The invention provides a platy heat pipe, comprising a platy heat pipe frame, wherein the platy heat pipe frame is internally provided with a microporous pipe trunk structure which is formed by a group of microporous pipes, side walls of the microporous pipes are connected to mutually enhance the strength of each microporous pipe, each microporous pipe is filled with a working medium with a phase inversion heat exchange effect, two ends of the platy heat pipe are sealed, and at least one end is provided with a gradually contractive sealing belt formed by cold welding. The platy heat pipe provided by the invention has the characteristics of high strength, super thinness, high efficiency and high heat transportation volume and can substitute an oscillation heat pipe and a common heat pipe.

The present invention is to authenticate the user on the basis of an identifier and authentication information which are provided from a portable terminal and service server to a user terminal and displayed. Accordingly, an external invader cannot perform authentication instead of the user unless the external invader collects information required for authentication from all of the portable terminal, the service server, and the user terminal at the same time. The present invention can be used for processing authentication in portal sites, banking facilities including banks, personal blogs, homepages, and various other websites using the Internet.

The invention discloses a process and a device for generating power by pressure energy of a small natural gas pipeline network. A high-pressure pipeline network of the device is connected with a gas inlet of an expansion machine through a pipeline; a gas outlet of the expansion machine is connected with a gas inlet of a temperature balancer through a pipeline; an outlet of the temperature balancer is connected with a low and medium-pressure gas pipeline network through a pipeline; a main shaft of the expansion machine is connected with a gearbox; the gearbox is connected with a power generator; the power generator is connected with a transformer synchronizer; the expansion machine adopts an improved AT15-65 type gas expansion machine; one end of the main shaft is connected with an air cylinder in a totally-closed way; a first seal ring and a second seal ring, which have sealing effects, are arranged between the other end of the main shaft and a wheel drum; a flow guide pipe is arranged in a closed cavity between the two seal rings; the flow guide pipe is connected with an inert gas bottle. The device can be used for continuously and stably providing a 220 V / 380 V stable power supply for an interruptible and closed 1-5 kW low-power user.

The invention discloses a high-protection-level air-cooled lithium battery pack thermal management system and method. The system comprises one or more layers of batteries and / or battery modules in thebattery pack, a battery pack shell and an external air cooling module, wherein the battery and / or the upper surface and / or the lower surface are / is attached to a micro heat pipe array, the part attached to the surface of the battery and / or the battery module is an evaporation section, at least one end of the micro heat pipe array extends out of the surface of the battery and / or the battery module, and the extending part serves as a condensation section to be attached to a battery pack shell; the battery pack shell surrounds the battery pack and is of a closed structure, and at least the position, corresponding to the condensation section, of the battery pack shell is provided with a heat conduction partition plate; the external air cooling module is tightly attached to the outer surface of the face, provided with the heat conduction partition plate, of the battery pack shell, air cooling fins are arranged in the external air cooling module, and a fan is arranged on the side face of the external air cooling module. The heat dissipation efficiency is high, the risk of liquid pollution is avoided, and the protection level is high.

The invention relates to an identity-based anonymous authentication method and system. The method comprises the following steps: a server generates two partial private keys and sends the same to double parties P1 and P2 participating in the authentication respectively, wherein P1 and P2 generate a main authentication code (the formula is described in the specification) and R in an authentication process, and the privacy and reliability of the interactive information between P1 and P2 are ensured by using zero knowledge proof; after the P1 obtains the main authentication code, the P1 generatesa pseudo-address AID, generates a third temporary public key R3, calculates a final authentication code alpha, and sends the authentication information (AID, R, R3, alpha, T) the server, and the server verifies the authentication information and feeds back the authentication information to a user, after the successful completion of three times of handshake, the server can establish secure communication with the user. The identity-based anonymous authentication method and system are suitable for jointly completing identity-based distributed anonymous authentication without exposing the respective partial authentication private keys of the both parties together, the both parties holding the partial private keys must participate in the authentication at the same time, and the complete authentication private key does not need to be restored.

The invention provides an independent B-type LNG ship liquid cargo tank heat insulation system with a splash-proof screen structure. The independent B-type LNG ship liquid cargo tank heat insulation system comprises a splash-proof screen, a bolt mechanism and a heat insulation plate, wherein the splash-proof screen is arranged on a main screen wall in a spaced manner through a supporting mechanism; the bolt mechanism is arranged on the main screen wall; and the heat insulation plate is fixed to the splash-proof screen through the bolt mechanism. The independent B-type LNG ship liquid cargo tank heat insulation system has the beneficial effects that all components are subject to modularization manufacturing and installation, unified standard specifications can be adopted when the components are prefabricated, and the working amount and the cost of manufacturing are reduced; heat insulation plate modules are relatively independent, when some module is damaged, the other modules cannot be influenced, and the reliability of heat insulation layers is improved; in addition, when the damaged module is repaired, only one damaged module needs to be dismounted for local repairing, and convenience is brought to maintenance and repairing; and the heat insulation system is suitable for an independent B-type LNG ship liquid cargo tank, can also be used for other shore-based low-temperature liquid cargo storage tanks or can serve as a heat insulation system of other low-temperature occasions.
