审视 (shěn shì) means 'to scrutinize' — to examine something very carefully and in detail, often with a critical or evaluative eye. It's stronger and more thorough than 查看 (chá kàn, 'to check/look over'), which is a general inspection. 审视 can apply to documents, situations, or abstract things (like one's own mistakes), whereas 审 (shěn) is more formal, often used in legal or investigative contexts.
