+### 状态变量多种数据类型声明使用限制。
+
+状态变量比如@State、@Provide、 @Link和@Consume等，定义数据类型时，只能同时由简单数据类型或对象引用数据类型其中一种构成。
+
+示例：
+
+```ts
+@Entry
+@Component
+struct Index {
+  //错误写法: @State message: string | Resource = 'Hello World'
+  @State message: string = 'Hello World'
+
+  build() {
+    Row() {
+      Column() {
+        Text(`${ this.message }`)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+
+**变更影响**
+
+当定义的状态变量类型中同时包含简单类型和对象引用数据类型时，编译报错提示不支持。

+**关键的接口/组件变更**
+
+当定义的状态变量类型中同时包含简单类型和对象引用数据类型时，需修改为只含有其中一种，如上述示例代码所示。
