说明：  利用MATLAB进行飞行器四自由度仿真。(Four degrees of freedom for vehicle using MATLAB simulation.)

依据矩量法对偶极子天线和单线行波天线进行分析,将其分为多个小段,分别计算各段上的电流,然后根据电流分布计算出远场和近场的场强波瓣图,从近场随距离的明显变化得出天线近场分析的必要性。(Dipole antenna and a single-wire traveling wave antenna analysis based on the method of moments, will be divided into multiple small pieces, respectively, to calculate the current on each segment, the field strength of the far-field and near-field lobe diagram is then calculated according to the current distribution, draw antenna near-field analysis of the need for significant change with distance from the near-field.)

An electric meters are used everywhere to calculate the consumption of power. Wireless meter reading technology can save human resources and another feature of this kind of meter is, it improve the accuracy since it works on real time application, enabling management sector to access to data messages within a short period of time and accurately. Due to its wireless communication network, it just not save human and material resources but this property leads to most economical meter in terms of investment. In this paper, power consumed by the consumer is monitored by base stations through wireless network. It aims to reduce the man power for billing since the meter reading is transmitted through ZigBee and at base stations we calculate bill, save records of consumers. The most important part of this project is that we can monitor any fault in meter as well as any tempering which is used to steal the electricity.
