In order to approach the world level of shipbuilding,science within twelve years,it is necessary to survey the recent development in shipbuilding research of some leading maritime countries.This paper starts with stating the achievments of shipbuilding research work in this himdred years and steps taken by some leading countries for further development after the World War Ⅱ.Then it goes on to discuss the main achievments in the field of ship hydrodynamics and ship strength in recent years,and these are subdivided into the following headings: Ship hydrodynamics:(1)Systematic model testing.(2)Model-ship co-relalion, (3)Theory of wave making resistance,(4) Systematic testing of model propellers, (5)Propeller theory,(6)Cavitation,erosion,Singing of propellers,(7)Ship motion and seakeeping quality. Strength of ships: (1) Strength testing of actual ships and stress measure- ments on sea way,(2)Strength testing in model tank,(3)Problem of long superstructure,(4) Elastic and plastic strength of ship plating,(5) Ship vibration, (6) Materials for ship construction. This paper also gives an account of the preliminary achievments of the Chinese shipbuilding research work in respective fields and expresses the opinion that a great deal of amount of work is left to be done for the Chinese naval architects.Finally,the paper suggests that China must redouble her effort to construct her main shipbuilding research base equiped with instruments and apparatus of highest quality and to train the research experts as quick as possible.

为了在十二年内争取赶上世界的造船科学水平,就有必要对世界各国造船科学研究的发展,进行一番探讨。本文首先说明造船科学在百年来所起的作用,和二次世界大战后各国对造船科学研究的组织和发展。进一步探讨了二次大战后在船舶流体力学及船体强度学两方面的主要成就。并分以下几部份叙述: 船舶流体力学方面:(1)关于船型的系列试验;(2)关于船模与实船的换算关系;(3)兴波阻力理论;(4)推进器系列试验;(5)推进器理论;(6)推进器空泡、剥蚀、唱音等问题;(7)船舶运动和适航性。船体强度学方面:(1)实船强度试验和航行中应力测量;(2)船模试验池中的强度试验;(3)长上层建筑问题;(4)船体钢板的弹性塑性问题;(5)船体振动问题;(6)造船用材料问题。文中也涉及一些我国造船科学研究的初步收获,并说明我国在整个造船科学领域中还留着很大空白面。为了进一步发展我国的造船科学研究;建设主要的研究基地,充实仪表设备和培养研究人员是刻不容缓的事。

In the summer of 1974, an ancient junk of Sung Dynasty was excavated in Quanzhou Bay (known as Zayton Bay in ancient times), Fujian Province. This discovery is of archaeological importance, and of great value to the study of China's navigation history and the development of her ship-building in ancient times.Based on this discovery, the paper describes the characteristic form and struc ture of the Quanzhou ship. It's low block coefficient and midship section coefficient combined with its fine lines tend to overcome the disadvantage in speed resulted from the length-breadth ratio being too small. It's gentle ribband lines make it easier to bend the outside plank, and V-shaped section lines help to improve its seakeeping quality.The position and the form in joining the keel are well arranged. It is remarkable that its bottom is of double plating, it's side shell of triple plating, and lap joints are used alternatively with butt joints. This discovery provides a substantial proof to the description of Marco Polo, the famous Italian traveller, and to the investigation made by a Japanese scholar Kuwabara. The design that the ship is divided into 13 watertight compartments is in accord with Marco Polo's record. The advanced technology in shipbuilding and the development of rudder are also touched in this paper.Based on the statistic data of China's Shipbuilding in the past generations combined with the remaining demensions of the very archaic vessels, the paper draws an inference from the study of its stability, strength, cargo capacity and fresh.water capacity, and proposes in conclusion that the demension to be restored should be as follows:length of the ship 30m.breadth 10.5m.molded depth 5.0m.block coefficient 0.43.draft 3.5-3.75m.displacement weight 399-454 ton.

1974年夏,在福建省泉州湾的后渚港发掘出土了一艘宋代木造航海货船。这一重大考古发现,对研究泉州湾的海外交通史和我国造船发展史,都具有一定的价值。 本文结合这一发现,阐述了泉州古船的船型和结构特点。指出该船采用较小的方形系数和中剖面系数以及瘦削的型线,既可以克服长宽比过小对快速性带来的不利,同时平缓的斜剖线可使弯曲外板的加工工艺得到改善。V形的横剖线则有利于改善船的耐波性。 泉州古船龙骨连接部位的选择和连接形式的设计均较为合理。底部为二重板,舷侧为三重板,而且是搭接与平接结合使用。这一重要发现,为意大利杰出旅行家Marco Polo的记叙和日本学者桑原骘藏的考证提供了极充分的实物证据。特别是用十二道水密舱壁板将全船分隔为十三个舱的设计,与Marco Polo对中国船舶的赞誉是惊人的一致。文中对造船工艺的先进性和航的发展演变等问题,也进行了分析。 本文还根据我国历代船舶的统计资料,结合古船的残存尺度,从稳性、强度、货舱容积和淡水舱容积等各个角度,推论本船应有的尺度。作者对复原的建议是:船长30米,宽10.5米,型深5.0米,方形系数0.43,吃水3.5~3.75米,排水量399~454吨。
