Abstract: A double-sided polishing method for an optical lens belongs to the technical field of ultra-precision machining. In the double-sided polishing method, upper and lower surfaces of the lens are polished simultaneously by arranging abrasive tools on upper and lower positions of the lens, making the abrasive tools close to the upper and lower surfaces of the lens to swing back and forth in the polishing process, producing relative motion and removing the surface materials. In the present invention, in order to eliminate a problem of removal ununiformity, a method for swing machining of abrasive tools and methods for turning over and polishing of workpieces are adopted in a polishing process, which can realize the high efficiency double-sided high-precision machining for a nonplanar lens, and the method can be applied to the double-sided polishing for different types of lenses.

Abstract: A separation and purification coupled process with a high helium yield and diversified products is provided. The process is as follows. Firstly, a low-concentration helium-containing gas after being pressurized and pre-treated enters a two-stage and two-section membrane separation unit to produce a helium product with a medium concentration by concentrating stage by stage through the membrane separation unit. A part of the helium with medium concentration enters an adsorption unit for further concentration to produce a helium product above grade A.

Abstract: The present disclosure relates to the technical field of dissimilar welding of Cu and a steel, and in particular to a welding wire for dissimilar welding of Cu and a steel and a preparation method thereof and a method for welding Cu and a steel. The present disclosure provides a welding wire for dissimilar welding of Cu and a steel, including, in percentages by mass, 5-25% of iron phase, less than 0.1% of inevitable impurities, and copper matrix. The welding wire of the present disclosure, containing two elements, i.e. copper and iron, is conducive to the mixing of the two phases—copper and iron—during the welding process, to form a mutual soluble region, thereby makes it possible to greatly increase the weldability, reduce the width of the weld, effectively overcome the tendency of cracks, and thus to ensure the formed weld with a high crack resistance.
