摘要：
We show that the environment affects a quantum system in the form of the constrained trajectory. Our result allows one to describe the quantum system in terms of stochastic state vector rather than quantum history. Moreover we can alternatively reduce the time evolution operator. Then the trajectory of system is constrained.
