This company explores new-style and compound corrosion inhibiter and block dirty agent actively still to apply mediumly in water of turbine condenser loop, below the premise that makes sure equipment safety moves, make circular water utilization rate rose 3 to 5 times, raised the utilization rate of water natural resources.

该公司还积极探索新型复合缓蚀剂和阻垢剂在汽轮机冷凝器循环水中的应用，在保证设备平安运行的前提下，使循环水利用率提高了3至5倍，提高了水资源的利用率。

It used air/water mixture as refrigerant so as to be absolutely environmentally friendly.

水的相变改善了空气的压缩和膨胀过程，同时又增加了制冷量，使循环具有很高的经济性。

The invention relates to a processing method of preventing frostbite and restarting of hydrogen electric pile, whose characteristic lies in the treating processes includes: When the electric pile turns off, the unsaturated fuel gas or the nitrogen, through the circle boast to clean the dissociate water; drying the MEA film module to keep the water content below the stipulated temperature which does not ice up; then the recycle gas through a wet exchanger to dry and the dried gas is continue used in the dry pile step; when restarting the electric pile, the recycle gas must heats then through the pile to elevate the temperature, then heats the fuel gas and the oxidant of the gas source, through the weting of the wet exchanger enters to the calefactive pile, enhances the wet step of the film module in the pile, starts the power output of the pile.

本发明涉及一种氢电堆的防冻和重新启动时的处理方法，其特征在于处理过程包括：电堆停机时，将水蒸气不饱和的燃料气体或氮气，通过循环吹扫除去电堆的游离水；干燥其中的MEA膜组件，使膜组件含水量降低到规定低温下不结冰的程度；而后再令循环气体通过一个湿交换机将循环气体干燥，以及被干燥后的循环气体继续用来干燥电堆的步骤；在电堆重新启动时，须将循环气体加热后通过电堆，使电堆升温，然后再将气源的燃料气及氧化剂加热，通过湿交换机加湿后进入已升温的电堆，提高电堆中膜组件的湿度的步骤，开始电堆的功率输出。

This places the loops and loose ends further away from the bicycle chain, cranks and other moving parts.

这使循环和松散的两端进一步远离自行车链条，曲柄和其他运动部件。

Array privatization is one of the most effective loop transformations for the exploitation of parallelism. This transformation technique privatizes arrays according to the information of the data dependence analysis, which eliminates the memory-related dependences, i.e. anti and output dependences, to make the loop execute parallel.

数组私有化是开发并行性最有效的循环变换技术之一，它以数据依赖关系分析为依据对数组进行私有化，消除循环中的存储关联数据相关，即反相关和输出相关，使循环可以并行执行。

To cycle the action when the oil drain back into the worm gear in the box, separate the return of the oil storage tanks, resulting in increasing number of worm gear box of oil, while the oil inside the oil less and less.

经检查与分析，发现是因蜗轮、蜗杆的密封圈磨损、密封不良，使循环动作的机油在回流时漏入蜗轮箱内，分流了返回储油箱的机油，造成蜗轮箱内的机油越来越多，而储油箱内的机油越来越少。

It is clarified for the first time that the thermal fatigue failure of solder joint is actually a creep strain low cycle fatigue failure, and a physical model for creep fatigue crack propagation has been proposed. It was pointed out that creep strain increases in the high stress area ahead of the tip of thermal fatigue crack, results on one hand that the slide of crack tip increase, inactivation more serious and crack close length increases, the other hand, that intergranular crack exists, whose direction will affect the fatigue crack propagating.

本文首次阐明了焊点的热循环失效本质上是以焊点内循环蠕变为主要应变的低周疲劳失效，并在此基础上提出了蠕变疲劳裂纹扩展的物理模型，指出热循环裂纹前端的高应力区内，蠕变加剧，使裂纹前端滑移增加，裂纹钝化加剧，导致随后的裂纹闭合扩展长度增加；同时蠕变也使裂纹前端的高应力区出现晶间裂纹，蠕变沿晶裂纹对主裂纹扩展的影响取决于沿晶裂纹的连接方向。

To close the headpin, making a loop with round nosed pliers and then twisting the wire around the loop will make a more professional and secure closing than just making a loop.

若要关闭headpin，使循环圆鼻钳，然后扭曲的电线周围的循环会更专业和安全的关闭比只有一个循环。

Bucher diagram is that the carnot cycle characteristics, a simple and practical m-xt Bucher diagram paper, the start of the carnot cycle is used to express the prototype, after the further improvement and to promote its application in various thermodynamic cycle as Rudolf circulation, three heat cycle, reverse circulation within a brief reversible, makes people aware of the limits using Bucher diagram, the rich contents.

Bucher图是表示卡诺循环特性的一种简单而又实用的新图，本文对Bucher图的最开始的用于表示卡诺循环的原型，之后对其进一步的改进和推广使其应用于各种热力学循环如狄塞尔循环，三热源循环，逆向内可逆循环等作了简要的叙述，使得人们了解到Bucher图的使用范围的广泛，内容的丰富。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
