机械制图中10js9是什么意思？

表明基本尺寸为10mm，公差带代号js9，字母小写，表明是外表面（轴）配合尺寸，上偏差值+0.018mm，下偏差值-0.018mm。

js9一般使用在键槽配合中，属于过渡配合。

尺寸的公差指允许尺寸的变动量。

公差带图是为了方便表示两个互相结合的孔、轴的公称尺寸、极限尺寸、极限偏差与公差质检的关系（图1）。公差带是在公差带图中，代表上极限偏差和下极限偏差或上极限尺寸和下极限尺寸的两条直线所限定的一个区域，称为公差带（或尺寸公差带）。它是由公差大小和基本偏差来决定的。

图1 公差带示意图

js有点难度的问题

这种东西关键就是函数名和参数什么的最好别重名
