There was no difference of statistics in homogeneity of image under each tubecurrent.
不同管电流采集到的图像均匀性无统计学差异。
2
Results the tubecurrent decreases remarkably and the amount of radiation that doctor and patient receives decreases effectively.
结果显著地降低了管电流，有效地降低医生和患者的受照剂量。

Role: at start ballast circuits, the flip-flop because of the co-ordination of the moment have a high-voltage, so that the discharge lamp to start. Line at work to play the role of limit tubecurrent.
