An offensive backfield player whose position is behind the quarterback and halfbacks and who primarily performs offensive blocking and line plunges.

Imagine a football team winning the Super Bowl one year, and then losing to injury, free agency, or retirement its starting quarterback, and its best receiver, running back, defensive lineman, and cornerback, as well as its coach and half the front office, all over the course of the next season.

想象一个球队有一年赢得了超级杯大赛，（下面专业术语啊~真的很bt）败于伤病，自由球员市场或者四分卫，还有他最好的接球员、跑锋、防守线卫、守方后卫和教练、一半的管理部门的退职，充斥着下一个赛季。

We present the fundamental theories of Noether symmetries and conserved quantities of mechanco-electrical dynamical systems, including variation principle of the system, Noether symmetry transformation, Noether quasi-symmetry transformation, generalized Noether quasi-symmetry transformation, Killing equations, Noether theorem, the form of conserved quantity. And then the basic theory of Lie symmetry is advanced, including the determining equation, structure equation and the form of conserved quantity.

给出机电动力系统的Noether对称性和守恒量基本理论，包括系统的变分原理、Noether对称性变换、Noether准对称性变换、广义Noether准对称性变换、Killing方程、Noether定理和守恒量的形式；给出机电动力系统Lie对称性的基本理论，包括确定方程、结构方程以及守恒量的形式。

Chapter two proposes the unified form of Hojman"s conservation law and Lutzky"s conservation law. Firstly, the author introduces the general Lie group of transformations that the variations of both the time and the generalized coordinates are considered, derives the determining equation of Lie symmetry for the system, presents a new conservation law, which contains the Hojman"s and the Lutzky"s conservation law as two special cases, and obtains a condition to exclude trivial Hojmans conserved quantities.

第二章，Hojman定理和Lutzky定理的统一形式：首先，引入一般意义下的Lie变换群(即位型变量q_s和时间变量t同时变换)，给出系统的Lie对称性确定方程，提出一个新的守恒律，Hojman定理与Lutzky定理则分别是这个新守恒律在两个特殊情况下的推论，导出一个可排除平凡Hojman守恒量的定理，并分别讨论了Birkhoff系统和非完整系统的Lie对称性和Hojman守恒量，最后，讨论了Hamilton系统的梅对称性与Lie对称性的关系，给出了由梅对称性求Hojman守恒量的方法。

F0 |; E" s; _ One night after straining his left hamstring beating out a fielder's choice, Alex Rodriguez played a key role in helping keep Minnesota off the board, a frame that saw Wang walk three batters -- one erased by a caught stealing -- and allow a hit."

在昨天晚上因为野选而拉伤了左脚筋的A-Rod，也扮演了让双城在记分板上挂零的关键角色，当时小民保送了三名打者–其中一名盗垒被捕–而后又被击出一支安打，「那可能是今日最佳好球，」厚黑说：「如果那时没守下来，他们很可能会得个好几分。

To fill this gap, the enhanced Poincaré inequality was obtained by considering the additional conservation law of momentum and by rigorous estimate of integral inequality.

为解决这个差异，利用周期带域上的Eady模型的动量守衡的性质，通过变分方法和积分的精细估计，建立一个加强的Poincairé积分不等式，从而证明了Eady模型的线性稳定意味着非线性稳定。

L ord , you alone are my inheritance, my cup of blessing.You guard all that is mine.

天父， 你是我的产业，是我杯中的分；我所得的业分，你亲自为我持守。

Torre partially threw up the white flag when he put Miguel Cairo in leftfield in the eighth inning (he also wanted to give Johnny Damon's sore calves a few innings off). The sight of Cairo fighting the sun and trying to run down Mark Teixeira's long drive to left-center in the eighth -- it didn't seem like a fair fight for the career infielder -- kind of summed up the afternoon. The ball fell for a double, one of three on the day for Teixeira (4-for-5, three RBIs, three runs).王建民加油站 D0 f' u7 a- N

当Torre在八局时派Miguel Cairo去守左外野时，已经算是某种程度的举白旗投降了〔他也想让Johnny Damon疼痛的小腿能少用个几局〕，Cairo在八局时试著挡住阳光去追Mark Teixeira打到中左外野之飞球的画面〔当时看起来，对这位当了一辈子内野手的Cairo来说，实在不是一个公平的对决…〕，也算是为今天下午做了个总结，那个球最后落地形成二垒安打，也是Teixeira在这场比赛中打出的三发二垒打的最后一发，他今天五打数、四安打、打回三分、得三分。

And then,凯 if we are true to plan,分 our statures touch the skies.

如果我们格守计划，凙我们的身才能够触到苍穹。
