emdical是什么意思呀?怎么也查不到.

肯定是个错别字，正确拼写为：
medical
1.医学的；医术的
2.内科的

如：He is a medical student.
他是个医科学生。
The doctor gave him a medical examination.
医生给他作了体格检查。
He's a member of the medical fraternity.
他是医务界的一员。
Before you join the company, you will have to have a medical examination.
进本公司前,你得先做体格检查。

你写错了,应该是emend [iˈmend]
