脫金屬率 的英文怎麼說
中文拼音 [tuōjīnzhǔlǜ]
脫金屬率
英文
demetallization percent-
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。But some problems are occurred, such as low bath temperature, difficulty in lime melting, slag overflow at vessel mouth, increase of metal consumption, difficulty in dephosphorization and low hitting rate at the final
在生產中出現熔池溫度低、廢鋼和石灰不易熔化、爐口溢渣、金屬消耗增加、脫磷困難、終點命中率低等問題。By considering the effect of different binders, basicity, reduction temperature and time on the compression strength and dezinc degree after reducing, find out the best scheme a1b3c3d3 and get the metallic pellets with higher compression strength and dezinc degree
通過研究不同粘結劑、堿度、還原溫度和還原時間對熟球抗壓強度、脫鋅率的影響，找出最佳試驗方案為a1b3c3d3 ，得到脫鋅率和抗壓強度較高的金屬化球團。The bimetal cementation, the compound material and the metal cementation, the compound material and the compound material cementation three types of lamination boards delaminates on its natural frequency had been separately studied and delaminating with the natural frequency relations diagram of curves had been drawn up
文中分別研究了雙金屬粘接、復合材料與金屬粘接、復合材料與復合材料粘接三種類型的層合板脫層對其固有頻率的影響，並繪制了脫層與固有頻率關系曲線圖，為工程應用提供了科學依據。However, due to the low adhesive strength between diamond particles and metal matrix, diamond grits are prematurely pulled out during cutting, which leads to an increase of tool cost and a decrease of machining efficiency
然而，由於大多數金屬胎體不能實現對金剛石磨粒的有效粘結，造成鋸片使用過程中金剛石磨粒的過早脫落，導致金剛石鋸片成本增加、加工效率降低。分享友人
