  1. This study showed that the mt and sharpness of frequency tuning curves increased as the sound direction changed from contralateral to ipsilateral azimuthal angles. it suggests that sound direction effect on frequency tuning may be through the complex interplay between the excitatory and inhibitory inputs. the application of gaba ( a ) antagonist, bicuculline, lowered all mts but the application did not abolish direction - dependent variation in mt

    聽皮層的抑制性影響使大多數神經元在蝙蝠最敏感的聲源方位c - 40的頻率分辨能力明顯提高，同時使c - 40和i - 40的最低閾值的差別進一步增大，提高了信噪比，提高下丘聽神經元對聲源方位和最佳頻率的分辨能力。
  2. Based on local coupling mode theory of graded index optic fiber wave guide, the variation regularity of coupling output light has been deduced when sound wave acts on single mode optic fiber coupler. and a new idea has been proposed that a novel sensor can be applied on detection of acoustic / vibration. the sensing element of sensor is the melting area of single mode coupler in which the feasibility of the new - type optic fiber sensor has been proved in experiment

    本文從緩變光纖波導的局部耦合模理論出發，推導出了單模光纖耦合器耦合分光在聲波作用下的變化規律，提出了以單模光纖耦合器的熔融區為傳感元件的傳感器在聲振動信號檢測中應用的新思想，並實驗論證了這種新型光纖傳感器應用於實際的可行性。
  3. Slow variation in the pitch of a sound reproduction resulting from variations in the speed of the recording or reproducing equipment

    音符失真，聲音走音由於錄音或放聲裝置中速度的變化而引起的，在放聲中出現的較慢的音調變化
  4. Another variation of enhance - cd, differs from mixed - cd in that it holds computer data in the last track and the sound data starts from track 1

    的是將電腦資料放在最後一軌，聲音資料則從第一軌開始，此類
  5. Qiupuriver mandarinfish is a local breed under selecting and a famous brand of chizhou city, anhui province, which has a big reproductive population and culturing on a large scale ; it also possesses of sound features such as high growth rate and strong resistance. but none study has been carried on its genetic basis before. study on the genetic variation of qiupuriver mandarinfish, changjiang mandarinfish and wanfuhu mandarinfish with isozyme and rapd markers has important content, at the same time, it will bring new material to selection and application of the qiupuriver mandarinfish

    秋浦河鱖魚是我省選育中的一個地方品種，具有生長快、抗逆性強等優良特性，已形成一定的繁殖與養殖規模，並成為我省池州市重點推廣的名牌產品；但對其遺傳基礎的研究尚屬空白，本試驗對秋浦河鱖魚、長江鱖魚和萬佛湖鱖魚進行同工酶和rapd分析，以便為秋浦河鱖魚的選育與推廣提供基礎資料。
  6. Cheong elaborated said, " we have nothing against the dvb - t ( digital video broadcasting - terrestrial ) system proposed by the government. however, the consumer would not really enjoy low - cost set top boxes ( stbs ) or integrated digital tv receivers ( idtvs ) as we were led to believe. " what the government proposed for hong kong would be a unique variation of 8mhz dvb - t dtt standard with dolby ac - 3 sound system which is not exactly the same as that of europe nor the majority of the world s.

    電視助理總經理鄭善強先生解釋：我們對政府建議的dvb - t （ digitalvideobroadcasting - terrestrial ）制式沒有特別喜惡，但消費者未必真正享受到便宜的機頂盒或解碼器及綜合數碼電視機，因為政府建議香港採用之8mhzdvb - t數碼電視制式與及ac - 3的音響系統其實與歐洲及世界其他主要地區有異。
  7. Variation in sound signal strength

    聲信號強度變化
  8. Detected variation of amide and implied that the secondary structure of plasmalemma protein changed under sound stimulation. fourthly, the activity of plasmalemma h + - atpase increased under sound stimulation

    這些實驗結果說明， h + - atpase在聲波刺激下其活性的調控可能是通過可逆磷酸化模式進行的。
  9. By experiment, we found that the variation of gear case radiant efficiency with frequency keep accordance with that of simple one as a whole, but the radiant efficiency of gear case will go beyond any calculation result of empirical formula when the frequency is below 250hz. we also found that stimulation changes affect radiant efficiency little by varying speed experiment, and it can be ignored in engineering calculation. the rectangle structures as gear case, possess characters of both plane and ball, and their sound radiant efficiency lie between plane and ball region

    通過試驗發現，總體上變速箱輻射效率隨頻率的變化規律同簡單構件的輻射效率是一致的，但在250hz以下的低頻區域，變速箱的輻射效率大大高於任何一個經驗公式的計算結果；通過換檔試驗發現，激勵的改變對輻射效率的影響不很顯著，工程計算可以不予考慮；對于變速箱這類三個方向尺寸差別不大的結構，其輻射性質具有平板和球源的雙重特徵，輻射效率介於平板和脈動球源之間，據此提出在工程應用時可以取平板和脈動球源輻射效率的平均作為此類結構輻射效率的觀點。
  10. The song sound like a variation of a very old and familiar tune

    這首歌像是一個熟悉的舊曲調的變奏曲
