Results： Comparing the disinfection state of hotel through chi - square test, X^2 = 4. 76, P 〈 0. 05 X^2 2004 and 2005 ;X^2 = 71.14, P 〈 0. 01 between the large and medium sized hotels ;X^2 = 4. 34, P 〈 0. 05 between the medium and small sized hotels.X^2 = 103.36, P 〈 0. 01 between the large and small sized hotels. Comparing the different tableware disinfection state between 2004 and 2005, we found the following results：cup： X^2 = 10. 21, P 〈0. 01 ; basin： X^2 =4. 17, P 〈0. 05; plate： X^2 = 4. 78, P 〈 0. 05; bowl ： X^2 = 15. 94, P 〈 0. 01 ; chopstickt： X^2 = 7. 99, P 〈 0. 01 ; dish： X^2 = 3. 55, P 〉 0. 05; box： X^2 = 3.55, P〉 0. 05. Condusion： The qualification rate （the eligible rate） of hotels of Taiyuan city in 2004 and 2005 is 70. 55% and 74. 47%, respectively.
