直流電沉積時，基質金屬的沉積連續進行，粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附，重新回到溶液中;採用周期換向脈沖時，反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附，同時，反向脈沖電流對基質金屬的溶解作用，也會促進粒子的脫附，因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加，三種鍍層的晶粒都明顯細化，說明al _ 2o _ 3的存在阻止了晶粒的長大，提高了電沉積過程中晶核的形成速率。Bloom s bodyguard distribute maundy money, commemoration medals, loaves and fishes, temperance badges, expensive henry clay cigars, free cowbones for soup, rubber preservatives, in sealed envelopes tied with gold thread, butter scotch, pineapple rock, billets doux in the form of cocked hats, readymade suits, porringers of toad in the hole, bottles of jeyes fluid, purchase stamps, 40 days indulgences, spurious coins, dairyfed pork sausages, theatre passes, season tickets available for all tram lines, coupons of the royal and privileged hungarian lottery, penny dinner counters, cheap reprints of the world s twelve worst books : froggy and fritz politic, care of the baby infantilic, so meals for 7 6 culinic, was jesus a sun myth

將液體火箭發動機燃燒室的冷卻通道設計為斜航線（等傾角螺旋線）槽形，可以大幅度改善燃燒室的冷卻性能.斜航線冷卻槽的槽寬尺寸較小而槽深尺寸較大，所以無法使用棒銑刀銑削、電化學等加工方式.針對這些特點，提出了五軸控制、四軸聯動的數控片銑刀銑削加工方法.由於燃燒室外表面的母線輪廓復雜，手工編制數控加工程序難度大.為了解決數控加工程序的編制問題，研究了斜航線的數學模型，開發了自動編程軟體系統.使用該系統，可以生成多種母線輪廓回轉體外表面上的斜航線數控加工程序.燃燒室收斂-擴張段的母線斜率變化大，加工難度大，是斜航線冷卻通道加工的最典型工件.經過理論分析和實際切削實驗，研究了針對該類型工件的片銑刀直徑選擇、銑削方式和方向、刀具調整和起刀點的設置等多項實際的加工方案.採用上述的一系列技術，已經成功地加工了數十個合格工件.經過兩年多的實際生產過程應用，驗證了所開發的斜航線冷卻通道加工方法的正確性和可行性.這些加工技術的研製成功，對其他相似類型零件的加工亦具有參考意義Liberation of hydrogen gas would be increased rapidly and sic particles on the surface might be dispersed if the current density exceed the upper limit. furthermore, nickelous hydroxide would be deposited because the ph of plating solution nearby the surface rapidly increased. all of above might result in coating deterioration
