The invention discloses a crystal form A, a preparation method and application of a compound with a structural formula shown as a formula I. An X-ray powder diffraction graph (XRPD) of the crystal form A shows characteristic peaks at the following 2theta angles: 2.9 + / - 0.2 DEG, 13.6 + / - 0.2 DEG, 17.3 + / - 0.2 DEG and 18.6 + / - 0.2 DEG.

The invention provides a novel pipeline of a fire fighting truck. The novel pipeline of the fire fighting truck comprises a water pump, a tank cannon, an outer water absorption pipeline, an inner water absorption pipeline, a foam liquid discharge pipeline, a cannon water discharge pipeline, an inner water injection pipeline, a left water discharge pipeline and a right water discharge pipeline, wherein the tank cannon is connected with the water pump through the cannon water discharge pipeline; the cannon water discharge pipeline is connected with the inner water injection pipeline; the inner water injection pipeline is connected with a tank body through a groove-type hoop I; the tank body is respectively connected with the foam liquid discharge pipeline and the inner water absorption pipeline; the foam liquid discharge pipeline is connected with the outer water absorption pipeline through a linking mechanism; the inner water absorption pipeline is connected with the outer water absorption pipeline through a groove-type hoop II; the outer water absorption pipeline is connected with the water pump. The main pipeline parts of the novel pipeline of the fire fighting truck are connected through the groove-type hoops. The novel pipeline is simple and convenient to process and install, safe in construction, good in system stability, convenient to maintain and low in space occupation.

The invention discloses a crystal form B, a preparation method and application of a compound with a structural formula shown as a formula I. An X-ray powder diffraction graph (XRPD) of the crystal form B shows characteristic peaks at the following 2 theta angles: 2.9+ / - 0.2 DEG, 6.5+ / -0.2 DEG, 12.6 + / -0.2 DEG, 13.1 + / -0.2 DEG and 20.6 + / -0.2 DEG.

The invention relates to the technical field of swine pseudorabies viruses, and relates to a swine pseudorabies virus variant XF-1 strain, a preparing method thereof and applications of the strain. The accession number of the variant is CCTCC NO V201654. The swine pseudorabies virus variant (the XF-1 strain) is adopted to prepare an inactivated vaccine, and safety and immunoprotective experiments are performed. Results prove that the swine pseudorabies virus variant (the XF-1 strain) inactivated vaccine has good safety, and that the immunoprotection efficiency of the inactivated vaccine is obviously higher than that of other immune groups, and therefore the virus strain is proved to have good immunogenicity, can be used for vaccine research and development for the swine pseudorabies, and has a food vaccine development prospect.

The invention discloses a water-based adjuvant of porcine circovirus type 2 inactivated vaccine and its application. The adjuvant composition of the invention can significantly improve the immune effect of porcine circovirus type 2 inactivated vaccine, and can stimulate the body to produce growth Up to 150 days of high-efficiency protection. At the same time, the preparation process of the vaccine is stable, and the side effects caused by the vaccine immunization are small and have unique advantages. The preparation process of the adjuvant composition is simple, does not require large-scale equipment, has low cost, and is convenient for large-scale production of vaccines.

The invention discloses a nanometer particle adjuvant, a preparation method thereof, and the application thereof in the preparation of inactivated vaccines. According to the invention, a novel nanometer particle adjuvant is obtained through preparation by the emulsion preparation and the nanometer treatment following the dissolving of different immunopotentiator and surfactant in water and oil respectively. The adjuvant provided by the invention not only can remarkably improve the humoral immune response and the cellular immune response of various bacterial and viral inactivated vaccines, butalso has unique advantages in the preparation process, the stability, the immunity duration and the side reaction of vaccines.
