The invention discloses a molecular marker closely linked with a major QTL (quantitative trait loci) of the tillering angle of highland barley and application, and belongs to the field of genetic engineering, the molecular marker is an SNP (single nucleotide polymorphism) marker, the SNP marker is positioned on a 7H chromosome of the highland barley and is positioned at the 251 site of a nucleotide sequence as shown in SEQ ID No.1, the base of the site has C / T polymorphism, when the genotype of the site is CC, the highland barley has a larger tillering angle, and when the genotype of the site is CC, the highland barley has a larger tillering angle. The genotype is TT, and highland barley has a small tillering angle. The invention discloses a genetic factor for regulating and controlling the tillering angle of highland barley, and lays a foundation for genetic improvement and molecular design breeding of the tillering angle character. The SNP marker TA10 disclosed by the invention can be used for correctly genotyping in an RIL (Research Institute of Ligand) group, and effectively assists in selecting strains with a large tillering angle (C: C) and a small tillering angle (T: T).

The invention relates to the technical field of nerve block puncture needles, and discloses a nerve block puncture needle capable of enhancing the ultrasonic development effect, the nerve block puncture needle comprises a connecting part and a puncture needle tube, and a reflection cavity is formed in the tube wall of the puncture needle tube. Under the combined action of the positive pressure and the negative pressure at the two ends of the microbubble solution, gas is continuously dissolved at one end of the gas inlet cavity in the reflection cavity and enters the microbubble solution, bubbles are generated in the microbubble solution, and the bubbles are generated in the microbubble solution due to the negative pressure action at one end of the gas outlet cavity. The microbubble solution in the enrichment cavity is continuously enriched from one end of the air inlet cavity to one end of the air exhaust cavity, so that a large number of bubbles enriched in the enrichment cavity can be obviously displayed under ultrasonic waves, and the position of the needle tip can be confirmed through the flowing and gathering direction of the bubbles, so that the microbubble concentration can be accurately controlled under ultrasonic guidance. The accurate position of the needle tip can be accurately confirmed, puncture operation of medical staff is facilitated, errors caused by nerve block puncture are effectively avoided, and puncture accuracy and safety are guaranteed.

The utility model relates to the field of silage processing, in particular to a receiving device for silage processing, which comprises a receiving box, a discharge groove is arranged on one side of the lower portion of the inner wall of the receiving box, and a discharge door is mounted at the bottom of the receiving box and covers the discharge groove. The two groups of comb tooth cylinders can rotate while horizontally reciprocating in the receiving box, so that silage in the receiving box is flattened and scattered, effective assistance can be realized during discharging, reciprocating motion of the comb tooth cylinders during receiving of the silage can be realized by the aid of the structure, and the silage receiving efficiency is improved. According to the silage receiving device, silage can be effectively spread and scattered, accumulation and internal caking of the silage during receiving are avoided, when the receiving box discharges the silage outwards, the whole silage can be obliquely discharged outwards through opening of the discharging door and contraction of the telescopic supporting legs, and the discharging efficiency can be further improved through reciprocating motion of the comb tooth cylinder.

This invention discloses a composite impact-driven drilling tool, belonging to the field of oil and gas drilling technology. Addressing the problems of poor tool adaptability and asynchronous impact and reversing in existing technologies, this invention proposes a quantitative design method based on the fluid-structure interaction coefficient. The tool's actuating valve assembly includes a coaxially nested inner sleeve and a reversing valve, controlling fluid flow direction through a distribution structure. This invention defines the coupling coefficient between the geometric parameters of the reversing valve and the hydrodynamic parameters. This coefficient is jointly determined by the circumferential impact torque, reversing rotation angle, drilling fluid discharge rate, nozzle pressure drop, and the equivalent hydraulic diameter of the reversing valve, and is controlled within a specific preset range. Through the above quantitative design, the inverse relationship between the reversing angle and the discharge rate is forcibly constrained, achieving efficient synchronization of impact and reversing across the entire discharge range, effectively solving the problems of "idling" or "jamming," and significantly improving rock-breaking efficiency.

The utility model discloses an electric folding ladder for an automobile, which relates to the field of folding ladders and comprises a first ladder plate, a second ladder plate and a third ladder plate, a first lifting mechanism is arranged between the first ladder plate and the second ladder plate, and a second lifting mechanism is arranged between the second ladder plate and the third ladder plate. The folding ladder solves the problems that the lowest layer of the folding ladder is generally not in contact with the ground, so that the folding ladder needs to bear the weight of all people during use and is extremely easy to damage during use, and meanwhile, part of the folding ladder in contact with the ground cannot be smoothly built and laid on the ground due to the instability of the ground. Through the arrangement of the supporting mechanism in the device, when the first ladder plate extends out for use, the lower side of the first ladder plate can be effectively supported and assisted, so that the first ladder plate is not prone to being damaged due to bearing the weight of all people during use, and the situation that the first ladder plate cannot be used smoothly due to the fact that the ground is too uneven is also not prone to occurring.

The utility model relates to a turning-over auxiliary pad technical field, specifically disclose a multifunctional turning-over auxiliary pad for tumor patient rehabilitation, include: installation pad, the upper symmetry of installation pad is provided with two turning-over pad, the inner chamber of installation pad is provided with with two turning-over pad link to each other's adjusting mechanism, two the turning-over pad between setting up expansion pad, and expansion pad inside installation has a plurality of air bags, the utility model not only adapts the demand of different height patient, improves the practicality of turning-over auxiliary pad, still ensures the comfort and security of patient in the turning-over process, help to promote the rehabilitation experience of patient.
