   低速运转气膜机械密封端面波度和锥度对其密封性能的影响
2. For the large torque ripple of inductance motor based on direct torque control , especially at a low speed , this paper proposes a new control strategy
   摘要针对基于直接转矩控制中的感应电动机在低速运转时存在较大的转矩脉动问题，提出了一种新的控制方法。
3. An analysis of the vibration displacement signal shows that when the spindle runs at medium and low speeds , the viration displacement signal well reproduces the milling force signal
   同时对主轴振动位移信号进行了分析，指出了主轴处于中、低速运转时，振动位移信号能很好地再现铣削力信号。
4. Generally speaking , for an injection diesel engine , the combustion noise is higher than the mechanical noise ; whilst the case is the other way round for a non - injection diesel engine
   一般直喷式柴油机燃烧噪声要高于机械噪声，而非直喷式柴油机的机械噪声则高于燃烧噪声，但是低速运转时燃烧噪声都高于机械噪声。
5. Traditional direct torque control uses two value torque regulator which makes zero voltage vector work long and make flux shape bad seriously and makes response time long when the speed of induction motor is very low or drops down quickly . in order to solve this problem the thesis puts forward a new way to use three - value torque regulator , when the motor speed is very low or drops down quickly , the contrary voltage vector is used instead of zero voltage vector and the between the stator flux and rotor flux is reduced quickly so that torque is reduced quickly and response time becomes shorter
   为此，本论文提出三点式转矩调节，这样当电机低速运转或给定转速突降时，不是加零电压矢量，而是加反方向的电压矢量，使定子磁链与转子磁链之间的夹角迅速减小，从而使电磁转矩也迅速减小，大大减小了调速时间，同时磁链值仍然保持基本恒定，输出比较稳定的电磁转矩，这在电机制动过程中非常有用。
