108 results about "String group" patented technology

In topology, a branch of mathematics, a string group is an infinite-dimensional group String(n) introduced by Stolz (1996) as a 3-connected cover of a spin group. A string manifold is a manifold with a lifting of its frame bundle to a string group bundle. This means that in addition to being able to define holonomy along paths, one can also define holonomies for surfaces going between strings. There is a short exact sequence of topological groups 0→K(Z,2)→String(n)→Spin(n)→0 where K(Z, 2) is an Eilenberg–MacLane space and Spin(n) is a spin group.

Solar cell string automatic superposition welding machine

A solar cell string automatic superposition welding machine is disclosed and comprises a machine rack, a front end confluence belt supply device, a tail end confluence belt supply device, a front end confluence belt welding device, a tail end confluence belt welding device, an insulating film supply device and a cell string group bearing plate, wherein the front end confluence belt supply device is used for cutting born confluence belts and folding each of cut confluence welding belts into an L shape, the insulating film supply device is used for cutting born insulating film belts and obtaining insulating film strips, the bent confluence welding belts are placed on front ends of interconnecting belts of cell strings on the cell string group bearing plate via the front end confluence belt welding device, and therefore welding operation can be conducted; the insulating film strips are placed on the bent confluence welding belts via the front end confluence belt welding device, and therefore the bent confluence welding belts can be insulated from each other; the tail end confluence belt supply device and the tail end confluence belt welding device are used for fixing interconnecting belts of rear ends of the cell strings onto the confluence welding belts in a cooperating manner, and therefore the cell strings can be connected in series. No manual welding operation is required, and the confluence belts can be welded onto the interconnecting belts in a high quality manner.

Method and system for rapidly inputting bulk information

The invention relates to a method and a system for rapidly inputting bulk information, belonging to the field of computer word information input. The method comprises the following steps: 1. obtaining a Chinese character or Chinese character string group to be matched; 2. matching each Chinese character or Chinese character string in the obtained Chinese character or Chinese character string group to be matched with a Chinese character or Chinese character string predefined by a user in a preset matching table; if the Chinese characters or the Chinese character strings are matched, obtaining a replacing content corresponding to the matched Chinese character or the Chinese character strings, and the preset matching table is used for recording and storing the Chinese characters or Chinese character strings predefined by the user and the corresponding replacing contents; and 3. outputting and displaying the replacing contents. The invention outputs and displays the replacing contents by comparing each Chinese character or Chinese character string in the Chinese character or Chinese character string group to be matched with the Chinese characters or Chinese character strings predefined by the user in the preset matching table, effectively lightens the memory load of the user, improves the input efficiency of the user, and the like.

Solar battery assembly and preparation method thereof

The invention discloses a solar battery assembly comprising a cover plate material, an EVA and/or POE material, a battery string group, an EVA and/or POE material, and a backboard material. The battery string group is formed by series connection of a plurality of battery strings; each battery string is formed by series connection of a plurality of battery pieces; and conducting materials are arranged at front-side electrodes and/or back-side electrodes of all battery pieces locally or completely, wherein the conducting materials are metal coating or solid conducting resin; and the front-side electrode of one of each two adjacent battery pieces and the back-side electrode of the other battery piece are connected in series by the metal coating or solid conducting resin. According to the solar battery assembly, an interconnect material is applied to a battery end directly, so that usage of a solder strip or other conducting materials is reduced directly; the production efficiency of the same kind of assembly is improved; the internal resistance losses caused by the interconnect strip are reduced effectively; and the assembly power is improved and thus the power generation cost is lowered. In addition, the invention also discloses a preparation method of the solar battery assembly.
