是因为再点击重置的时候你的input或者checkedbox没有绑定value值或者v-bind

<a-input placeholder="请输入检查项目" @change="changeProject" :value='project'></a-input>
<a-checkbox @change="onChangeBenchmarking" v-model="benchmarking">
  仅显示对标标准
</a-checkbox>

data () {
	return {
		benchmarking: false,
	}
}
searchReset () {
  this.project = '';
  this.serial = '';
  this.content = '';
  this.benchmarking = false;
  // 清空以后重新刷新页面
  this.quearyEvear();
}
