Wood is charred by exposure to thermal radiation, the depth of the char being closely proportional to the radiant exposure.
木料受到热辐射照射后就会烧焦,烧焦的深度大致上与辐射照射成正比。

It is significant for supplementing flame retarded wood theory to study the function of char forming and smoke suppression of zinc borate applied in wood flame retarding field systematically.
Experimental data showed that for the treated wood there was an increase in char yield and LOI, and decreases in activation energy and temperature of decomposition.
