Abstract: The present disclosure relates to a subtle cornea deformation identification method and device based on a pixel-level corneal biomechanical parameter, including the following steps: step 1, sampling and analyzing a dynamic video of corneal stress deformation in a historical database, and calculating pixel-level data; and step 2, configuring an ensemble classifier based on a sampling result and detecting a local change in corneal biomechanics, thus identifying a subtle cornea deformation. The present disclosure has high measurement accuracy and is capable of detecting a local subtle biomechanical change.

Abstract: A high-speed machining tool made of a steel-bonded carbide and a method for preparing the same relate to the technical field of lathe tools made of steel-bonded carbides, and overcome the problems of traditional steel-bonded carbide lathe tools about low hardness and low toughness. The high-speed machining tool includes a skeleton, a main body, and a coating. The main body is consolidated by the skeleton from inside. The skeleton and the main body are both ringlike in shape. The main body has its outer surface covered by the coating. The high-speed machining tool is such made that the skeleton is hard and the main body is tough. The blade of the tool is hard and can transfer vibrations to the main body, thereby protecting the tool from brittle fractures and improving the overall performance of the tool.

Abstract: A method for assembling a dual-head pulling rod involves attaching pulling heads to two ends of a rod body through threaded connection using a system that includes a foundation, on which a rod dispensing device, an inclined guiding plate, a conveying flap, a head dispensing device, a head mounting unit, a clamping device, an assembling device and a V-shaped output channel are provided. The inclined guiding plate is inclined and uses its ramp to guide a rod body falling thereon. The conveying flap is swingable between an input position and an output position. The conveying flap at the input position receives the rod body coining from the inclined guiding plate and outputs the rod body to the clamping device.
