生材含水率(指绝对含水率),系指新伐材中水分的重量与木材绝干重量之比的百分率。各树种生材含水率的数值,在木材加工企业设计、成材及单板干燥、以及交通运输上是—个主要的参考依据,具有重要的实际意义。 我国重要树种生材含水率的测定,近年来已为研究单位及高等学校所注意,并已进行了很多工作,提出了一定的数据([1],[2][3]等),但多偏重于南方树种(安徽、云南、海南岛等),涉及东北树种较少。
Raw material moisture content (referring to the absolute moisture content), refers to the proportion of moisture content of fresh cut wood and wood absolute dry weight ratio. The value of moisture content of each tree species in wood processing enterprises design, timber and veneer drying, and transportation is - a major reference, with important practical significance. In recent years, the determination of the moisture content of the important tree species in China has been paid attention to by research institutes and institutions of higher learning. Much work has been done and some data ([1], [2], [3], etc.) Emphasis on the southern species (Anhui, Yunnan, Hainan Island, etc.), involving less species in the Northeast.
