Disclosed are an arc extinguishing control system and method for a relay of an emergency power supply. A relay serves as a main switching circuit for controlling an emergency power supply, and electronic switching tubes are connected in parallel to two ends of the relay, so as to withstand a voltage jump when the relay is disconnected, and common problems of existing relays, such as arc damage and an internal resistance increase, are solved. When a heavy reverse charging current occurs after the vehicle is started, a reverse charging sensing circuit and a reverse charging feedback circuit are used, so that a reverse charging current is directly fed back to a control end of an electronic switching tube when a storage battery is reversely charged by a load, thereby realizing quick disconnection of the electronic switching tube.

A multi-target kinase inhibitor is shown in formula (I), in which R is selected from formula (a), formula (b), formula (c), formula (d), formula (e) and formula (f). The multi-target kinase inhibitor can effectively inhibit the enzymatic activities of RET, VEGFR3 and PDGFRA, and can effectively treat diseases that are regulated and controlled by multi-target kinases and are related to abnormal signal transduction pathways of the multi-target kinases, including cancers of breast, respiratory tract, brain, reproductive organ, digestive tract, urinary tract, eye, liver, skin, head and/or neck and distant metastatic cancers thereof, and lymphoma, sarcoma, leukemia and the like. The active ingredients of the pharmaceutical composition of the present invention comprise a multi-target kinase inhibitor, which accounts for 1-50 wt % of the composition.
