窄频带

But it has some defects, such as narrow frequency band and resistance are poor.

但是它也存在着一些缺陷，比如频带窄、抗干扰性差等。

Another attribute is the flux or radiant power that can be delivered in that narrow frequency band.

另一个性质就是在这样窄的频带内可以给出很高的光通量或辐射功率。

In the described system, in order to transmit the narrow-band analog signals or low speed digital signals at any time and under any climatic condition, sun-blind-region ultraviolet is used as information carrier, the modulated low voltage mercury-vapor lamp is used as emission device.

所描述的系统是以日盲区紫外光作为信息载体的，用被调制的低压汞蒸汽紫外放电灯作为发射器件，以日盲型滤光片和光电倍增管或日盲型紫外光电倍增管作为接收器件，以达到在任何时间和在任何气候下完成窄频带模拟或低速数字信号的传输。

The coupling mechanism, frequency domain characteristics and propagation rule of three propagation paths of partial discharge signal

该方法所采用的测量频段较高，抛弃了以往定位方法中常用的"慢波"，不会受到窄带干扰和低频磁场耦合信号的影响；不存在定位盲区；具有足够的脉冲分辨率；所采用的频带较窄，相应的传感器较易制作。

Due to the single microstrip patch antenna is a kind of standing wave antenna, a narrow bandwidth is resulted.

由于单一微带贴片天线是驻波形式的天线，导致了其频带宽度较窄。

In order to widen the frequency bandwidth of piezoelectric vibration based generator, the structure with multi-beams and single mass is designed.

本文针对压电式振动发电机频带宽度过窄的问题，设计了多悬臂梁-单质量块结构的微型压电式振动发电机。

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。
