天线电阻

The hardware included helicon wave antenna and focusing system.

其中硬件系统主要包括：螺旋波天线和辉光聚焦系统的设计；PCL-818HG数据采集卡输出的+5V稳定信号，经过分压电阻和三极管后，作为数控器的外部启动/停止信号，控制步进电机带动光谱仪转动；另外，为了减小光电倍增管的噪声，单独为其提供了稳定的高压直流电源。

Note : radiation resistance is not input impedance!

辐射电阻不是天线输入阻抗！

RFID tags are used in conductive ink by subtle conductive particles or other special materials (such as conductive polymer, etc.), Business card printing and membership card making to the substrate, acts as a conductor, antenna and resistance.

RFID标签用的导电油墨是由细微导电粒子或其他特殊材料组成，制卡和会员卡制作到承印物上后，起到导线、天线和电阻的作用。

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。
