木材中水分的含量,能影响它的重量;尤以新伐材含水量的多少,直接影响到木材运输和木材干燥方面实际应用的问题;因此我们过去在云南省和海南岛等林区采集木材试材和木材标本时,就其重要树种的生材(新伐材)含水率及公定容重等进行测定,目的在于求出生材及气干材每立方米的重量,以提供木材采运(尤其是水运)或交通部门对新伐材或气干材在概算木材重量时的参考依据;便于及时采取措施,合理采用运输方式,适当安排运输计
The amount of water in the wood can affect its weight; in particular, the moisture content of the fresh cuttings has a direct impact on the practical application of wood transportation and wood drying; so we used to collect wood in such forest areas as Yunnan and Hainan Island Test Specimens and Wood Specimens When determining the moisture content of raw wood (virgin timber) and its nominal weight for its important tree species, the purpose is to find the weight per cubic meter of raw and air dried wood for the purpose of providing timber pick-up (especially Is water transport) or the traffic department on the new lumber or air-dried wood in the estimated weight of timber reference; facilitate the timely measures to adopt a reasonable mode of transport, transport arrangements for the appropriate
