水,我们都很熟悉,我们的生活离不开水。古人说:“山无常形,水无常态。”水本身是富于变化的,更重要的是,从不同的角度我们可以写出不同的水。水(化学式:H2O)是由氢、氧两种元素组成的无机物,无毒。在常温常压下为无色无味的透明液体,被称为人类生命的源泉。水,包括天然水(河流、湖泊、大气水、海水、地下水等){含杂质},蒸馏水是纯净水,人工制水(通过化学反应使氢氧原子结合得到的水)。 Water, we are all familiar with our lives can not do without water. The ancients said: “The mountain is impermanence and the water is impermanence.” Water itself is highly variable, and more importantly, we can write different water from different perspectives. Water (chemical formula: H2O) is composed of hydrogen, oxygen two kinds of inorganic elements, non-toxic. Colorless and tasteless at room temperature and pressure of transparent liquid, known as the source of human life. Water, including natural water (rivers, lakes, atmospheric water, sea water, groundwater, etc.) {impurities}, distilled water is pure water, artificial water (through the chemical reaction of hydrogen atoms and water).
