标题:辐射通量, 临界辐射通量
正文:
辐射通量(kw/m2) heat flux (kw/m2)单位面积的入射热,包括辐射热通量和对流热通量。Heat flux(kw/m2) heat flux (kw/m2)Amount of thermal energy emitted, transmitted or received per unit area and unit time.熄灭时的临界辐射通量(CHF) critical heat flux at extinguishment (CHF)样品表面火焰停止传播并熄灭的位置所对应的辐射通量(kw/m2)。critical heat flux at extinguishment (CHF)Incident heat flux, in kw/m2, at the surface of a specimen at the point where the flame ceases to advance and may subsequently go out.X分钟的辐射通量(HF-X) heat flux at X min (HF-X)试验开始x分外时，样品上火焰传播最远距离处抽对应的辐射通量(kw/m2)。heat flux at X min (HF-X) heat flux, in kw/m2, received by the specimen at the most distant spread of flame position observed during the first X min of the test.临界辐射通量 critical heat flux 火焰熄灭处的辐射通量(CHF)或试验30min时火焰传播到的最远位置处对应的辐射通量(HF-30)，两者中的最低值（即火焰30min内传播的最远距离处所对应的辐射通量）。critical heat flux heat flux at which the flame extinguishes(CHF) or the heat flux after the test period of 30min(HF-30),whichever is the lower value(i.e. the flux corresponding to the futhest extent of spread of
