The invention discloses an electronic measurement method and a terminal. The electronic measurement method comprises the following steps: when the measuring command is received, entering a measuring mode according to the measuring command, and displaying a first scale for a user to measure on the first edge of a terminal screen; when a rotation command is received, displaying a second scale subsequent to the first scale on a second edge adjacent to the first edge of the screen according to the rotation command. By adopting the electronic measurement method and the terminal, the terminal can be taken as a measurement tool for measuring the distance or the angle, so that great convenience is brought to use.

The invention discloses a method for overhauling a side bearing plate of a main frame of a train by by positioning an overhead contact line with a special tooling, the special tooling is two identicalpositioning measuring units, The specific methods are as follows: At first, that eight side bear plates are arrange in a predetermined position, Install the two positioning measurement unit frames onthe main frame and adjust the tooling, Check the dimensions of the 4 locating pins, After meeting the dimensional parameters, the side bearing plate is fixed on the mounting bracket of the positioning measurement unit from the back through the locking pin and the locking nut, the side bearing plate is fixed and the dimensions of the four locating pins are re-checked, after meeting the dimensionalparameters, the side bearing plate is welded, after cooling, the side bearing plate is checked again, and after meeting the dimensional parameters, the tooling is removed and entered into the subsequent process. The method solves the problems of time-consuming, labor-consuming, difficult measurement, poor dimensional accuracy and flatness in positioning and assembling the side bearing plate of the JJC main frame by improving the existing positioning method of the side bearing plate of the JJC main frame, and greatly improves the production quality and efficiency.

The invention discloses a display panel and a display device. The display panel includes: a face recognition module, including an infrared light source and an infrared sensing unit; a light-shielding layer, the light-shielding layer is located on the side of the infrared sensing unit close to the display surface of the display panel, and the light-shielding layer has an imaging light-transmitting hole, and the imaging light-transmitting hole and the infrared Corresponding to the sensing unit, wherein the imaging light-transmitting hole includes at least two kinds of imaging light-transmitting holes with different diameters. The invention can realize the face recognition function and also has the measurement function.

The invention provides a pair of scissors with the head tip telescopic function. The pair of scissors comprises a body, holding parts and heads, wherein the holding parts and the heads are arranged at the two ends of the body. The heads are provided with head tips. A containing cavity used for containing the head tips and a spring component placed into the containing cavity are arranged inside the body, wherein the spring component is used for retracting the head tips into the containing cavity or pushing the head tips out of the containing cavity. The pair of scissors with the head tip telescopic function has the advantages of being simple in structure, convenient to use, safe to carry and the like.
