查询词典 frequency band

The outlines of thesis are as follows: In order to solve the problems that noises such as corona can not be removed by routine electrical measurement methods and the signal of PD generated from the GIS can be picked up effectively, the transmission character of electromagnetic wave generated by PD in GIS is studied. The ultra high frequency band of the signal is chosen to solve the problem.

主要工作如下：针对GIS局部放电在线检测技术中既要避开常规电气方法难以排除的电晕等干扰，又要有利于接收信号的关键问题，研究了GIS内的局部放电信号发出的电磁波的传输特性，选择超高频段信号为接收信号。

Since the detected signal isalways limited, according to the uncertainty principle, the frequency band is infinite.

由于观测的心率变异信号总是有限长的，根据不确定原理，所能得到的频带必然是无限的。

The workunits generated at first by the S5R4 workunit generator all at the upper end of the runtime variation for a given frequency band. They should average out over time, but at the beginning we got all "bad" ones.

S5R4目前的任务单元计算时间都偏长（译注：所以导致得分率的实际降低比例超过了25%），以后的任务单元计算时间平均来说会比较正常，但现在最早这批全是时间比较长的

In this case the sound, which emerges beyond the framework of frequency band, which corresponds to human voice, is filtered, and user hears against the background music purified and improved speech of collocutor.

在这种情况下，健全的，这以后出现的框架内，频段，相当于人类的声音，是被过滤的，和用户听到的背景音乐净化和改善讲话collocutor 。

In this case the sound, which emerges beyond the framework of frequency band, which corresponds to human voice, is filtered, and user hears against the background music purified and improved speech of collocutor.

在这种情况下，健全的，其中出现超越的框架内，频带，相当于人类的声音，过滤，用户听到反对的背景音乐，纯化和改进的讲话collocutor 。

All these characteristics can extend frequency band , reduce antennaelectric size and improve impedance characteristics. In order to miniaturization ofantenna, impedance complete compensate and matching optimization of electricallysmall antenna are brought forward, and this method is applied to the discage antennas.

从阻抗特性和辐射特性的实测数据表明，水加载单极振子天线的谐振频率能很好地向低端下移，局部水加载单极圆锥天线在保持原有宽频带特性的前提下，以较少的效率损失实现了较大范围向低频区扩展，即天线小型化，这将为短波超短波波段天线进一步的小型化设计提供很好的思路。

However, the interceptive white noise process must be used for design if the seismic power spectrum concentrates at high frequency band.

但是，如果地震功率谱集中在高频，必须按高频部分截断白噪声设计。

As one of major monitoring techniques for forecasting the disasters in mine, Microseismic signal contains some special characteristics, such as rich composition of the spectrum and wide frequency band.

在煤矿开采过程中，煤层底板突水、淹井事故时有发生，严重影响煤矿的正常生产，但目前其预测的可靠程度与生产实际还有较大的差距。

Perhaps this is more noticeable because of the weaker bass presence, and the narrowish soundstage, which could shift attention to these areas of the frequency band.

也许是因为低音呈现缺少的原因，这方面更明显。

Multiple frequency band antennas are pivotally connected to electronic devices such that coaxial connectors are not required.

多频带天线被枢轴连接到电子设备上以致不需要同轴连接头。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
