紋孔道 的英文怎麼說
中文拼音 [wénkǒngdào]
紋孔道
英文
pit canal-
The relationship between capacitance and corrosion conditions in the enlargement of tunnels justifies the latter competition mechanism the varied etching conditions were implemented by enhancing the passivating characteristics and viscosity, changing the a13 + concentration, temperature of etchants and current pulsation. passivating acid in the etchant is conducive to the instant passivation of exposed areas on the foil surface, and hence sustains the balance of competition between aggressive anions and passivators, providing pit nucleatiori sites continuously
通過侵蝕液中添加草酸、硫酸、乙二醇，改變侵蝕液al ~ （ 3 + ）濃度和電流紋波等方法，研究了不同的侵蝕條件對隧道孔形貌和比容的影響，結果表明：草酸和硫酸既保護了鋁箔表面又促進了隧道孔孔壁的迅速鈍化，增加發孔密度。Road vehicles - hydraulic braking systems - double - flare pipes, tapped holes, male fittings and tube seats
