forward extraction
1.Abstract: The formation of traditional V extraction from coal stone isreviewed in Hunan Province.The paper described several currently applied new processes for V extraction from coal stone.Suggestions are put forward for further development of V extraction from the coal stone.
2.Through analysis,the following sugg estions is put forward:to build200MW and125MW class double-extraction s team tur-bines separately in the two power plants,completed with410t/h an d450t/h class circulating fluidized bed combustion(CFBC)boilers,the total evaporation capacity of boilers in two power plants will reach2540t/h.
3.For feature extraction, this dissertation studies Barnard algorithm for Edge Point extraction and SUSAN algorithm for Corner extraction, Afterward, I put forward a method to extract inflexions, straight lines and curves based on Freeman Differential Code. Thus the use of Freeman Code can be extended and there will be more approaches to finish stereo correspondence.
4.The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed, in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage, put forward the isolated section-grouting technology for overburden bed separation space, integrated the virtue of growing for bed separation space and partial extraction, the bed separation grouting bodies, key stratum and isolated section pillars were made to constitute the load-carrying body all together, and to reach the purpose of reducing subsidence effectively, increase the coal seam extraction ratio, and accelerate the development of isolated section-growing technology for overburden bed separation space.
5.The nutritive composition in sargassum from Haitian had been determined. The extraction of seaweed polysaccharides by hot water was studied. And the application prospect of seaweed polysaccharides was put forward.
6.And the techniques such as wide angle reflection information extraction, interacted dynamic NMO correction muting in CMP super-gather, are first brought forward in Jianghan Oilfield , and a proper seismic data processing flow is confirmed .
7.After summarizing the circumstance, this article analyse the advantage of information extraction using XML, bring forward a middle document format based on XML, which is mainly including the title, structure, information of text format, links, tables and some metadata of documents.
