Base1* b1 =newDerived; b1->f1; 其正常工作,不需要移动任何指针,这是因为b1指向Derived对象的首地址。 那么如下是下面这种情况呢? Base2* b2 =newDerived; // 相当于 Derived *d = new Derived; // Base2* b2 = d + sizeof(Base1); b2->f2; 对于创建对象操作,在上述代码中有大致解释,那么对于b2...

A supercell in 2D can be created using linear combinations of the primitive unit cell vectors (a1, a2). The corresponding supercell lattice vectors (b1, b2) are written as: $${{{\bf{b}}}_{1}={n}_{1}{{{\bf{a}}}_{1}+{n}_{2}{{{\bf{a}}}_{2},$$ (1) $${{{\bf{...
