向后

This section presents two kinds of characteristic schemes, one is the natural use of the usual backward Euler characteristic difference scheme ( [60] ) onto the triangular mesh, the other replaces the backward Euler's method by modified Euler formula to approximate the characteristic differential equation, so that the discretization for characteristic curve can get up to second order accuracy.

本节给出了两种三角形网格上的特征差分格式，第一种是通常的向后Euler型特征差分格式（[60]）在三角形网格上的自然运用，第二种采用§3.3、§3.4的离散思想，使用改进的Euler公式代替向后Euler公式来近似特征微分方程，使其对特征线的离散达到了二阶精度。

Before going to bed at the hairline from the forehead back comb the scalp at the hairline, hands the little finger connected to the other four fingers naturally separated along the top of the head backward in order, so you can make facial massage to a transparent and eliminate fatigue, promote sleep Gallbladder Meridian .

睡前从前额发际线处向后发际线处梳理头皮，双手小指相连，其余四指自然分开，沿头顶向后梳理，这样可以按摩到使面色通透、消除疲劳、促进睡眠的胆经。

Douglas and Russell first presented the idea of characteristics in[13],in whichthe diffusion term is included in the derivative of characteristic direction of the solu-tion and the backward difference quotient along the time axis was replaced by it alongcharacteristic direction.

Douglas，Russell[13]最先提出了特征法的思想，其主要特点是将模型方程的对流项隐含在解沿特征方向的导数之中，以沿特征方向的向后差商逼近取代通常方法中沿时间方向的向后差商逼近。

While using three—points backward finite difference to imitate the radiation condition, we accept Raven's〓 idea to shift collocation points upstream a short distance.

在用三点向后差分格式模拟辐射条件时，接受了Raven〓的建议，将单元控制点向后移动了一段距离。

It is, but in a different way to how previous versions of HTML were backwards compatible.

XHTML不是向后兼容的，但这只是与早前版本的HTML在向后兼容的方式上不同而已。

Like a wild beast mortally wounded, bleeding and licking its wounds, for five weeks the French remain in Moscow, attempting nothing; and all at once, with nothing new to account for it, they flee back; they make a dash for the Kaluga road (after a victory, too, for they remained in possession of the field of battle at Maley Yaroslavets); and then, without a single serious engagement, fly more and more rapidly back to Smolensk, to Vilna, to the Berezina, and beyond it.

他们犹如受了致命伤的野兽，流着血，舔舐着伤口，五个星期呆在莫斯科毫无动静，突然，毫无缘由地向后逃跑；窜向卡卢日斯卡雅公路，同时，（在打了胜仗之后，因为小雅罗斯拉维茨城附近的战场对他们有利），一仗也不打地退得更快，退向斯摩棱斯克，退离斯摩棱斯克，逃至维尔纳，逃至别列济纳河，向更远的地方逃跑。

In Chapter 3, we discuss the structured backward error and condition numbers of saddle point problem.

第三章讨论鞍点问题的结构化向后误差和条件数，给出了鞍点问题结构化向后误差的一般表达式，并用结构化条件数分析了解的敏感性。

Note this is not the next 3 generations of S + space, but W + space, but the rhythm and the 3rd generation to unanimously. 3 behalf of the ghost dance is to take advantage of the principle of inertia back out quickly jump backward, rather than phenotypes.

注意这里不是接3代的S+空格，而是W+空格，但是节奏要和3代一致。3代鬼跳的原理就是利用向后跳出的惯性迅速的向后跳出，而不显型。

Our eyes are placed in front because it's more important to look ahead than to look back.

我们的眼睛长在前面是因为向前比向后看更重要，如果你向后看你的旅程已经结束。
