为了解决一个问题,或者解一道数学题,有时可以通过对问题中的一部分量进行有限次调整,让其它对象暂时不变,得出局部结果之后,再做进一步调整和研究(有时是重复性的调整),从而缩小范围,最终得到整个问题的圆满解决,这种思维方法就叫局部调整法.著名的几何学家斯坦纳在《等周问题与轴对称》一文中也就是用了这种“局部调整法”证 In order to solve a problem or solve a math problem, it is sometimes possible to make further adjustments and studies (sometimes repetitive) by making a limited adjustment to a part of the problem so that other objects do not change temporarily. (adjustment), so as to narrow the scope, and finally get a complete solution to the whole problem. This thinking method is called local adjustment method. The famous geometrician Steiner used this kind of “isometric problem and axial symmetry” article. Partial adjustment method
