In each cylindrical section (measuring cylinder) coaxial with the datum axis a, the section line shall be contained between two circles 0.1 apart and perpendicular to the datum axis a.
在每一个与基准轴a同轴的圆柱面内(测量圆柱)，该截面线应包含和基准轴相距0.1两个圆圈之间。
2
The design adopted coaxial twin spindles configuration and passive annular-cylinder.
该主轴系统采用了同轴双套主轴结构及无源环形油缸设计。
3
Therefore when designing cylinder, the coaxial degree of the cylindrical surfaces of hydraulic cylinder must be restricted.
