Abstract: Disclosed are a heat dissipation apparatus and an electronic device. The heat dissipation apparatus includes a first cooling plate, provided with a through hole arranged to be connected to an inlet pipe and an outlet pipe; a second cooling plate, with a heat dissipation cavity formed between the first cooling plate and the second cooling plate and in communication with the through hole; and a retractable floating component, connected to the second cooling plate for floating heat dissipation of the second cooling plate.

Abstract: A method of identifying tobacco carbonyl components using non-targeted mass spectrometry is disclosed, which includes the following steps: (1) preparing a tobacco sample extract; (2) derivatizing (part of) the sample/extract with 2,4-dinitrophenylhydrazine (DNPH); (3) derivatizing (another part of) the sample/extract with DNPH-d3; (4) mixing the derivatized tobacco samples; (5) preparing blank samples; (6) performing ultra performance liquid chromatography (UPLC) and ion trap (Orbitrap) high resolution mass spectrometry (HRMS) on the (derivatized) tobacco samples; (7) processing the LC-MS data; (8) filtering the mass spectrometric characteristic data to retain final chromatographic peaks; and (9) structurally annotating or identifying the retained final chromatographic peaks to obtain the tobacco carbonyl components.

Abstract: Methods, apparatuses, systems, computing devices, and/or the like are provided. An example method may include a printer assembly. An example printer assembly may include a printer ribbon drive mechanism. An example printer drive mechanism may include a drive wheel, a connector, a spring, and an actuator. An example actuator may be configured to translate from a first axial position to a second axial position. An example spring may be configured to apply a greater force when an actuator is disposed in the first axial position than when the actuator is disposed in the second axial position. The example method may also include a motor to apply a torque to a drive wheel.

Abstract: A test system and a test method for a lip sticking force of tipping paper for cigarettes are provided. The test system includes an artificial lip and test equipment. The artificial lip is a silica gel block. The test equipment includes a friction meter testing platform, a force measuring sensor, a rigid rope, a pulley, a pulley bracket and a sample loading module. The pulley is installed on the pulley bracket, and the rigid rope slides in the pulley. The rigid rope is L-shaped, a first end of the rigid rope in a horizontal direction is connected to the force measuring sensor, and a second end of the rigid rope in a vertical direction is connected to the sample loading module. The artificial lip is located directly below the sample loading module, and the artificial lip is in contact with the sample loading module at a test position.
