英语 良性循环怎么说

In English, a benign cycle is a situation in which a positive event or condition leads to another positive event or condition, which in turn leads back to the first event or condition. This can create a cycle of positive events or conditions that continue to reinforce each other.
For example, if a person receives a promotion at work, this may lead to an increase in income, which may in turn lead to an improvement in their financial situation. This improved financial situation may allow the person to make positive changes in their life, such as taking more vacations or making more charitable donations, which may lead to increased happiness and satisfaction. This cycle of positive events or conditions can continue, creating a benign cycle.
Some other ways to describe a benign cycle in English might include:
A positive feedback loop
A virtuous circle
A self-reinforcing cycle
A reinforcing feedback loop
A self-sustaining cycle
