Abstract: A test card and a test display adapter are disclosed. The test card includes an assembling plate and an electrical heat source. The electrical heat source is provided on the assembling plate. The electrical heat source includes a first heat transfer plate, a second heat transfer plate and at least one heat source element. The first heat transfer plate is stacked on the assembling plate, and the second heat transfer plate is laminated over the first heat transfer plate, with the heat source element being sandwiched between the first and second heat transfer plates. The test card and the test display adapter have a wide variety of advantages including very low cost, easy material availability, a short wait time, easy manufacturability, a long service life, easy modifiability and good interoperability.

Abstract: Provided are a font adjustment method, a font adjustment apparatus, a storage medium, and an electronic device. The font adjustment method includes: obtaining an application currently running on an electronic device (102); determining a display type of the application based on a predetermined correspondence relation between part or all of applications in the electronic device and corresponding display types (102); determining font weight setting information of the display type (103); and adjusting, based on the font weight setting information, a font in a display interface of the application (104).

Abstract: A liquid-cooling heat sink is disclosed which includes a substrate, a cover and a separator. The substrate includes a plate, a set of first heat sinking fins and a set of second heat sinking fins. The cover has water inlet and outlet ports. The cover and the plate together delimit a heat exchange chamber in which both the set of first heat sinking fins and the set of second heat sinking fins are confined. The separator is disposed between the set of first heat sinking fins and the set of second heat sinking fins to divide the heat exchange chamber into a water inlet compartment and a water outlet compartment. The water inlet compartment and water outlet compartment are in communication with the water inlet and outlet ports respectively. The liquid-cooling heat sink has not only enhanced overall structural strength but also improved heat exchange efficiency with a coolant fluid.
