Abstract: The present invention relates to a covalent organic framework which is a two-dimensional polymer formed by repeatedly arranging structural units represented by formula I or formula II and bonding same by means of covalent bonds. The present invention also relates to a catalyst, preparation methods for the covalent organic framework and the catalyst, and applications of the covalent organic framework and the catalyst in catalyzing olefin polymerization. The covalent organic framework can be used as a support to control the stereoregular polymerization of olefins in a confined space. The catalyst has high catalytic activity and good high-temperature stability, and widens the range of types of olefin polymerization catalysts.

Abstract: The present invention relates to a method for preparing a hollow covalent organic framework (COF) material and hollow COF material prepared by said method. Said method is characterized in including a monomer displacement step in the method, thereby obtaining the hollow COF material with a controllable particle size, wall thickness and/or specific surface area.

Abstract: A method for preparing a supported olefin polymerization catalyst, comprising: step 1, activating a COF at 0° C.-800° C. for 0.1-48 hours under inert atmosphere or vacuum protection; optionally, step 2, reacting the activated COF with an auxiliary agent in a reaction medium at a temperature of 5° C.-120° C. under inert atmosphere or vacuum protection, and performing solid-liquid separation to obtain a solid phase material, wherein the auxiliary agent is selected from a metal alkyl compound, boron halothane, an alkyl aluminum oxide, a modified methyl aluminoxane, a Lewis acid, and a Grignard reagent; and step 3, under inert atmosphere or vacuum protection, reacting the solid phase material with the olefin polymerization catalyst in a reaction medium at ?30° C.-150° C., performing solid-liquid separation, and collecting the solid phase material as the supported olefin polymerization catalyst. A supported olefin polymerization catalyst and an application thereof.

Abstract: The present invention provides a method and system for loading and running program images rapidly in a multi-processor system. The method comprises the steps of: starting in a synergistic processor a synergistic processing program listener, which is configured to listen to a notification from a main processor; calling in the main processor a run-synergistic-processing-program function which is configured to notify the synergistic processing program listener to run a synergistic processing program image which is part of the program image and has been transferred to the local store of the synergistic processor; and the synergistic processing program listener running the synergistic processing program image in response to receiving the notification.

Abstract: The present invention provides techniques for performing molecular dynamics simulation on a multiprocessor system. The method comprises: dividing a substance space on which molecular dynamics simulation are to be performed into a plurality of cells; storing data of molecules of the plurality of cells in the main memory of the multiprocessor system such that data of molecules of each cell are continuously stored in a memory area corresponding to the cell; and the plurality of accelerators repeatedly acquiring the data of molecules of the plurality of cells from the main memory and performing molecular dynamics simulation computations in parallel such that data of molecules of at least one cell are acquired in one DMA operation. By continuously storing data of molecules of each cell in a memory area corresponding to the cell, the present invention reduces the data exchanges between each accelerator and the main memory during simulation.
