  2. At the same time, because general hierarchical is not good on question classification, this paper proposes a new method for chinese question hierarchical classification. this method combines the key class features with the question syntactic features to classify questions. since this method extracts the syntax features and adds syntax information into question classification, at last, the precision of the coarse classes reaches 88. 25 % and fine classes reaches 73. 15 %, respectively improves nearly ten percent than the traditional hierarchy classification, proving this method is effective

    本文針對文本類和問題類的差別,利用依存提取主幹和疑問詞及其附屬成,並結合主幹關聯詞對,採用支持向量機,此方法大大減少了問題類的,突出了問題類的主要特徵,並考慮了詞與詞之間的句法關系,取得了良好效果;同時,針對普通層次類在問題類上效果不理想的情況,本文提出了類別主特徵結合句法特徵的中文問題層次類新思想,利用句法提取類特徵,在問題類中融入了句法信息,總的準確率達到大類88 . 25 %和小類73 . 15 % ,比傳統的層次別提高了10個百點,證明了此方法的有效性。

  4. A large planar microphone array, which consists of 111 microphones, was successfully applied to obtain a two - dimensional mapping of the sound sources on a landing aircraft. the focus of study in this paper is on the landing gear noise source. the spectra, directivities and sound pressure levels of flap side - edge noise of 7 narrow - board commercial aircraft and 7 wide - board commercial aircraft are presented. it is found that the landing gear noise spectrum is broadband with some single tones in some cases. the directivity of the total sound pressure level of a landing gear noise resembles that of a horizontal dipole. the level differences between the various aircraft landing gears are larger than those expected from the airspeed differences. it is thus expected that the louder noise emission of the landing gears can be reduced by redesigning
