Microvalves are pided into active microvalves and passive microvalves according to driving mechanisms of microvalves in microfluidic systems.
依据微流体系统中微阀的驱动机理,将微阀分为有源微阀和无源微阀两大类,然后对这两大类进行细分,将有源微阀分为压电、磁、静电驱动、热驱动、相变、双稳态、外部驱动等类型,将无源微阀分为悬臂梁式、薄膜式、毛细管、扭矩驱动等类型。
In this article we analyzed the corresponding relationships between the differential zero-crossing and the peak position of laser pulse after the quasi-gaussian laser pulses passing the active CR differential circuits.
分析了准高斯激光脉冲通过有源CR微分电路成形为双极性脉冲后,微分过零点与激光脉冲的峰位之间的对应关系。
