The invention relates to a composite liquid armor based on pure silica nanoparticles derived from sea sand and its production method. In our invention, composite liquid armor can be utilized in both military and civilian defense industries. Alongside its durability, the armor offers high performance, enables ease of movement, and features a lightweight, free-particle modular structure. By providing a domestic alternative, it reduces dependency on foreign technologies in this field.

The invention provides an application system and an application method of a flight simulation training data packet, and belongs to the technical field of aviation simulation training. The system comprises a data acquisition module, an engineering data packet processing module, a training data packet generation module, an error verification module and an adaptive output module. According to the method, an engineering data packet is constructed by arranging aircraft design data and wind tunnel data, a training data packet meeting the standard of a CAAC full-motion D-level simulator is formed after flight experiment correction, and the error is controlled within 5%. The system realizes localization of flight simulation training data packets, breaks through foreign technical monopoly, guarantees national defense safety, improves training fidelity and economical efficiency, and can be widely applied to the field of civil aviation and military aircraft simulation training.

The invention belongs to the technical field of chip manufacturing, and discloses a collecting device for a chip manufacturing process, which comprises a shell and a collector positioned in the shell. According to the present invention, the first channel, the second channel, the third channel and the gas outlet pipe are arranged in the housing; a gas mixture enters the first channel, firstly diffuses all around to enter the second channel, flows downwards along the second channel, enters the third channel from the side wall of the lower end of the collector and the bottom of the collector, flows upwards in the third channel, enters the upper end of the gas outlet pipe, and finally flows downwards along the gas outlet pipe to be discharged; the flow path of the gas mixture is reasonable, the contact time of the gas mixture in the collecting device is long, and a good condensation collecting effect is achieved. According to the invention, the dependence on foreign imported equipment and parts is greatly reduced, the foreign technical monopoly is broken, and the production cost of chips in China is greatly reduced.
