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。

From the results, it was found that sufficient resorcinol was needed for PRTF copolymer resins to have cold-setting property. The PRTF copolymer resins made from Taiwan acacia bark extractives with P/=1/1 had cold-setting capability at the ratio of resorcinol to bark extractives was 25/75, but 50/50 was needed for China fir bark extractives to have cold-setting property.

由试验结果得知，PRTF-B共聚合树脂中仍须有足够的间苯二酚始可具备常温硬化性，以相思树树皮萃取物为原料者，在P/=1/1时，间苯二酚与树皮萃取物之比例为25/75者具常温硬化性，而以杉木树皮萃取物为原料者，则间苯二酚与树皮萃取物之比例则须50/50始具有常温硬化性。

A fragrance introduced by the sensuality of birch wood, bergamot and bitter orange; juniper wood and artemisia mingle with cardamom, underlined by cold spices for the middle note; the base note finally emerges, sensually, releasing oak, cedarwood and vetiver, as an echo of the birch wood.

前香味以桦木、柠檬和苦柑橘为主，洋溢著感性的芬芳；中段以刺柏木、艾与小豆蔻为主调，搭配温凉的辛香；后段则由橡木、松与岩兰草所组成，逐渐散发出感性的馥郁，回应前段的桦木香。

Instead of calling on some scholar, I paid many a visit to particular trees, of kinds which are rare in this neighborhood, standing far away in the middle of some pasture, or in the depths of a wood or swamp, or on a hilltop; such as the black birch, of which we have some handsome specimens two feet in diameter; its cousin, the yellow birch, with its loose golden vest, perfumed like the first; the beech, which has so neat a bole and beautifully lichen-painted, perfect in all its details, of which, excepting scattered specimens, I know but one small grove of sizable trees left in the township, supposed by some to have been planted by the pigeons that were once baited with beechnuts near by; it is worth the while to see the silver grain sparkle when you split this wood; the bass; the hornbeam; the Celtis occidentalis, or false elm, of which we have but one well-grown;some taller mast of a pine, a shingle tree, or a more perfect hemlock than usual, standing like a pagoda in the midst of the woods; and many others I could mention.

我并没有去访问哪个学者，我访问了一棵棵树，访问了在附近一带也是稀有的林木，它们或远远地耸立在牧场的中央，或长在森林、沼泽的深处，或在小山的顶上；譬如黑桦木，我就看到一些好标本，直径有两英尺：还有它们的表亲黄桦木，宽弛地穿着金袍，像前述的那种一样地散发香味，又如山毛榉，有这样清洁的树干，美丽地绘着苔藓之色，处处美妙呵，除了一些散在各地的样本，在这乡镇一带，我只知道有一个这样的小小的林子，树身已相当大了，据说还是一些被附近山毛榉的果实吸引来的鸽子播下的种子；当你劈开树木的时候，银色的细粒网闪发光，真值得鉴赏；还有，椴树，角树；还有学名为Celtis occidenta lis的假榆树，那就只有一棵是长得好的；还有，可以作挺拔的桅杆用的高高的松树，以及作木瓦用的树；还有比一般松树更美妙的我们的铁杉，像一座宝塔一样矗立在森林中；还有我能提出的许多别的树。

This paper took the insect-resistant transgenic birch grown in greenhouse for four years as study materials. The genomic DNA and RNA of leaves were extracted and the integration and the expression characteristic of the extraneous genes in the insect-resistant transgenic birch were analysed by methods of multiplex PCR, reverse primer PCR, inverse PCR, RT-PCR, and insect-feeding experiment of the transgenic plants respectively.
