As an important carrier of culture and education, digital exhibitions are a powerful supplement to physical museum exhibitions, which determine the key role and unique mission they play in the process of knowledge dissemination. Applying virtual reality technology to digital museums has great potential to improve the content development of online exhibitions and engage target visitors. In this article, the work focus and the main issues of development background, and the technical solutions and applied cases of VR exhibitions are analyzed to carry out the prospect of application with development suggestions. The key research area of VR exhibitions has 3 main focuses in the next stage of development: integrating visitor studies and VR technology; combining narrative curation with VR technology; designing visitors'participatory as a curation element through VR technology. The 3 aspects above combined contributing to the iterative optimization of communication effect will ultimately help the service upgrade of museum.

Stone artifacts can be seen as an important component of cultural heritage. A large portion of them is directly exposed to the natural environment, so their weathering process has long been a focus in academia. This paper summarizes the relevant experimental literature in the past ten years, analyzes and evaluates the experimental methods of artificial weathering of stone artifacts and the detection technology of their weathering effect. Artificial aging test of stone artificials refers to that researchers apply dry and wet cycling, salt crystallization, thermal stress and freeze-thaw weathering in laboratory to simulate outdoor environment, and use physical and chemical methods, such as infrared thermal wave imaging, rock medium ultrasound, nuclear magnetic resonance, and other technologies, to study the degradation mechanism, degree, and manifestation of stone artifacts. At the same time, by studying their texture structure, composition, porosity, thermal conductivity and other information, the weathering degree of the stone can be quantified. These works provide us with a theoretical foundation to understand the weathering mechanism of stone and help us protect stone artifacts in the future. It will help make the protection of cultural relics more scientific and effective, and provide strong support for the protection of precious cultural heritage.
