查询词典 operator function

The operator new function next checks whether there are any objects on the freelist. If not, it asks the allocator member to allocate chunk new, unconstructed objects. It then iterates through the newly allocated objects, setting the next pointer.

operator new 函数接着检查自由列表中是否有对象，如果没有，它就请求 allocator 成员分配 chunk 个新的未构造对象，然后，它通过新分配的对象进行迭代，设置 next 指针。

The main contents are as follows.1 For the state control problem in closed quantum systems, according to the distance between states, the error between states and the average value of an imaginary mechanical quantity, three Lyapunov functions are chosen, respectively. The corresponding control law designs and the convergence analyses are studied. Especially, for the Lyapunov function based on the distance between states, a class of control laws that can solve the problem that an initial state is orthogonal to a goal state is designed. The convergence of the system is analyzed via LaSalle\'s principle and one method to find the largest invariant set of the closed loop system is proposed by linearizing the unitary evolution operator at the corresponding instants.
