电路 2 电路或电网络由以某种方式连接的电阻器，电感器和电容器等元件组成。如果网络不包含能源，如电池或发电机，那么就被称作无源网络。换句话说，如果存在一个或多个能源，那么组合的结果为有源网络。在研究电网络的特性时，我们感兴趣的是确定电路中的电压和电流。因为网络由无源电路元件组成，所以必须首先定义这些元件的电特性。就电阻来说，电压-电流的关系由欧姆定律给出，欧姆定律指出：电阻两端的电压等于电阻上流过的电流乘以电阻值。在数学上表达为： u=iR (1-1A-1)式中 u=电压，伏特；i =电流，安培；R =电阻，欧姆。纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到：U=Ldi/dt 式中 di/dt =电流变化率，安培/秒； L =感应系数，享利。电容两端建立的电压正比于电容两极板上积累的电荷 q 。因为电荷的积累可表示为电荷增量 dq 的和或积分，因此得到的等式为 u=，式中电容量 C 是与电压和电荷相关的比例常数。由定义可知，电流等于电荷随时间的变化率，可表示为 i = dq/dt。因此电荷增量 dq 等于电流乘以相应的时间增量，或 dq = i dt，那么等式(1-1A-3)可写为式中 C =电容量，法拉。

Firstly, the thesis mainly deals with major social pension system problems of market economy such as its target and orientation, pattern and degree in the condition of market economy. Then, I analyze numerous systems that constitute the reform of social pension system such as system construction, mechanism construction and institution construction, expounding the social pension system"s reform from system, mechanism, and institution three aspects in the way of from exteriority to interiority, from far - side to near - side, from low - level to high -level.At last, I put forward specific train of thought about how to perfect the social pension system"s reform, Analyzing the specific train of thought constituting pension balance through the analysis of pension balance through the analysis of the prediction the revenue and expenditure of pension.Analyzing the particular train of thought that further adjusting and improving the basic social pension budget through real calculation and research. Analyzing the system bound and developing direction of free employees through actual research. All these have key practical and deeply strategic significance in enriching reform theory, exploring reform method, instructing reform practice, as well as promoting the coordination of society and economy.
