ecac 解釋
歐洲民航會議
  1. Piezoresistivity of ecac may involve proximity effect, microcrack and the staggered arrangements of conductive pass - ways due to shear strength of aggregates

    壓敏產生的原因是導電瀝青混凝土試件的壓縮鄰近效應、微裂紋和石料間的剪切力使部分導電通路錯位。
  2. Experimental results of marshall remnant stability test, water susceptibility tensile strength ratio ( tsr ) test and rutting test show that graphite modified ecac possesses of high anti - water damage ability and excellent high - temperature stability, which is expected to apply as new - type pavement

    馬歇爾殘留穩定度試驗、凍融劈裂試驗和車轍試驗表明石墨導電瀝青混凝土的抗水損害能力強，高溫穩定性能良好，可作為新型路面使用。
  3. Percolation theory can explain the formation of conductive passages under the dependence of the conductivity and graphite content in ecac

    導電瀝青混凝土中導電率與石墨摻量依賴性可用滲流理論解釋其導電通路的形成。
  4. Graphite absorbs asphalt in liquid state strongly. the evaluation of volume performance of ecac must take absorbed asphalt into account

    石墨對瀝青的吸收能力強，評價導電瀝青混凝土的體積性能指標必須考慮吸收瀝青。
  5. The absorbing oil nature of carbon black, the lubricated effect of graphite and the bad dispersion of carbon fiber limit their application in ecac respectively

    炭黑的吸油性、石墨的潤滑性及碳纖維的分散性分別限制其在導電瀝青混凝土的應用。
  6. There are several different kind of access control, including rbac ( role - based access control ), tbac ( task - based access control ) and ecac ( extended capacity access control )

    訪問控制的類型很多，如基於角色的訪問控制，基於任務的訪問控制，擴展權能訪問控制
  7. The improving effect of graphite on the resistivity of ecac is excellent, and the composite modification with other conductive materials also is obvious. graphite was used as main component, and a few carbon fibers were added as assistant component. carbon black replaced a par t of limestone powder, which has an enforcement effect on asphalt concrete

    石墨單位體積對瀝青混凝土導電性能改善效果良好，與其它導電相材料復合改性時改善作用顯著，可作為導電瀝青混凝土的主要導電相材料，少量碳纖維作為輔助導電相，同時炭黑代替部分礦粉既可起增強作用。
