crystallizing nucleus 中文意思是什麼
crystallizing nucleus
解釋
結晶核- crystallizing : 結晶的
- nucleus : n （pl nucleuses nuclei ） 核；核心；【生物學】細胞核；核；【物理學】原子核；【化學】有機化合物的...
-
When ph value < 0. 5, faster deposition rate, faster growth rate of crystallizing nucleus, which causes bigger crystalline granularity and bad surface quality of the deposits such as crassitude or darkling
Ph 0 . 5時，沉積速度過快，晶核成長速度快，晶粒粒度較大，鍍層表面粗糙、發黑，表面質量差。 -
When sn2 + concentration in the bath is lower, sn2 + activity is not enough causes slow deposition rate and slow growth rate of crystallizing nucleus, so crystalline granularity deposited is smaller ; when sn2 + concentration in the bath is higher, the dispersive ability of the bath decreases and the surface quality of the deposits sets worse
鍍液中sn ~ （ 2 + ）濃度較低時，離子活度不夠，沉積速度慢，晶核成長速度慢，使沉積的晶粒粒度較小； sn ~ （ 2 + ）濃度過高，鍍液分散能力降低，使鍍層的表面質量下降。 -
Higher bath temperature and more deposition time, faster deposition rate, faster growth rate of crystallizing nucleus, which causes bigger crystalline granularity ; ph value and bath temperature are also key factors affecting the size of crystalline granulatrity
鍍液溫度越高、時間越長，沉積速度越快，晶核成長的速度就越快，沉積晶粒的粒度也越大。鍍液ph值和sn ~ （ 2 + ）離子濃度也是影響晶粒粒度大小的關鍵因素。
