Energy conservation and environment protection of cupola are important problem pressing for solution in current cupola melting.

冲天炉的节能与环保是密切相关的，是当前冲天炉熔炼中影响质量、效益和环境保护的急待解决的重要问题。

The cupola is a min kind of melting equipment.

冲天炉是熔炼铸铁件的主要设备。

Cupola is the most inportant melting equipment for production cast iron up to now.

冲天炉至今仍是铸铁生产最主要的熔炼设备。

In this paper,we research the influence of the ratio of Si/C on iron s strength,elasticity modulus and hardness in cupola s melting.

在冲天炉熔炼条件下，研究了SI/C值对灰铸铁抗拉强度，弹性模量和硬度等铸铁质量的影响。

In this paper,adaptive control approach of cupola based on neural network is brought forward and neural network as identification and controller is used to implement the self-adaption control of temperature of cupola molten iron.

提出了一种基于神经网络的冲天炉自适应控制方法，利用神经网络作为辨识器和控制器，实现对冲天炉熔炼过程中铁液温度的自适应控制。

In this study, copper alloy adding Ti-Zr and Al-Zr was the target and made the cupper alloy ingots by vacuum arc remelter. After rolling and heat treatment, the two-inch round target was cut by wire electrical discharge machining. DC sputtering deposited cupper alloy thin films on silicon base materials and optical glasses to discuss the thin film microstructures、compositions、practical performances and optical characteristics.

中文摘要本研究以自行设计之铜基合金靶材，在铜基材料中添加钛锆与铝锆等微量金属，以真空电弧熔炼制作铜合金方锭，经滚压加工及热处理后，以线切割机切成两吋之圆型靶材，再进行直流溅镀沉积铜合金薄膜於矽基板和光学玻璃基板上，探讨不同成分比例下之薄膜显微结构、成分组织、实用性能与光学特性。

Many other European smelters could close because they are unable to strike cut-price new deals for electricity as older contracts run out.

许多其他欧洲熔炼厂则可能由于旧的供电合约结束后无法缔结新的廉价电力合约而关闭。

The four conditions are as follows: the molten alloy only with the addition of deoxidant during melting; only applying high-density pulse electric current on castings during solidification; compound addition of grain refiner and sodium modifier, and addition of borax r modifier liquid along with applying pulse electric current during melting.

这4种工艺条件分别为：在合金液熔炼过程中，除了加脱氧剂外不做任何处理；凝固过程中单独施加高密度电脉冲；添加晶粒细化剂和钠盐变质剂混合剂，或者添加硼砂变质细化剂，并施加高密度电脉冲。

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
