the theory and corresponding experiment of the intensity profile modification of a gaussian laser beam by an ultrasonic standing wave (controlled by electricity) are reported and discussed.
本文报道和讨论了在超声驻波作用下实现激光高斯光束空间强度整形的原理与实验。
objective to evaluate the safety of ultrasonic standing wave blood separation technology from two point of view:rheology and blood cell composition.
目的:从血液流变学和血细胞成分两方面来评价超声驻波血细胞分离机的安全性。
conclusion ultrasonic standing wave blood cell separation technology is safe and reliable, and is similar to centrifugal blood separation method.
