The invention relates to a method for determining at least one free space in a vehicle environment of a vehicle, wherein the method has the following steps: (a) receiving at least two-dimensional contour points (11) of an object (5) in the vehicle environment; (b) assigning the received contour points (11) to a plurality of rows (8) which divide at least one field of view (4) located in the vehicle environment and considered in the scope of the method in rows; (c) for at least a portion of the plurality of rows (8), respectively within a row (8), determining as a minimum contour point (13) such a contour point (11) which has the smallest contour point distance (15) to a reference system (2, 3) of the vehicle (1) of all contour points (11) assigned to the respective row (8) within the row (8); and (d) connecting the previously determined minimum contour points (13) as one free space (6) or a plurality of free spaces (6) within the at least one field of view (4) considered.

The utility model provides a kind of cage type double photoionization source mass spectrometer based on molecular beam sampling, including photoionization unit, photoionization unit includes first casing, vacuum ultraviolet lamp and synchrotron radiation light connecting part;First casing is hollow structure with first inner cavity, photoionization region is formed in first inner cavity;First casing is equipped with the connecting hole being communicated with first inner cavity, the axis of connecting hole passes through photoionization region;Vacuum ultraviolet lamp is arranged in first inner cavity, and vacuum ultraviolet light generated by vacuum ultraviolet lamp can be transmitted to photoionization region;Synchrotron radiation light connecting part is at least partially set in first casing outside, and is connected at connecting hole.It is thus that double photoionization source mass spectrometer can utilize synchrotron radiation light to realize the photoionization of sample to be measured, and when synchrotron radiation light is unavailable, the photoionization of sample to be measured can be realized using the vacuum ultraviolet lamp, to alleviate the problem that cannot meet experimental demand due to synchrotron radiation light machine tense.

The utility model provides a high-temperature chemical preparation tank, and relates to the technical field of chemical preparation tanks. The front end of the chemical preparation tank is connected with a sealing tank cover; a base is mounted at the bottom of the chemical preparation tank; two high-temperature-resistant sealing rings A and two high-temperature-resistant sealing rings B are mounted in the melting tank; gears are respectively mounted on two opposite sides of the outer part of the chemical preparation tank, and a positioning pin is inserted into the outer part of the chemical preparation tank. The connection portions of the front tank body, the middle tank body and the rear tank body can be adjusted according to the number of livestock and poultry died of illness, the internal volume of the tank is changed, the internal free space of the tank is reduced, rapid pressurization is achieved, the high-temperature-resistant sealing ring A and the high-temperature-resistant sealing ring B are matched with each other, the internal high-pressure sealing performance of the tank is guaranteed, and the service life of livestock and poultry died of illness is prolonged. Livestock and poultry died of illness become grease under the action of high-temperature steam, and the time needed by high-temperature melting of the livestock and poultry died of illness is shortened.

The invention provides a processing method for enhancing reliability of flash memory data and a flash memory. The processing method comprises the following steps: acquiring to-be-written data by the flash memory; when it is determined that the written physical page cannot be filled with the to-be-written data, filling data of a free area are determined according to the size of the free area of the physical page, and the filling data are data which are related to the to-be-written data and have a verification function; and writing the to-be-written data and the filling data in the physical page. It can be seen that in the application, the flash memory dynamically adjusts the filling strategy through the size of the free area and the to-be-written data, so that the free space of the physical page can be reduced, and since the filling data is the data which is related to the to-be-written data and has a verification function, the error correction capability of the data can be enhanced, and the integrity and reliability of the data can be enhanced.

The utility model discloses a fixed bed gas producer furnace bottom assembly with an inner filling device, which comprises a furnace bottom shell and an ash tray positioned in the furnace bottom shell, a fixed ring is arranged below the ash tray, the fixed ring is connected with a big gear ring for driving the fixed ring to rotate, and the big gear ring is connected with a small gear ring. The side wall of the furnace bottom shell is provided with an open hole allowing the driving gear to enter and meshed with the large gear ring, and a filling part for reducing entering of high-temperature steam is arranged between the furnace bottom shell and the ash tray. The utility model has the beneficial effects that the filling part is arranged in the unoccupied space in the furnace bottom assembly, so that the unoccupied space is reduced, the waste of steam is further reduced, and the amount of waste water needing to be treated in the gas making process is further reduced; moreover, when sudden power failure occurs, serious accidents can be avoided.

The utility model discloses a lead frame for multiple chips, which belongs to the field of lead frames and comprises a frame body, a plurality of chip mounting units are arranged in the frame body, and transverse rectangular partition grooves and longitudinal circular partition grooves are arranged in the middle of the frame body. Transverse side ribs are arranged between every two adjacent columns of chip installation units arranged transversely, longitudinal side ribs are arranged between every two adjacent columns of chip installation units arranged longitudinally, each chip installation unit comprises three independent base islands arranged in the center, the three base islands are each independently provided with a pin, and the pins are arranged in the three base islands. Positioning holes are formed in the top and the bottom of the frame body.
