best frequency meaning in English
最佳频度
Examples
- The use of digital radio transmission and the advanced handover algorithms between radio cells in gsm networks allows for significantly better frequency usage than in analogue cellular systems , thus increasing the number of subscribers that can be served
Gsm网络使用数线传输和先进的无线越区切换算法，可以得到比模拟蜂窝系统好得多的频率利用，因而增加了服务的用户数。 - A building of high , the breadth , long comparison is very important . house for combination in an ideal of big set , reruns hour then contain the best frequency to respond to the width . frequency response range in other words , the combination can broadcast tallest to can also fully develop to the lowest frequency , and the equilibrium degree is as well high , and halt a circumstance is very tiny . the first glint wave primary reflection mutual interference for with wave secondary reflection of many glints the degree is not to result in confusion . combination that fundermental the diapason wave harmonics is again perfect
大套组合在一间理想的房子里，重播时便有最佳的频率响应宽度frequency response range 。换句话说，组合所能播放的最高至最低频率也可以尽情发挥，平衡度亦高，驻波情况极微。第一反射音波primary reflection和多次反射音波secondary reflection的互相干扰情度不至造成混乱。 - From the experimental results , we studied the relationship between the diameter of fiber , the composition of s s and the impacts upon the electromagnetic parameter of fibers . get following conclusions : both the complex permeability and the complex permittivity of ss fibers decreased with the increase of diameter in some region , the complex permittivity of 304 ss fibers , 2 m in diameter , could be up to 2 . 5 at the 2 ghz , the 302 ss fibers had better frequency dispersion properties than others , agreed with the requirements of the wide - band radar absorbing material in the range of 2ghz ~ 12ghz
西安建筑科技大学硕士学位论文讨论了影响不银矜冈纤维电磁参数的几个因素，实验结果出发研究了纤维直径、成分对纤维电磁参数的影响，得到以下结论:不钾练冈纤维的微波磁导率随纤维直径的减小而增大; 2微米的304不锈钢纤维的复数磁导率p ’ ‘在zgi ]吃处达到2 . 5 ; 302不韧矜冈纤维电磁胜能明显优于其它两种，且频谱特性在2 ~ 1zghz范围内符合对吸收剂频谱特性的要求。 - That is , in order to obtain a satisfied communication quality , in every group of beforehand setting channel , by means of link quality analysis ( lqa ) during two side ' s calling , answering and recognizing period , every channel will be arranged in prior order , the best communication channel can be found automatically , and the link can be set in the best frequency so as to raise the level anti - interference , and ensure our army ' s ability in fighting
即为了获得满意的通信质量，在预置的各组频道中，通过双方的呼叫、应答和确认过程，利用链路质量分析( lqa ) ，自动对电台所预置的若干个频率进行线路质量分析，将各频道按优先排队，从而自动找出当时最佳通信频道，并在最佳频率上建立链路，提高抗干扰能力，保障我军的指挥作战能力。 - The feedback of the output voltage is the major control loop . to achieve better frequency response and disturbance rejection of the input voltage , a input voltage feed - forward system is introduced in control loop . the duty - cycle of pwm applied at the gate of power mosfet is modulated by both input and output voltage
该芯片采用的控制方式为电压型pwm (脉冲宽度调制, pulsewidthmodulation )控制方式,以输出电压反馈作为主要控制参量,同时为了提高芯片对输入电压扰动的响应速度,采用了输入电压前馈方法,将输入电压因素引入了反馈控制环中,通过对输入输出电压的检测,控制加在功率mos管栅极电压上矩形脉冲的占空比,进而调节输出电压。
