但它不仅可以序列化栈，还可以序列化堆中的对象。

But it does have the ability to serialize not only the stack but also objects on the heap.

栈中最底部的是任务的起始活动——一般是用户在滑出的程序列表中选择启动的活动。

The root activity in the stack is the one that began the task — typically, it's an activity the user selected in the application launcher.

并在此基础上提出了基于栈结构的支持度计算算法，该算法仅对数据库进行一次扫描，即可实现候选序列的计数操作。

Then it presents a support computing algorithm based on stack structure, which can count the candidate sequences by scanning the database only once.
