This utility model discloses a novel wine box, including a base box body, a top box body on the upper surface of the base box body, an inner liner fixedly connected to the inner bottom wall of the base box body, a limiting groove on the upper surface of the inner liner, and a transparent plate fixedly connected to the inner wall of the upper surface of the top box body. The base box body and top box body are mainly made of grey cardboard, which improves the box's rigidity and moisture stability, reduces the risk of deformation, and can withstand greater tensile and compressive forces, meeting environmental protection requirements. Meanwhile, the transparent plate on the top box body is made of transparent acrylic sheet, allowing direct viewing of the complete product inside the box after packaging. The base box and top box face paper are red tactile paper, fully wrapping the outer surface of the wine box, changing its color to red. The red tactile paper decoration makes the surface of the wine box smooth and delicate to the touch, with no obvious resistance, uniform color tone, no halftone dots, rich color, and a high-end visual effect.

The application provides a differential pressure driving turning method and device based on tail combined jet flow and suction flow, and the method comprises the following steps: constructing combined jet flow and suction flow excitation circuits with zero net mass flow on the left and right sides of the tail of an underwater vehicle respectively; independently regulating and controlling the start-stop and working intensity of the combined jet flow and suction flow excitation circuits on the left and right sides by a control unit, so that flow separation bubbles and local low-pressure areas are formed on one side of the tail or flow separation bubbles and local low-pressure areas with different intensities are formed on both sides of the tail; a yawing moment is generated by the differential pressure of the tail, effective turning force can still be provided under low-speed working conditions, and the low-speed failure problem of traditional rudders is solved; the structure is simple and convenient to modify: there is no exposed mechanical rudder surface and multiple propeller structure, the circuits are integrated in the tail, and the modification cost is low and the adaptability is strong.

The utility model provides a belt detection device with a self-cleaning function in order to solve the technical problem that the belt detection device is difficult to realize continuous and accurate monitoring due to the defects that the existing method for cleaning the belt detection device does not have instantaneity, stubborn stains cannot be cleaned and the cleaning function is lost due to dust accumulation. Comprising a shell, a linear light source assembly, an industrial linear array camera, a glass window and a self-cleaning mechanism, the linear light source assembly and the industrial line-scan digital camera are arranged in the shell, an image of the belt is reflected to the industrial line-scan digital camera for imaging through the glass window by means of refraction of light, and the self-cleaning mechanism comprises a driving mechanism and a brush head which is connected with the working end of the driving mechanism and located on the outer surface of the glass window. The driving mechanism drives the brush head to transversely reciprocate along the outer surface of the glass window, and the outer surface of the glass window is deeply cleaned in cooperation with water spraying of the water outlet.

This invention relates to an insecticide composition and its application method. The composition comprises two active components, A and B, wherein component A is selected from benzamide compounds represented by general formula I, and component B is selected from flupyrimin. The composition of this invention has advantages such as significant synergistic effect and delayed resistance development, and can be used to control a variety of pests.

The invention belongs to the technical field of bioengineering, and relates to a recombinant engineering bacterium and application thereof in preparation of mannitol, and the recombinant engineering bacterium is a plasmid-free strain for producing a cofactor NAD < + > by using cheap xylose and nicotinamide. The following genes are knocked out from the strain: a gene ptsG for coding protein EIICBGlc in a glucose PTS system, mtlA for coding EIICA protein in D-mannitol transmembrane transport, a D-mannitol 1-phosphate dehydrogenase gene mtlD in a D-mannitol utilization path, purine de novo synthesis regulation protein purR, and srlAE in a sorbitol utilization gene cluster. The following genes are integrated in a genome of the strain: glucose transport assisting protein glf, glucokinase glcK, xylose utilization gene cluster xylose isomerase xlyA and xylulose phosphorylase xlyB, phosphoribose pyrophosphate synthetase prs, polyphosphate kinase ppk2, nicotinamide phosphoribose transferase nadV and nicotinamide mononucleotide adenylate transferase nadM. The strain is fermented by using glucose and xylose, and provides chassis bacteria for reaction needing cofactor circulation.
