由运算符—通常和您在正则表达式中看到的符号相同—来指定小部件在较大的部件中出现的频率和顺序。
The frequency and order in which small parts may occur in larger parts is specified by operators — mostly the same symbols you see in regular expressions.
部件类型—由分类符号B指定。
制造的部件的目标机器名称—由分类符号M表示。
Machine name for which the part is manufactured - Donated by classification symbol m.
部件制造商名称—由分类符号R指定。
Part manufacturer name - Designated by classification symbol r.
制造部件的地点—由分类符号P指定。
Place where part is manufactured - Designated by classification symbol p.
图12显示了结构图的变化，即端口、部件与ball和socket符号。

图纸内容还应包括材料部件编号，间隙公差，表面机械加工符号，热处理信息，表面保护，材料重量，以及其他的必要内容。
Drawings will also include the material part Numbers, tolerances clearances, surface machining symbols, heat treatment information, surface protection, material weight and other necessary information.
我们在封装标签的NoteBook窗口小部件中使用pageconfigure函数来完成这一任务，传入的第一个参数为被引用的标签的符号名。
We do this using the pageconfigure function on the enclosing NoteBook widget, passing the symbolic name of the referenced TAB as the first argument.
