  2. From 1996 to 1998, as a project manager, i finished the studies on simple constructed venturi water film scrubber desulphurization technology and equipment for small and medium _ sized coal _ fired power plant. such studies are one of the projects required to rack one ' s brain with emphasis by ministry of science and technology in " ninth _ five _ year " plan. on the basis of the aboved researches, being entrusted with jiangxi provencial electric power bureau and guizhou provincial electric power bureau, we conducted the engineering feasible researches and preliminary design for nanchang power power plant and guixi power plant in jiangxi province, guiyang power plant in guizhou province, yongji power plant and taiyuan thermal power plant no. 2 in shanxi province to use venturi water film scrubber simple constructed desulphurization technology. the major technical targets of above consultation are around 70 % of desulphurization rate and improved dust removal efficiencies comparing with original efficiencies. the key features of this new technology are advanced and practical, low in investment cost, small in land occupied, suit for renovating the existing power plant and suited to chinese conditions

    1998年完成了"九.五"國家科技攻關項目< >的開發工作.在此基礎上,貴州省電力局,江西省電力局,山西省電力局的委託,分別對貴陽發電廠,南昌發電廠,貴溪發電廠,永濟發電廠,太原第二電廠等進行了簡易脫硫技術的工程可行性研究以及初步設計等.上述咨詢內容中的主要技術指標是脫硫率達到70 %左右,並可提高原除塵器的除塵率.投資低,佔地積小,適合老廠改造,技術先進實用等特點
  3. This dissertation focuses on how to develop a high performance damping mechanism based on multi - energy transitions, which is independent or little dependant with the viscoelasticity of polymer matrix. three sections are mainly included in this dissertation as follows : chlorinated polyethylene ( cpe ) / piezoelectric ceramic ( pzt ) / vapor grown carbon fiber ( vgcf ) composites ; cpe / 2, 2 ' - methylene - bis - ( 4 - methyl - 6 - cyclohexylphenol ) ( zkf ) / vgcf composites ; organic hybrids made from cpe and small molecules cpe / pzt / vgcf composites : the damping composites of multi - energy transitions mechanism were produced by mixing pzt and vgcf into cpe. in this system, the mechanical vibration energy that was transmitted to cpe was found to convert into joule ' s heat through conduction paths between vgcf in the polymer matrix, so the vibration fades away

    本論文主要包括三個方的研究內容: ?氯化聚乙烯( cpe ) /壓電陶瓷( pzt ) /氣相生長碳纖維( vgcf )復合材料; ? cpe /雙[ ( 2 -羥基- 3 -環己基- 5 -甲基) -苯基]甲烷( zkf ) / vgcf復合材料; ? cpe基機小分子混雜型復合材料cpe / pzt / vgcf減振復合材料:利用壓電和導電填料填充高聚物基體,當復合材料到機械振動時,通過高聚物基體將機械振動能傳遞到壓電陶瓷粒子上,利用壓電陶瓷的壓電應,將機械能轉換成電能,則電流在導電粒子產生的迴路中流動,由於導電迴路具一定的電阻,所以電能又轉變成能耗散掉,從而起到減振的目的。
  4. The immersion electrical heater is chiefly applied in the direct contact mode of fluid heating. it features fast heat exchange and high thermal efficiency. it has the varieties of water heater, oil heater and gas heater. its heating element power density, i. e. the power per unit of heating area of the heating element, is an important parameter of the electrical heating element, which has a direct bearing on the performance and working life. the working out of the value is a highly specialized problem, being under the influence of many factors ( media flow rate, tempt, physical and chemical properties and direction in which the medium flows past the element etc )
