频带

A broadband circular polarization antenna is then presented. Besides, we discuss how the different size of ground plane affect the antenna's performance.

其次，本文设计了一个宽频带的圆极化天线，并在此基础上讨论了不同大小的地板对圆极化天线性能的影响。

The transformation progress of critical-band level to sound loudness in acoustic-structure coupling field of an enclosed cavity was illustrated which is caus...

结果表明，观测点声响度变化并不与板厚的变化成比例关系。通过合理选择板厚，可以在观测点上重点关注的相关频带内获得需要的声响度，从而为产品声响度设计提供方法。

In chapter 4, three full-rate BBPFDs and a half-rate BBPFD are presented for the continuous-rate CDR circuit.

第四章里详述了连续性频带时脉资料回覆电路的实作，其中应用了我们所提出的三个全速率相位频率侦测器和一个半速率的相位频率侦测器。

Pn wave velocity structure and anisotropy in the central Tien Shan are investigated by using seismic arrival data from the temporary broadband network and the Kyrgyzstan seismic network.

利用宽频带流动地震台阵GHENGIS和吉尔吉斯地震台网KNET记录的地震波走时数据，反演了中天山地区的Pn波速度结构和各向异性。

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。
