ArkUI组件的字符串中如何实现字符串变量拼接

{ 
  "string": [ 
    { 
      "name": "module_desc", 
      "value": "模块描述%d" 
    }, 
    { 
      "name": "EntryAbility_desc", 
      "value": "description" 
    }, 
    { 
      "name": "EntryAbility_label", 
      "value": "label" 
    } 
  ] 
}

{ 
  "string": [ 
    { 
      "name": "module_desc", 
      "value": "module description%d" 
    }, 
    { 
      "name": "EntryAbility_desc", 
      "value": "description%d" 
    }, 
    { 
      "name": "EntryAbility_label", 
      "value": "label" 
    } 
  ] 
}

@Entry 
@Component 
struct Page1 { 
  @State num1: number = 100; 
 
  build() { 
    Row() { 
      Column() { 
        Text($r('app.string.module_desc', this.num1)) 
          .fontSize(50) 
          .fontWeight(FontWeight.Bold) 
      } 
      .width('100%') 
    } 
    .height('100%') 
  } 
}
