摘要
在介绍一类无损耗电阻的特性和数学模型后，对无损耗电阻在应用上的重要特性进行了分析．在研究由无损耗电阻构成的系统的基础上，对无损耗电阻的参数选择和所用信号源的约束进行了探讨．结论是：由电感和开关阵列组成的无损耗电阻其输出电流的相对误差大于等于Δｔ２Ｌ·Ｒ－１；其输入信号源应使用理想电压源，而不应使用理想电流源．
The characteristics and mathematical models for first class loss free resistance are introduced,and the important features of the loss free resistance in practical applications are analysed.Based on the research work on constructive system of loss free resistance the calculation of loss free resistance parameters and the restraints of signal source are discussed in detail.The conclusion is that the relative errors of the output current of the loss free resistance composed of inductance and switch array are more than or equal to Δ t 2/(L·R -1 ) ; the input signal sources should use ideal voltage sources rather than ideal current sources.
