The present disclosure relates to a method of synthesizing cyclosporine derivatives. The method includes: providing a precursor fluid of the cyclosporine derivative, an alkaline fluid and a ClCHOCOCl solution; premixing the precursor fluid and the alkaline fluid to obtain a premixed solution; feeding the premixed solution into a first reaction chamber, reacting to prepare a first reaction liquid; feeding the first reaction liquid into a second reaction chamber, reacting the first reaction liquid with a COfluid to prepare a second reaction liquid; and reacting the second reaction liquid with the ClCHOCOCl solution.

Synthesis method of cyclosporine derivatives

An embodiment of the present invention relates to a network access method, system and terminal device, and computer storage medium, the method comprising: providing one or more physical network interfaces on a first terminal device; the first terminal device transmits an address resolution protocol (ARP) request to a second terminal device, the second terminal device being connected to the first terminal device via one of the physical network interfaces; if the first terminal device receives a DHCP discovery packet or a router announcement request within a first pre-set time, then the first terminal device accesses an internal network; if the first terminal device receives a router announcement broadcast within the first pre-set time or did not receive a response within the first preset time, then the first terminal device accesses an external network.
