| 摘 要： | 为了研究采用电场手段改良杉木的可行性,将一定含水率的杉木板材置于不同的电场强度(极板间电势差)中,并在杉木板材上部稳定地保持一定量的氯化钠溶液,5 h后,测试板材不同高度(厚度)部位的含水率和钠离子含量,并与未在电场中渗透的杉木的对应值比较分析,研究电场强度对氯化钠溶液在杉木中渗透能力的影响,结果表明:①定向电场的存在,能促进氯化钠溶液在杉木中的渗透;②在本试验范围内,随着电场强度的增加,氯化钠溶液中水分和钠离子在杉木中、下部渗透量增加,并使各渗透层面的含水率均匀性提高.

| Abstract: | Studies on improvement of Chinese fir by electric intensity were carried out for the effect of electric intensity on Chinese fir log osmosis of sodium chloride solution. The result showed that the existence of directional electric field could promote the osmosis, and along with the increase of electric intensity, water and Na ion increased of sodium chloride solution, and the eveness of moisture rate of each osmosis layer increased. |
