - keeping 结果表明，带减纵向运动组合附体的船型不但能在较高海情下全速航行，并可提高其适航性。
The full - scale swath model is established through every offsets . in addition to resistance results the wake distribution at propeller plan is also obtained 由各点的型值来建立模型，除了得到阻力方面的结果，还对该船型桨盘处的伴流分布做了研究。
Small waterplane area twin hulls ( swath ) is a kind of high performance ship with special shape which has been developed during last decades 小水线面双体船( smallwaterplaneareatwinhulls ， swath )是近三十年逐渐发展起来的具有独特船型的高性能船舶。
This paper presented a new type of triswach ( trimaran small waterplane area center hull ) with small length displacement volume ratio which has low powering requirements at high speed 摘要提出了一种阻力性能优良、船长排水量系数小的高速小水线面三体船型。
The first chapter states the significance of argumentations on what types of boxships to be deployed on the sino - japan trades through analyses of the trade activities between china and japan 文章第一章，通过对中日贸易的分析，阐述了中日航线船型论证的意义。
