After vibratory load actings, the cohesive strength index and internal friction angle of the sample are decreased by 51.72% and 50% respectively; and the shear strength curve shifts down obviously under same testing conditions.

研究结果显示，在其他试验条件相同的情况下，经振动荷载作用后的红黏土试样黏聚力降低51.72%，内摩擦角减少50%，抗剪强度线向下显著偏移，表明振动荷载不利于红黏土的稳定和承载。

So, in the present study, we have investigated the photodissociation of these alkyl bromides at their A-band using resonance-enhanced multiphoton ionization scheme, ion velocity map imaging technique, expecting to get a variety of information.

同时，采用单色双光子质量分辨的零动能光谱技术得到了溴乙烷的高分辨的离子振动光谱，并分析了离子振动光谱与解离中间态的关系。

We also have those who were rising in parallel in our kingdom that have been rolled back in recent months to prevent them from combusting and causing earth further global problems.

我们王国中也有一些正同样升高振动的成员，在最近几个月内已被退回振动，以去阻止他们自燃且导致地球进一步的全球性问题。

Coordinating among these parameters is crucial but the basic element of the evaluation is still the operation weight of compactors, which represents an equivalent pressure of the vibratory drum. For the two kinds of single drum vibratory compactors, fully hydraulic drive and mechanical drive, compacting capability of the former is certainly higher than that of the later.

这些参数的相互协调至关重要，但其评价的最基本要素仍然是压路机的工作重量，并且集中体现在振动轮的&当量压力&，对于两种类型的单轮振动压路机，当然是全液压机型的压实能力远远大于机械传动机型。

Selecting seven mechanical and seven fully hydraulic drive respectively in two series 10~20t single drum vibratory compactors from the same manufacturer, calculation and evaluation on main techno-economical performance parameters of mechanically driven single drum vibratory compactors are conducted with value engineering.

选取同一制造商生产的机械传动型和全液压型两系列的10-22t各7个规格的单轮振动压路机产品，运用价值工程原理，对机械传动型单轮振动压路机进行主要技术经济性能参数的计算和评价。

We note from the further studies that in the crystals, which sharing the similar crystal structures and coordinational environments, the magnitude of the Stokes shift of the luminescence of the dopant ion is in line with the average covalency of the replaced lattice site. This is because that the nature of Stokes shift is the energy transfer from the luminescent ion to the host lattice. The value of this energy is determined by the frequency of the host lattice in which the frequency is controlled by the chemical bond characters.

更深入的研究发现，在晶体结构和中心离子配位环境非常相似的系列晶体中，掺杂离子发射光的Stokes位移值与其所取代格位的平均共价性成正比的关系，这是由于Stokes位移的本质是发光离子在发光过程中向基质以光波辐射的形式传递能量，这一能量的大小是由基质的振动频率决定的，而基质的化学键性质恰恰决定着基质的振动频率。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
