Abstract: Provided is a hemostatic composition comprising trypsin and zeolite, wherein pore channels of the zeolite are micropores, the zeolite contains divalent metal cations, and the mass ratio of the trypsin to the zeolite is 1:200-4:10. In the present invention, the trypsin specifically binds to the zeolite, allowing the trypsin to maintain a certain conformation on the surface of the zeolite and to obtain a higher procoagulant activity, thereby obtaining a hemostatic composition with an excellent blood coagulation effect. The hemostatic composition of the present invention has the advantages of a simple preparation method, low cost and convenient use, and can be widely used in hemostasis during trauma and operations, especially in emergent hemostasis in hemophilia patients.

Abstract: A method for displaying and detecting temperature field distribution of a fluid surface applies a stimulus-responsive compound to high-resolution and high-precision imaging of a temperature field of a fluid for the first time. Under physical or chemical stimulation, an imaging developer visualizes the temperature field distribution of the fluid surface. The method for displaying and detecting temperature field distribution of the fluid surface includes dissolving or dispersing an imaging reagent in a fluid, stimulating the fluid surface to change a color or a fluorescence of the imaging reagent, collecting images of a generated color or a generated fluorescence to obtain a temperature field distribution diagram of the fluid surface.
