The invention discloses a charging method and system for a split type process calibration instrument and a storage medium, and the method comprises the steps: S100, receiving the first current electric quantity of a calibration instrument host in a real-time and wireless manner through an operation terminal, and determining the second current electric quantity of the calibration instrument host; s200, according to the current power consumption of the current working mode, calculating a first working time length of the calibrator host by using the first current electric quantity, and calculating a second working time length of the operation terminal by using the second current electric quantity; s300, multiple times of time length comparison are sequentially executed; cyclically executing multiple times of time comparison; and S400, multiple comparison results are received, the operation terminal is immediately executed to reversely charge the calibration instrument host according to the comparison results, or the operation terminal is immediately executed to send a charging instruction to the calibration instrument host, so that the calibration instrument host reversely charges the operation terminal according to the charging instruction. According to the invention, the operation terminal and the calibration instrument host are mutually charged, and the power supply party and the power receiving party are automatically determined, so that the process calibration instrument has longer working time.

Light guide plate printing ink adsorptivity test method
InactiveCN104122383AMeet the needs of long-term useIncrease awarenessMaterial testing goodsTemperature stressLight guide
The invention provides a light guide plate printing ink adsorptivity test method. The method comprises the following steps: rising the temperature of an incubator, and carrying out thermal test on a light guide plate in the incubator; carrying out temperature stress testing on the light guide plate; scratching the printing ink surface of the light guide plate; carrying out light guide plate printing ink adsorption test; and carrying out printing ink appearance quality check on the light guide plate. The disadvantages of low adsorptivity and likely peeling of long-term used light guide plate printing ink can be found through the adsorption test of the light guide plate printing ink stimulating high temperature ageing and hot and cold impact, problem products can be effectively screened out, and a basis is provided for the selection of high-quality light guide plates for product exploitation.

Sign pen based on electronic lighting structure
The invention relates to a sign pen based on an electronic lighting structure and solves the problem that an existing sign pen is inconveniently used at night, a sign pen shell is wasted and the styleis old-fashioned. By using the sign pen shell, money of a consumer can be saved and the social resource can be saved, and the sign pen shell is also quite attractive and can bring a pleasant mood tothe user. A small bulb is arranged on the sign pen shell to meet the demand of using the pen at night by the public, so that satisfaction is found. The sign pen based on the electronic lighting structure is primarily technically characterized in that a small storage battery and the small bulb are arranged on the sign pen shell; the small storage battery is made from a special material and electricenergy gathered can meet the demand of long-term use by a writer, and the deficiencies of the existing sign pen are overcome. The sign pen based on the electronic lighting structure provided by the invention has the beneficial effects of being simple, convenient, low in cost and easy to popularize.
