```
feat(slice): 添加切片详细示例和图片资源 - 在README.md中添加image-2.png、image-3.png、image-4.png图片引用， 用于说明切片操作的可视化内容 - 将"通过切片创建新的切片"章节内容重新排序至切片拷贝部分之后 - 在main.go中增加多种切片声明方式的代码示例 - 补充切片访问、遍历、引用类型特性、深拷贝等完整示例 - 添加append.drawio和ref.drawio绘图文件，提供切片操作流程图 ```

## 通过切片创建新的切片
|
|
||||||
|
|
||||||
**原理**：切片操作创建新的切片视图，共享底层数组。新切片的长度是high-low，容量是原容量减去low。
|
|
||||||
|
|
||||||
```go
|
|
||||||
s := []int{0, 1, 2, 3, 4, 5}
|
|
||||||
|
|
||||||
// 创建子切片：s[low:high] (不包括high)
|
|
||||||
sub1 := s[1:4] // [1, 2, 3]
|
|

fmt.Println(sub1)

## 切片拷贝
