  1. This paper also show a rough estimate of the gains of this array, because it needs one year ' s data to collect one year ' s noise correlation variation curves and then give a more practical detection ability of the seismic array. one result of this paper is " seismic array site survery data processing software " exploited by the author. the software can calculate the power spectrum of noise for every site, noise coherence function for every site pair, the cross - correlation curves, the root mean square of noise for every site and the array response

    此外還計算了該臺陣的臺陣響應，發現臺陣響應的主瓣高而尖；旁瓣很小，這歪姐鈕遠宣腔撾踏數公鍍壁韶逼上攏唆精確啻應：有關此臺陣的檢測能力，只能給出一個粗略的估計，因為評價一個臺陣對地震事件的檢測能力需要獲得為期一年的觀測資料，才能給出一年內噪聲場變化的相關值曲線，最終給出更加符合實際的臺陣檢測能力。
  2. Passive suspension, pid control semi - active suspension and neural network control semi - active suspension are researched by simulation. white noise, sine wave and sawtooth wave are used for excitation. the root mean square value of vehicle body acceleration, suspension displacement and vehicle wheel load are analyzed

    在模擬研究中，路面激勵取為白噪聲、正弦波和鋸齒波，懸架類型採用被動懸架、 pid控制半主動懸架、神經網路控制半主動懸架三種。
  3. Welch, 1967 ), the author calculated noise power spectrum of every site to see if the noise level of the array site accord with ims standard ( the noise level at 5 hz must lower than - 135db ), and the result suggest that the noise level accord with the ims standard. to find out the principle of noise ' s variation, the root mean square of every site had been calculated and analysised, the result show that several sites had obvious daily variation which is relevant to the tv transmittion tower on the top of dajianshan

    Welch ， 1967 ）對臺陣陣址各測點的噪聲功率譜進行了計算與分析並對各測點的噪聲均方根值做了計算，結果表明臺陣的背景噪聲達到了ims要求的標準（即在5hz處噪聲功率譜要小於- 135db ） ，多數測點的噪聲有明顯的日變化規律，這與大尖山頂的tv發射塔有關。
  4. The method of calculation atmosphere noise is discussed and the detailed root mean square numeric values of different time of summer are obtained

    在計算出不同頻率下地波場強的同時，重點介紹大氣無線電噪聲場強的計算方法，並給出相關海域上夏季不同時段內大氣噪聲場強的有效值。
