本文針對文本分類和問題分類的差別，利用依存分析提取主幹和疑問詞及其附屬成分，並結合主幹關聯詞對，採用支持向量機分類器，此方法大大減少了問題分類的噪音，突出了問題分類的主要特徵，並考慮了詞與詞之間的句法關系，取得了良好效果;同時，針對普通層次分類在問題分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分類新思想，利用句法分析提取分類特徵，在問題分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 % ，比傳統的層次分類分別提高了10個百分點，證明了此方法的有效性。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
應用由111個傳聲器組成的平面傳聲器陣列對當前流行的民用客機進場著陸過程中的機體噪聲源進行了實驗測量，本文對七架窄體客機和七架寬體客機的起落架噪聲進行了分析，得到了起落架噪聲的頻譜特性、指向特性和聲級變化.研究發現，起落架噪聲的頻譜是由寬頻隨機噪聲與一些較為明顯的單音噪聲源組成，起落架噪聲的指向性類似於一個水平放置的偶極子.不同飛機起落架噪聲的聲級相差較大，這說明可以通過重新結構設計降低起落架噪聲。The precise clock source is crystal oscillator made of 74hc04 ; the mute circuit can conceal the error and solve the problem of noise ; the antenna switching circuit in the receiver is to select one antenna from two which receives signal better. it can improve the quality of the receiving audio signal, restrain the noise effectively and promote the system performance
