immersion time的用法和樣例：
例句
- Longer steeping time is required for the consequent rounds.
後續的步驟需要更長的浸漬時間。 - But if the quality can be guaranteed pollution-free, and seaweed, you do not bother, because the soaking time is too long, kelp nutrients will be dissolved in water.
但如果是質量能夠保證的無公害海帶，就不必費心了，因為浸泡時間過長，海帶中的營養物質也會溶解於水。
