- n．q轴：在电机控制中，q轴是与磁场定向控制相关的虚拟轴，与d轴垂直，通常用于表示与磁场垂直的电流分量。
1 ?交轴 (d-axis)及交轴(q-axis)的电流控制准确度，其控制参数变动所产生电流误 差也就无法修正。

The mechanic-electrical dynamic performance is determined by q-axis sub-system, and the voltage regulation performance is determined by d-axis sub-system. 机电动态性能由机电-交轴子系统所决定，电压调节性能由直轴子系统所决定。 - 2
If we have a solid cylinder, then the moment of inertia about this axis Q through the center of mass, which I've called Q, equals 1/2 MR squared. 假如有一个实心圆柱体，轴心的时间惯量,通过这个物质的中心，等于1/2，MR的平方。 - 3
No significant differences were found in the heart rate, QRS intervals, Q T intervals, sinus bradycardia, sinus tachycardia and left axis deviation between exposed and control groups ( P >0 05). 其余心率、QRS间期、Q-T间期的数值以及窦性心动过缓、窦性心动过速和心电轴左偏等发生率，两组之间均无差异（P＞0．05）。
