The main clue of the paper is that in view of the danger and rapidness, taking practicable signal processing technology, sending torpedo information to acoustic countermeasure system rapidly and accurately.

本文研究工作的主线是针对鱼雷攻击的危险性和快速性，采取切实可行的信号处理方法，快速准确地向水面舰艇水声对抗系统提供鱼雷报警信息。

The numerical results show that LQR could control the power flow transmission at the natural frequencies of the coupled system, but increase power transmission at the antiresonance frequencies. The position of the sensors in feedback control is important to the effect of the active isolation and the closedloop's stability.

研究结果表明：线性二次调节器可有效地控制系统共振时振动能量向基础的传递，但增加了系统反共振区域功率流的传递；在输出反馈控制中，从系统稳定性和可实现性上考虑，传感器应布置于隔振器与机器的连接点处。

To our knowledge, the electric field effect on the optical pattern formation phenomena has not been included in the earlier theoretical analysis.

在外加电场偏压下的线状液晶样品，由於其本身的介电非等向性，液晶分子的排列可以利用外加电场加以适当地控制。

These DSs were first observed at 9 weeks in the distal part of ascending fibers that consist of gracile fasciculus and cerebellospinal-gracile nucleus and white matter of cerebellum. They extend along medulla oblongate to medulla cervix、medulla thorax、medulla lumbalis in accordance with dying-back type degeneration. The corticospinal tract were affected at 18 weeks,and thalamus、the olfactory pathway、the visal pathway、the auditory pathway were affected at 32 weeks.

这种DS从9周龄开始，首先在构成薄束路和脊髓小脑后路的上行纤维的远端区域-薄束核区和小脑白质出现，逐渐按照延髓、颈髓、胸髓、腰髓的顺序，向细胞体方向逆行性地进展。18周龄时波及到锥体路，32周龄时进一步波及到丘脑和嗅觉、视觉、听觉传导路。

But mathematical science, which is the only real science that the entire civilized world has agreed upon, furnishes unmistakable proof of history repeating itself and shows that the cycle theory, or har monic analysis, is the only thing that we can rely upon to ascertain the future.

但是数学，整个文明世界承认的科学已明白无误地证明了历史的再现性，并向我们展示了循环理论，或类比分析，它是我们发现未来的唯一方法。

The ray theory of geometric optics was applied to visually investigate the propagation of quasi stationary waves in time mean basic flow and interpret the zonal nonhomogeneity.

应用几何光学中的射线理论，直观地讨论了准定常波在时间平均基流中的传播，解释了定常波传播的纬向非均匀性。

It put up no immobile shape ,have relative flowability , can intrude into the deep formation,selectively plug big pore pathor and high permeability formation,make the fluid turn to low permeability formation ,improve the low conformance factor caused by the nonhomogeneity ,improve the recovery ratio in big range .

它表现出没有一定形状，具有一定流动性，能进入地层深部，选择性地堵塞大孔道或高渗透层，使液流转向进入较低渗透层，改善因非均质性造成的波及系数低的问题，从而大幅度的提高油藏的采收率。

A special process named " silicification followed by carbonization" was adopted to solve the problems such as SiC grains forming on the SiO_.

通过"先硅化再碳化"的工艺方法可以较好地解决S iO2/S i复合衬底上S iC成核困难以及粘附性差的问题，同时还可以有效抑制S iO2中的O原子向S iC生长膜扩散。

A special process named "silicification followed by carbonization" was adopted to solve the problems such as SiC grains forming on the SiO2 and poor cohesiveness between the SiC and substrate. Furthermore,this method is effective to prevent O atoms diffusing from SiO2 into SiC epilayer.

通过"先硅化再碳化"的工艺方法可以较好地解决SiO2/Si复合衬底上SiC成核困难以及粘附性差的问题，同时还可以有效抑制SiO2中的O原子向SiC生长膜扩散。

Within the divine order, we each have our own special calling. Listen to yours and follow it faithfully.

在神圣的自然法则底下，我们每个人都有各自特别的性向，聆听你自己的并且忠实地追随。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
