由于树木生长不均匀，使各种树木的木材构造具有多样性，不同细胞体、细胞密度和细胞形状导致了木材材性和物理力学性能存在较大差异，木材细胞的变化影响着木材性质的变化，木材的性质又决定木材经济价值，并直接影响木材的加工和利用，由此对木材细胞结构分析研究就变得尤为重要。

Take DMSO swollen treatment and DEA-SO2-DMSO decrystallization treatment for example, the X-ray diffraction and the Tobolsky's intermittent stress relaxation of treated woods were determined during soaking in water, analyzed the effects of water on crystal degree and inter-cohesion of treated woods. According to these continuous relaxation curves measured in water with different temperatures, various thermodynamic quantities were obtained by using Eyring absolute rate theory, and reviewed the chemical reactions in wood which occur in different relaxation process. For the first time quantify these crosslinkings formed in the process of tensional relaxation by using the SMCIR intermittent stress relaxation way, and defined the cross-linking reaction types. In order to find out the contribute of drying to the fixation of deformation of chemically treated wood, stress relaxation of oven-dry untreated and treated wood was measured during the process of temperature elevation and descend, then analyzed the effect of temperature change on relaxation mechanism of treated oven-dry wood. According to continuous relaxation curves of oven-dry treated wood under various constant temperature, calculated the thermodynamics of relaxation process and discussed the mechanism of molecule change in wood, at the same time, also quantified these cross-linkings produced in wood by intermittent method and on the basis of which the model of molecular change during relaxation process of chemically treated was constructed.

Further more,at present,there are tess systemic professional references about intercepted and captured bark beetle during quarantine in China,so it\'s time to establish a database of morphologic characteristics of bark beetle for quarantine in order to help quarantine inspection officer correctly identify them.Together with DNA bar-coding technique,the database will greatly promote the ability in identifying intercepted and captured bark beetle during quarantine.

此外，由于小蠹科昆虫种类繁多，目前对检疫截获小蠹虫的鉴定工作存在较大困难，且比较系统地反映我国进口货物中截获小蠹虫的专业资料较少，因此，急需建立针对我国进口木材中小蠹虫检疫用的形态图谱以加强检疫人员对其的识别；并通过分子生物学分类技术的研究，辅以DNA条形码技术以提高对其的鉴定水平。

The persons who listen to a week all feel the minister prayer is very boring, but the TOM took out beetle to come out and play, however let it bittenned, then had a dog to discover this beetle, then played to get up with it, but when the dog was bitten by the beetle, then ran about, running to a director finally nearby, the host drop the outside of a window to it, bema persons all cannot helped but smiling at this time!

听礼拜的人都觉得minister的prayer很无聊，而TOM就拿出了beetle出来玩，不过让它咬了，然后侑一只狗发现了这只beetle，然后跟它玩了起来，但是狗被beetle咬伤了，然后跑来跑呿，最后跑到主任身边时，主人把它掉出窗外，这时教堂的人都忍不住笑了！
