When hydroturbine generator runs in steady state,oil film stiffness and dampingcan greatly affect the unit s vertical vibration.

水轮发电机稳态运行时，油膜刚度与阻尼对机组的垂直振动有着重要影响。

In the chapter 7, a new type of highly reliable and multifunctional hydroturbine microcomputer-based governing system is studied and developed; the structure design principle of microcomputer-based system is described and discussed; based on the adaptive control strategy with optimized PID parameter, a combined control strategy of frequency and phase with variable weighting factor is presented; in the design of hardware and software, the fault diagnosis, fault tolerance and fault avoidance techniques are adopted, and the suitability and reliability are greatly improved.

第七章研究开发了一种新型的高可靠多功能水轮机微机调节系统，论述了微机系统的结构设计原理，在适应式PID参数优化调节控制策略的基础上，提出了机组空载运行时的变权系数频率和相位综合控制策略；在微机调节控制器的硬软件设计中，全面应用了故障诊断技术、容错处理和避错处理技术，大大提高了整个系统的适应能力和可靠性。

So the study of on-line monitoring system and test technology on large- scale hydropower units is very impendency and important.

所以，在大型水电厂和大机组开展主设备在线监测技术的研究是十分迫切而又极为重要。

So the study of faults diagnose system and test technology of large- scale hydropower units is very impendency and important.

而对机组进行故障诊断，改传统的计划周期性检修为计划性检修与状态检修相结合，就可大大降低生产成本，从而提高电厂的竞争能力。

Conference, UV printing for impregn innovativeink could not obtain the business card printing and membership card making effect, is UV ink is available at the moment is not under UV curing, so business card printing and membership card making, hot stamping, die-cutting and other membership card after processing can be completed online line, thereby significantly shortened production speed, especially suitable for unit type flexo printing machine.

在刚印洋，UV印品之所以能得回用其他油不朱无法得回的制卡和会员卡制息成果，不离在于UV油不朱可在紫边不照射下长期固化，因此制卡和会员卡制息，烫印，模切及其他会员卡制息后增工等都可以在一条不出产线上联机达成，从而不小不小放缓了不出产速率，不出格不合用于机组式刚印机。

Therefore, the bidding prices of generators and the line capacities are introduced into the TNUoS charges. Furthermore, the indiscriminatively summing up of the costs of all lines is replaced by mainly summing up the costs of congested lines.

因此，在电网使用费的计算中引入了机组的报价和线路的传输容量，而且体现出阻塞线路和非阻塞线路的差别。

This thesis proposes the optimization scheme of the 50MW coal-firedutility boiler in order to save Energy, decrease capital cost and operation cost, and realize thereuse, decrease and innoxious disposal of the waste, through the analysis of Flue GasDesulphurization System with Ammonia from home and abroad.

本文通过对国内外氨法脱硫工艺系统的分析，提出了某电厂50MW燃煤机组氨法脱硫设计的优化方案，达到节能降耗、降低投资及运行成本的目的，实现废弃物资源化、减量化和无害化。

With isentropic ranges of efficiencies of up to 92%, our compressors achieve top results in international comparison!

在等熵条件下，我们机组的效率可以达到 92%，处于世界同类产品的领先水平！

This unit picks the waterused achievement to carry the freezing mixture, also allows to use theglycol or the sodium chloride, the calcium chloride isohydric solutionachievement carries the freezing mixture, but when uses the sodiumchloride, the calcium chloride should select the antiseptic to protectthe copper pipe

本机组采用水作为载冷剂，也允许采用乙二醇或氯化钠、氯化钙等水溶液作为载冷剂，但当采用氯化钠、氯化钙时应选用防腐剂以保护铜管。

The plane, which was found loaded with about 35 tons of weapons including missiles and rocket-propelled grenades, was impounded Saturday as it landed to refuel at Bangkok's Don Juang Airport. The 5 crew members, including one from Belarus and the rest from Kazakhstan, were detained for further questioning.

据了解，这架来自朝鲜的飞机12日在曼谷廊曼国际机场降落加油时被扣押，原因是其载有35吨各类重型武器，其中包括导弹和火箭弹。5名机组人员中目前正在接受审讯，其中一人为白俄罗斯籍，另4人为哈萨克籍。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
