过热的

A large proportion of tube bursting is caused by flow rate deviation induced by incorrect configuration of superheater and reheater system.

其中过热器、再热器采用的不合理结构，如弯头、三通等引起的并联管组上的流量偏差导致爆管占了较大比重。

The effects on superheated vapor heat transfer are to be analyzed such as heat flux and mass flow rate etc.

实验结果表明，在外部条件相同时，环形狭缝通道内的过热蒸汽的换热系数随着间隙的减小而增大。

The model can be used for distributed superheater thermal calculation, and can provide a base to develop a dynamic distributed parameter model of superheater system.

该模型可以用于过热系统的分布式热力计算，并可为过热系统分布参数动态模型的建立提供必要的边界条件。

Experimental research on effects of a uniform electric field on plate pool boiling heat transfer enhancement was carried out. It's found that in the scope of lower overheat, boiling heat transfer is significantly enhanced under electric field.

对均匀高压电场作用下平板池沸腾换热的强化效果进行了试验研究，发现在较低过热度的范围内电场对换热有明显的强化效果。

The results show that the toughness of over-heated zone increased greatly because of austenite film lying in lathy martensite and a few ferrite.The toughness of fine grained zone decreased due to many factors,such as acicular martensite,a small quantity of austenite film,carbide separation and so on.

结果表明，10Ni8CrMoV这一新型钢种的模拟焊接热影响区的过热区和细晶区表现出与绝大多数材料完全相反的规律，过热区存在少量的铁素体组织，马氏体板条束之间形成了一定量的奥氏体薄膜，这些韧度相的存在使得过热区的冲击韧度与基体相比有了较大的提高；细晶区部位奥氏体含量很少，细小的板条马氏体端部呈针状特征造成应力集中，易于诱发裂纹。

There isn' t overmany differences in the materials, structure, and manufacturing procedure of economizers, superheaters, reheaters and headers between 900MW supercritical pressure monotube boiler and the former boilers made in our company, except the size is bigger.

90 0MW超临界直流锅炉与上海锅炉厂有限公司以往制造的锅炉产品相比，其省煤器、过热器、再热器及相应集箱的材料、结构和制造工艺除了尺寸较大之外无大的差异。

The area of steel ring of the assembly sample was enlarged thus to keep the temperature field even and to protect the anvils from excessive heating. The pause pressure was chosen to be 90% that of synthesizing pressure; the pause duration to be 500~600 s. Our newly developed linear no-power depressurization technique was used for uniform depressurization. The synthesizing duration was selected to be 40~50 min, and the stop-heating time was delayed by 20 s.

在组装方面，增加了导电钢圈的导电和导热面，以均衡温度场并防止顶锤表面过热；采用合成压力的90%作为暂停压力；暂停时间选为500~600s；采用最新实验成功的线型无动力卸压方式匀速卸压；合成时间取40~50min；延缓停热时间20s。

For different configuration of the distributor,the flows of R134a outside the horizontal tube under different working conditions were simulated and calculated.

降膜式蒸发器是利用制冷剂管外蒸发达到与管内工质换热的目的，即冷媒介质在蒸发管内流动，与蒸发管外流过的制冷剂液体进行换热，使其蒸发，实现热量的传递。

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.

也许他们将在壶穴里消失
