网络分析法(ANP)作为一种决策过程，它提供了一种表示决策因素测度的基本方法。这种方法采用相对标度的形式，并充分利用了人的经验和判断力。在递阶层次结构下，它根据所规定的相对标度—比例标度，依靠决策者的判断，对同一层次有关元素的相对重要性进行两两比较，并按层次从上到下合成方案对于决策目标的测度。(As an decision-making process, Network Analysis (ANP) provides a basic method for measuring the measurement of decision factors.This approach takes the form of a relative scale and takes full advantage of human experience and judgment.Under the hierarchical structure of the hierarchy, it relies on the relative scale of the scale-scale scale, and relies on the judgment of the decision makers to compare the relative importance of the elements of the same level in pairs, and to synthesize the scheme from top to bottom according to the hierarchy.)

说明：  1.用差分法求解电容器x轴上的电位分布和原点O点的电位值。（不考虑电容的电磁效应） 2.通过MATLAB仿真实现八木天线的工作原理，获得八木天线的输入阻抗、天线增益、E面方向图和H面方向图。(1.The difference method is used to solve the potential distribution on the x-axis of the capacitor and the potential value at the point O. (without considering the electromagnetic effect of capacitors) 2.The working principle of Yagi antenna is simulated by MATLAB. The input impedance, antenna gain, E-plane pattern and H-plane pattern of Yagi antenna are obtained.)

We compare the energy efficiency of some transmission schemes in wireless sensor networks. By constraining the system to end-to-end throughput requirements, we assume that the nodes in multi-hop and cooperative schemes operate at a spectral efficiency which is twice that of the single-hop transmission. By taking into account the energy consumption of the RF circuitry, we show that cooperation may be considerably more energy efficient than non-cooperative schemes even in small transmission ranges, specially if a feedback channel is available.
