一.光学分析法(optical analysis) 基于物质发射的电磁辐射或物质与电磁辐射相互 作用后产生的辐射信号或发生的信号变化来测定物质 的性质、含量和结构的一类仪器分析方法,统称为光 学分析法。 任何一种光学分析法均包含三个主要过程:1)能 源提供能量2)能量与被测物质相互作用3)产生被 检测讯号

1 Find the matrix equation in the circuit of Fig. 16-12 by nodal analysis method. Assume that each branch admittance of the circuit is 1S

In the chapter we shall begin to look at more general and more powerful methods of circuit analysis -the Laplace transform techniques

Let the initial voltages on the capacitors be represented as voltage sources in series with the capacitors and the initial currents through the inductors be represented as current sources in parallel with the inductors

In the chapter we shall develop a method for representing a sinusoidal forcing function or a sinusoidal response by a complex number called a phasor transform,or simply a phasor. By working with phasors we shall effect a truly remarkable simplification in the steady state sinusoidal analysis of general circuits
