美国俄亥俄州立大学的科学家最近发明了一种可以降低钙镁醋酸盐（ＣＭＡ）生产成本的方法。这种方法可以使ＣＭＡ的生产成本从原来的每吨１０００美元 ,降至每吨２００～３００美元。据报道 ,美国和加拿大两国每年冬季为了融雪 ,都得在公路上洒１０００万～１５００万ｔ盐。但
Scientists at Ohio State University recently invented a method that can lower the cost of calcium-magnesium-acetate (CMA) production. This method can make CMA production costs from the original 1000 US dollars per ton, down to 200 to 300 US dollars per ton. It is reported that the United States and Canada each have to sprinkle 10 million to 15 million tons of salt on the roads every year in order to melt snow. but
