The revascularization of ACL following RF treatment originates from the synovial membrane to the RF-penetrated parts. The repair of the amph-portions is better than that of the midportion, which indicates that the optimal parts for exercising RF reefing on is the amph-portions of ligament.

射频处理后前交叉韧带的再血管化模式是由滑膜向韧带射频渗透区域进行的，韧带两端组织的修复优于韧带的中间部分，提示射频紧缩的最佳部位为韧带两端。

The RF reefing was carried out to the 1/3 midportion or 1/3 each of the amph-portions (amph-portions group) in the way of moving RF probe from one end to another at a speed of 2.5 mm/s, avoiding any missing or overlapping. Histomorphological observation was taken at week 6 and 12 following reefing respectively.

紧缩方式：射频探头从一个端开始以2.5 mm/s速度开始向另一端移动，无遗漏，不重叠，射频紧缩中间部组紧缩韧带中间1/3，射频紧缩两端组紧缩两端各1/3，术后6，12周进行组织形态学观察。

The results suggested that dual atrioventricular nodal pathways in patients with long PR have some electrophysiologic characteristics of their own and the radiofrequency ablation of slow pathway is safe and effective in these patients.

Based on the requisition of wireless system debugging, this paper develops a novel radio-frequency beaconing. Design method and system constitution of a novel beaconing based on PLL IC PE3336 are given, and the accomplish method of the system's hardware and software arc expounded. The test results show that the beaconing adopted in this method has a reliable and stable frequency conversion features. The more applications in the wireless system find that the users can set necessary frequency conveniently. Especial1, the friendly man-machine interface makes the operation is more flexible. It is as excellent performance-price-ratio beaconing, and as a signal source, it can be used in the research and the debug procession of variable radio-frequency components.
