  • Publication number: 20180060290
    Abstract: An aided translation method and a device thereof, belonging to the field of Human-Computer Interaction. The method comprises the steps of: obtaining a destination from the itinerary information of a user; translating the pre-stored personal form-filling information of the user from a source language to a target language when the language of the destination is different from that of the user's usual place of residence, wherein, the target language is the language of the destination; and displaying the personal form-filling information in the target language. The method and a device solve the problem of users in filling in the arrival/departure card caused by unfamiliarity with foreign languages and the form-filling formats, and achieve an effect that users can fill in the arrival/departure card easily by reference to the personal form-filling information displayed in the target language.

    Abstract: A composite membrane for selectively pervaporating a first liquid from a mixture comprising the first liquid and a second liquid. The composite membrane includes a porous substrate comprising opposite first and second major surfaces, and a plurality of pores. A pore-filling polymer is disposed in at least some of the pores so as to form a layer having a thickness within the porous substrate. The polymer is more permeable to the first liquid than the second liquid but not soluble in the first liquid or the second liquid. The composite membrane may be asymmetric or symmetric with respect to the amount of pore-filling polymer throughout the thickness of the porous substrate.
