  1. In attempt to directly compare the sound response characters of the same bf neurons or different bf neurons and their interactive relation, the double recording microelectrodes were penetrated into two different neurons in iso - frequnency laminas or hetero - frequency laminas. taking advantage of frequency tonotopical arrangement in 1c of bats, it was explored how the neurons integrated different parallel processes of the same sound information. in the case of which, we hoped to explore the relation between the sound response characters of the central auditory neurons and neural modulation in background noise for the further understanding of the mechanism in the central auditory neurons extracting sound signals

    本研究以大棕蝠( bigbrownbat , eptesicusfuscus )為模型,利用ic調組構排列成同頻層這一結構特點,突破單極記錄和檢測神經元的方法,同時推進兩單極至一個同頻層或兩個同頻層的兩個不同神經元,試圖從細胞水直接比較兩個具有相同和不同最佳頻率的神經元信號的加工處理特徵、以及它們之間的相互關系,以期窺探它們在對同一信號處理過程中的整合奧秘,並以此為基礎分析和探討條件下中樞神經元反應特徵與神經調制的關系,以期進一步了解中樞聽神經元信號提取的機制。
  2. But, the eeg signal that we can acquired is very weak and is badly contaminated by strong background noise, such as electrooculogram ( eog ), electrocardiogram ( ecg ), and line noise ( 50hz or 60 hz power frequency interference ), etc. eeg is a typical non - stationary random signal with a certain extent of non - gaussian and non - linear character

    但是我們能夠獲得的腦信號一般非常微弱、並伴有很強的,是一類典型的非穩的隨機信號,且存在一定的非高斯性和非線性。傳統的分析處理方法一般將腦信號近似認為是線性的準穩的高斯分佈隨機信號,這使得分析結果往往不能令人滿意、實用性差。
  3. The first one references the principle and methods of small aperture beam technique. the sr measurement of aero - flow medium which fit the quasi - frozen - flow assumption was analyzed. the second measurement the deflection of s - h sensor ’ sub - aperture wave - front, according to spectrum calculation, sr can be gotten also

    特別注意在實踐中具有操作意義的關鍵方法:設置一定閾值后,和讀出的影響可以降低,從而提高質心探測精度,在實踐中可以找出一個最佳閾值。
