Entropy property of V-type atom interacting with a cavity-field through Raman process system in an amplitude damping cavity;

And the results show that the damage degree of velocity sensitivity is weak in this reservoir,and its damage degree of water sen- sitivity is weak,and at the same time this reservoir is damaged owing to the low acid sensitivity and the middling weak a(?)kali sensitivity.
