| 摘 要： | 用国产金属帽头ＹＡＧ激光传输系统以不同能量及不同时间照射狗主动脉壁。结果显示：照射标本有消蚀坑形成，能量固定１５Ｗ随照射时间延长消蚀坑加深但非直线关系。而时间固定为３秒随照射能量加大消蚀坑加深，二者显直线正相关，提示穿透动脉壁总能量随照射时间不同亦不同，照射时间短需总能量小，时间长需总能量大。

| Abstract: | hina-made metal-capped YAG Iaser transporting system has
been applied to dog aorta with vari-ous energy and various time duration. The results showed
cautery pits formation. With a constant ener-gy of 15W,the cautery pits deepened as the
duration increased, but no linear relation was observed.While under a constant duration of 3
seconds,the cautery pits deepened as the energy increased , andthere was a linear relation
between them. This implies that the total energy for artery wall penetrationdiffers as the
duration changes. Less total energy is needed within a shorter time, and more total energyis
needed within a longer time. |
