14、 inconvenient in many cases since the ship is nowadays built up of large prefabricated units.A unit may consist of shell plating,some framing and part of deck.预制的预制的e.g.（P34-2-4）shell expansion 外板展开外板展开 plan 图，平面图 An expansion of a ships shell is given in Fig.3.2,showing the positions of the various

15、 units.Plans are therefore drawn in relation to units and contain all the information required to build a particular unit.图3.2给出了船体的外板展开图，图中显示了各个单元的位置。因此，图纸的绘制是和单元相关的并包含了需要建造一个特定单元的所有信息。e.g.（P34-2-7）classification society 船级社 A number of traditional plans are still produced for classification societ

16、y purposes,future maintenance and reference,but without the wealth of manufacturing information which is only needed on the unit plans.一些传统的图纸仍然为了船级社的要求，将来的维修和参考而绘制的，但是这些图纸没有只针对单元图的制造信息。e.g.（P34-3-1）chart 图表assembly 装配erection 装配 The planning and production control departments require drawing inform

17、ation to compile charts for monitoring progress,compiling programmes,producing programmes for material delivery,parts production and assembly and finally unit production and erection.设计和生产控制部门需要绘图信息来编制检测进展，程序编译，材料配送的生产程序，小部件的生产和装配以及最后单元的生产和装配。e.g.（P36-1-2）steel ordering 钢材预定 The steel ordering is a

18、key function in the production process,requiring involvement with the drawing office,planning departments,production departments and the steel supplier.The monitoring and control of stock is also important,since the steel material for a ship is a substantial part of a ships final cost.重要的重要的e.g.（P36
