在英语中，如果我们想要表达，关于某件事情的更多细节，或者， 更详细的讨论某个问题，可以用
detailed:
For more detailed discussion，a more detailed explanation of the word "detail" is given.
detail:
in more detail,
detais 是 detail 的复数plural, 比如说，多个细节，我们可以说 many details, several details.
detail 也可以做不可数名词，意为 细节。 比如， 这幅画缺少细节：
His drawing lacks detail and looks rushed because he did not add enough detail around the eyes and the details there really matter. details that make someone recognizable. I wonder if he could add more detail if I looked up his details (meaning specific info about him)and emailed him my opinion, in detail.
这里，“in detail” 和 “detailed” 意义相同
Example: "The features of the car are listed "in detail" on the next page." and is the very similar to "A detailed list of features for this car is located on the next page."
You could also say: "Go to the next page to see the details of each feature on this car." All mean that the features of the car will be described independently and explained completely.
