英文: It is expected that the dimension of cubicle type GIS can be further reduced if the SF/air (90/0)gas mixture is used.中文: 因此在气体绝缘开关柜中采用混合比为90/0的SF_/空气混合气体,可望使开关柜尺寸进一步缩小。英文: Air is a mixture of gases.中文: 空气是气体的混合物。
Significant correlations were demonstrated between injuries and age, work experience, physical condition, impaired vision, difficulty in breathing due to smoke and toxic gases, sudden weight lifting, inadequate technique and lack of personnel and equipment (p<0.05). CONCLUSIONS It is apparent that the...
•Class C fires :Fires involving flammable gases, such as butane and methane Dry Powder extinguishers put out fire by coating the fuel with a thin layer of dust, separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire...

If this was to happen, your cute Cornish cottage would likely be at risk of subsidence or other types of significant damage. Having a historic mine nearby can also have environmental implications. It’s possible for explosive gases to build up in abandoned shafts and tunnels, and any water ...
Inorganic semiconductors typically have limited p-type behavior due to the scarcity of holes and the localized valence band maximum, hindering the progress of complementary devices and circuits. In this work, we propose an inorganic blending strategy to
Electronic nose applications in environmental monitoring are nowadays of great interest, because of the instruments' proven capability of recognizing and discriminating between a variety of different gases and odors using just a small nu... Capelli,Laura,Sironi,... 被引量: 55发表: 2014年 加载更多...
