The invention provides a method for cleaning a first mirror in situ through radio frequency plasma. The method is characterized in that a coaxial cable is adopted to introduce a radio-frequency power supply into a sample exchange chamber connected with a Tokamak device vacuum chamber, and the radio-frequency power supply is connected to the first mirror; the first mirror is pushed to the Tokamak device vacuum chamber through a sample conveying rod in the sample exchange chamber; the Tokamak device vacuum chamber is filled with a working gas, and the radio-frequency power supply is turned on to apply radio-frequency voltage to the first mirror; the radio-frequency power is gradually improved, a radio-frequency matcher is regulated to enable the radio-frequency reflection power to be zero, and the radio frequency plasma is generated on the surface of the first mirror; the self bias of the first mirror is regulated according to the category of surface deposition layers of the first mirror, and the surface deposition layers of the first mirror are cleaned through plasma sputtering; after cleaning for a certain time, the radio-frequency power supply is turned off and cleaning is stopped; and the first mirror sample is taken out through the sample exchange chamber and the sample conveying rod, and subsequent characterization is carried out.

The invention discloses a manufacture method and a manufacture device of a lapping isolated installation wire. The method comprises the following steps: 1) according to a preset width, splitting a plastic film for later use; 2) cleaning and processing a wire in an alcohol pool; 3) wrapping and covering the split plastic film on the periphery of the wire by a covering machine in an anti-static device to obtain blank; 4) directly sending the blank from the outlet of the covering machine to a high-temperature sintering device, and sintering the blank at high temperature to obtain a semi-finishedproduct; and 5) sending the semi-finished product to an assistant dust-proof device, and cooling and processing the semi-finished product to obtain a finished product. The manufacture device comprises the covering machine, the high-temperature sintering device, the alcohol pool and the anti-static device, wherein the alcohol pool, the covering machine, the high-temperature sintering device and the anti-static device are integrally arranged on a frame shell. According to the invention, dark spots on the lapping installation wire of the finished product can be effectively avoided and the quality of the lapping installation wire of the finished product is improved.

The invention discloses an antioxidant treatment method for isoprene rubber. The antioxidant treatment method comprises the following steps: (I) mixing an antioxidant 1076, an antioxidant 412S, an antioxidant 1010 and an antioxidant 38, crushing and uniformly stirring to obtain a powdered compound antioxidant; granulating the powdered compound antioxidant in a granulator, and carrying out particlefinishing to obtain a columnar granular compound antioxidant; (II) dissolving the columnar granular compound antioxidant obtained in the step (I) in a solvent, adding into polyisoprene rubber latex,separating colloidal particles by adopting a hot water condensation method, and dehydrating the colloidal particles. The method disclosed by the invention has the advantages of reasonable steps, scientific antioxidant formula and feasible operation; the polyisoprene rubber obtained by the method disclosed by the invention has better thermal stability and longer-time oxidation resistance.
