这就是一般所说的蒸发冷却过程，使AMO物理学家能够近似的靠近绝对零度和建立简单的宇宙热寂模型.

This so-called evaporative cooling process has allowed AMO physicists to reach the subnanokelvin domain and to achieve what are arguably the coldest objects in the Universe.

近似同步法采用了不严格相等的采样间隔，从而使每个采样点都尽量靠近同步采样点。

ASM samples signal with no strictly equal intervals in order that each sampling point is close to synchronous sampling point.
