It also can realize asynchronous serial communications with the computer which connects with it to make up network to show the computer and network's advantageous lightly and improve its intelegence.

ADE7755引脚F1和F2一较低频率形式输出有功功率平均值，能直接驱动机电式计度器。引脚CF以较高频率形式输出有功功率的瞬时值，用于校验。

It was indicated that the effect of crystal orientation on interfacial stability is because of the different atomic bond number formed in the solidification of liquid atoms on different crystal planes, which affects the decrease of system energy, and affects the effective jump frequency of liquid atom migration to solid interface and solid atom migration to liquid, and finally affects the solute distribution in the front of liquid-solid interface and composition undercooling.

研究表明，晶体取向对凝固界面稳定性的影响是由于液相原子在不同晶面结晶面上沉积时形成的原子键不同，影响了系统自由能的降低，影响了液相原子迁移至固相界面上的有效跳动频率和固相原子迁移至液相中的有效跳动频率，影响了液固相界面前沿的溶质分布和成分过冷所致。

A large uumber of numerical calculations using the analytic formula and the dispersion equation have been candied out on the relations of the attenuation and phase constant with wave frequency, thickness and conductivity of the lossy layer.

此式适用于截止频率附近，通过解析表达式和波导模式色散方程，对衰减常数和相位常数进行了大量数值计算，得到了它们随损耗层厚度、频率以及损耗层电导率的变化规律，两种方法所获得的结果有较好的一致性，研究表明，损耗强度和损耗层厚度的变化会改变波导中电磁模式的色散和简并特性，对于改善高功率回旋行波放大器中注波互作用带宽和模式竞争非常有益。

In this, and in the several other views, the line array loudspeaker may radiate over the full audible frequency range, or may radiate over a limited frequency range, typically the high audible frequencies.

在该视图和另外几个视图中，线性阵列扬声器可以辐射整个可听频率范围或可以辐射有限频率范围，通常为可听高频。

The waves cause the tip to vibrate, and when the frequency of the incoming wave matches the resonance frequency of the tube, the device can convert the transmission into an audible signal.

电波引起末端振动，当接收的电波频率与管共振频率相配，该装置就能把波形转换成音频信号。

This eliminates the problem of S/N ratio degrading as the modulating frequency rises, but now results in a rolling off of the audio response if a "flat" FM signal is received.

这消除了随解制频率增大而下降的S/N比，但是造成音频频率响应的下降，当收到一个"平"的FM信号时。

The high frequencies which was more than 8 kHz was not the routine test range for the pure-tone audiometry.

临床常用的听力评价方法为纯音听力计测试，其测试的频率为0.125～8 kHz，8 kHz以上的各高频频率为非常规纯音测听测试范围。

It locks the frequency of the carrier-wave at 35MHz.The stabilization of the carrier-wave can be 4×10-5,the accuracy can be 3×10-5.The frequency modulation and the confection of the carrier-wave are realized by the capacity-changing diode V149 and the integration voltage-control oscillator MC1648 chip.The end power amplifier uses the audion 2SC1970 to make it work in the third magnifying state,it improves the efficiency of the magnifier and the power of the output reaches the design demand.
