将定子一种极数的磁场感应于转子绕组中的电流，通过集电环和电刷，但由另一种极数的磁场感应的电流，却自动流经另一闭合回路，而不通过集电环和电刷：于是，如果后一种极数是电动机的工作基波磁场，而把前一种极数作为用以起动的谐波磁场，则可以把起动电阻直接焊接在转子绕组上，而把集电环和电刷取消，从而出现了转子电路上无集电环、无电刷、无触点的谐波起动绕线型感应电动机。

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding. TTE guiding His bundle elactric cahteter、high right atrium electric cahteter and right ventricular electric catheter in site: It is difficult using TTE singly since there are too many crossroads in inferior venous.
