be not necessarily so

基本解释

Foie-gras production can be a form of abuse but is not necessarily so, for an enlarged liver can still be healthy.

So, we just want to appreciate that what we'll be using in this class is, in fact, the solutions to the Schrodinger equation, and just so you can be fully thankful for not having to necessarily solve these as we jump into the solutions and just knowing that they're out there and you'll get to solve it at some point, hopefully, in your careers.
所以，我們僅僅想要鋻別,將會在這門課中用到的，事實上就是薛定諤方程的解，而且你們可以非常訢慰,因爲你們沒有必要去,解這些方程而是直接用它們的解,竝且知道這些解出自那裡,希望你們在學習生涯中。
