Study on the main characteristics of underground explosion seismic source function in granite 花崗巖介質中地下爆炸震源函數研究
This makes the svg easier to read when using the view source function of an svg viewer 開始,這樣可以保證使用svg查看器的“查看源代碼”功能時, svg更容易閱讀。
The stability of stagger - grid , boundary conditions and the source function implementation are discussed 討論了差分格式的穩定性、邊界吸收條件以及聲源函數的選取。
2 ) the effects on waves conversion are stronger in rocks with dry fractures than that in rocks with water - filled fractures , and s - waves attenuate more rapidly in rocks with water - filled fractures . 3 ) the explosive point source which locates in anisotropic media can excites not only p - waves but also s - waves . 4 ) the properties of waves propagation were discussed and compared for several point sources with different source functions 結果表明: 1 )平行排列裂縫造成的各向異性使波前變寬; 2 )含干裂縫巖石對波型轉化的影響比含充水裂縫巖石的大,橫波在含充水裂紋中傳播時衰減較快; 3 )當介質存在各向異性時,爆炸點源產生的波不僅有縱波,還有橫波; 4 )通過改變點源函數研究不同點源所產生波以及波型的轉換。
In the suspended sediment transport model , the method of shear stress is adopted to determine the source function in the suspended sediment diffusion equation . through a series numerical experiments and statistical analyses of observed field data , a local coefficient , which can reflect the bottom material and consolidation , is introduced into the classic critical erosion velocity of the sediment 懸沙輸運模型利用切應力方法來確定對流擴散方程中的泥沙源函數,其中的臨界起動速度利用經典的泥沙起動流速公式前面增加一個局地系數得到,這個系數能反映河床底質結構及固結程度,通過系列數值試驗和實測資料的統計分析確定。
百科解釋
The source function is a characteristic of a stellar atmosphere, and in the case of no scattering of photons, describes the ratio of the emission coefficient to the absorption coefficient. It is a measure of how photons in a light beam are removed and replaced by new photons by the material it passes through.
