这两个单词很容易弄混。
Don’t mix up dissatisfied with unsatisfied. Dissatisfied applies only to people who are unhappy, frustrated or disappointed with a thing, person or situation.
简单说来，dissatisfied是指对某事情不满意；而unsatisfied是指对某事情不满足，其不满程度更进一层，且多在精神层面。
Examples:
" I was dissatisfied with the service I received at the restaurant.
" She was dissatisfied with his response to her question.
Unsatisfied refers to the feeling of needing more and can be used with abstract items. Examples:
" Despite the hearty meal, his hunger remained unsatisfied.
" She has had the bill for three weeks, but it still remained unsatisfied.
