underground propagation 中文意思是什麼

underground propagation 解釋
地下傳播
  • underground : adj 1 地(面)下的。2 隱蔽的,秘密的。3 (電影,報刊等)標新立異的,試刊的,試驗性而非正式的。4 ...
  • propagation : 持續培養
  1. The propagation of these temperature changes into the underground is far deeper than that of the annual temperature variations.

    這種溫度變化對地下的波及深度遠遠超過年溫度變化的影響深度。
  2. Laws of propagation and attenuation of spherical stress wave in the geologic media have been studied in detail by means of mini - chemical explosion test in laboratory in this paper. the lows are fundamental to improve and develop theoretic models for underground explosions ( tamped and cavity decoupled ) on the stress wave propagation, safety and containment during the explosion

    運用微型藥量化爆模擬試驗可以比較深入、細致地研究地質介質中球形發散應力波的傳播、衰減規律,這對于改進、發展用於估算地下爆炸(填實和空腔解耦)應力波的傳播及安全封閉的理論計算模型是至關重要的基礎資料。
  3. 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。
  4. In this paper, the authors study the mathematical model for seismic wave propagation in complex underground medium, discuss the boundary element method for solving seismic wave equations in frequency - domain, and investigate the computational formation of separation of wave equations in frequency - domain

    摘要分析了復雜地下介質情形地震波傳播的數學模型,討論了地震波數學模型數值求解的頻率域邊界元方法,並得到波動方程頻率域邊界元法的離散化計算公式。
