结构求解与高级单元测试：Python 实现

1. 结构求解代码实现

在进行结构求解时，我们需要完成一系列步骤，包括导入必要的模块、定义结构类以及实现求解方法。以下是具体的代码和步骤说明：

from functools import reduce
from eqs import Matrix, Vector as EqVector, cholesky_solve
from geom2d import Vector
from structures.solution.bar import StrBarSolution
from structures.solution.node import StrNodeSolution
from structures.solution.structure import StructureSolution
from .bar import StrBar
from .node import StrNode

class Structure:
    __DOF_PER_NODE = 2

    def __init__(self, nodes: [StrNode], bars: [StrBar]):
        self.__bars = bars
        self.__nodes = nodes
        self.__dofs_dict = None
        self.__system_matrix: Matrix = None
        self.__system_vector: EqVector = None
        self.__global_displacem
