[Background]Gratings have been widely used in many important fields such as spectral analysis, national defense science and industry, and smart wear. With the progress and development of science and technology, new optical instruments put forward higher and higher requirements for the performance of

[Background]As a super thermal insulation material, SiO2 airgel composites are widely used in the fields of aerospace and national defense. Due to its soft and brittle mechanical properties, its high-quality processing has great challenges. Ultrasonic straight-edged cutting uses a sharp straight-edg

[Background]Short metal microfibers refer to metal microfibers with an aspect ratio of less than 100, which are widely used in industrial fields such as composite materials, filters, and flexible electronics due to their excellent thermoelectric properties. However, the existing processing met

【Background】Augmented assembly is an emerging intelligent assembly method, which mainly uses AR equipment to superimpose various forms of virtual information at specific positions in real space, thereby assisting the assembly process. According to previous studies, an enhanced assembly system can

【background】The surface roughness, surface oxide layer and its uniformity of the sinusoidal modulation target seriously affect the Rayleigh-Taylor instability and the neutron yield, particle penetration, hydrogenation reaction and other related nuclear reaction performance in the particle microspr
