The present invention relates to a method for separating biological macromolecular component by using two-dimensional or multidimensional capillary electrophoresis and its interface. The biological macromolecular component undergone the process of one-dimensional capillary electrophoresis separation can be passed through the interface and fed into two-dimensional capillary electrophoretic separation operation to implement two-dimensional capillary electrophoresis, the small molecular substance can be diffused and freely permeated through the hollow fibre in the interface and can obtain balance in it, and when the described biological macromolecular component is flowed through the interface, the buffer solution containing low molecular substance can be on-line added / removed into the hollow fibre in the interface.

The invention discloses a light emitting diode (LED) four-channel multiband light source which comprises four LED light source modules and a co-focus lens. Each light source module comprises an LED light source, a condenser and an optical filter; the included angle of the optical axes of the optical filter and the light source module is 72 degrees, the included angle of the optical axes of a second light source module and a first light source module is 36 degrees; the included angle of the optical axes of a third light source module and the second light source module is 36 degrees; the included angle of the optical axes of a fourth light source module and the third light source module is 36 degrees; the optical filters of the second light source module, the fourth light source module, thefirst light source module and the third light source module are arranged into four sides of a regular pentagon in turn; and the optical axis of the first light source module is superposed with the optical axis of the co-focus lens. The LED four-channel multiband light source has the advantages of freely combined multi-wave light, capability of realizing quick switching test, high luminous efficiency, long service life, high brightness and low power consumption, is especially suitable for the bio-medical field in rapid diagnosis of cell detection, photographic recording, pathological section, and is also suitable for the investigation and the inspection of physical evidence at the scene.

The invention relates to a storage device. The storage device comprises a plurality of box bodies, the box bodies are connected in the vertical direction, each box body is provided with an outer top face and an outer bottom face, a connecting groove is formed in one of the outer top face and the outer bottom face, and / or a connecting table is arranged on the other one of the outer top face and the outer bottom face in a protruding mode; and the connecting table is matched with the connecting groove of the adjacent box body, the inner side face of the connecting groove is a first guide inclined face, the outer side face of the connecting table is a second guide inclined face, and the second guide inclined face is matched with the first guide inclined face. According to the storage device, the multiple box bodies are conveniently connected in a mode that the connecting tables are matched with the connecting grooves, the stability of the connected box bodies is ensured, the first guide inclined faces and the second guide inclined faces on the box bodies provides a guide effect for the connection between the adjacent box bodies, a user can freely combine the box bodies conveniently, the box bodies can be connected conveniently, and the problem that an existing shoe box is inconvenient to use is solved.

The invention discloses a support device for foundation pit engineering and a support method, and relates to the technical field of construction. The support device comprises a first protecting plateand a second protecting plate; prisms are uniformly distributed on one surfaces of the first protecting plate and the second protecting plate; through holes are formed in one surfaces of the protecting plates; drainage ports are formed in one surfaces of the protecting plates; one ends of the drainage ports are fixedly connected with drainage pipes; drainage holes are formed in the peripheral sidesurfaces of the drainage pipes; bolts are uniformly distributed at the tops of the protecting plates; and bolt grooves are uniformly distributed at the tops of the protecting plates. Through the effects of the first protecting plate and the second protecting plate, the advantages of support, reinforcement and protection of the side walls of foundation pits and surrounding environments are achieved; through the effects of the prisms, the advantage of firmer fixation of the protecting plates through increment of the friction force between the protecting plates and soil is achieved; and throughthe effects of the drainage ports, the drainage pipes and the drainage holes, the advantage of drainage of underground water in the soil is achieved.
