在传统的对流混合程理论的基础上，借助于湍流的现象中雷诺数与不稳定性、湍流与涡旋等物理量的类比考虑，我们提出了一种描述湍流能谱的改进形式，认为对流区湍流能谱能够分离成时间和空间两部分。

Some DDL operations require share DDL locks for a resource to prevent destructive interference with conflicting DDL operations, but allow data concurrency for similar DDL operations.

某些 DDL 操作需要获取相关资源上的共享 DDL 锁以防止与之冲突的 DDL 操作造成破坏性的干扰，但与之类似的 DDL 操作可以并发地访问数据，不受共享 DDL 锁的限制。

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。

All locks acquired by statements within a transaction are held for the duration of the transaction, preventing destructive interference including dirty reads, lost updates , and destructive DDL operations from concurrent transactions.

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。
