HarmonyOS 有个字符串资源文件，后面怎么拼接字符串？

{ 
  "string": [ 
  { 
    "name": 
    "module_desc", "value": 
    "模块描述%d" 
  } 
  , 
  { 
    "name": 
    "EntryAbility_desc", "value": 
    "description" 
  } 
  , 
  { 
    "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%') 
  } 
}
