其中有一點就是中國成了工業列強的原料品供應地，正是在此基礎上，由於中國勞力資源的便宜，國際長途運費的昂貴，以及許多原料品的時鮮性和不便於儲存，它們推動了該類產品的出口加工；也由於出口品高利潤的刺激，和近代中國人對工業化的執著追求以及強烈的愛國精神，促使出口加工業的發展由外商控制到國人投資經營轉化，由加工原料初級品向一定的深加工品轉化，由生產半成品向終端產品轉化，由輕工業品向重化工業品加工轉化，出口替代就這樣發展了起來。它以生絲、絲織、棉紡織、豆類加工、蛋製品、麵粉等加工最為突出，同時也興起一部分重化工業產品如鋼鐵、水泥、酸堿等的加工出口，呈現出一些較明顯的積極的發展趨勢。The process and alkaline bath composition of barrel ni plating for lr6 battery cases was described. the recent trend of ni electroplating for battery cases was also pointed out
