外文摘要：In order to overcome the above-mentioned negative effects， the fresh Chinese-fir shavings were extracted in KOH soltion， were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood。 The results are as follows: (1) The extraction mass arrived at the maximum value when KOH concentration is about 17。5%。 The micro/nano particles in Chinese-fir shavings would be discharged sufficiently in the KOH solution with the increaing of extracting time。(2) The diameter the micro/nano particles of wood extractives and hemicellulose is comparatively scattered according to volume fraction。 Micro/nano particles in the diameter of 91。3-342 nm， 91。3-342 nm， 342-1720 nm is the most at the extracting time of 3h， 16h， 24h， respectively (3)The diameter the micro/nano particles of wood extractives and hemicellulose is chiefly between 342nm and 6440 nm according to number fraction。Micro/nano particles in the diameter of 91。3-342nm， 91。3-342nm， 91。3-342nm is the most at the extracting time of 3h， 16h， 24h， respectively。
