time base frequency

At the same time, dynamical analysis for a given bridge has been done through the software MIDAS, and the relation of between basic frequency and sag ratio of stress-ribbon footbridges and frequency wave on the base of given sag have been educed.

同时，通过计算软件MIDAS对拟定桥梁进行动力分析，得出人行悬带桥的基频与垂跨比的关系以及特定垂度下的频率波形。

Chapter 3 discusses the time base and frequency base, as well as the measure methods of time and frequency.

第三章和第四章对双基地雷达系统中关键技术之一的时间、频率同步的相关技术问题进行了分析和研究。

The base and emitter transit time increase and the cutoff frequency decreases at low temperature due to the trapping effect of shallow energy level impurities.

而由于浅能级杂质的陷阱效应，低温下基区和发射区渡越时间变长，截止频率下降。

In this paper, a firm joint between steel base and diamond grain was realized by using a high frequency induction welding technique. Ni Cr was used as the brazing alloy and the brazing current and time were carefully controlled.

利用高频感应加热的方法，以Ni-Cr合金为钎料，通过控制电流和加热时间，实现了金刚石与钢基体的牢固连接。

A new tool that can test the clock base frequency error of energy measuring devices and provide GPS standard time to calibrate real-time clock was introduced in this paper.

介绍了一种用来测量电能计量装置的时钟基频误差，并提供GPS标准时间以校准其实时时钟的新型工具。
