摘要： A supercritical fluid chromatography system comprises a first pump for pumping a first flow stream comprising a compressible fluid and a second pump for pumping a second flow stream comprising a modifier fluid. The second pump is in parallel with the first pump. A column is located in a combined flow stream. The column is located downstream of the first and second pumps. The combined flow stream comprises the first flow stream, the second flow stream, and a sample. A detector is located downstream of the column. A gas-liquid separator is located downstream of the detector. The gas-liquid separator is configured to vent a majority of the compressible fluid while maintaining a majority of the sample, thus preventing aerosolization of the flow stream and minimizing sample loss as well as cross contamination. An open bed collector is located after the gas-liquid separator.

摘要： A mixing device for use in a chromatography system, the device includes an exterior housing having a first end and a second end and a hydraulic flow connector at the first end of the exterior housing. A cartridge including a chamber is enclosed within the exterior housing. The chamber has at least one wall defining an interior volume having a shape, wherein the shape of the interior volume creates a turbulent flow condition to mix at least two fluids and provide flow through the cartridge during operation of the chromatography system. The chamber also retains the sample, thereby ensuring that the sample is focused in the chamber such that a more narrow bolus of sample enters the chromatography column.

摘要： A USB receptacle connector (1) comprises an insulative housing (10), a plurality of terminals (14) received in the insulative housing and a shell (11) covering the insulative housing. The frond end of the shell forms a mating port (111) for insertion of a mating plug connector (1′). Either of two sidewalls (112) of the mating port defines a contact tab (115) which makes the shell of the USB receptacle connector always contact with a shell (11′) of the mating plug connector. Thus, the two shells are continuously grounded so as to ensure reliable grounding and EMI shielding.

摘要： A method of pre-controlling the shapes of a continuous-casting slab head and tail for reducing the cut amount of the head and tail of the hot rolling intermediate slab. The continuous-casting slab head and tail, is cut into a shape such that an end surface of the head concaves inwards and the tail projects outwards. The head and tail of a slab is cut in a curve that is symmetric to the center line in width thereof. Arc height, i.e. a maximum value of the concave amount at the head or that of the projection amount at the tail, is controlled within 0 mm-50 mm.

摘要： A base station includes multiple edge nodes and a central node. The edge nodes are configured to perform communication with a user equipment, and execute baseband processing and mutual conversion between baseband data and radio data, in which the multiple edge nodes belong to one or more edge node groups, and each edge node group includes at least one edge node. The central node is configured to perform communication with the multiple edge nodes, manage the multiple edge nodes, and perform resource sharing so that resources are shared by the multiple edge nodes. The base station is divided into two levels of architecture, namely, a central node and an edge node, and the central node implements resource sharing so that resources are shared by the edge nodes, so that a resource sharing degree in the base station is enhanced.
