In first, a new short time formula of one dimension heat conduction differential equation, based on the theory of one dimension transient method, is presented for thermophysical property measurement of wood. The result of testing on red pine and larch wood arc satisfied by new method.In succession, the relationship between heat conductivity of wood and moisture, density, porosity, temperature and grain is studied experimentally in the range from 25 to 100℃. The result shows that, the heat conductivity is in direct proportion to density. but in inverse proportion to porosity. The heat conductivity of air-dried wood increased probably linear with the temperature rising. And that heat conductivity along the grain of wood is higher than that cross the grain. The former is 1.8 or 2 times of the latter.

In the process of wood drying, because that the dry rate on the surface of wood is ten times than which inside, the moisture content of wood on the surface reduce to the fiber saturation point first, and begin to shrinkage, but the moisture inside content of wood is far higher than the fiber saturation point, the higher the standard criterion in wood drying, the more obvious of shrinkage.
