英语翻译
A tolerance is designated by a letter (in some cases,twoletters),a symbol,and a numerical
symbol.Capital letters are used for holes and smallletters for shafts.The letter symbol indicates
the position of the zone of tolerance in relation to thezero line representing the basic size.The
numerical symbol represents the value of this zone oftolerance and is called the grade or quality
of tolerance.Both the position and the grade oftolerance are functions of the basic size.A size
with tolerance is thus defined by its basic valuefollowed by a letter and a number
In engineering drawing practice,the tolerance for holeand shaft is written a little above and
little below the basic size,respectively.[3]Similarly,afit is indicated by the basic size common to
both the mating components,followed by the appropriatesymbols corresponding to each
component

有些专用词不太熟,试着翻一下大概意思吧,
公差用一个字母（有时是两个）,一个符号和一个数值来标示.大写字母用来标示孔,小写字母被用来标示轴.字母符号指示出同代表基本尺寸的基准线有关的区域位置,数值符号代表公差的区间值并被称作公差等级或公差特性.公差位置和公差等级都是基本尺寸的函数,带有公差的尺寸就这样被它的基本值并后跟一个字母和一个数字决定了.
在工程制图的实践中,孔和轴的公差被分别标注在基本尺寸的上面一点儿和下面一点儿.同样地,配合尺寸由配对部件的公共部分的基本尺寸所表示,后跟对应每个部件的合适的字符.
