action by contact
解釋
接觸作用-
The ultrasonic dynamic contact of bolt - clamped transducer and rigid plane are modeled using hertzian contact theory, and the analyzing results reveal that the nodal plane of the bolt - clamped transducer is levitated in normal direction by the ultrasonic dynamic contact action, and the real area of contact of bolt - clamped transducer and rigid plane decreases in the same time
首先利用赫茲接觸理論建立了夾心式換能器和剛性平面的超聲動態接觸模型。通過對模型進行分析、求解表明，在縱向超聲頻率動態接觸作用下，換能器節面位置產生了上浮，換能器端面與剛性平面的動態真實接觸面積比靜態時減少了。 -
And the generalized homothetic composite action of metallogenic subsystems mentioned above formed the multiple - composite metallogenic system of the jiangda tectonic belt. the typical ore deposits of jiangda tectonic belt, such as dingqinnong, jiaduoling, renda etc, are contact metasomatic type deposits formed intracontinental rifting stage, and the tectonic - magmatic - hydrotherm of intracontinental orogenic stage superposed and rebuilt some preexistent ore body. their space distribution is controlled by composite intrusive rock belt of ne direction
對丁欽弄、加多嶺、仁達等典型礦床的研究表明，它們均為形成於陸內裂谷作用階段的接觸交代型礦床，陸內造山期的構造?巖漿?熱液作用疊加改造了先成礦體，礦床空間分佈受北東向復合侵入巖帶控制。 -
While a 3d assembly model of blade - disc structure was established, a finite element model for calculating the vibration characteristics during blade - disc coupling was set up by taking into consideration of the coupling action of contact stress between blade and disc
摘要在建立了葉片與輪盤三維裝配模型的基礎上，考慮了由於裝配產生的接觸應力與葉片輪盤之間的耦合作用后，建立了葉片輪盤裝配耦合的振動特性計算的有限元模型。 -
The investigation on the generation of fg is made by the derivation of equations of fg tooth, contact lines on tooth in meshing, plane of action and fillet surface, and by the visualization of contact lines, fg tooth surface and fillet surface
在面齒輪齒面生成的研究中，推導了面齒輪的齒面方程、加工中的齒面接觸線方程、嚙合面方程和過渡曲面方程;對齒面的接觸線、面齒輪的齒面和過渡曲面進行了可視化。 -
