-减少引用计数。
+原子地减少引用计数。
 
 **描述**
 
 原子地减少引用计数。当引用计数归零时，对象会自动 `delete this`。这是实现自动内存管理的关键方法。
 
-**复杂度：** O(1)（归零时为 O(n)，n 为对象大小）
+**线程安全：** ✅
+
+**复杂度：** O(1)
 
 **示例：**
 
 ```cpp
 #include <XCEngine/Core/RefCounted.h>
+#include <cstdio>
 
-class MyObject : public RefCounted {
+class MyObject : public XCEngine::Core::RefCounted {
 public:
-    void DoSomething() { /* ... */ }
+    void DoSomething() { }
 };
 
-// 创建对象（构造时 refCount = 1）
-MyObject* obj = new MyObject();
-
-// 手动增加引用
-obj->AddRef();  // refCount = 2
-
-// 释放引用
-obj->Release();  // refCount = 1
-obj->Release();  // refCount = 0, 对象被自动 delete
+int main() {
+    MyObject* obj = new MyObject();
+    printf("After create: %u\n", obj->GetRefCount());
+    
+    obj->AddRef();
+    printf("After AddRef: %u\n", obj->GetRefCount());
+    
+    obj->Release();
+    printf("After Release: %u\n", obj->GetRefCount());
+    
+    obj->Release();
+    return 0;
+}
