摘要
The experiment of measuring the spin depolarized time and light storage time in a Rb vapor under different conditions is performed. Typically, these measurements are accomplished in three different containers： atoms in a bare glass cell, atoms in a buffer gas cell, and atoms in a tetracontane （C4oH82） coating cell. The increasing depolarization and storage times are observed in both the buffer gas cell and the tetracontane coating cell. In the latter case, a storage time greater than 400μs is obtained.
