An evaluation method for residual hydrocarbon of post- to over-mature marine source rocks includes the following steps: establishing a hydrocarbon generation potential evolution profile and a hydrogen index evolution profile of post- to over-mature source rocks; determining a critical condition for hydrocarbon expulsion of the source rocks, and inverting original hydrocarbon generation potential of the source rocks; inverting a critical condition for hydrocarbon generation of the source rocks; establishing a hydrocarbon generation, expulsion and retention model for the source rocks; determining a hydrocarbon generation rate, a hydrocarbon expulsion rate and a hydrocarbon retention rate of the source rocks; and calculating a hydrocarbon retention intensity and residual hydrocarbon of the source rocks. The evaluation method establishes an evaluation model for residual hydrocarbon of post- to over-mature source rocks without relying on immature to sub-mature samples.

The present invention relates to a meal service management system and an operating method therefor, the system being capable of providing information on food ingested by a user to whom a meal service is to be provided and customized information related thereto, and managing food leftover in a meal service. According to an embodiment of the present invention, a scanner device is used such that a user to whom a meal service is to be provided and a food tray before and after meals are identified, and thus a meal service amount and a leftovers food amount are acquired, and leftovers food information of each user and useful information associated therewith are provided on the basis of the same, and thus users can easily determine their eating habits, nutritional status and the like and the users can be induced to attempt reducing leftovers food by themselves.

The present invention discloses a charging socket. The charging socket has a housing; a charging terminal installed in the housing; an electric adapter installed in the housing; and a temperature sensor for detecting the temperature of the charging terminal. The electric adapter has a body and a connection terminal provided in the body, and the connection terminal has an input end and an output end. The temperature sensor has a flexible lead, which is electrically connected to the input end of the connection terminal, so as to transmit the sensing signal of the temperature sensor to the output end of the connection terminal.
