气焊

At present, Hengjin has produced more than 600 sets of high vacuum agglomerating furnace, high pressure air quenching furnace, high vacuum brazing furnace, high vacuum annealing furnace, vacuum annealing equipment, vacuum nitriding equipment, vacuum crystallizer, vacuum fast quenching equipment, vacuum melting equipment, vacuum storing equipment, vacuum operation box, vacuum dryer, etc.

恒进真空已先后研制了高真空正压烧结炉；高真空高压气淬炉；高、低温真空钎焊炉；真空退火炉；真空速凝铸带炉；真空回火炉；真空晶化炉；真空破碎炉；真空储藏柜；真空操作箱；真空干燥器；真空保鲜室和真空镀膜机等真空设备，客户遍布全国二十多个省市，并远销到韩国、泰国、越南、朝鲜、伊朗等国家。

Welding to materials like aluminum, copper, white metal, and brass that have low melting temperatures and are easily oxidized, can be facilitated by flushing the welding spot with nitrogen, argon, helium, carbon dioxide or some similar protective gas.

焊接那些像铝、铜、白合金、黄铜这些熔点很低、易于氧化的材料，使用氮气、氩气、氦气、二氧化碳或一些类似的保护气体，吹洗焊接焊点。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
