Well, I find the solution is actually using Python extension solely, without Jupyter.

What version of python are you using?
What version of Jupyter are you using?
Please upload contents of your user and workspace settings.json file.

There were nothing related to python or jupyter in my user settings.json file. And I didn't use a workspace settings.json file. The content in user settings.json is shown as follows:

// Place your settings in this file to overwrite the default settings
{
    "editor.fontFamily": "Consolas, microsoft yahei",

    "files.associations": {
        "*.m": "matlab"
    },

    "editor.wordWrap": "on",

    // "terminal.integrated.shell.windows": "C:\\WINDOWS\\Sysnative\\bash.exe",

    // Port number to use for connection.
    "remote.port": 52698,

    // Launch the server on start up.
    "remote.onstartup": true
}

When I click "run cell" link in vs code,it prompts “start a new notebook or select an existing notebook”. If i click the "start a new notebook" link,the Cpu occupancy rate will reach 99%, and start a lot of python threads!
