我们生活在一个充满对称的世界中,从自然景观到分子结构,从建筑物到艺术作品,甚至日常生活用品,人们都可以找到对称的例子,本文试举几例,谈谈轴对称在生活中的应用．一、巧妙设计最短输水管线例1 如图1,要在河道l上修建一座水泵站,分别向A、B两镇供水,问:水泵站建在河道的什么地方,可使所用的输水管线最短? 分析:我们可以把河道近似地看成一条直线l,问题就是要在直线l We live in a world full of symmetries, from natural landscapes to molecular structures, from buildings to works of art, even everyday objects, people can find symmetrical examples. Here are a few examples to talk about axisymmetric in life. Applications. First, cleverly designed the shortest water pipeline Example 1 As shown in Figure 1, a water pump station should be built on the river l to supply water to the towns of A and B respectively. Q: Where the pump station is built in the river, it can be used to transport water. The shortest pipeline? Analysis: We can approximate the river as a straight line l, the problem is to be in the line l
