The radiation mainly happens on the glass surface, and the transmission on the window frames and glass. The air leakage is mostly owing to the improper window structure or bad sealing.
同时， 不同的火焰循环时间和空气渗漏对焙烧的能耗影响较大， 降低火焰循环时间将导致能耗增加， 而降低空气渗漏量则可极大地降低能耗。
It is also found that the fuel consumption increases with the decrease of firing cycle time, and cutting down the air infiltration will be helpful for saving fuel.
间歇泉似的喷柱不断喷发，泥浆翻腾着，而且蒸汽从峭壁和人行道上渐渐地渗漏出来，空气中留下了硫磺气味。
