电阻热涨落对RL电路电流的影响

The Influence of Reistance Thermai Fluctuation on RL Circuital Current

利用随机理论方法研究了ＲＬ串联电路中电阻的热涨落对电路中电流暂态过程的影响，计算了 电流的定态几率密度，平均电流与电流的涨落。结果表明，电阻的热涨落强度对电流的暂态 过程有很大影响。当温度很高且变化不定时，电流的变化规律呈明显的随机性。

By the method of random theory,the influence of resistance thermal flutuation on circuital current transient process in a RL series circuit is studied And the s table probability density in current,average current and current flctuation are calculated.The strength of resistance thermal tluctuation has a great influence on current transient process.When temperature is high and unstable,the current c hanges with randomness.
