用光电容积描记器检测误差信号，用电螺管作为液压机构的推动器。
The error signal is detected by the transmittance photoelectric plethysmograph. An electromagnetic solenoid is adopted for use as the hydraulic actuator.
因此，导纳法容积描记术可作为冠心病左心功能测试与评价的手段之一。
Therefore, admittance plethysmography can be used as a means to examine and evaluate the left heart function in patient with coronary disease.
