The invention discloses a molecular marker InDe1587 for detecting a rice blast resistant gene Pigm(t) of rice #4. The molecular marker InDe1587 disclosed by the invention is positioned at the sixth chromosome 10484756-10484985bp, is spaced from a positioning range 10367733-1042226bp of the rice blast resistant gene Pigm(t) at 65.2 kg and is closely linked with the rice blast resistant gene Pigm(t); furthermore, the marker InDe1587 is high in polymorphism and the polymorphism can be realized between 87.2 percent of receptors and the rice #4 of a donor; PCR (polymerase chain reaction) products of the InDe1587 are greatly different; the marker gene type of a material can be quickly detected. The material to be detected can be detected through the molecular marker, so that whether the material carries the rice blast resistant gene Pigm(t) can be judged.

The invention relates to the technical field of heat generating materials and particularly relates to graphene heating slurry, a graphene heating film prepared by using the graphene heating slurry, and a preparation method thereof. The graphene heating slurry comprises the following raw materials including, by weight, 10 to 25 parts of ball-milled graphene powder, 5 to 10 parts of solvent and 60 to 75 parts of heating carbon paste. The graphene heating film includes a base film and the graphene heating slurry. The graphene heating slurry and the graphene heating film of the present invention have excellent thermal conductivity and electrical properties, and the problem that the power of the heating carbon paste is prone to attenuate in the long-term use of the heating film in the prior artcan be effectively improved.

The invention discloses a lattice type steel reinforced concrete superposed beam, and belongs to the field of architectural structures. The lattice type steel skeleton of the lattice type steel reinforced concrete superposed beam consists of combined profile steels and reinforcing steel bars; the combined profile steels are formed by connecting upper square steel pipes with middle and bottom profile steel pieces; the reinforcing steel bars consist of upper reinforcing steel bars and lower reinforcing steel bars; the upper reinforcing steel bars are arranged above the upper square steel pipes; the lower reinforcing steel bars are arranged at the lower parts of the combined profile steels; vertical inner stirrups are hooped around the reinforcing steel bars above the upper square steel pipes of the combined profile steels and the bottom profile steel pieces or the reinforcing steel bars below the bottom profile steel pieces to form a cage; concrete is cast in casting holes of the square steel pipes of the lattice type combined profile steels and a transverse outer stirrup hooped cage to form a prefabricated lattice type steel reinforced concrete lower beam; after a prefabricated floor is built on the formed prefabricated lattice type steel reinforced concrete lower beam, a lattice type steel reinforced concrete upper beam is cast in situ to form an integral superposed beam. The lattice type steel reinforced concrete superposed beam improves the torsion resistance, satisfies the bearing capacity requirement of the beam body in the construction and use phase, and effectively increases the building clearance.

The invention belongs to the field of breeding of plants and discloses a molecular marker MAG7237 of a wheat fusarium head blight infection resistant gene Fhb4 and application of the molecular marker MAG7237. The genetic distance between the molecular marker MAG7237 and the Fhb4 gene is 0.34 cm. The molecular marker most closely linked with the Fhb4 is acquired by the invention for the first time in the world. The molecular marker is a co-dominant marker with the advantages of being convenient to detect, and stable and simple to amplify; by adopting the marker MAG7237 to detect the Fhb4 gene, the existence of the Fhb4 or not and the existence state can be determined, and the fusarium head blight resistance of the wheat can be forecasted; and furthermore, the plants with the Fhb4 can be fast screened and used for breeding of disease-resistant varieties.

The invention provides a soybean sauce microbial immobilization fermentation composition, a preparation process and a use method and particularly relates to the technical field of production of seasonings. The fermentation composition includes: low-fat pectin, water, zygosaccharomyces rouxii, zygosaccharomyces sojae, torulopsis etchellsii, pediococcus halophilus, tetracoccus sojae, an MgCl2 solution, egg white, azotobacter chroococcum and trehalose. When being used for fermentation of soybean sauce, the fermentation composition is stirred and mixed with soybean sauce mash, then nitrogen is fedfor performing fermentation; finally the fermented product is filtered to obtain a fermented liquid. The fermentation composition is toxic-free and environment-friendly, is anti-stress and anti-corrosion and can be recycled; when being used for fermentation of soybean sauce, the fermentation composition can reduce fermentation period, and the fermented liquid is high in contents of soluble non-salt solids, total nitrogen and amino acid nitrogen.
