求翻译：用沸水浸于400毫升烧杯中，加盐酸10毫升，加热使可溶性盐类溶解，取下，用(1+1)氨水溶液中和至PH=7~8，加热煮沸1~2分钟取下，待沉淀下沉后，以快速滤纸过滤，用1%氯化钠热溶液洗涤沉淀及烧杯各3次，再继续洗沉淀3~4次.是什么意思？

Immersed in 400 ml beaker with boiling water, add 10 ml hydrochloric acid, heated to dissolve the soluble salts, removed, with the (1 +1), ammonia solution and to PH = 7 ~ 8, heat to boil 1 to 2 minutes to remove, be precipitated after sinking to fast filter paper with hot 1% sodium chloride solutio
