我们描述了最近的工作条纹图案的嵌段共聚物的系统。这种模式表征的副产品是程函方程的新公式。在这个公式中,未知数是形式为P=e e的投影矩阵的场,其中e是单位向量场。我们描述了如何制定更好地适应于描述条纹图案比经典程函方程,并说明这一点与例子。
We describe recent work on striped patterns in a system of block copolymers. A by-product of the characterization of such patterns is a new formulation of the eikonal equation. In this formulation, the unknown is a field of projection matrices of the form P=e⊗e, where e is a unit vector field. We describe how this formulation is better adapted to the description of striped patterns than the classical eikonal equation, and illustrate this with examples.
