铅室

In the old lead chamber processnitrogen dioxide (NO2) was used for the oxidation though in practice mixtures of nitrogen oxides were used.

早期的铅室法工艺中用二氧化氮来氧化二氧化硫，尽管在实际生产中用的是氮氧化物的混合物。

When the propellant was lead styphnate and nickel hydrazine nitrate , their properties of ignition and thrust were investigated under different chamber diameter and different proportion of themixed propellant.

研究了史蒂酚酸铅和硝酸肼镍在不同药室直径和药剂配比下的点火和推进性能，并且计算了推力器参数对推力性能的影响。

With this model,the temperature growth process and temperature distribution of unit wall of epoxy resin,7740# glass,microcrystal glass and silicon units filled with lead styphnate were obtained by numerical simulation.

根据燃烧传热原理，建立了阵列单元燃烧传热过程的一维有限差分模型，运用此模型对装填斯蒂酚酸铅的7740玻璃、环氧树脂、微晶玻璃和硅药室单元燃烧40~80 ms过程中室壁温度成长和温度分布进行了数值模拟。

Considerableworks are necessary–a special set of tools, an apparatus of platina,leaden chambers, unassailable by the acid, and in which the transformationis performed, etc.

有不少设备都是必需的，如：一套特殊的工具、白金的仪器、不怕酸类腐蚀的铅室——用来在里面进行化学变化——等等。

Technician of imitate fixed position is affirmatory to place shoot wild reach protection to organize limits to go up at face guard with earmark pen draw the outline of, film image is saved contrast with equipment test and verify at computer, fall in identical parameter by technician to remedial computer room again, the position is blocked to undertake draw the outline of to lead with earmark pen on bracket of plumbic link stopper, send expanded plastics of patternmaking room cut, mould plumbic piece, refrigeration next shape, sticky finally stick plumbic piece to send imitate test and verify of fixed position room.

模拟定位技术员对所确定的射野及保护组织范围用记号笔勾画于面罩上，拍摄图像保存于电脑以备验证对比，再到治疗机房由技术员在相同的参数下，在铅挡块托架上用记号笔对铅挡位置进行勾画，然后送到制模室切割泡沫塑料、浇铸铅块、冷却成型，最后黏贴铅块送模拟定位室验证。2结果铅块制作。。。

It is prepared by the steps: using vacuum machine set to vacuumize the reaction chamber, then charging protective gas to generate electric arc between moving electrode and metal Pb, and quickly condenses Pb steam to deposit Pb powder in powder collector.

本发明所述的铅粉按以下步骤制得，用真空机组对反应室抽真空，再充入保护气体，在运动电极与金属铅之间产生电弧，对铅蒸气快速冷凝，沉降至收粉器中。

The combination of these two contrivances achieved recycle of nitrogen oxides and made lead chamber process become mature.

这两项发明的结合，实现了氧氮化物的循环使用，使铅室法制酸工艺基本成熟起来

Before the wide spread adoption of contact process, the chamber process was used.

在接触法普遍采用之前，使用铅室法。

Lead chamber process was improved continually in development henceforth.

此后，铅室法在发展中不断得到完善。

Six years later, John Roebuck in England adapted principium of nitroso process to build up a 6ft (1.89m) square lead-line chamber and carried out nitroso process reaction inside.

经过6年后，按亚硝基法原理，英国人丁·罗巴克在伯明翰建成一座6ft(1.89m)见方的铅室，在铅室内进行上述亚硝基制酸反应，成为世界上最早的铅室法制酸工厂。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
