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。Kitty ricketts, a bony pallid whore in navy costume, doeskin gloves rolled back from a coral wristlet, a chain purse in her hand, sits perched on the edge of the table swinging her leg and glancing at herself in the gilt mirror over the mantelpiece

摘要通過對收錄于《道藏》之中的《上清明鑒要經》和《洞玄靈寶道士明鏡法》兩部經書所記載的兩則磨鏡藥史料的考證分析,提出至晚在南北朝時期中國已經發明了用錫汞齊鍍鏡的技術,其技術很可能由方士或道士在煉制黃金白銀、金丹大藥的過程中或社會小范圍內發展起來的;在宋代之前,用錫汞齊磨鏡的技術僅僅在部分煉丹道士中應用流傳,宋之後由於道教外丹術的衰落,用錫汞齊磨鏡的技術流傳於民間。Caderousse, more and more astonished, went toward a large oaken cupboard, opened it, and gave the abb a long purse of faded red silk, round which were two copper runners that had once been gilt. the abb
