摘要： The aerosol particulate matter collecting device includes a shell, a first electric field component, a second electric field component and the collection unit. The first electric field component is connected to the shell and forms a first electric field area, the second electric field component is connected to the shell and forms a second electric field area, the second electric field component includes a first plate and a second plate, and the electric property of the first plate is opposite to that of the first electric charges; a bottom plate of the collection unit is located between the first plate and the second plate, protrusions are arranged on the bottom plate, a flow channel for accommodating collecting liquid is formed in the bottom plate, the protrusions are configured to enable the flow channel to extend along a curve.

摘要： The present invention discloses a bidirectional collapse-proof damper with a macroscopic NPR structure and a bridge structure having the same, comprising a sleeve and a sliding rod; by adding a structure of a reducing part and a limiting body, a sliding gap exists between both ends of the limiting body and both inner ends of the reducing part; the rod body is connected with the inner side wall of the sleeve through an elastic element; the limiting body and the rod body can realize bidirectional slip in the sleeve, which have multi-level seismic performance.
