查询词典 proper frequency

It was shown that the SNR of the RADS could be improved by using a microwave cavity with proper microwave field mode and high microwave filling factor, a rubidium spectrum lamp with high spectrum purity and a separated isotope filtering scheme in the physics package design. The performance of the rubidium atomic frequency standard could be improved by taking all these factors into consideration.

本文分析了微波腔的结构、铷光谱灯的光谱纯度和同位素滤光方案对信噪比的影响，指出采用模式优越、微波填充因子大的微波腔，光谱纯度高的铷光谱灯，用分离滤光方法进行同位素滤光，可以提高铷原子鉴频信号的信噪比，从而使铷频标的稳定度指标得到进一步改善。

Definite switching sequence are the principal means for limiting service frequency overvoltages, that the application of proper circuit breakers are effective and economical means to limit switching surg...

文章根据我国的运行经验指出，采用现行结构的绝缘子时，绝缘水平的确定，洩漏比距所起的控制作用以及变电所的外绝缘，也应当满足同样要求。

At first,the performance of different discriminators in code and carrier loop are compared based on anlyzing the principle of GPS tracking.Then the tracking effects with different loop patameters are simulated and compared.At last,a couple of discriminators are selected and proper loop parameters are designed to track actual GPS intermediate frequency signal,and the tracking results validate the design.

在分析GPS跟踪原理的基础上，对比码环与载波环不同鉴相器的性能，然后在不同环路参数下对跟踪效果进行了仿真比较，最后选择一组鉴相器并设计合适的环路参数，对实际采集的GPS中频信号进行跟踪，跟踪结果验证了设计环路的有效性。

Although DDR3 supposes to reduce the system power consumption with its lower supply voltage of 1.5V versus 1.8V required on common DDR2, but since it is clocking at extremely high frequency, there is a need to have proper power management system and that is how the company's proprietary DHX+(Dual-path Heat eXchange) heatsink comes into picture.

虽然DDR3内存假设，以减少系统功耗较低的电源电压为枚1.5V与1.8V的需要共同的DDR2 ，但因为它是在非常高的时钟频率，还需要有适当的电源管理系统，这是如何公司专有的DHX +散热器进入图片。

Crossover network divide frequencies out to each specific loudspeaker component,proper phasing and precision frequency rolloff allow each loudspeaker to perform at it best.

独特的聚炳烯低音盆配抗紫外线丁基橡胶复合折环，提供持久稳定的弹性刚力，保证各种恶劣环境下音盆稳定的线性位移，赋予音盆极为优异的频率响应。
