乙炔

Nickel was even harder; he cheated and bought some commemorative coins, melting them with an oxyacetylene torch.

镍更难获得；他以哄骗加购买的方式，得到了几枚纪念币，用一支氧乙炔焊炬把它们熔化。

Perfect.You and sheldon go to the junkyard and pick up 6 square meters of scrap aluminum?Raj and i will get the oxyacetylene torch.

Howard完美，你和谢尔顿去废物堆积场找个6平方的铝合板，我和拉杰搞定氧乙炔喷焊器。

An extremely hot flame can be produced from an oxyacetylene torch. For certain welds an electric arc is used.

氧乙炔焊炬可能会产生极其热的火焰，对于某些焊缝来说可能会用到电弧，在此方法中，电流通过两个电极，并且金属表面被置于两电极之间。

The composites all retained structural integrity after 30 seconds ablation in an oxyacetylene torch, but flexural strength decreased to 121.16MPa to 140.23MPa to 122.87MPa, and the corresponding mass ablations were 0.036g/s, 0.050g/s and

三种复合材料试样在氧乙炔焰烧蚀30s后，试样结构均保持完整，弯曲强度分别下降到121.16MPa、140.23MPa、122.87MPa，质量烧蚀率分别为0.036g/s、0.050g/s、

The preferred method is by oxyacetylene flame.

首选加热方法是采用氧乙炔火焰。

Mainly in oxyacetylene cutting installed in the gun fire.

主要是在进行氧—乙炔火焰切割时安装在火焰枪上。

If oxyacetylene flame or plasma is adopted, surface coat that can impact welding quality shall be removed after cutting.

当采用氧乙炔焰或等离子切割时，切割后必须除去影响焊接质量的表面层。

The experiment of testing the moving oxyacetylene flame shows that this sensor can be used to measure the transient high temperature up to 2000℃.

运动乙炔焰模拟测试结果表明，高温测试范围可达2000℃，可用来对兵器及国防工业等诸多涉及燃烧和爆炸等过程的瞬态温度进行测试。

6 Oxyacetylene flame can' be used for welding of pipeline.

7.1.6 管道焊接不得使用氧乙炔焰焊接。

The microstructure of the coating and the mechanism of the wear resistance were analyzed. Compared with the coating using oxyacetylene flame process, results showed that the wear resistance of coating prepared by plasma spray welding process is higher than that of the coating using oxyacetylene flame process.

进而对涂层的微观组织和耐磨机理进行了分析和研究，并且与氧乙炔火焰喷焊技术所制备的涂层进行了对比测试分析，结果表明，利用等离子喷焊技术所制备的超厚涂层耐磨性能更为出色。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
