  1. " she was a - visiting there at booth s landing, and just in the edge of the evening she started over with her nigger woman in the horse - ferry to stay all night at her friend s house, miss what - you - may - call - her i disremember her name - and they lost their steeringoar, and swung around and went a - floating down, stern first, about two mile, and saddle - baggsed on the wreck, and the ferryman and the nigger woman and the horses was all lost, but miss hooker she made a grab and got aboard the wreck

    正是黃昏時分，她和黑女傭上了渡騾馬的渡船，準備在一個朋友家住一晚上，那個朋友叫什麼什麼小姐來著，名字我記不住了。渡船上的人丟了掌舵的槳，船就打圈圈，往下游漂去，船尾朝前，漂了兩英里多路，碰到那條破船上，就給撞翻了。擺渡的和黑女傭以及一些馬匹，全都沖走了。
  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。
  3. 3. edge detection and threshold segment are used in safe landing area choice

    3 .採用邊緣檢測和閾值分割方法進行軟著陸安全區域選取。
