解釋
無選擇性地設陷阱誘捕-
3. the trapping characteristics of ordinary helical gear pump are lucubrated by theory for the first time, the theoretic relation of the gear rotor between the end overlap coefficient and trapping phenomenon is discussed respectively with clearence or without clearcence, and the relation of trapping volume with the rotational angle turn is also discussed. the selective range of the helical angle that can eliminate completely the trapping of helical gear pump is gained, which never appeared in literature before
首次對普通斜齒齒輪泵的困油特性進行深入的理論研究，分別討論了有側隙和無側隙時普通斜齒齒輪泵轉子的端面重合度與困油現象之間的理論關系，以及困油容積隨轉角的變化關系，得到了完全消除斜齒齒輪泵困油沖擊的螺旋角機械科學研究院博士學位論文的選擇范圍。 -
In this paper we have predicted two kinds of new quantum coherence effects. one is the strong - field index enhancement via selective population trapping of dressed states and the other is the preservation of the coherent population trapping ( cpt ) is by quantum interference of incoherent pump processes
本文提出了兩類新的原子相干效應，一是利用選擇性修飾態捕獲產生強場折射率增強，二是非相干泵浦誘導的量子干涉保護相干捕獲。
