# 延长订单

扩展功能让你能从已经租赁或即将租赁的能量中获得更多价值。可用于：

* 最大化目标地址可接收的能量数量。
* 延长一块有效能量的时长，且不会有被回收的风险。
* 从同一个代理(委托)地址多次购买更多能量。

TronSave 提供两种方式来实现这一点：

| 方式                                             | 作用                       |
| ---------------------------------------------- | ------------------------ |
| [快速扩展](/chinese/guides/extend/quick-extend.md) | 快速充值，只需几步即可延长一块有效能量。     |
| [高级](/chinese/guides/extend/advance.md)        | 对从同一个代理(委托)地址重复购买进行精细控制。 |

两种方式都建立在标准租赁流程之上。如果你还没有租赁过能量，请从\[如何购买能量和带宽]\(../buy/README.md)开始。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.tronsave.io/chinese/guides/extend.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
