Abstract: Embodiments of this application provide example holographic recording media, holographic polymer materials, methods for preparing holographic polymer materials, and display devices. An example holographic recording medium includes a first-order crosslinked network, a photoinitiator, and a second-order monomer. The first-order crosslinked network provides a mechanical support for the holographic recording medium. The second-order monomer includes a monomer with a free radical reactivity. The photoinitiator is used to initiate polymerization of the second-order monomer. The holographic recording medium includes at least one of an ester group (I), a urethane group (II), a carbamido group (III), an allophanate group (IV), or an amide group (V). Groups linked to the ester group (I), the urethane group (II), the carbamido group (III), the allophanate group (IV), and the amide group (V) are separately selected from at least one of the following: alkyl, alkoxy, alkenyl, or aryl.

Abstract: Provided are a storage system boot method and apparatus, and a computer-readable storage medium. The method includes: determining a configuration space by a bridge device; during booting a Basic Input Output System, after an initialization of a Peripheral Component Interconnect Express (PCIe) device is detected, determining, by connection information read from the configuration space, whether the preset hardware device is connected; if YES, continuing booting until finished; if NO, sending a reconnection instruction to stabilize a speed of a PCIe hardware link; when a number of the reconnection instruction sent is greater than a first preset value and the preset hardware device fails to be connected, sending a system reboot instruction; and when the number is less than the first preset value, continuing to determine whether the preset hardware device is connected after waiting for a preset duration.
