Advanced technique in world in world in now in Euro-American region in adoption in product.

产品采用欧美地区当今世界先进技术，该机选用进口的变频控制技术，在机器驱动速度调整时能够随意控制电机的转速快慢或在机器运转时能任意无级变速，目前该产品远销美国、日本等国家和地区。

This study investigated the neutron contaminations from medical accelerators, including electron linear accelerators and proton cyclotrons. The evaluation methods and data for neutron shielding were also provided for practical uses.

本论文探讨医用加速器－包含电子直线加速器与质子回旋加速器，在运转过程中可能发生的中子污染，并建立辐射屏蔽的评估模式与数据资料。

The function of the control system is starting and controling motors,checking and measuring the number of the black lines,measuring the distance and motor speed,calculating the time,and displaying any required digitals,etc.

主控制系统的功能主要是启动并协调电机运转，测量行程转速，计算行驶时间，实时显示所需的各种参数等。

The solar system is part of one of such self generating cosmic exertions.

太阳系是这些自发的宇宙运转活动中的一部分。

AC Induction Motor Control Using the constant V/f Principle and a Natural PWM Algorithm (12 pages, revision A, updated 12/05) Induction motors can only run at their rated speed when they are connected to the main power supply. This is the reason why variable frequency drives are needed to vary the rotor speed of an induction motor.

使用V/F原理的交流电机控制和简单的PWM算法（12页，修订版A，更新时间：05年12月）交流电机在连接到电源时只能以其额定速度运转，所以要改变转速必须改变电源频率。

The pulley or fan bore shall be concentric and match the diameter of the rotor shaft.

风叶和皮轮必须无磨损或损坏，皮轮不应有碎屑，弯曲或其它瑕疵会干预驱动器皮轮的正常运转，皮轮和风叶孔应同心并与转子轴的直径相匹配。

With the reform-opening and the gradual establishment of socialist market economy system, large quantities of fanners flooded into cities, including a number of key population, which made those cities more and more complex.

人口管理是公安工作的基础，加强人口管理是关系到社会生活正常运转，关系到改革开放和社会主义市场经济建设，关系到政治稳定和社会稳定的大问题。

We have received your letter of …, regarding the faulty operation of the newly delivered PF Freezers.

贵方关于新近交货的冷冻机运转不灵一事的来函收到了。

Their operation must be synchronized with the operations of the existing furnaces.

这种操作必须同现有的高炉设备的运转同时进行。

A front-back seal ring structure is adopted in the pump to prevent the liquid from leaking from the high-pressure area to the low-pressure area. The front seal ring is mounted on the pump body while the back seal ring mounted on the bearing body. They should be changed when they are so worn-out that they have an effect on the efficiency and self-priming performance of the pump after the operation for a long time.

泵内部防止液体由高压区向低压区泄漏的密封机构是前后密封环，前密封环装在泵体上，后密封环装在轴承体上，当泵经长期运转密封环磨损到一定程度，并影响到泵的效率和自吸性能时，应给予更换。

She gently rebuff ed him, but agreed that they could be friends
