The tracer particles enter the smoke storage box via a smoke guiding tube. An axial flow fan is mounted on a wall surface of the smoke storage box. The tracer particles enter a cavity of the wall-surface particle distribution box via the smoke guiding tube, and the tracer particles are rectified by a rectifying plate and ejected from a spreading slit. An outlet of the spreading slit is at an angle of 15° with respect to an experiment flat plate.

Abstract: A device for defibrillation and monitoring, a monitoring component, and a component for defibrillation and monitoring, are disclosed. The device for defibrillation and monitoring includes a host and a monitoring apparatus, which are assembled and disassembled through a detachably connection. The host is capable of independently performing defibrillation operations and display defibrillation information at least. Therefore, when it is necessary to go out for defibrillation operation alone, only the host is carried to medical assistance facilities. This monitoring apparatus can independently implement monitoring functions. When it is necessary to go out for implementing separate monitoring operations, just the monitoring apparatus is carried to the medical assistance facilities. Therefore, the user flexibly selects the devices they carry according to their requirements, improving the convenience of use.

Abstract: A system and method for preparing epoxy chloropropane is provided in that by coupling three stages of high gravity reactors, the product epoxy chloropropane and water vapor are distilled from a reaction system in form of an azeotrope by adopting a water vapor steam stripping method. Further, by combining the azeotrope with the multiples stages of high gravity reactors, the gas phase mass transfer and the liquid phase mass transfer of the azeotrope are improved aiming at the features of the azeotrope in the reaction system, thus making the overall conversion rate higher. In addition, by combining steam stripping and high gravity, dichloropropanol and alkali solution are rapidly mixed for mass transfer, and the product epoxy chloropropane is rapidly distilled from the reaction system in the form of the azeotrope, such that the reaction proceeds continuously towards the direction of producing epoxy chloropropane, thus significantly improving the conversion rate.
