文章还提出了多种矢量水听器指向性锐化的方法，通过这些方法在低频形成恒定束宽窄指向性。

By reason of the dipole directivity of particle velocity sensor and also the acoustic intensity averagor, and its being able to realize the electronic rotation, coherent interferences can be effectively suppressed by skillful use of its zero point and extremal point.

对于四输出分量的矢量传感器来说，声压和振速加权处理在各向同性噪声场中可以获得4.8dB的空间指向性增益，最优加权处理可以获得6dB的空间指向性增益。

3Effective history principle gives the chance for the translators of the different ages to retranslate the same source, from which three re-translation strategy are standardized: corrective retranslation strategy; reconstruction retranslation strategy; proselytizing retranslation strategy. Gadamer also puts forward a non-translatable hermeneutics principle. But this does.not mean his negation to translation. The model of conversation in understanding proposed by Gadamer points out that translation is not the monologue of the translator but a process of dialogues between translator and source which leads to mutual understanding.

效果历史原则既赋予了不同历史时代的译者重译同一文本的机会，并由此可以规范出三种重译策略：勘误性重译策略、重构性重译策略和指向性重译策略，也提出了不可翻译性这一诠释学原理，但这并不代表伽达默尔对翻译的否定，他所提出的理解的对话模式说明翻译的过程并非原作者的个人独白，而是译者与文本进行对话并达到相互理解的过程，这反而在理论上论证了译者劳动的创造性价值，肯定了翻译创造论。

The theoretical curve of the sound directivity which is influenced by the laser beam radius is drawn by the numerical method and drawing software.

讨论了激光束半径对声源指向性的影响，并用数值计算方法和绘图软件，画出激光束半径对声源指向性影响的理论曲线图。

In addition, the evaluation of the local orientation and image gradients is essentially equivalent.

由于局部指向性的计算在本质上是图像梯度的计算，因此采用几种不同的梯度算子来计算局部指向性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
