The preparation process of the levosimendan for injection is simple, adopts degerming, filtering and freeze-drying processes, and is suitable for industrial production.

Automatic calcium carbide discharging system

The automatic calcium carbide discharging system comprises a circulating vehicle rail system and a calcium carbide furnace body, the calcium carbide furnace body is located at one end of the inner side, three furnace tongues distributed in a circumferential array mode are arranged on the outer wall of the calcium carbide furnace body, and a plurality of calcium carbide vehicles movably connected end to end are densely distributed on the circulating vehicle rail system; the lower end opening of the furnace tongue is provided with a swing groove, and the lower end opening of the furnace tongue can extend to the middle of the upper end opening of the swing groove; when the calcium carbide furnace main body is discharged through the furnace tongue, liquid calcium carbide flows into the swing groove through the furnace tongue, and the liquid calcium carbide in the swing groove can only flow into the calcium carbide pot below the furnace tongue through the lower discharge port in the swing groove ...

Prescription compatibility analysis method based on grey correlation model

The invention discloses a prescription compatibility analysis method based on a grey correlation model, which comprises the following steps of: measuring the importance degree of medicines by adopting grey correlation degree, and then performing composition by adopting Kmeans clustering so as to provide a new research scheme for prescription compatibility, and specifically comprises the following steps of: (1) determining a reference sequence; (2) determining i (k); (3) calculating a correlation coefficient; (4) calculating a grey correlation degree; and (5) carrying out clustering analysis on prescription compatibility to provide a new research scheme. Compared with the prior art, the potential rule of the prescription is dominated, and the treatment thought of traditional Chinese medicine is broadened. The'macroscopic compatibility 'rule of the prescription is explored according to part of known rules, the research result has the advantages of large inter-group difference and small intra-group ...

External driving power supply for LED illuminating lamp
