A system for removing dust from exhaust gas, comprising a dust removing system inlet, a dust removing system outlet, and an electric field apparatus (1021). The electric field apparatus (1021) comprises an electric field apparatus inlet, an electric field apparatus outlet, a dust-removing electric field cathode (10212) and a dust-removing electric field anode (10211). The dust-removing electric field cathode (10212) and the dust-removing electric field anode (10211) are used to generate an ionizing electric field for dust removal. When a certain amount of dust has accumulated on the electric field apparatus, the electric field apparatus performs a black carbon removal process, thereby avoiding a reduced electrode gap resulting from an increased thickness of black carbon.

This invention relates to the field of lithography and particularly to a lithographic method, a lithographic product and a lithographic material. The invention provides a lithographic method including the steps of: 1) providing first light and second light to the lithographic material, wherein at least part of molecules for generating effector molecules controllable by a molecular switch in a turned-on state generate effector molecules, thereby changing physical and/or chemical properties of the lithographic material in an area where the molecular switch is turned on; and 2) removing either the lithographic material that has changed in physical or chemical properties or the lithographic material that has not changed. The novel lithographic method provided by the invention can effectively break through the diffraction limit of light, thereby further improving lithography precision.
