Network Theorems（网络定理）
一、词汇
English Chinese
Single 一个；单个
Eg. It may consist of a single network element.
拟译：它也许仅包括一个网络元件
excitation 激励
Response 响应
homogeneity 齐次性
Superposition 可加性；叠加
Superposition theorem 叠加原理
Driving point impedance 策动点阻抗
Thevenin Theorem 戴维南定理
Norton Theorem 诺顿定理
Impendence 阻抗
Cause and Effect 原意：因果
引申义：激励和响应
strategy 策略、方法；
current division 分流
Equivalent （adj）等效的；（n）等效电路
Terminal 端口
Extend 扩展；延伸
Controlled （adj）受控的
Source coupling 电源耦合
Magnetic coupling 磁耦合
Statement 表述，描述
concerned （adj）有关的
Replace 替代
Involve 涉及的是
Null （v）置零
Test voltage 测试电压
Time-varying element 时变元件
二、短语与句子
“For+名词”放在括号内
The system has an input designated by e (for excitation) and an output designated by r (for response).
拟译：该系统输入用符号e表示（表示激励），输出用符号r表示（表示响应）。
Input/output to xx Xx的输入/输出
If the input to the system, e, cause a response, r, then …
拟译：若系统输入为e时，其响应为r，那么……
At a time 每次
A and B are linearly related A和B是线性相关的
Act
（v）作用
If cause and effect are linearly related, the total effect due to several causes acting simultaneously is equal to the sum of the individual effects due to each of the causes acting one at a time.
拟译：如果激励和响应是线性相关的，那么多个激励同时作用在系统上产生的总的响应等于每个激励分别单独作用时产生的响应的和。
Consider the network …., as shown in Figure 1. 在图1所示的电路中，网络……
Xx is to be determined. Xx待测
Due to 归因于；由…产生的
The current I will be the sum of the two current components Iv due to the voltage source acting alone as shown in figure 2 and Ic due to the current source acting alone shown in figure 3.
拟译：电流I应为电流Iv和电流Ic之和，它们分别为电压源单独作用时产生的电流Iv，如图2所示；和电流源单独作用时产生的电流Ic，如图3所示。
follow from
是从[根据]...得...出的
It follow from the methods of removing the effects of independent voltage and current sources.
拟译：它是采用去掉独立电压源和独立电流源的方法得到的。
Impedance presented to the voltage source 对电压源的总阻抗
By a current division 经过分流后
If interest is to be focused on … 如果我们仅仅关心的是……
It may contain … 它可由……组成
The two equivalents may be obtained from one another by a simple source transformation.
拟译：两种等效电路可以通过简单的电源变换来实现相互转换。
In addition 另外
It is not restricted to linear elements 它并不局限于线性元件
Insofar as
只要；在…情况下；
Insofar as I can see, the representatives are all satisfied with the arrangement.
拟译：据我了解,代表们对这一安排都感到满意。
Be available for … 可以用来……
Three methods are available for the determination of ZT.
拟译：有三种方法求解等效阻抗ZT
at sb.'s discretion
由…随意决定
All of them are applicable at the analyst’s discretion.
使用哪种方法取决于电路分析人员的具体情况
By looking into the terminals 从端口看进去
A test voltage may be placed across the terminals with a resulting current calculated or measured.
拟译：需要在端口加一个测试电压，然后测量或者计算因此产生的电流
Inject into 注入
In either case 无论哪种方法（情况） |
