Abstract: A method for preparing a large-scale two-dimensional single crystal material stack which has an interlayer rotation angle. Single crystal substrates are stacked and rotated at a specific angle, a two-dimensional single crystal material is epitaxial on the surface thereof, and then an upper layer and a lower layer of the two-dimensional single crystal material are attached, and a layer of the single crystal substrates on the surface is removed so as to obtain a two-dimensional single crystal stack which has a specific rotation angle. A large-scale two-dimensional single crystal material stack which has an interlayer rotation angle prepared by the described method.

Abstract: The present disclosure relates to a network technology, and discloses a method, a device and a server for processing an access request. The method comprises: obtaining a response content corresponding to the access request from a source station according to a URL of the access request, when receiving the access request sent by a client terminal; adjusting domain names of at least two sub-resource requests in response content to be a same domain name of a preset protocol type, and returning adjusted response content to the client terminal; restoring, when receiving a sub-resource request having the same domain name, the domain name of the sub-resource request to an original domain name thereof; and obtaining a sub-resource content corresponding to the sub-resource request from the source station according to the original domain name of the sub-resource request, and returning the sub-resource content to the client terminal.
