In a caesium clock, the optimum frequency corresponds to 9,192,631,770 oscillations of the microwave per second (just over 9 GHz in frequency), so dividing the output electronically by this number provides one-second 'ticks' of the atomic clock.

对于铯原子钟，其最佳频率是微波每秒振动9，192，631，770次(频率略高于9 GHz)，而用电路把输出的信号除以这个数字就提供了原子钟的一声"滴答"。

This system has been applied to the stability measurement of the crystal oscillators and the rubidium clocks as well as the caesium clocks with zero dead time and non-offset frequency, and also to the calibration of the secondary frequency standard.

其测量精度目前约为2×10~(-12)τ~(-1)(0.1s≤τ≤1000s)，已应用于晶振、铷钟和铯钟的无间隙时间不偏调频率的稳定度测量以及次级频标的校频中。

Results showed that the Canonical Correlation Coefficient A(0.9486) was representing the direct correlation of the motorization with the injury and death rates, referring the higher the motorization, the greater the death and injury rates. The Canonical Correlation Coefficient B(0.9220) indicated the direct correlation between the highway capacity and the frequency of road injury, as well as the larger the highway capacity, the more frequency of road injury occurrance. The Canonical Correlation Coefficient C(0.6446) revealed the relations between levels of road situation and the accident rates per 10 000 vehicles.Results showed that the higher the quality of roadway, the lower was the accident rate.

结果显示，第一典则相关系数为0.9486，主要反映了城市机动化程度与车祸发生数、死亡率和受伤率之间的正相关性，即机动化程度越高，车祸发生数、死亡率和受伤率也越大；第二典则相关系数为0.9220，主要反映了客运量、货运量与车祸发生数之间的正相关性，即客运量和货运量越大，交通事故的发生次数越多；第三典则相关系数为0.6446，主要反映了道路质量与万车事故率之间的相关关系，道路质量好，则万车事故率低。

This can also be divided into two categories: one is to discuss the influence of power factor by way of dividing power circuit into capacitive and emotional under the circumstance of unchangeable voltage and frequency of output power, and the other is discussed the influence from voltage and frequency of power to power factor with the situation of constant component parameters.

具体又分为两种情况：一种是在电源的输出电压和频率都不变的条件下，把电路分为容性和感性，讨论了元件参数对功率因数的影响，另一种是讨论了在元件参数不变的条件下，电源的频率和电压对功率因数的影响。

Capacitive coupling favors transfer of higher frequency components, whereas inductive coupling favors transfer of lower frequency components.

电容耦合是用于高频元件的能量传输，而电感耦合应用于低频元件能量传输。

The dependence of resistance on the curing temperature illustrated that-codoped BST was capable of exhibiting the positive temperature coefficient effect at low frequency; nevertheless,it might display the negative temperature coefficient effect at other frequencies. The relationships between the resistance and applied voltage revealed that the resistance property of-codoped BST appeared at low frequencies, but its property of capacitive reactance might present at high frequency.

阻温特性曲线显示，在低频时它显示正温度系数效应，在其它频率则显示负温度系数效应电阻与电压关系显示，低频时它呈现电阻特性，而高频时则显示容抗特性。

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。

Carrier wave and modulating wave with high frequency were used to control the exciting current and frequency respectively.

可用于波流共存场多向随机波浪传播变形的模拟和预报。9。利用载波和高频调幅波分别控制励磁电流(0~15 A)和励磁频率(50~1000 Hz)的大小。
