The question of growth is nothing new but new disguise for an age-old issue, one which has always intrigued and preoccupied economics: the present versus the future. -James Tobin If you have ever spoken with your grandparents about what their lives were like when they were young, most likely you learned an important lesson over about economics: material standards of have improved substantially over form time for most families in most countries

1范围 本方法的检出浓度为0.03mg/L,测定上限为5.0mg/L(相当于10.0mg/LHBO2)可用于饮 用水、地面水中硼的测定。 锡、碲、汞与显色试剂生成白色沉淀,铝、铍、钛、锆钒、镓、钼(VI)生成黄色;铜、 铬生成棕黄色;铁(III)铁(I)均对测定有干扰,可用EDTA加以掩蔽;钾、钠的存在会减缓 反应的速度,但可延长反应时间,在6h后再进行测定而消除干扰
