過浸蝕 的英文怎麼說
中文拼音 [guòjìnshí]
過浸蝕
英文
over etching-
They immersed a lead object first in copper acetate ( a compound made by letting vinegar corrode copper ), and then in a silver solution created by dissolving silver chloride in dilute ammonia ( which ancient chemists made from urine )
它們首先把鉛製品浸沒在醋酸銅（通過醋酸腐蝕銅而制得的化合物）中，然後放在銀溶液中，銀溶液是通過把氯化銀溶解在稀釋的氨水（古代化學家從尿中制得）中而制得的。The control system of mould level is crucial to improve the slab quality in the continuous casting process, pid controller is used in the traditional mould level control, and it has some defaults, such as : at the start - up or finishing period of casting or during the changeover of tundish, pid control has a bad effect, its overshoot is large and its transient time is long ; the erosion of the tundish stopper and the submersed nozzles lead to the accuracy of control become bad ; the abrupt falloff of block in the submersed nozzles makes the level acutely fluctuate, and pid control can not overcome the disturbances resulted from the change of casting speed
結晶器液位控制系統是提高連鑄產品質量的關鍵環節，傳統的連鑄機液位控制方法採用常規的pid控制，存在如下不足：開始、結束澆注和換中間罐澆注時，控制效果差，超調量大，過渡時間長；塞棒頭和浸入式水口被腐蝕后引起控制精度差；浸入式水口堵塞物的突然脫落所引起的液位劇烈波動；無法克服拉速波動引起的擾動。Overgrazing ( again, widely practised by " traditional " cultures ) causes soil erosion and turns fertile pasture into desert
過度放牧（這同樣也被「傳統的」耕作所廣泛採用）導致了土壤浸蝕，並把肥沃的草原變成了沙漠。The resultant effect is spectacular : the waters spill on a series of steps, forming solid cascades and pools
泉水的下瀉?產生浸蝕及沉澱作用?經過無數的歲月?形成了大小白棉班狀的巖石?層層疊疊。Oxidation erosion, liquid aluminum erosion and the erosion mechanism of grey cast iron crucible for aluminum melting were described in detail. the methods such as alloying of as - cast surface for improving oxidation resistance of the grey cast iron crucible and both composition adjustment and infiltration protection for improving liquid aluminum erosion resistance of the crucible were introduced. the corrosion resistance and service life of grey cast iron crucible were improved effectively with these methods through decreasing various channels of erosion developing from the surface to the inner of crucible
詳細論述了熔鋁灰鐵坩堝的氧化腐蝕、鋁液腐蝕及其腐蝕機制，介紹了能夠提高灰鐵坩堝抗高溫氧化能力的鑄態表面合金化法和能夠提高灰鐵坩堝抗鋁液腐蝕能力的調整成分法與浸滲保護法，這些方法通過減少腐蝕由坩堝表面向基體內部發展的各種「通道」 ，有效地改善了灰鐵坩堝抗腐蝕性能，提高了坩堝使用壽命。Abstract : oxidation erosion, liquid aluminum erosion and the erosion mechanism of grey cast iron crucible for aluminum melting were described in detail. the methods such as alloying of as - cast surface for improving oxidation resistance of the grey cast iron crucible and both composition adjustment and infiltration protection for improving liquid aluminum erosion resistance of the crucible were introduced. the corrosion resistance and service life of grey cast iron crucible were improved effectively with these methods through decreasing various channels of erosion developing from the surface to the inner of crucible
