其特點集中體現在三個方面:在天線徑向通過八木天線的形式獲得增益;充分利用基站空間在z向組成陣列獲取陣列增益;利用開關八木天線方向圖可重構的特性，通過合理的布局，在方位面內實現角度分集。Integrated the monitoring data collected from the scene of blast with the correlative theory of earthquake wave, the blast vibration characteristic of this underground blast engineering and the influence that the blast vibration act on the ground buildings are analyzed. applied the method of duality linearity regression analysis, the propagation attenuational laws of blast earthquake wave in this underground engineering are gained by this software matlab. the analysis results indicat that the attenuational laws of blast earthquake wave are obvious diversity in the condition of difference distances
結合採集到的大量爆破振動現場實測數據，並應用地震波的相關理論，分析了該地下工程開挖爆破的地面爆破振動特性及爆破振動對地面建（構）築物的影響;應用二元線性回歸分析法，通過matlab軟體計算得出該地下工程開挖爆破地震波的傳播衰減規律;分析結果表明，不同距離下的地面爆破地震波的衰減規律存在明顯的差異，近距離條件下爆破地震波的垂直方向分量衰減最慢，遠距離條件下垂直方向分量衰減最快，遠距離的爆破地震波的垂直方向分量和水平徑向分量的衰減指數均要比近距離相應的爆破地震波衰減指數要大。In the process of the software development of well test interpretation, a method for early - stage ( pure wellbore storagy, fracture linear flow, fracture - formation dual linear flow ) and radial flow stage parameters interpretation is proposed
