指向性

The establishment question situation, can spiritedly cause the classroom, the knowledge simple to be easy to understand, its intense practice directivity is extremely obvious.

创设问题的情境，能使课堂生动活泼、知识浅显易懂，其强烈的实践指向性是极其明显的。

The result of experiment proves that the matching layer transducer can use in arrays in effect, its directive parameter is not unconventionality change, and its power function is all right.

实验证明匹配层换能器能够有效的进行布阵，布阵后的指向性参数没有异常变化，功率线性良好等。

They are numb and vapid, scattered bodies and disorderly visions lacking any clear referent, devoid of identity and self-recognition, unnameable in any circumstance.

照片上的形象似乎变成了一种寄生物，她们麻木而乏味，松散的身形和凌乱的目光缺乏任何意义的指向性，甚至缺乏身份的自我认同，在任何层次上都无法被命名。

A kind of acoustic phased arc array with circumferentially controlled directivity presented in this paper can be used to make acoustic logging with circumferential azimuth detection function.

为了实现声波测井的周向分辨能力，提出了可应用于声波测井的、具有周向辐射指向性的相控圆弧阵声波辐射器方案。

You are asking me, I think, about the meaning of life, though you have posed y our question in code — in terms of the observable and measurable phenomenon o f senior career choice rather than the abstract, unfathomable and almost embar rassing realm of metaphysics.

我认为，你们问我生活的意义的时候，是带着指向性的——你们把它看成是高级职业选择中可见、可量度的现象，而不是一种抽象而深不可测的、形而上学的尴尬境地。

Because the modernize evolvement of metropolis area depends on its traffic modes, on the one side, urban development and renewal are conspicuously oriented by the subway system with a progress along an axis. On the other side, the underground space in central district became an act of conglomerating.

一方面，现代城市演变很大程度取决于交通方式，地铁轨道交通对于城市发展与更新有明显的指向性，沿轴产生以整体进步为导向的发展趋势；另一方面中心区地下空间的大规模开发促进城市局部高强度开发，呈团块状发展。

The measurement system （called associated with a slowly rotating microphone RRS） is composed of a repeatedly inspirited sound source and the measured result is equivalent to that of using a round microphone array in room acoustics measurement.

室内声学测量中，在声源重复发射声信号的同时，将单个无指向性传声器缓慢而匀速地转动，其测量结果等效于以转盘转轴为中心的圆形传声器阵列，相应的测量系统简称为RRS。

The second part presents a solution for miniaturizing microstrip loose coupler with high directivity.

在论文的第二部份，提出了一种设计架构，能有效缩小微带平行弱耦合器的面积，并保有高指向性的效能。

The U 87 Ai condenser microphone is a large diaphragm microphone with three polar patterns and a unique frequency and transient response characteristic.

这个电容mic有着大膜片和三种独立指向性和单一频率还有良好的瞬态响应的特点。

A number of birders have asked us if RememBird can be used with their existing directional microphones.

相当数量的鸟友问过我们RememBird 能否使用他们自己已有的指向性麦克风。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
