Shaul Mofaz, an Israeli parliamentarian and former army chief of staff, says a radical axis of Iran,Syria, Hezbollah and the Palestinian militant group Hamas in Gaza are trying to destabilize the Middle East.

In the meantime the Eiffel Tower is a wonderful way of showing the degree to which the vertical axis is virtual.
与此同时,埃菲尔铁塔,很好地向大家展示了,竖轴在何种程度上是虚拟的。
So in the partnership game we put efforts on these axis and now I'm going to put quantities on these axis.
合伙人博弈中横轴表示付出的努力,现在横轴表示的是产量
But the two others axis, per the syllabus that we'll explore in great detail in the course and also these are the axis along with which we'll evaluate your submissions are design, in other words how well implemented is this?
但是另外两个中心线,按照教学大纲我们将探究,课程中格外的一些细节,这些中心线是跟,我们评估你们的设计论文是一致的,换句话说,这个执行得怎么样?
So even though we see a nodal plane down the center, I just want to really point out that it's only when we have a nodal plane in the internuclear or the bond axis that we're calling that a pi orbital.
虽然在中间有个节面,我想要指出的是,只有节面在核间轴,或者键轴上时,我们才叫它π轨道。
But once in awhile, one of these plus twos comes in almost on axis, and it gets whipped around by the Coulombic repulsive forces.
但是偶尔一个带两个正电荷的粒子,以接近于轴的位置进入,会快速的移动到周围,由于库仑斥力的作用。
Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.
平面上面的点的方法,也就是极坐标,上面那种方法其实是,如果你们喜欢我这么说的话,笛卡尔坐标表示法。
By the way, I'm going to leave also to your sections the strange confusion that ensues in taking a rhetorical device, metonymy, and making it synonymous with grammar on the axis of combination.
另外,我还将把奇怪的困惑留给你们思考,这个困惑随着使用修辞学策略和转喻而产生,并使得它在结合轴上与语法有着同样的意思。
The components come in the minute you pick your axis.
但它的分量由你所选择的坐标系确定
It dropped dramatically in the period from 1954-- this is these filled black bars refer to this axis, polio cases per 100,000 population dropped down to only three or four cases by 1956.
患病率在一九五四年后的,一段时间里急剧下降,该坐标轴上的这些黑色柱形图表明,到一九五六年,小儿麻痹症的发病率,已经降低至每十万人中仅三到四人发病
On one axis you have dietary fat, the other you have how much-- in fact I should have brought the graph but I didn't-- how much breast cancer there is in the society.
其中一个轴是膳食脂肪摄入量,另一个轴是,事实上我应该把图表带来的但没有,社会上的乳腺癌病例数量
If we're talking about a single bond, we're talking about 2 orbitals overlapping in the internuclear axis.
如果我们讨论的是单键,我们讨论的是两个轨道,在核间轴中重叠。
Again we can look at this in terms of thinking about a picture this way, in terms of drawing the wave function out on an axis.
同样我们可以,用这个图像来考虑,从画轴上的波函数来考虑。
So you can see, if it's spinning on its own axis in this direction we'd call it spin up, where as this way it would be what we call spin down.
你们可以看到,如果它绕自己的轴朝这个方向转,我们就说它是自旋朝上,这个方向我们叫它自旋朝下。
On the vertical axis I'll put two vertical axes in, just for the sake of things on the vertical axis I'll put my expected payoffs.
坐标系的纵轴,由于种种原因,我花了两个纵轴,纵轴表示我的预期收益
What I want to do is I want to draw a picture here, in which on the horizontal axis, I'm going to put the probability of the other guy choosing Right.
我要在这里画一张图,坐标系的横轴,表示对手选右的概率
But in sigma orbitals, you have no nodal planes along the bond axis, so if we had a nodal plane here, we'd see an area where the wave function was equal to zero.
但在sigma轨道里,沿着轴向是没有节点平面的,如果我们有个节点,我们就会看到某个地方波函数等于0。
All right, so in terms of s p 3 hybrid orbitals, let's combine all four together on one axis, because this is what's going to happen in an s p 3 carbon atom.
对于sp3杂化轨道,让我们把4个结合起来,因为这是sp3碳原子中发生的情况。
So what we can say is look at each of these separately, so if we start with looking at the 2 p z orbital, the highest probability of finding an electron in the 2 p z orbital, is going to be along this z-axis.
我们可以来分别看看这些图,首先来看看2pz轨道,在2pz轨道里,找到电子的最大概率,是沿着z轴。
But keep in mind sigma orbitals have no nodal planes along the bond axis.
但记住sigma轨道沿着,键轴方向是没有节点的。
We said, "Let's take, for the simplest case that we can possibly imagine, namely a particle moving in one dimension along the x-axis with a constant acceleration a.
我们说过,"考虑我们可以想象的最简单的情况,即质点在一维空间运动,沿着 x 轴且保持恒定加速度 a
All right, so what we see here is we have our sigma bond that's along the internuclear axis here, but we also have a pi bond, because each of these atoms now has electrons in it's in a p orbital, so we're going to overlap of electron density above and below the bond.
这里我们看到sigma键,是沿着核间轴的,但我们还有一个π键,因为每个原子的p轨道上,都有电子,所以电子密度在键的上面,和下面都有电子密度交叠。
In this case, death from heart disease and what you see here, and I'll tell you what relative risk is in just a minute, but this is basically risk for disease over on this axis and here its weight.
在这幅图里是心脏病致死的,我会简短地介绍一下相对风险的定义,Y轴表示患病风险,X轴表示体重
The first one will be above and below the bond axis is where we'll see the electron density, and the second will be perpendicular to that, so it will be a density in front of and behind the bond axis.
第一个是在键轴之上和之下,我们可以看到电子密度,另外一个垂直于它,所以在键轴之前和之后有电子密度。
Any time two orbitals come straight on together in that internuclear axis, you're going to have a sigma bond.
任何时候两个轨道,在核间轴上直接到一起,你就能得到sigma键。
Essentially what we're seeing is overlapping in this z axis here.
本质上我们看到的是在z轴这里的交叠。
Let's create a graph here that on the x axis it's going to be time, so time zero will be when you first take in a food and then one hour later, two hours later will be shown as you go from left to right, and then we'll have blood glucose level up on the y axis.
我们在这建立一个曲线图,X轴代表的是时间,所以零时间点是你第一次进食的时间,然后一小时以后,两小时以后,是从左到右呈现在图表上的,在Y轴上是你的血糖值
