The Yangtze river boats are one of the special type of boats in our country.For many years our shipbuilders have gained much experience and success in the design and construction.Their general arrangements and hull structures,have been carefully studied,with special attention to the narrow waters,rushing current,curved course and beaches etc.of the river.So,an excellent type of Yangtze river boats of light weight,strong structure,small draft,large cargo capacity,good maneuverability and high speed is needed.Besides,the depth of the river changes with seasons,the ship may be used all the year round. This paper is a summation of the building experience of five Yangtze river boats which were built during the period forward of 1958. The principal dimensions and characteristics of the five boats are: Length over all 71.20m.;Displacement 1376T; Breadth,max.15.00m.;Passengers and crew 544; Depth moulded 5.80m.;Speed 14 knots. The author analysed some of the key points of technical problems,which oceured in the building process and some conclusions are as follows: 1.The reasonable choice of the sectional positions is very important to the thin plating structure like the Yangtze river boats,the double bottom section of longitudinal system in general should be sectioned. 2.The measurement of pre-distortion is a ratter simple,economical and effective means for mini- mizing the welding distortion.This may be recommended to all sections,the value of predistortion may be chosen by experience or by calculation. 3.Joining the structure parts of the super-structures by the use of CO_2 gas protected welding may result less distortion and more production.The quality of the wavelike structure is closely dependent on the shape of the mold. 4.The shaft strut is positioned and assembled to the hull on the shipway after itself being complctep as a whole on the support mold floor.This was proved to be an advaneed technique by the building practices of the several Yangtze river boats.Since the assembly-time being cut to 1/3,and therefore the shipway time is shortened by this sequence. In addition,a few suggestions to improve the structures in further design are also made.These may be used as references for designing and construction of the same type of boats.

长江船舶是我国特有的一种船型。多年来,我国的造船家在设计和制造这种特殊船舶时取得了许多经验并获得了相当成就。如对船舶进行了合理的布置;有效地迭用和安排了船体结构。并考虑到江面狭窄、水流湍急、航道迂回曲折、险滩多等特点,选取了良好船体绕型,从而得到了:船体轻、结构牢固、吃水浅、载重量大、敏转性能好以及航速高的优秀的川江船舶。此外,因江水深度随季节变化甚大,故设计时应考虑“枯水”及“洪水”两种不同吃水,可以全年通行无阻。本文主要总结了1958年大跃进时制造的五艘同型川江客轮船体的建造经验,并作了全面的分析和探讨,并得出下列结论:1.送择合理的分段划分位置对薄板结构的长江船舶有着重要意义。纵结构的双重底分毀,除在起重能力受到限制外,一般应以环形划分为宜。2.焊接船体分段采取反变形来减少变形,这是既简单又有效的方法,值得在各分段上推广应用。反变形数值的送择可根据实践累积经验估计或理论计算得出。3.文内提出上层建筑的连接可广泛采用 CO_2气体保护焊,以减少变形、提高生产率。围壁的波形结构加工质量与模具形状有着直接关系。4.后艉轴支架采取在胎架上整体组成后,再到船台定位安装的方珐,经过几艘川江客轮的实践证明...

本文主要论述以下几点:1)西南地区至今为止已发现的志留纪三叶虫大致有30多个属,80多个种。2)较集中产出于两个层位,一是下志留统的香树园组至雷家屯组或与其相当的层位。另一是中志留统的秀山组。前者以翼斜视虫Ptilillaenus 为代表,后者则是以王冠虫Coronocephalus 为主的三叶虫组合。3)这两个三叶虫动物群组合除个别属种外,多数为我国特有,和其共生的笔石、腕足类等有的可与国际对比。4)区别王冠虫属和似彗星虫属在本区及邻近地区志留纪地层对比有一定意义。前者仅见于中志留统的秀山组,后者在我国自晚奥陶世至晚志留世的地层中都有发现。5)滇东关底组的东方棘尾虫Acanthopyge orientalis Wu及玉龙寺组的Warburgella rugulosa (Alth) sinensis Wu 的发现为滇东志留泥盆系的划分和对比提供了重要的三叶虫化石依据。6)系统描述彗星虫科的一些新属种。
