破坏性

The interferential effect among antennas is the researching key point. It causes not only signal process at baseband difficult but also destructive interference to radiation pattern. The interferential effect is discussed in the measured results.

天线间信号干扰的效应就是研究的重点，除了造成基频信号处理的困难外，也会造成天线间的破坏性干涉使得增益降低，量测的结果会说明信号干扰效应造成的问题，量测结果和心得会讨论。

In some materials with periodic variation of dielectric constants and light within a certain frequency range shows exponential decay due to destructive interference and cannot propagate. This phenomenon is called photonic bandgap and this kind of structures is called photonic crystals.

介电系数周期性排列的材料，部分波段会因破坏性干涉呈指数衰减，导致无法在此结构上传播，此现象称为光子能隙，此类具有介电系数周期性排列的结构则称为光子晶体。

Between 1/4 and 1/2-wavelength spacing the pattern narrows, but side lobes (interferencepatterns, caused by destructive interference) do not appear until the spacing is greater than 1/2 wavelength.

在1/4波长和1/2波长之间是不会出现旁瓣（副极大值，干涉波形，通常是由破坏性的干涉导致）的，这一现象会持续直到间距大於1/2波长。

Most DDL operations, except for those listed in the section " Share DDL Locks ", require exclusive DDL locks for a resource to prevent destructive interference with other DDL operations that might modify or reference the same schema object.

除了在"共享 DDL 锁"一节列出的操作外，大部分 DDL 操作都需要获得相关资源上的排他 DDL 锁，从而防止其他可能修改或引用相同方案对象的 DDL 操作带来的破坏性的冲突。

The shaped pulses were shown to be phase-sensitive atintensities too low to access different higher electronic states,and so these pulses apparently steer the isomerization throughconstructive and destructive interference effects, a mechanismsupported by observed signatures of vibrational coherence.

变过形的脉冲在低强度下显得很敏感，这种强度很小，因此很难进入更高的电子状态。于是，很明显地，这些脉冲能给通过破坏性和建设性的干扰效应来操控异构化作用。观测到的振动一致信号更支持了这样一种机制。

To write data back into memory immediately after a destructive readout.

在经过破坏性读出之后，立即将数据重新写入存储器的操作。

When you do this, you will find that the failure can be more destructive than you ever thought possible.

当您这样做时，你会发现失败具有更大的破坏性比你的想象。

Such disappointment, however, is not only unjust, it is also destructive.

这样的失望，但是，不仅是不公正的，也是破坏性的。

And therefore they are really very destructive people.

所以他们是真正非常具有破坏性的人们。

If you smoke ,i hope you will try your best to give up this destructive habit.

如果你现在还吸烟，我希望你尽自己的能力尝试去放弃这个具有破坏性的习惯。

Do you know, i need you to come back

你知道吗，我需要你回来
