The invention discloses a fast solution method for a reachable state of a resource distribution system based on a binary decision diagram. The method comprises the following steps: modeling the resource distribution system by using a Petri network; representing a library in the Petri network by utilizing Boolean variables to obtain an identification vector; based on the identification variable, obtaining a feature function of an identification vector set M, and then performing compressed representation on a base station, an arc weight value and a state identification of a Petri network according to the feature function; solving a characteristic function of the transition enabling condition; and solving a reachable state set of the Petri network through mirror image calculation. According to the method, the state explosion problem existing in system model analysis can be relieved, the system reachable set can be quickly solved with small time and space, and the method has important significance for application of large-scale systems of the type.

The invention discloses a portable type uniformly-cooling first-aid medicine refrigerator, and belongs to the technical field of medical first-aid kits. The portable type uniformly-cooling first-aid medicine refrigerator mainly comprises a body which consists of a plurality of storage cabinets, a base and a cover; the base is in threaded connection with the lower part of the body; each of the storage cabinets comprises a connecting column, an outer frame, a partition plate, a sector drawer and a fixed plate; the inner part of each of the connecting columns is hollow; four averagely-distributedsplicing grooves are formed in the outer walls of the connecting columns; air outlet holes which are uniformly distributed are formed in the outer walls of the connecting columns; the outer frames pass through through holes and are connected with the fixed plates; the four partition plates are arranged and are separately and fixedly connected with the splicing grooves formed in the inner side andthe two sides of the outer frames; a circular ring arranged between the corresponding connecting column and each of the outer frames are averagely divided into four sector areas by the partition plates; the sector drawers are separately positioned in the sector area; and the two-sided partition plates are movably connected. The portable type uniformly-cooling first-aid medicine refrigerator disclosed by the invention has a simple structure, is convenient to carry and is suitable for extensive popularization.

The invention discloses an automatic type lifting door mechanism. The automatic type lifting door mechanism comprises a supporting plate, a first steel wire, a second steel wire and a firs slide door,wherein the top of the supporting plate is equipped with a first fixed pulley and a fourth fixed pulley; the bottom of the supporting plate is equipped with a second fixed pulley and a third fixed pulley; the supporting plate is equipped with a gas cylinder; the piston rod end of the gas cylinder is fixedly connected to a movable slide wheel; the head end of the first steel wire is connected to the top of the supporting plate; the first steel wire winds across the movable pulley and the first fixed pulley in sequence, and is fixedly connected to the top end of one side of the first slide door; the head end of the second steel wire is connected to the bottom end of the first slide door; the second steel wire winds across the second fixed pulley, the third fixed pulley and the fourth fixedpulley in sequence, and is fixedly connected to the top end of the other side of the first slide door; while the gas cylinder drives the movable slide wheel to move in a height direction of the supporting plate, the first steel wire and the second steel wire drive the first slid door to move in a height direction of the supporting plate. The automatic type lifting door mechanism avoids asynchronism of dual-gas-cylinder drive, so that two steel wires are not stranded together mutually.

The invention discloses a shearing machine capable of being fast adjusted. The shearing machine comprises a support, a shearing platform is arranged on the surface of the support, two guiding and fixing frames are arranged on the left side and the right side of the shearing platform, and guide grooves are formed in the two guiding and fixing frames. The two guide grooves are oppositely formed, a lifting plate is arranged in the two guide grooves, an upper cutter is arranged on the portion, between the two guiding and fixing frames, of the bottom of the lifting plate, and the upper cutter and the front side face of the cutting platform are used in cooperation for cutting. The portions, located on the two sides of the upper cutter, of the bottom of the lifting plate are connected with cam lifting mechanisms, the cam lifting mechanisms are arranged on a rotary shaft, the rotary shaft is connected with a power mechanism, a boss is further arranged on the rear side of the cutting platform, and the boss is sleeved with a locating sleeve. The shearing machine is small in size, stable in operating, high in cutting speed and high in efficiency.

The invention relates to a method for producing a smoking product from a tobacco material, wherein the tobacco material is treated using at least one extrusion process, which comprises compaction with an increase in pressure and temperature and a mechanical treatment and sudden flash drying of the material at an outlet of an extruder (1), wherein a heated process fluid (7) is supplied as a heat transfer medium to the tobacco material in the extruder (1) to supply process heat. The invention further relates to a device for producing a smoking product from a tobacco material using an extruder (1) which performs a compaction of a tobacco material with an increase in pressure and temperature and a mechanical treatment and sudden flash drying of the material at the extruder outlet, wherein the extruder (1) is associated with a heater (11), which heats a process fluid (7) that is supplied to the extruder (1) for supplying process heat as a heat transfer medium.

The invention provides a low-smoke halogen-free cable three-layer co-extrusion machine head which comprises a machine frame and a machine shell, a conical through hole is formed in the machine shell, a middle-layer feeding port and an inner-layer feeding port are formed in the side wall of the machine shell, an outer die head is connected to the end, penetrating out of a conductor, of the machine shell, an outer-layer die and a forming cavity are inserted into the outer die head, an outer-layer feeding port is formed in the outer circle side of the outer die head, and an inner-layer feeding port is formed in the outer circle side of the outer die head. A middle-layer mold and an inner-layer mold are sequentially inserted in the machine shell, an outer-layer mold is arranged, an outer-layer runner, a middle-layer runner and an inner-layer runner are arranged on the outer sides of the middle-layer mold and the inner-layer mold respectively, and an annular outer-layer discharging port, a middle-layer discharging port and an inner-layer discharging port which are communicated with the forming cavity are formed in the ends, close to the forming cavity, of the outer-layer mold and the inner-layer mold respectively. The outer-layer feed port is communicated with the outer-layer discharge port through an outer-layer runner, the middle-layer feed port is communicated with the middle-layer discharge port through a middle-layer runner, and the inner-layer feed port and the outer-layer feed port are communicated with the inner-layer discharge port through an inner-layer runner.
