  1. 英国欧洲赤松木材尺寸稳定化的研究

    Study on dimensional stability of Scots pine wood in United Kingdom

  2. 处理4周后,Cr仅在欧洲赤松中完全固定,在银杏和山毛榉中Cr的固定较好,而牡竹的Cr流失量仍为4%。

    After 4 weeks complete fixation of chromium took place only in pine . In beech and ginkgo the chromium was fixed to a higher extend whereas for bamboo about 4 % of the chromium content was leached .

  3. 为研究CCA防腐剂的固定性能,用银杏,欧洲赤松,山毛榉和牡竹进行比较试验。根据德国标准(DIN52172Ⅱ-1977),试验设置1周、2周和4周的不同处理。

    The fixation of a CCA-preservative , type B in Ginkgo , scotch pine , beech and bamboo has been tested in comparative laboratory investigations according to the German standard DIN 52 172 part 2 ( 1977 ), 1 , 2 and 4 weeks after impregnation .

  4. 树木气候学及其研究方法&兼论欧洲赤松年轮宽度与太阳活动的关系

    Dendroclimatology and it 's research methods

  5. 德国W.Lange在研究不同地区来源的欧洲赤松松脂的化学组成时,曾按△~3-蒈烯含量不同,将它们分成中欧和南欧地区二类。

    P. sylvestris was classified into two groups-central Europe and south Europe based on amounts of △ ̄ 3-carene in oleoresins of trees from different latitudes by W. Lange .

  6. 本文研究俄罗斯境内的欧洲赤松松脂的组成,发现它与同纬度的中欧地区欧洲赤松松脂一样,含有较高数量的△~3-蒈烯。

    This paper studied the chemical compositions of oleoresin from P. sylvestris grown in Russia . It contains high amounts of △ ̄ 3-carene like that in central Europe at the same latitude .

  7. 我们于1980年开展了欧洲云杉、日本冷杉、欧洲赤松等几种工业用材针叶树种引种选择研究。

    We developed a study on introduction and selection for several kinds of industrial timber conifer species such as European spruce , Japanese fir and Scotch pine .

  8. 研究结果表明:欧洲云杉、日本冷杉、欧洲赤松的生长量分别比对照油松大16%~28%,19%,228%。

    The result shows that increment for European spruce , Japanese fir and Scotch pine is 16 % ~ 28 % , 19 % and 22.8 % higher than that of contrast Chinese pine in order .
