Hence, it is quite different from the general integrity of the intangible cultural heritage protection. However, as one form of protection of intangible cultural heritage, it is connected with other forms of protection. Based on the cultural integration, the paper studied and summarized domain of intangible cultural heritage, and further research and investigation of the Eco-cultural preservation areas are discussed.展开更多

After the lightning rod is installed at a certain height on the ground,the lightning rod tip reaches the corona threshold to ionize the surrounding air and generate positive and negative ions under the action of the electric field at the end of the lightning downward leader. Constrained by Coulomb’s Law,its positive ions( opposite charges attract each other) form an upward leader( streamer),which moves towards the end of the lightning downward leader and is connected to the downward leader,establishing a discharge channel to attract lightning to the needle tip and discharge the current to the ground,and playing a role in attracting lightning. Its negative ions are repelled by the electric field at the end of the lightning downward leader( repelled by isotropic charges) and influenced by the wind,and diffuse in the downwind area to form an ion cloud,inhibiting the growth of corona at the tip of ground objects,and playing a role in shielding lightning. In this paper,Franklin’s understanding of the role of lightning rod and Yang Shaojie’s new definition of the working principle of lightning rod are briefly introduced. The formation mechanism,distribution characteristics,shielding effect,and impact on lightning strike point distribution of ion clouds are analyzed. Additionally,the important role of shielding effects of ion clouds in regional lightning protection is introduced,which provides a theoretical basis for the correct understanding and use of lightning rod.展开更多

In the context of the integrated development of agriculture, tourism, and cultural industries, this paper integrates the thinking of "immersive theatre" and adopts the design method of multithread dramatic narrative mode to create a number of interactive flow lines in the architecture and focus on the sensory experiences of environment, enabling the traditional regional culture to really touch the audience.展开更多
