我国在船舶建造质量日益提高的情况下,内河船舶也逐渐采用国外正在广泛使用的公差造船,并日益在造船界得到推广。这就要求对船舶的每一个零部件加工、装配制订一个既先进又切实可行的公差标准。 In our country, with the increasing quality of ship construction, inland vessels are also gradually adopting shipbuilding which is widely used abroad and are increasingly being promoted in the shipbuilding industry. This requires the development of an advanced and practical tolerance standard for the processing and assembly of every part of the ship.
