deriving form 中文意思是什麼
-
A circuit arrangement for deriving a phantom circuit. in four wire circuits, the two wires associated with the " go " channel form one " side circuit ", and those associated with the " return " channel form another
用來派生一個幻象電路的電路結構。在四線電路中，與「去程」通道相關聯的兩線就形成了一個「半邊電路」 ，而與「回程」通道相關聯的兩線構成了另一個「半邊電路」 。 -
The reed pen and the feather writing brush after the evolution, spreads by the fountain pen form until now, and is unceasingly deriving the new written tool branch
蘆葦筆和羽毛筆經過演變，以鋼筆的形式流傳至今，並不斷派生著新的書寫工具分支。 -
In terms of deriving the maximum trapped - wavelength and the critical emitting angle of elevation for electromagnetic wave which can forms duct propagation and introducing the four kinds necessary condition for electromagnetic wave to form duct propagation, under these conditions we now have the radio wave bent back towards the earth
結果與實際觀測到的波導傳播時的回波結構相同，說明，根據不同的大氣層結，利用電磁波的波導傳播的射線追蹤方法可以基本上確定電磁波的傳播軌跡。 -
When discreting the sonic and elastic analytic equation, the paper shows different finite - difference forms of sonic and center finite - difference form of elastic by detailed deriving in different situation. at the same time, the paper discusses the finite - difference ' s stability and the boundary conditon of gridding region, then lists the final sonic and elastic finite - difference expression which can realize forward modeling and inverse in computer by programming
在對聲波與彈性波解析表達式進行離散時，論文按不同情況進行了詳細的推導，由此得到聲波方程各種不同的差分格式和彈性波的中心差分格式，在此基礎上還對差分方程穩定性條件與網格區域邊界處理進行了討論，最後得到完整的能在計算機上進行正反演編程運算的聲波與彈性波有限差分格式。
