+In Kubernetes, CEL can be used to run queries and perform fine-grained
+filtering. For example, you can use CEL expressions with
+[dynamic admission control](/docs/reference/access-authn-authz/extensible-admission-controllers/)
+to filter for specific fields in requests, and with
+[dynamic resource allocation (DRA)](/docs/concepts/scheduling-eviction/dynamic-resource-allocation)
+to select resources based on specific attributes.

+在 Kubernetes 中，CEL 可用于运行查询并进行细粒度的筛选。例如，你可以将 CEL
+表达式用于[动态准入控制](/zh-cn/docs/reference/access-authn-authz/extensible-admission-controllers/)，  
+以筛选请求中的特定字段；也可以与[动态资源分配（DRA）](/zh-cn/docs/concepts/scheduling-eviction/dynamic-resource-allocation)结合使用，
+基于特定属性选择资源。
