An electric junction box, which can be easily assembled even if the electric junction box includes an electric power distributing unit, is provided.
本发明提供一种易于装配的电连接盒，即使所述的电连接盒包括电力分配单元。
At the junction where the two layers meet, electrons pair up with holes, establishing an electric field that prevents electrons from moving from the n-type material to the p-type.
两层接触处电子与“孔”便成双配对地形成了电场，阻止电子从n层移到的p层。
Forcing an electric current across that junction causes the metal on one side to heat up, and the metal on the other side to cool down.
电流通过中间的调节器，使其一端的金属升温，并使另一端的金属降温。
