The method includes: reading, between two times of the data synchronization, flag information of a first data record item which is required to be added to the changelog; searching for whether there is a second data record item including the flag information in the changelog, and in a situation that there is the second data record item, setting the second data record item according to the first data record item. By the present invention, the changelog file can be prevented from continuously increasing.

Real-time translation system that automatically distinguishes multiple languages and the method thereof

A real-time translation system that automatically distinguishes multiple languages and the method thereof are provided. This solves the problem of being unable to translate a document containing multiple languages. Each sentence in the document is decomposed into multiple words and the language of each of which is determined. The languages of the words in the context are then used to adjust the translation. The mechanism can achieve the effect of precision translation.

Base station

Embodiments provide a base station, including an antenna unit and a radio frequency unit. A port corresponding to a receive channel that is of the radio frequency unit and in a working state and a port corresponding to a transmit channel that is of the radio frequency unit and in the working state are separately connected to ports corresponding to different dual-polarized dipoles or different single-polarized dipoles in the antenna unit. The different dual-polarized dipoles or the different single-polarized dipoles in the antenna unit are mutually isolated.
