衰减的

Chapter 2 proposes the concept of attenuation ellipsoid.

在第2章首先利用散射参数提出衰减椭球的概念，并讨论其性质。

These are discussed in terms of the edge states and the evanescent modes.

我们也会讨论边缘态跟衰减态的现象。

However, we also show that a similar construction does notlead to exponential decay.

进一步，我们将说明类似的构造方法不可能得到指数衰减。

You may recognise this as an exponential decay graph.

你可以看出这是一个指数的衰减图。

It is easy to show, for an exponential decay, that the uncertainty in the life time is also z

很容易证明，对于指数衰减来说，寿命的不确定性也是z。

Note the exponential decay in the current using both a positive and a negative test voltage.

注意在使用正、负测试电压时电流的指数衰减情况。

Finally,we characterize the exponential decay of the vorticity, too.

最后，同样也刻画了旋度随时间发展的指数衰减性。

In computer simulations, an exponential decay function is used for the tissue residue function.

电脑模拟时，指数衰减函数用来描述组织的残余函数模型。

The electron number density does not strictly obey exponential damping law in a long period.

电子数密度在很长的一段时间内不遵循指数衰减规律。

This ensures that the impulse response will decay exponentially with time.

这将确保系统的脉冲响应将随时间指数衰减。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
