查询词典 enveloping ring

When the system starts, the speed outer ring saturats non-functional, the current inner ring plays a major role to regulate the starting current to maintain the maximum so that the speed linear change, to reach a given value; when it operates steadily, the speed negative feedback from the outer ring plays a major role ,to let the speed changes with the given speed voltage , at the same time the current inner ring regulates the armature current of motor adjustment to balance the load current.

在初步观察泄漏量、判断泄漏部位的基础上，再手动盘车观察，若泄漏量无明显变化则静、动环密封圈有问题；如盘车时泄漏量有明显变化则可断定是动、静环摩擦副存在问题；如泄漏介质沿轴向喷射，则动环密封圈存在问题居多，泄漏介质向四周喷射或从水冷却孔中漏出，则多为静环密封圈失效。

杂质泵安装静试时泄漏机械弥缝安装调试好后，一般要进行静试，察看泄漏量如泄漏量较小，多为动环或静环弥缝圈存在问题；泄漏量较大时，则表白动、静环磨擦副间存在问题在开端察看泄漏量、判断泄漏部位的根蒂根基上，再手动盘车察看，若泄漏量无明显变化则静、动环弥缝圈有问题；如盘车时泄漏量有明显变化则可下定论是动、静环磨擦副存在问题；如泄漏介质沿轴向喷洒，则动环弥缝圈存在问题居多，泄漏介质向四周喷洒或从水冷却孔中漏出，则多为静环弥缝圈失效此外，泄漏通道也可同时存在，但一般有主次区分，只要察看细致，认识结构，一定能正确判断

Especially, it is found that there exists three types of relative permeability of water such as concave, convex to the water saturation ax and the reversed "S" pattern. The super-low permeability reservoir is sensitive to pressure, apparent with millipore undersaturation and water blocks. In this study, a new concept of irriducible undersaturation is brought up. And a new mode to describle the process of imbibition dynamics is used to reveal and confirm the mechanism of pinhole enveloping macropore as following: pendular ring of wetting phase gathers→it fills throat→it truncates nonwejting phase . The expression of pressure distribution and the equation of oil production are deduced under conditions of non-darcy linear seepage and non-linear seepage.

The results of UV absorption show that λ max is not sensitive to the electronic effects exerted by the substituent in the coupler moiety. The λ max has a small red-shift when the anilide aromatic ring in the coupler moiety is larger. This indicates that the conjugation effect of the anilide ring with chorosorb is not very significant. It is important to note that a red-shift of 60-130 nm was observed when the coupler component changed from a 2-hydroxy-3-naphthanilide to a 2hydroxy-11H-benzocarbazole-3-naphthanilide coupler. The red-shift may be due to the conjugation resulting from the carbazole ring.

对上述三个系列偶氮染料吸收光谱的研究结果表明，偶合基酰胺芳环共轭环的扩大对偶氮染料在可见光区最大吸收红移作用不是很显著；当偶合基萘环上共轭环扩大了一个咔唑环后，其偶氮染料在可见光区的最大吸收大幅红移，跨入近红外染料行列，这一结果对红外偶氮染料的设计合成具有重要的参照价值。
