Keeping Ahead in Healthy Flooring Standards:"Zero distance to health" is not just a product slogan. In 2004, Power Dekor was devoted to the E0 level HDF/MDF production line. From the increase of raw materials' purity to veneering and laminating, the American technique BORDEN has been adopted throughout the whole process. It means another upgrade of technology in wood flooring industry, and the health standard of the industry has been pushed forward again. In 2006, Power Dekor has brought out Anion Flooring Series and the healthy function of laminate flooring would benefit consumers once more.

引领健康地板生产标准："健康O距离"不只是一句产品宣传口号。2004年，圣象集团倾力打造的E0级基材生产线，从提高原材料纯度到制胶和压制，全过程采用了美国BORDEN工艺技术，标志着木地板生产技术的再次升级，同时将行业内的地板健康标准向前推进了一大步。2006年，圣象负离子抗菌地板面市，强化木地板产品健康功能又一次让消费者受益。

From the graph, we can know that the graph of y=kx+b, is crossing the point of (0,b), and is parallel with the line of y=kx. And in the point of (0,b), o is x and b is y . In this situation, zero can be the divisor. It can be the scientific gist.

从正比例函数和一次函数的图象可知，一次函数y=kx+b在坐标平面上的函数图象是经过(0，b)且平行于正比例函数y=kx的一条直线，这其中的点(0，b)，0表示x，b表示y，在这样的情况下就成了零作除数的情景，这可说是零能作除数的科学依据。
