运行时间

After aqueduct bridge is built, all kinds of reasons get its degree of safety descent so as to affect its ordinary run with the time going.

渡槽建成运行后，随着时间的推移，由于种种原因会使渡槽的安全度有所下降，以致影响其正常运行。

When the train running continuously, the temperature of axles and the axle's bearing will rise. This will induce some accidents about the train. It is a great hidden trouble when the train running.

列车长时间的运行会使列车轴承和车轴温度升高，有可能导致切轴甚至列车颠覆，是列车运行中的重大隐患。

No brush No ring starter remove the traditional 、complicated、multiconduction component starting equipment. it is easy to operate and install, less repairing expense. the advantage is: to keep the original operation without rings、carbon brush、brush box、brush box shell、short circuit ring and ajustable rheostat frequency sensitive rheostat on secondary loop system AC connector and time relay.

无刷无环起动器把传统的、繁琐的、多触点元件组成的起动装置去掉，采用无刷无环运行，操作简单，安装拆卸方便，可大大减少维修费用，其优点是：去掉滑环、碳刷、刷盒、刷盒支架、短路环及二次回路系统中的频敏变阻器、交流接触器、时间继电器等元件，并可保持电机原有的运行特性。

Rated at extraction conditions, one pump is running, because the cycle of water to reduce the system's water resistance decrease the flow of water pumps 12274T / H, head will drop to 15.0-16.0 m, in the extraction steam turbine at the maximum operating conditions, the recycled water to meet the system requirements to run a pump, because of substantial reduction in the volume of water supplied, so that substantially improve pump head, a direct result of the cooling tower water gushing, increase淋水device with a flow rate of the sink, fill up water in the hot淋水exchange reduce the time and reduces the cooling effect of cooling towers.

在额定抽汽工况下，一台水泵运行，由于循环水量减少、系统的水阻下降，水泵的流量12274T/H，扬程将下降至15.0-16.0米，在汽轮机在最大抽汽工况时，为满足循环水系统要求运行一台水泵，由于供水量大幅度减少，使水泵扬程大幅度提高，直接造成冷却塔涌水，加大淋水装置配水槽的流速，水流在淋水填料上热交换的时间减少，降低了冷却塔的冷却效果。

After gravity dehydration, the sludge almost losses its mobility. With the filter belt press forward, the space between gradually reduced, the material began to receive a slight increasing pressure. Wedge-shaped area's role is to extend the gravity dehydration time, increase the stability of the floccules, to prepare for entry into the pressure zone.

重力脱水后的污泥流动性几乎完全丧失，随着带式压滤机滤带的向前运行，上下滤带间距逐渐减少，物料开始受到轻微压力，并随着滤带运行，压力逐渐增大，楔形区的作用是延长重力脱水时间，增加絮团的挤压稳定性，为进入压力区做准备。

Electric motors keep the trains level as they travel the four-minute trip up or down the arch.

电力发动机使火车保持平衡运行，向上或向下需要运行四分钟的时间。

It is now well established that system outages are caused more due to software faults than due to hardware faults. Software aging is a kind of software fault which is a phenomenon that the state of the software system degrades or crashes with time. This phenomenon exists in all kinds of applications that run a log time.

软件故障所引起的系统运转中断远远高于硬件故障，而软件老化是软件故障的一种，它是指软件运行一段时间之后性能下降甚至崩溃的现象，这种现象广泛存在于各种长期运行的软件之中。

In this theme, it is resolved the problem that how to monitor the running status of the semiautomatic grab unloaders The system can discover and forecast the failure in time, avoid the magnitude accidents and enormous economic loss, what is more, we can dig out the hidden troubles from the running status of the equipments and cut down the failure stop time caused by human being.

文章解决了对半自动桥式抓斗卸船机运行状况的监测问题，可以及时发现、预告故障，避免重大事故的发生和巨大的经济损失，而且可以根据卸船机的运行状态找出生产系统中的事故隐患，消除事故隐患，减少由于人为和技术因素引起的故障停机时间。

The robot is controlled through a ruggedized laptop with a game-style controller, operates at speeds of up to 5.8 miles per hour and provides up to four hours of mission run time.

该机器人通过内置游戏式控制器的加固笔记本电脑来控制，运行时时速高达5.8的速度，并提供多达4个小时的时间运行任务。

As the temperature condition for operation of cooling tower was lower than the design wet-bulb temperature most of the time,it was uneconomical to use single-speed motor,and the use of inverter-fed motor also cost higher.

冷却塔运行的气温条件大部分时间低于设计湿球温度，采用单速电机运行不经济，采用变频电机设备费用较高，为解决这些问题，开发了适合冷却塔应用的变扭矩变极电机。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
