木材燃烧与建筑火灾

木材的应用极为广泛，在每一座建筑结构中，木材有可能已被用作建筑构件，也可能附属在其它材料上变成具有特定功能的物品，由于木材属于易燃材料，这就注定了它与建筑火灾结下的不解之缘。一旦发生火灾，这些充斥于房间中数以分斤计甚至百公斤计的木材，对火灾将起推波助澜的作用。

Bioeffects of Low Energy Ion-Beam Implantation and Vacuum Treatment on M1 Arabidopsis Thaliana

Vacuum treatment and ion-beam bombardment are two major processes in the low energy ion-beam implantation. To accurately study the contributions of these two major factors to the bioeffects separately, the M1 generation variation of Arabidopsis thaliana with ion-beam implantation and vacuum treatment were compared through a series of key plant development parameters including morphological observation, biochemical assay and RAPD （random amplified polymorphic DNA） analysis. The results showed that ion-beam implantation had obvious effect on almost all of these parameters, and the vacuum treatment had some impacts on several morphological parameters such as the bolting time and the length of the primary stem. Taking the results together, the indication is that vacuum treatment has some slight contributions to the bioeffects of ion-beam implantation while ion-beam bombardment itself is the major creator of the bioeffects.
