floating and scattered pulse 浮大而散的脉 ; 脉浮大而散
The scattered pulse, which is scattered and disordered to gentle touch and disappears when heavily pressed.
散脉，轻按时脉搏散乱，重按则消失不见。
The lunar Orbiter laser Altimeter (LOLA) works by sending a laser pulse through an optical lense that splits it into five beams that are each scattered back after they strike the lunar surface.
月球探测器上的激光高度计(LOLA)的工作原理为：发射一束激光脉冲，利用光学镜片将其分为五道光线，当光线到达月球表面后会自动反射至激光高度计上。
For the impulse, the two-photon reactions were dominated by the initial primary (unscattered and unabsorbed) pulse and the single—photon reactions were dominated by the scattered diffuse light.
模拟结果表明，对于这种脉冲激光，光化学中双光子反应主要是由起始时未被充分散射和吸收的脉冲所驱动，而单光子反应是由经散射后的浸射光所驱动。
