To use eucalyptus as solid wood products in value-added way instead of wood chips for pulp and paper, the sawing characteristics of E. grandis was studied, the strain changes in sawing process, bow deformation and end-splits of lumber were analyzed. The results showed that the sawing strain changed in a random way, but the bow deformation had an evident regularity, the lumber near its bark had a big bow deformation. The end-splits had severe influence to lumber recovery, 15% of lumber recovery was influenced by end-splits. The results also indicated that planted E. grandis was a potential wood species as solid wood utilization in the fast-growing plantation.

人面桃花  人面桃花,出自唐·崔护《题都城南庄》诗:“去年今日此门中,人面桃花相映红。人面不知何处去,桃花依旧笑春风”。据唐朝孟綮《本事诗画·情感》载:唐人崔护,清明日独游长安城南,见一人家桃花绕宅。崔叩门求水,一女子予之,两人一见倾心。第二年,崔又去该地,但人未见,门已锁。崔即题诗于左扉。后来人们以“人面桃花”形容男子怀念一见钟情后不能再度相间的女子。  “人面桃花”给人留下一个美好的回忆。但在
