A quantum-mechanical system is divided into several partial systems which are interacting each other. The general and practical methods of extracting one of the partial systems are discussed. If a one-dimensional partial system is extracted the two-particle interaction in the partial system is a long range part of the two-particle interaction in the original system and its short range part is absorbed in the average field due to the remaining part of the system. It is noted that the light absorption of long carotenoids is due to the plasma oscillation of π electrons caused by the long range part of the Coulomb interaction. The mechanism of screening the short range part is somewhat different from that of the three-dimensional case.
