    • A method of determining a starting point (12) of a segment (11) corresponding to a semantic unit of an audiovisual signal includes processing an audio component of the signal to detect sections (14) satisfying a criterion for low audio power, and processing the audiovisual signal to identify boundaries of sections corresponding to shots. A video component of the audiovisual signal is processed to evaluate a criterion for identifying video sections formed by at least one shot of a certain type, comprising images in which an anchorperson is likely to be represented. If at least an end point of a section (14) satisfying the criterion for low audio power lies on a certain interval between boundaries of an identified video section (13), a point coinciding with a section (14) satisfying the criterion for low audio power and located between the boundaries of the identified video section is selected as a starting point (12) of a segment (11). Upon determining that no sections satisfying the criterion for low audio power coincide with an identified video section (13), a boundary of the video section is selected as a starting point (12) of a segment (11).

    • Provided are a vacuum thermal performance test device for a two-phase fluid loop, and a test method, for testing and evaluating the heat transfer capability and the blocking performance of a two-phase fluid loop at different operating temperatures. The test device comprises a heat dissipation plate (11), a temperature control heater, a multi-layer heat insulation assembly, a temperature sensor, a simulation heat source (15) and a loop support (17). The operating temperature of a two-phase fluid loop is altered by controlling the temperature of an evaporator (1) and the temperature of the heat dissipation plate (11). The test method tests the heat transfer and blocking capabilities of the vacuum thermal performance of a gravity-driven two-phase fluid loop. The arrangement of the temperature sensor is beneficial for the observation of the state of an ammonia working medium within the two-phase fluid loop, each component within the two-phase fluid loop is examined as to whether a temperature requirement is satisfied, and the two-phase fluid loop is also examined as to whether balance is achieved.

    • Provided are a device and a method for testing the compatibility of a gravity-driven two-phase fluid loop. The test device and method can effectively simulate the decomposition process of an ammonia working substance in the gravity-driven two-phase fluid loop in the case of a high temperature with nickel as a catalyst to judge the compatibility of the gravity-driven two-phase fluid loop. Firstly, a test device for simulating the decomposition process of the ammonia working substance in the gravity-driven two-phase fluid loop during a moon day is designed, then the amount of non-condensable gases produced during a moon day from the ammonia working substance in the test device is measured using a method for testing a non-condensable gas in a gravity assisted heat pipe, and then a high-purity nitrogen in the same substance amount as that of the non-condensable gases is filled into the gravity-driven two-phase fluid loop to achieve the determination of the compatibility of the gravity-driven two-phase fluid loop. The test device is simple, and the test method is rapid, convenient and effective.
