In the apparatus of the PYM-20, output 1973--1976 the factual errors in the anode voltage reach 30%, which impedes standardization of the roentgenography conditions. In order to take account of the factual error a reduced setting of voltage by one-two positions is recommended.
在PYM - 20装置1973 - 1976年的输出中，阳极电压的实际误差达到30%，这妨碍了X射线摄影条件的标准化。为了考虑实际误差，建议将电压设置降低一到两个档位。
