高频率的

Stand newly because of, searching engine won't know you commonly, refer, update an article then namely next, deliver oneself website address to a few newer frequency to compare tall place, on the station that searchs engine to just climb you likely so, and to Google collect very helpful also, yantai Seo station is collected one day by Google profit from I wrote a soft article in stationmaster net, the newer frequency of stationmaster net is very tall, the flexible language that I release is similar two hours in can searching engine, found, at the same time this also is outside catenary, google search index props up the catenary outside liking very much, if you can be in short-term inside produce a high quality outside catenary, submit the word below again next, general Google can collect your station very quickly.

因为一个新站，搜索引擎一般是不会知道你的，提交完，然后就是接着更新文章，把自己的网站地址发到一些更新频率比较高的地方，这样搜索引擎才有可能爬到你的站上，而且对google的收录也非常有帮助，烟台seo站一天就被google收录得益于我在站长网写了一篇软文，站长网的更新频率很高，我发布的软文差不多两个小时吧就可以在搜索引擎中找到了，同时这也算是个外链吧，google搜索引擎很喜欢外链，假如你能在短期内搞到个高质量的外链，然后再提交下的话，一般google很快就能收录你的站了。

The result show the resolution of temperature measured by dither frequency is very high.

由于测量抖动频率的精度较高，故由抖动频率测量温度具有很高的分辨率。

Where the irrigating frequency was 1 or more than 1 every four days, it did not remarkably affect the ET of potato; but where the irrigating frequency was 1 every six days or 1 every eight days, the ET of potato measured by a lysimeter was obviously higher than what it was in the treatment with a higher irrigating frequency.

大于或等于1次/4 d滴灌灌水频率对马铃薯的腾发量影响不明显；但当滴灌灌水频率为1次/6 d或1次/8 d时，由蒸渗仪测得的马铃薯腾发量明显低于更高频率处理。

In this paper, an algorithm to achieve both two dimensional high resolution and wide swath is proposed. Every small satellite work in the active state, they transmit and receive different frequency band signal simultaneity. First, the azimuth ambiguity is eliminated in each frequency sub-band, then the signal is rectified to zero Doppler frequency, after that this algorithm does the range spectral synthesis to achieve high range resolution.

该文分析了一种沿航向排列分布式小卫星宽测绘带二维高分辨率成像技术，每颗卫星同时发射接收不同频率的线性调频信号，先分别在每个子带解方位多普勒模糊，并将方位多普勒中心频率调整至零频，然后在距离向进行子带拼接得到大带宽的线性调频信号从而得到高的距离向分辨率。

The agglomerations sizes of fine particles in the fluidized bed are smaller under higher SPL. The sound waves have little effect on the agglomerations when it is under 120dB. But the agglomerations sizes will be dramatically reduced to 180μm from 720μm when the SPL is above 130dB. The umf has a minimum value at an appropriate frequency of sound and a good quality of fluidization can exist in a greater ranges of frequency of sound when the SPL is higher.

当频率高于120Hz，流化床中形成聚团尺寸随着频率的增加而增大，最小流化速度也随着频率的增加而增大，当频率低于120Hz，流化床中形成聚团尺寸随着频率的减小而增大，最小流化速度也随着频率的减小而增大；料层越高，声波的衰减越大，超细颗粒的流化效果越差，最小流化速度越大。

The results described above demonstrated that physiological AAI pacing increased CO remarkedly by preserving original LVEF and SV, while nonphysiological VVI pacing and physiological DDD pacing restricted the increase in CO as a result of reduced LVEF and SV.

其血流动力学效果表现为，生理性AAI起搏能在保持原有LVEF和较高SV较高的基础上，随起搏频率的增快，CO呈线性增加，而VVI和DDD起搏则由于LVEF、SV随频率增加而有所降低，致使CO增加受到限制。

After the cut-off frequency has been determined, the active noise-filtered system can be designed with several circuits to filter out those frequencies higher than the cut-off frequency and reserve the speech voice only. Besides, the music signals from the MP3 or a CD player can also be transmitted to the earplug system for increasing the signal noise ratio. The anxiety and tension of patients during treatments can, thus, be relaxed due to the euphonious music and toothaches of the patient might be further reduced.

本研究首先以离线的方式收集各类牙科噪音，然后将它传递到个人电脑，并使用CoolEdit及LabVIEW软体程式，分析出在牙科治疗过程中所产生之噪音的频率范围，最后透过各种比较，找出适当的截止频率，在截止频率(1KHz)被决定之后；针对该截止频率，使用主动式滤波的方式设计出相关的电路，组成主动式噪音率除系统，来滤除那些高於截止频率的噪音信号，只保留语音频率范围；此外透过mp3或cd player所播放出的音乐讯号，也可以同时被传递到耳塞系统来增加信号杂讯比，那麼当病人在治疗时，因为有这音乐可以使病人的焦虑跟紧张获得舒缓。

Features: high efficiency, small amplitude and high frequency of screening; it differs from the conventional screens with breaking of the surface tension of pulp and small granularity high speed vibration on sieve cover and accelerates the separating of large-density useful mines and increase the contacting probability of the materials smaller than output granularity and the sieve pore.

高频筛效率高、振幅小、筛分频率高。与普通筛分设备的原理不同，由于高频筛采用了高频率，一方面破坏了矿浆表面的张力和细粒物料在筛面上的高速振荡，加速了大密度有用矿物和析离作用，增加了小于分离粒度物料与筛孔接触的概率。

Numerical simulations and analytical results show: in longitudinal and oblique seas, ship may be subjected to primary parametric resonance with large roll amplitude and even capsizing, when encounter frequency is near the twice of roll natural frequency, wave length and ship length are of the same order and the wave height is larger than a certain value; in oblique seas, ship roll motion is a forcedly-parametrically excited oscillation, primary resonance occur as the encounter frequency is near the roll natural frequency, which may lead to large rolling and capsizing too.

数值仿真和解析分析结果表明：在纵浪和斜浪中，当遭遇频率接近船舶横摇固有频率的两倍，波长和船长接近，波高超过某一阈值的时候，船舶会发生主参数共振，产生大幅横摇甚至倾覆；在斜浪中，船舶发生的是参强激励横摇运动，遭遇频率接近横摇固有频率时，还会激起横摇主共振，同样会产生大幅横摇甚至倾覆。

Pitch frequency by the sound level of the object decision, high frequency sound on the high, low frequency sound is low, the existing international standard pitch was in May 1939 in London by the International Standards Association of a1 = 440 Hz.

音高是由发音物体振动频率的高低决定的，频率高声音就高，频率低声音就低，现行的国际标准音高为1939年5月国际标准协会在伦敦通过的a1＝440赫兹。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
