而我请高手分析了一下，就能看出不是被降权了，做了一些外链坚持更新网站内容很快就恢复了。
And I asked ace to be analysed, can seeing is not authority be fallinged, did a few outside catenary insists to update website content to restore very quickly.
在没有电力资源的情况下，既要解决循环链梯缓降速度，实现平滑控制的问题，又要解决系统长期处于闲置状态，而不影响其可靠性的问题。
When there is on electrical power, slow descending control of circular chain ladder as well as to assure the reliability in use when set aside for a long time has to be solved.
提出一种估计异步电机转子速度和转子磁链的新型降阶推广卡尔曼滤波器算法，建立了基于此算法的异步电机无速度传感器矢量控制系统。
A speed sensorless vector control system of induction motor with estimated rotor speed and rotor flux using a new reduced order extended Kalman filter is proposed.
有效的降凝剂基本都具有长烃链和极性基的聚合物。
Almost all effective depressants contain long hydrocarbon chain and polar polymer.
传统的直接转矩控制采用六边形磁链控制或六区间的圆形磁链控制，造成转矩脉动大，而且当考虑定子电阻压降的影响时，其区间选择存在缺陷。
Traditional DTC uses hexagon flux control or six-section circle-flux. When the voltage of stator resistance is considered, its section choice has defect.
