您做一个普通纯净水和专业纯净水的对比给大家看看不是更好吗？ 请拿数据说话： Lord Kelvin, 1883 “I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it …”“But when you can not measure it, when you can not express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.”
