reversal of polarization-
For electrodeposition by dc methods, the metals deposite uninterrupted and the particles were also embeded uninterrupted into the coatings ; for electrodeposition by pc method, the particles with biggish volume were desorbed from the coatings and returned to the electrolyte again owing to the presence of pulse interval ; for electrodeposition by prc method, the particles carried positive charges are much more easy to desorb from the coatings owing to the effecf of reverse pulse current combined with pulse interval, in addition, the reverse pulse current also could dissovle the metals, further accelerates the desorption of particles, thus the particles size embeded in the coatings by prc method is the least
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。In spite of their unitarian proclivities and their masks of conservative broadmindedness, they were two generations behind interpretative science : their mental processes were mediaeval, while their thinking on the ultimate data of existence and of the universe struck him as the same metaphysical method that was as young as the youngest race, as old as the cave - man, and older - the same that moved the first pleistocene ape - man to fear the dark ; that moved the first hasty hebrew savage to incarnate eve from adam s rib ; that moved descartes to build an idealistic system of the universe out of the projections of his own puny ego ; and that moved the famous british ecclesiastic to denounce evolution in satire so scathing as to win immediate applause and leave his name a notorious scrawl on the page of history
