【摘要】 根据原来电介质损耗角的定义,在电容损耗电桥中,无法采用幅值与相位分离平衡的运算方法。按照阻抗统一运算,采用幅值与相位分离平衡,所得的损耗因数必为负值,这与传统分析方法的结果不一致,这一矛盾只有采用导纳统一运算后才能得到解决。为此作者建议,应根据导纳统一运算的见解,对电介质损耗角重新加以定义。更多还原

【Abstract】 In the capacitance loss bridge, according to the original definition of the dielectric loss angle, it is impossible to adopt the calculating method of separate equilibrium on the value-phase. On the other hand, by using the separate equilibrium calculation, the dissipation factor must be a negative value according to the unifying impedance calculation, which is at variance with the result of the conventional method of analysis. These contradictions can only be solved by employing the unifying admittance calculation. It is thus proposed that the definition of the dielectric loss angle be redefined the light of the unifying admittance calculation concept.更多还原
