1.精密称取适量的组分A和组分B,质量比1：1
2.加入适量酒精（酒精/组分A=10：1）,使组分A为100mg/ml,在室温下保存
3.在使用前,在上述溶液中加入酒精,调节组分A的浓度为10mg/ml

Answer 1

take appropriate amount of A and B and weight them accurately with  a ratio of 1:1
add alcohol accordingly (alcolhol/A=10:1),so A's concentration is 100mg/ml,store under room temperature
before use,dilute the previous solution with alcohol so that A's concentration is 10mg/ml
