stabilized frequency

It has been tested that frequency stability of instrument developed reaches 1.74 × 10-9, temperature of laser tube is around 430C when frequency is stabilized, which achieves the anticipation.

仪器完成了设计、装调、运行任务，并对其频率稳定度进行了实测，频率稳定度指标为1.74×10-9，稳频时激光管温度在430C左右，达到了预期目标。

Through using hydraulic proportion valve to control the double-roller moveable device, the ability of refine area is improved and movement frequency of 350t cool-shear is stabilized. It can solve the problem of rolling ability exceed to treatment ability of refine area.

通过采用液压比例阀控制双辊道移钢装置，提高精整区能力，稳定350t冷摆剪运行节奏，解决轧制能力大于精整处理能力的问题。

Measurement of Frequency Stability of Passive Frequency Stabilized CO_2 Laser

被动式稳频CO2激光器频率稳定度的测量

Based on the analysis, a frequency and phase stabilized two-phase sinusoidal power clock generator is proposed, which, while connected to an external reference clock, makes the oscillating circuit in synchronization with the reference clock.

在此基础上，提出了稳定功率时钟频率与相位的功率时钟产生电路，即接入外部参考时钟，使振荡电路与参考时钟同步。

Comparing with the iodine absorbing stabilized frequency standard laser national standard by the method of beat frequency, we found the frequency stability of this laser is 1 × 10-9 and it can work continuously over eight hours.

与国家计量测试研究院的碘吸收稳频标准激光器拍频，频率稳定度为1×10~（-9）。
