起动

At the same time, along with the increment of cities' railway transportation, it isharder and harder for the traditional protection equipments to distinguish the remote shortcircuit fault or the train starting correctly, especially for the fault with electricity arc ortransition resistance. This always results in the equipment operation time longer that it can'tcut off the short fault rapidly.

同时，随着城市轨道交通系统运量的不断加大，传统的保护装置越来越不能正确可靠地区分远端短路故障状态与机车起动状态，尤其是当发生远端电弧故障或经大过渡电阻故障时，往往造成保护动作时限加长。

During the starting and lowspeed range, the stator windings are shortcircuited and the DFIM system is operated in variable frequency drive mode supplied by rotor side; in highspeed range, the motor works in doublyfed mode, so wide variable speed range can be achieved.

该系统在起动和低速段将定子绕组短路，转子侧采用变频调速运行方式，在中高速段则采用双馈调速运行方式，从而实现了双馈系统在宽转速范围内的平滑调速。

When the device just starting when the low-temperature condensed water pipe occurs, double metal film is flat, and the elastic spring heart valve, the valve in the open position.

当装置刚起动时，管道出现低温冷凝水，双金属片是平展的，阀心在弹簧的弹力下，阀门处于开启位置。

On the basis of the modeling and analyzing of the transmission system of the PQS-3-D elevator for car in the preamble, this article analysis the reason of the small difference of the angular speed, angular acceleration, angular displacement curve between the bilateral symmetry components. Actually, it is the result of that the torsional rigidity of the bilateral drive shafts are different, therefore has made the revision suggestion to the drive shaft parameter.

在对PQS-3-D型汽车专用升降机传动系统建模分析的基础上，分析左右对称传动构件的角速度、角加速度、角位移曲线在系统起动时间内有较小差异的主要原因，发现是由于左右传动轴的扭转刚度系数不同造成的，故对传动轴的参数做了修改建议。

Objective To develop a low temperature catalyst for the Sabatier CO2 reduction of the atmospheric regeneration system and lower the start-up temperature of the Sabatier reaction.

目的 研制用于大气再生技术Sabatier二氧化碳还原反应的低温催化剂，以降低Sabatier反应的起动温度。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
