衰减

The pressure attenuation of stress wave and the effect of blasting load on ground concrete structure in soil and rock blasting were investigated using LS_DYNA procedure in the aspect of mechanical properties of soil and rock, location of the goal and the explosives, as well as the rarefaction waves of air etc.

利用LS_DYNA程序，从岩土本身的力学性能、目标与炸药的位置、空气稀疏波的影响等多个角度出发，研究了岩土爆破中应力波的压力衰减以及爆破对地表混凝土结构物的影响，得到了其中的规律，为建筑结构的防护提供了一些思路与依据。

This figure is typically much higher than the decay rate of a regulated power supply that has lost power.

这个公式显然比可调电源的衰减率更高。

In addition, the decay rate of early sound energy varies with receiver positions.

同时，早期反射声能在不同位置上的衰减也不均匀，表现在EDT的偏差较RT的大。

In addition, scientists make the assumption that the element's rate of decay has not changed since that time.

此外，科学家提出假设单元的衰减率并未改变自那时起。

In chapter 3, the angular distributions of SpE decay rate of a two-level atom placed in the multi-layered structure is investigated.

论文的第三章主要研究了由一维多层结构构成的微腔中二能级原子自发衰减的角分布。

At this maximal rate of hate decay, the time taken for the warrior's threat to decay to 90% of the original value would be 26.5 hours.

在这种极端的衰减速度下，战士的threat要降到最初值的90%需要花费26.5小时。

The variant rate of decay rate is zero within thhe accuracy errors.

在精确的实验误差范围内，衰减速率的变化率为零。

Now, on the other hand, we're being told, in effect, Sure everything changed, but not radioactive bombardment and its rate of decay -- they have remained at the same level for billions of years.

"现在，在另一方面，我们被告知，实际上是"相信一切变了，但没有放射性轰击及其衰减率--他们都保持在同一水平，为十亿年。

The rate of decay of this frequency is a function of the RPH * CPH time constant.

在此点火斜坡模式下，输出频率指数衰减到最低值。

By means of state variables transformation, the problem of guaranteed cost reliable control with constraint of decay rate is reduced to an equivalent problem of guaranteed cost reliable control.

经过适当的状态变换，将原系统的指定衰减度保代价可靠控制问题转化为另一个等价系统的保代价可靠控制问题。

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％。
