The application provides a vehicle body front end structure and a vehicle. The vehicle body front end structure comprises a reinforcing support arranged on a front bumper, the reinforcing support comprises a main body part and an extension part arranged at the bottom of the main body part; the main body part is connected with a bumper body of the front bumper, the bumper body has a mounting area for mounting a license plate, the extension part extends downward along the up-down direction of the whole vehicle, and a connecting part is arranged on the extension part, the connecting part is located at the rear side of the mounting area and is connected with a lower grille of the front bumper. The vehicle body front end structure has the extension part arranged on the main body part and connected with the lower grille, which is beneficial to improving the strength of the vehicle body front end in the up-down direction of the whole vehicle and the continuity of force transmission, and the fastening stress point when the connecting part is connected with the lower grille is located in a non-visual area, which is beneficial to solving the problem of visual light shadow disorder of the front bumper caused by force pulling and improving the appearance of the front part of the whole vehicle.

The application discloses a composite core which can be used for extrusion casting and pressure casting, and is composed of an inner core and a sand core layer, and can be used for extrusion casting and pressure casting, and can make the core free from preheating, and the sand core layer can be easily collapsed, so that the core can be easily taken out after the casting is completed.

The invention relates to the technical field of separation and extraction of natural products, in particular to a method for supercritical separation and extraction of astaxanthin, which comprises the following steps: (1) weighing raw material components in parts by weight; (2) mixing a biomass raw material rich in astaxanthin with the functionalized deep-eutectic solvent, and performing physical field enhanced extraction to obtain an extracting solution; (3) filtering the extracting solution through a vibrating membrane, and purifying to obtain a trapped fluid containing astaxanthin; and (4) carrying out supercritical CO2 back extraction on the trapped fluid, separating to obtain an astaxanthin product, and recovering the functional eutectic solvent. According to the method, continuous membrane separation and purification under the eutectic solvent system are realized, the purity of astaxanthin and the proportion of all-trans astaxanthin are maintained while the extraction rate of astaxanthin is increased, the solvent can be recycled after being recovered, and the production cost and waste liquid discharge are greatly reduced. All the raw materials are nontoxic and harmless, no organic solvent is used in the technological process, and good application prospects are achieved.
