But look carefully, there are no lurches, pauses, hitches or dead spots in their stroke technique - they have excellent rhythm and timing, moving seamlessly from one phase of the stroke to the other.
但仔细观察，就会发现在他们的划水技术中，没有踉跄，没有暂停，更没有被钩住和死点——他们拥有优秀的节凑和时机，正无缝地从一个相位转到另一个相位。
The brushless DC motor has excellent characteristics of good start and timing performance, but it is a nonlinear system owing to commutation process and armature reaction.
虽然无刷直流电机具有良好的启动和调速性能，但是由于换相以及电枢反应等因素，它属于非线性系统。
