        摘要：Features of the strains in some southern hardwoods during the first drying stagewere studied under various temperature and equilibrium moisture content.The results shownthat surface layer represented tensile elastic strain and plastic strain , while internal layerrepresented compress strain. The maximum tensile elastic strain was the main factor whichresulted in surface-checking,and the set caused by plastic strain was the reason of inner-checking.The elastic and plastic strain were greatly influenced by the equilibrium moisturecontent and interrelated with the MC gradient.Drying time during the first drying stage bedetermined by the ratio of the MC when the surface reached the maximum tensile strain andthe initial MC.

        摘要：In order to improve the performance of particleboard made from mixture of reed and flax stalk,the relevant technology issues,including the modification of adhesive,the sur- face treatment of reeds, the optimal manufacturing technology,were studies,which resulted in the establishment of the optimal manufacturing technology and the working plan for trial production。The results of the trial production indicated that the physical and mechanical properties of the board could meet the requirement of the National Particleboard Standard(GB/T 4897─92).The production cost is lower than that made from other raw materials in our country。By means of properly innovating the production line of particleboard of flax stalk,qualified particleboard from reed and flax stalk can be made。 This new technology makes it possible to use a new kind of raw materials in flax stalk particleboard factories which are facing the shortage of raw material supply。It will also widen the way of the utiliza- tion of reed。

        摘要：The NEM-2 digital moisture meter is designed for particleboard production lines. The changes of electric capacity produced by moisture content difference of wood particleswas measured by means of frequency method,which could be used for determination of mois-ture content.The meter is controlled by MCS-51 single chip computer.
