Electric heating or direct flame heating can be applied. However, during workshop manufacturing, electric heating should be applied as possible under the Pre-requisite of temperature balance.

采用电加热或火焰直接加热，但在车间制造过程中，为了确保温度均衡的前提下，尽量采用电加热。

Or I could have a non-adiabatic, I could take the same temperature change, by taking a flame, or a heat source and heating up my substance. So, clearly q is going to depend on the path.

也能改变温度，绝热指的是没有热传递，在非绝热条件下，也同样可以升温,比如用火或者热源加热，这样，q也应当与路径有关。
