directivity

The directivity fibers on the surface, could prevent run down of the suspended solid.

The poor design of the enclosures could cause the irregularity in frequency responses and directivity patterns.

By the nonlinearity of the propagation medium-air, the audible sound with high directivity can be produced.

A dual ayer array of strip rectangular dipoles structure is investigated, leading to a directivity bandwidth enhancement.

To improve the directivity and gain, the four units of plate end-fire antennas are arranged in the direction of end-fire.

If have no a definite train of thought have no a directivity can follow deeply , so get turn over and lose.

Meanwhile, there was obvious directivity of topographic effects.

Compared to microwave, millimeter-wave has good directivity, Its detecting and imaging system can have higher resolution.

Coordinate transformation approach is introduced to manipulate the directivity of antennas.

Compared to microwave, millimeter-wave has good directivity, strong anti-jamming ability, and can penetrate plasma etc.

The directivity of emitter by changing the number and relative location of ultrasonic transducers are simulated.

The article studies a method of raising directional precision by amplitude shading in sensor arrays directivity design.

moreover , taking on the rayleigh integral the far field acoustic pressure and the directivity formula is obtained.

At the same value of frequency and size, the directivity of quadrate ring piston is sharper than that of quadrate piston.

Dispersion Angle vs Frequency This graph displays the MR64B's excellent horizontal and vertical directivity control.

Then they discovered that the directivity of the magnet.

the directivity , sensitivity and gain of the extended hydrophone are researched based on the model.

The antenna received signals with no directivity.

DENG Xiao-ping higher education thought has strategic, characteristic and so on directivity, openness and national characteristic.

In the long period range, the spectral acceleration of motions with fling step is generally larger than that with forward directivity.

The oil seal has the directivity, cannot install instead.

Comparing to other ranging method, the laser ranging has better directivity and the higher range precision, and it can ranges further.

At the same time, it has good parameters of wide band, good directivity and stable phase center and so on.

The good "8" cosine vector directivity and frequency response curves are obtained, and the sensor's sensitivity reaches -184. 6dB at 1 KHz.
