After removal of the electric field, ceramics retained some polarization, so that the ceramics have piezoelectric properties, may be called the piezoelectric ceramic. 11)超导体:在超低温下失去电阻的性质称为超导电性,相应的这类物质称为超导体。superconductors: the nature of materials losing resistance ...
The area of an atom where electrons are most likely to be located is known as an electron shell, also known as an energy level or an electron orbital. Each shell has a distinct energy level and can only hold a certain amount of electrons. For instance...
