The optimal location range of the cavity resonator is dramatically shorten with NCl(a1Δ) self-annihilation.

其中，光腔位置的可选范围大大缩短，在较小的初始HI粒子数密度和适当的输出镜反射率下总输出功率大幅度降低，而随着HI粒子数密度的增加，NCl(a1Δ)自猝灭对总输出功率的影响逐渐减小。

The optimal location range of the cavity resonator is dramatically shorten with NCl(a1Δ) self-annihilation. The available power with NCl(a1Δ) self-quenching is much less than that obtained without NCl(a1Δ) self-annihilation at small initial density of HI but has little difference at large initial density of HI.

其中，光腔位置的可选范围大大缩短，在较小的初始HI粒子数密度和适当的输出镜反射率下总输出功率大幅度降低，而随着HI粒子数密度的增加，NCl(a1Δ)自猝灭对总输出功率的影响逐渐减小。

In addition, comparing with moving mirror system the rotating mirror system is of benefit to increase the mainipulating speed of an optical trap, simp lify the mechanism of an optical tweezers, reduce its cost, and shorten the cycle of completing an optical tweezers.

此外，比较分析表明，与平移反射镜系统相比，转镜系统在光镊技术中的应用可加快光镊操纵速度、简化光阱位置操纵系统的复杂程度、有利于系统开发成本的减少及开发周期的缩短。

Gecko danger, to escape from the end, the tail can also regeneration; spiders can not only foresee the impending storm front, but also quickly erect个Net knot to prevent cross-Net torn by wind and rain and no home to return to; fly bats were not birds belong to animals, it can rely on their own issued ultrasonic reflectivity of the target to determine the target insects are still obstacles; sundew, rainbow grass these plants were able to "kill" small insects as their own "food"......

壁虎遇到危险，脱尾逃生后，尾巴还能再生；蜘蛛不但可以预知暴风雨来临，而且还赶忙结个竖网，以防横网被风雨扯破后无家可回；会飞的蝙蝠居然不属于鸟类动物，它还能靠自身发出的超声波对目标物的反射来确定目标是昆虫还是障碍物；毛毡苔，彩虹草这些植物居然能"捕杀"小虫子作为自已的"食物"。。。。。。
