To meet this need , in recent years , scientists have introduced the micro / mini internal combustion engine into the micro / portable power generation systems 为了满足这种需求，近年来，科学家们已经开始研究利用微型/小型内燃机作为微型/便携式发电系统原动机。
Take up with your engineering people to give us manufacturing drawing of protion of car body where it joins with side frames 拖车将被分成俩部分，在两个侧面连接到底座上，在任一原动机的牵引下进行移动。通过这种方式，起重机就可以自行行走而不需要额外的拖车了。
To prescribe in regulation 44 the specific measures required to effectively guard a prime mover , transmission machinery and dangerous parts of other machinery used in construction sites 为第44条订明在建筑地盘内使用的原动机、传动机械及其他机械危险部分的有效防护措施。
Keeping the drilling rig competitive meant fast moves between locations , a demand which saw the unitization of prime movers with rig components and sectionalized rig equipment for speedy handling 原译：使钻机保持竞争意味着位置之间的迅速移动。这就要求将原动机与钻机部件装在一起和将钻机设备分开以加速处理。
At present , most of the domestic simulation systems designed with analogy circuits , are easy to run out and affected by the ambient temperature with their complex structure and poor ability to withstand disturb 目前，国内现有的原动机仿真系统，大多采用模拟电路，存在结构复杂、电子元器件容易老化、易受环境温度影响、抗干扰能力差等缺点。
Repair and maintenance of motor vehicles as defined in section 2 of the road traffic ordinance ( cap . 374 ) but excluding prime movers trailers , tractors , chassis , container vehicles and container vehicles with trailers attached thereto 修理和保养《道路交通条例》 （第374章）第2条所界定的汽车，但不包括原动机拖架、拖头、底盘、货柜车及连拖架的货柜车；
By using the hydraulic torque converter to drive the mud pump , both the prime motor and the working machine can be protected , and the pump pressure can be controlled in the whole course of drilling if the rated rotary speed of the diesel engines is kept 通过液力变矩器驱动钻井泵可同时保护原动机和工作机；在保持柴油机额定转速的条件下，可实现泵压的全过程控制。
As is known to all , variable speed and constant frequency ( vscf ) system is a better solution for wind power generation than constant speed and constant frequency ( cscf ) system due to its higher efficiency to draw energy from wind 我们构建的这套系统可以看作由“上位机” (监控中心) 、原动机子系统(提供类似风车机械特性的机械转矩驱动)和发电机子系统(作为研究对象)三部分构成。
The power of the diesel engine is transmitted to the rudder propeller through an elastic coupling , a clutch and the universal shafts , the rudder propeller transmits the engine power to the propeller via upper and lower bevel gear sets ( z - drive ) 原动机（柴油机）的推进动力通常是通过高弹性联轴器、离合器、万向传动轴送到舵桨，舵桨将动力通过上、下两对螺旋锥齿轮付传送到螺旋桨，从而产生推力（ z型推进） 。
A ship ' s power station is a plant which generators and continuously supplies electric power to various auxiliary machinery on board and meets the electric power demands of the whole ship . normally , a ship ' s power station consists of a prime mover , generators and their ancillary equipment ( to form generators sets ) and distribution boards , being an essential part of the power system on board a ship 船舶电站是产生并连续供给辅助机械及全船所需电能的设备，它由原动机、发电机和附属设备(组合成发电机组)及配电板组成，是船舶电力系统的核心部分。
