指向性

The microphone has an excellent cardioid pickup pattern, making it perfect for vocal applications.

一流的麦克风，有心型指向性，完全适合唱歌使用。

The frequency response of the cardioid and figure-8 directional characteristics are very flat for frontal sound incidence, even in the upper frequency range.

主要是说，这mic的膜片位于前端并有logo标示，心形和8字指向性的频响曲线在高频处也十分平坦，在近距离拾音时不会使声音尖锐。

Shure Wired Microphone EZG18SE Specifications: Frequency Response: 50 to 17,000 Hz Polar Pattern: Cardioid Output Impedance (at 1 kHz): Rated at 150 ?

舒尔有线麦克风EZG18SE技术指标：频率响应：50至17，000 Hz指向性：心输出阻抗（1千赫）：150额定？

The Phanthera V impresses with the same qualities as its cardioid only counterpart, bringing along a lively and intense sound quality and highlighting the sonic aspects of the source material in a subtle manner.

Phanthera V 的心型指向性给人以深刻的印象。长久发展以来，一个真实的声音和一个精致的外观在某种意义上讲是很难做到完美的。

In this paper, a closed chamber technique for measuring the complex free field sensitivity and directivity patterns of line array is described.

本文提出了一种在密闭管中测量线阵的自由场复数灵敏度和指向性图的方法。

Among them 3 kinds of pattern are more familiar, it is mode of forum public relations, the small number of people gives out gigantic voice through occupying the platform such as forum, BBS by force, flooded popular true sound; 2 it is the network shoves a hand, prove through plan and lack but the operation with apparent directivity, the purpose; that achieves attack competitor or information to distribute searchs engine the 3rd kind namely, the search engine that holds market dominant position often screen inimical or the website that does not pay, put the content that with oneself interest positive closes in search result front row, one when intervene the practice that searchs a result made industry goes regular.

其中三种模式比较常见，一是论坛公关模式，少数人通过霸占论坛、BBS等平台发出巨大的声音，淹没了大众的真正声音；二是网络推手，通过策划以及缺乏论证但是指向性明显的操作，达到攻击竞争对手或信息散布的目的；第三种就是搜索引擎，占据市场优势的搜索引擎往往屏蔽不友善或不付钱的网站，并将与自己利益正相关的内容放在搜索结果前列，干预搜索结果的做法成为了业界的一条潜规则。

It has many virtues, such as small bulk, high sensitivity and direction of dipole source.

矢量传感器是一种新颖的水声传感器，它具有体积小、灵敏度高、具有偶极子指向性等优越性。

Then they discovered that the directivity of the magnet.

后来又发现了磁石的指向性。

This dissertation presents the research and applications of microstrip coupler with high directivity.

本论文主要在研究高指向性微带结构及其应用。

In this system, the different characteristic and directivity of the different frequencies audio signals while propagating in the air are tested and analyzed.

利用该系统对不同频率声频信号在传输过程中的变化特征及其指向性进行了实验研究和对比分析。

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。
