        摘要：In this article,2 formulations(F 1 ,F 2 )of chlorothalonil as anti mold agents were developed and applied to two wood testing species,e.g.Populus canadensis and Pinus massoniana.The testing results showed that chlorothalonil formulation F 2 was equivalent to or even better than sodium pentachlorophenol (NaPCP) in against mold fungi Penicillium citrinumand Aspergillus niger in laboratory test.

        摘要：This paper discussed lengthwise scarf jointing technique for veneers peeled from several domestic wood species commonly used for making plywood.Experimental results showed that the veneers 1 mm thick or thicker could be lengthwise scarf jointed.Suitable slope of the scarf jointing was 3°～5°. Scarf joints had little effect on mechanical and physical properties of plywood made from the veneer.The scarf jointed veneers were good for making plywood used for concrete formworks,structure and surface finishing.The jointed veneer was suitable for conventional plywood production.

        摘要：The paper discussed three aspects of platen drying sliced veneers from small diameter logs of two species( Betula platyphylla,Quercus mongolica ):(1)the influence of platen drying upon the warp of the veneers;(2)the relation between platen drying parameters(include their interactions)and final MC as well as thickness losses of the experimental materials,and a regression equations were established;(3)the platen drying parameters of the veneers were optimized according to testing microcosmic structure of the veneers via scanning electron microscope.

        摘要：It was determined that discoloration of paulownia wood resulted from fungi except other reasons. Two fungi, Alternaria alternata and Rhizopus sp.,were identified from green paulownia wood, which apparently trigger black brown discoloration of paulownia wood.

        摘要：Polycarboxylic acids acts as esterification agents and inorganic salts acts as catalyst in wood crosslinking reaction.A new water soluble non formaldehyde crosslinking system was composed of these two chemicals with characteristics of poison free and pollution free.This paper discussed permanent fixation of heavy compression deformation of wood by using the system.Recovery of Populus ussuriensis wood treated with 1,2,3,4 butanetetracarboxylic acid (BTCA) with 9% concentration was very low in dry condition.Recovery was nearly 27.01% by immersion in boiling water.The specimen were permanently fixed with the system by suitable concentration,e.g.9%.Surface color of the specimen slightly varied from red to yellow.

        摘要：By comparing testing results of drying lumber from fast growing plantation species with and without surface pressuring,the authors proved that different surface pressure affected wood drying warp distortion.But a phenomenon existed that surface pressure of 9 800～10 780 N (1 000～1 100 kgf/m 2) was effective on restraining wood drying warp distortion for thin lumber of populus tomentosa,Pinus taeda and Larix olgensis, and ineffective for thin timber of Robinia pseudoacacia,Pinus massoniana,Pinus elliottii and Larix kaempferi.The reason should be studied further.
