  1. Using the system designed in this thesis work, flow field calibration of the wind tunnel is accomplished, which covers dynamic pressure drop coefficient, dynamic pressure time stability, axial static pressure gradient, boundary layer, and degree of turbulence, etc. boundary layer measuring principle and method are especially described in detail, the relationship between boundary layer thickness, wind speed setting, and the depth of the experimental section is summarized, and finally the calibration data for th e model center zone under specific wind speed are given

    然後利用本文設計的系統完成了落差系數、動壓時間穩定姓、軸向靜壓梯度、邊界層及湍流度等內容的流場校測。特別對邊界層測量的原理及方法做了較詳盡的敘述，總結出邊界層厚度與設定風速、實驗段深度的關系，然後給出模型中心區一定風速下校正數值。
  2. 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。

  4. Rainfall and vertical profile of hydrometers are retrieved for land and ocean using tmi 1b11 data. the comparison of retrievals of gprof v6. 1 and v6. 2 with ground - based radar and gauge data on land and pr data on ocean show that the gprof - v6 algorithm can retrieve rain intensity much well and indicate vertical distribution of hydrometers mainly. as far as retrieved precipitation area, it is better for convective precipitation type than stratified precipitation type
