查询词典 u-turn

This invention concerns a current control process for a feed-in voltage converter, wherein a detected flux-inducing current component and a detected torque-inducing currrent component of an actual currrent vector of a rotating field machine are each controlled for a flux-inducing current component set value and a torque-inducing current component set value of the rotating field machine. To that effect, a control set-value (DELTA u*sp, DELTA u*sq) is determined, dependent each time upon a determined current component control deviation. From these, current components of an actual current vector are formed each time by overlay of a formed pilot value (u*spvor, u*sqvor). This invention also concerns a device for carrying out this process.

本发明涉及一种用于馈入电压式变流器的电流调节方法，其中分别将所检测的一感应式电机的一实际电流向量（i s 的磁通感应电流分量和一转矩感应电流分量i sq ）调节至该感应式电机的一额定电流向量的一磁通感应分量额定值和一转矩感应电流分量额定值，在这种情况下，分别根据所检测的一电流分量调节偏差计算出一调节器调节量（△u * sp ，△u * sq ），由这两个调节器调节量分别通过叠加所形成的一预控制量（u * spvor ，u * sqvor ）形成一额定电压向量的电压分量（u * sp ，u * sq ），本发明还涉及一种用于实施该方法的装置。

For example, U-space is uniformly regular and which makes it has fixed point property, U-space is uniformly non-square and thus super-reflexive, uniformly convex space and uniformly smooth space are U-spaces, and an Banach space is an U-space iff its dual space is U-space, etc. In1990s, a lot of work had been done on U-space theory, e.g., Tingfu Wang and Donghai Ji introduced the concepts of pre U-property and nearly U-property. Under the structure of Orlicz space, they made systematic investigation of these properties, and gave the criteria for an Orlicz space to have U-property.

U-空间具有一致正规结构进而具有不动点性质；U-空间是一致非方的，进而也是超自反的；一致凸空间和一致光滑空间是U-空间；Banach 空间为U-空间的充要条件是其对偶空间为U-空间，等等。20世纪90年代，国内外学者对U-空间理论做了很多工作，王廷辅，计东海等人先后引入了准U-性质与似U-性质的概念，并在Orlicz空间框架下对有关性质进行了系统研究，完整给出了Orlicz空间具有各种U-性质的判据。

For any two vertices u and v of a graph G, a u-v geodesic is the shortest path between u and v. The set I consists of all vertices lying on a u-v geodesic. For SV, I is the union of all sets I for vertices u, v∈S. The geodetic number g is the minimum cardinality among the subsets S of V with I=V.

对于图G内的任意两点u和v，u-v测地线是指在u和v之间的最短路。I表示位于一条u-v测地线上所有点的集合，对于SV，I表示所有I的并，这里u，v∈S，G的测地数g是使I=V的最小点集S的基数。

The ~(233)U and the measured sample are mixed gravimetrically, then the R_(58)=~(235)U/~(238)U and R_(38)=~(233)U/~(238)U in the mixture are measured simuhaneosly, and the R_(38) can be considered as an internal reference standard.

233U和被测铀样按不同重量比被混合，然后，同时测量混合样中R_(58)=~(235)U/~(238)U和R_(38)=~(233)U/~(238)U，而R_(38)可被看作是内参照标准。

ACT LIKE U KNOW BUT this wasn't posted yesterday it was posted in MAY and it is not a challenge to anyone or anything these are lyrics from a song that i really like i do not see any harm in this and it was not directed at anyone in particular, it was a general statement yes i have been silent and everyone thinks i am hiding but today there will be a press release and i hope u can all read from that and report the TRUTH and do some homework before trying to ruin someone's life, cuz that is exactly whut u are all doing to me putting false statements on the FRONT PAGE of newspapers and to others as well ONCE AGAIN yes i have made the statement of IF U FUCKS WID ME I GOTSA FUCK WID U this is but i had posted this from MAY 2007 not JAN 2008 PLEASE GET YA FACTS STRAIGHT!!!!!!!!

行动象U知道但这在5月昨天未被张贴它被张贴了，并且它不是挑战对任何人或任何这些是抒情诗从真正我的歌曲，如我没看见任何害处在这和它中特别是未被指挥在任何人，它是一个一般声明是我有是沈默，并且大家认为我掩藏，但今天将有新闻发布，并且我希望u装从那读的所有于罐中并且报告真相并且在设法之前破坏某人的做一些家庭作业生活，是确切地whut u是做对我投入假供词在头版报纸和对其他的全部的cuz 我是再次做了声明，如果这是的U与WID性交我I GOTSA性交WID U，但我张贴了此从2008日5月2007年不是1月请得到YA事实平直！！！！！！！！
