Therefore, on the basis of objective description of corpus example, this paper study and analyze the condition of "free form" and "bound form" of the verbal phrases such as "V + Particle + N"、"V+ complement"(including:"V+ trend complement","V+ result complement","V+ extent complement" and "V+ action-measure complement )、"V TO V"、"V+ adverb+ V"、"V of V "and "V+ D".At the same time, from the semantic and pragmatic perspective this paper discuss the conditions and causes from "bound form" to "free form",concluding that particle dynamics、exclamation at the end of the sentence、adverb and follow—up of the language and so on can act as the conditions from the bound verbal phrase to the free verbal phrase. The main reason for these conditions is rich in the amount of the sentence, making semantic self—contained; Finally, this paper simply describes the theoretical and practical significance of the phenomena of "free form" and "bound form in the aspect of verbal phrase; at he conclusion of the article, the author of the text further sum up the content and coverage and raise her own views of the text of underdevelopment and the questions yet continuing to study.

因此，本文接着在语料例证的客观描述基础上，针对"v+动态助词+N"、"V+补语"(包括："V+趋向补语"、"V+结果补语"、"V+程度补语"、V+动量补语)、、"V来V去"、"副词+V"、"V的V"、"V+D的"等动词性短语的"粘着"和"自由"的情况做了探讨分析，并且从语义和语用两个角度探讨了"粘着"向"自由"转化的条件及原因，认为动态助词、句末语气词、副词、后续语段等等都可以充当粘着的动词性短语向自由的动词性短语转化的条件，其主要原因则是这些条件丰富了句子的信息量，使得语义自足；最后，文章简要地论述了研究动词性短语的"自由"和"粘着"现象的理论意义和实践意义；在文章的结语部分，作者就文中所论述的角度和涵盖的内容做了进一步的总结，并对文中存在的不足和有待于继续研究的问题提出了自己的看法。

The main reason why quarter-sawn board of Birch had smaller dry compressing shear strength than flat-sawn board of Birch in normal conditions was that Birch had different shear strength to the grain between quarter-sawn board and flat-sawn board. Meanwhile xylary rays in flat-sawn board were transversely cut and left a lot of pores in the flat-sawn board, so adhesive can enter these pores and turn into adhesive nail. While these pores provided a kind of tunnel for water, so cause this phenomenon that wet compressing shear strength of flat-sawn board of Birch was smaller than that of quarter-sawn board of Birch. The possible reason why quarter-sawn board of Oak had greater dry compressing shear strength than flat-sawn board of Oak in normal conditions was that ratio of springwood on quarter-sawn board and flat-sawn board was different.

造成柞木径切板的常态压缩剪切强度比弦切板的常态压缩剪切强度大的主要原因是，在径切板和弦切板上早材胶接的比例不同，径切板的胶合强度试件上早材胶接的比例相对少，而弦切板的胶合强度试件上早材胶接的比例比径切板的胶合强度试件上早材胶接的比例相对大，由于早晚材胶接过程中强度决定于早材，这部分胶接强度比较低，这就使得柞木径切板的常态压缩剪切强度比弦切板的大；同时在柞木弦径面胶接过程中由于实际胶接面积的不同也能造成弦径面上API胶粘剂与之形成的化学键的数量不同，这也是造成柞木径切板的常态压缩剪切强度比弦切板的大的原因之一。

The increase in specific surface area accounts for only a small part of it; e.

比表面积的增加也是一个原因，但不是主要原因； e。

It is concluded from the analyses made that the leakage from the SF6 switch pneumatic mechanism at the switch field of Hegang Power Plant is caused by the poor quality of compressed air.
