A method for detecting a multicast service flow includes receiving, by a first node, a multicast service flow from a multicast source; encapsulating, by the first node, an In-situ Flow Information Telemetry (IFIT) extension header into a data packet in the multicast service flow, where the IFIT extension header includes a first detection identifier, and the first detection identifier is used to identify the detected multicast service flow; copying, by the first node according to a quantity of next-hop second nodes of the first node, the data packet encapsulated with the IFIT extension header; and sending, by the first node to each next-hop second node, the data packet encapsulated with the IFIT extension header. The first node is a head node in a multicast detection domain.

Provided are a SiC/ZrC composite fiber, a preparation method and use thereof. The SiC/ZrC composite fiber has a diameter of 10 to 70 μm. The method includes mixing liquid polycarbosilane with a zirconium-containing polymer to obtain a hybrid spinning solution, and then performing electrospinning to obtain a SiC/ZrC composite fiber precursor, crosslinking and thermally treating the SiC/ZrC composite fiber precursor in a protective atmosphere to obtain the SiC/ZrC composite fiber. The SiC/ZrC composite fiber is continuous and uniform, has an adjustable diameter, and thus has outstanding tensile strength and breaking strength and excellent high-temperature resistance. Without use of any organic solvent or spinning agent, the method achieves short process flow and high yield, indicating wide application prospects.

The present disclosure relates to a video connection method and apparatus. The method includes: obtaining matched video connection requests from a plurality of video connection requests; creating a video connection room for the matched video connection requests; generating identification information of the video connection room; and informing a first client and a second client of entering the video connection room and making a video connection by sending the identification information of the video connection room to the first client and the second client corresponding to the matched video connection requests respectively.

Video connection method and apparatus, and non-transitory computer-readable storage medium

The present disclosure provides a method for adjusting an input virtual keyboard and an input apparatus, which are directed to solve the problem of one-hand operation in existing input virtual keyboards. The method comprises: based on a received keyboard floating instruction: adjusting a size of an input window to a screen size; intercepting a click event performed on a touchscreen by a user and detecting the click event; and when the click event is detected as a keyboard adjustment instruction, based on the keyboard adjustment instruction, adjusting at least one of a drawing position and a drawing size of an input view, wherein the input view is a region for drawing the input virtual keyboard in the input window.

Method for adjusting input virtual keyboard and input apparatus

A transducer includes a housing, a magnet unit, an elastic diaphragm, a vibration unit, and a coil. The housing has a first housing and a second housing to form a storing space. The magnet unit is secured in the first housing. The elastic diaphragm is a thin layer and disposed between the second housing and the vibration unit. The spiral coil is mounted on the vibration unit and has two electrical connecting points for inputting electric signal of alternating current. Hence, the coil can generate continuous vibration caused by alternating attraction/repelling force of the magnet unit. When the frequency of the electric signal is within 20&#x2dc;20000 Hz, the elastic diaphragm generates sound signals within earshot. When it is within 10&#x2dc;20 Hz, it can generate vibration signals. So, signal unit can produce sound and vibration. In addition, it saves space for effectuating the thickness minimization of a product.
