        摘要：Considering the insufficient knowledge on plywood manufacture and related woodproperties of loblolly pine grown in China,wood density,hardness and MOE with grain per-pendicular to testing span were determined, and veneer peeling tests under various cuttingconditions were made,Based upon test results,relationship of wood properties to proper ve-neer peeling conditions and veneer qualities were analyzed. Wood properties proved to haveconsiderable effects on veneer qualities and proper cutting conditions. High quality veneer canbe obtained under proper peeling conditions.

        摘要：sND0-60”wood drying kiln charged with fork-lift was designed for wide span andlarge capacity.The kiln was constructed of masonry with a large hanging door.propellerfans,heating elements,advanced measuring and controlling devices were adopted.Since thekiln construction and dimension were reasonable and the equipments performed very well,theefficiency and energy-saving were improved remarkably. In addition,it was durable,easy tooperate and convenient to maintain.

        摘要：As people in the world are getting more and more aware that economic develop-ment must match up with natural resource consumption and environment protection,it is nec-essary for scientists to rethink systematically research and development of wood-based mate-rials with life cycle assessment(LCA)method and to make wood-based materials more envi-ronmentally friendly. Waste wood-based materials include waste solid wood,waste wood-based composites and waste paper. This paper discussed briefly the background,methods,re-search needs and benefits regarding to the utilization of waste solid wood and waste wood-based composites.

        摘要：Parallel Oriented Special Bamboo Strip Board(POSBSB)made of small diameterbamboo,such as Phyllostachys praecox and Phyllostachys prominens,with PF resin adhesivewere studied.Results showed:① With green covering-unremoved strip of bamboo,MOR ofthe POSBSB was more than 100 N/mm2 and MOE 1×104N/mm2 under normal conditions,②In order to obtain certain MOR of POSBSB after water treatment,PF resin impregnating con-tent of the strip should be kept at certain level.③The thickness expansion rate of water ab-sorbing was too high for further work to be done.
