According to the invention, food storage information in the refrigerator can be detected through the pressure sensor module so that a user can grasp food storage timely; and then a food deterioration probability proportion value is obtained through integrated analysis of the integrated analysis determining module so that the user can grasp a food deterioration condition timely.

The invention provides a method for pressure analysis during an application software performance test. The method comprises the following steps: production data of a typical on-line service application system is analyzed based on pressure model analysis of TPS during the software performance test so as to obtain the TPS of a key service, when the number of system users increases, the access pressure of the system also increases, the pressure of the system is proportional to a TPS value, the analyzed TPS is multiplied by a pressure multiplication factor which possibly increases to obtain a pressure design index to be simulated in the performance test so that the pressure of the system is really simulated, and the performance of the system at the pressure is tested. When the number of the system users increases, the access pressure of the system also increases, the pressure of the system is proportional to the TPS value, the TPS value can be estimated after the number of the users increases, and the TPS value is taken as a target for generating pressure during the performance test, which can really simulate the pressure on the system from a great number of user operations, accurately test the handling capacity of the system, and help make a decision to expand the application system or not.
