Firstly, the Green function's source point and field point symmetry and geometry symmetry are discussed, and based on these, symmetry properties used in the matrix solving are discussed. 首先分析了格林函数的场点源点对称性和几何对称性，并由此入手，对对称性在速度势求解矩阵中的应用进行了分析。 - 2
It would have been a perfect symmetry here, because last time we quoted Paul Ricoeur, the main point was that these authors were masters. 这里本来是很平衡的，因为上次我们提到保罗·里克尔的时候，大意是说这些作者都是大师。 - 3
Rotational symmetry (or radial symmetry) is when an object is rotated in a certain direction around a point. 旋转对称(或称放射对称)是指某一物体绕着某一点在某一方向上做转动。
