This invention specifically discloses a test device for testing the reflective performance of traffic road markings. The device includes a test chamber, with an asphalt road sample placed at the bottom. Reflective road markings are applied to the road surface, and a drainage device is provided on the side of the asphalt road. An environmental simulation device and a road marking light-sensing test device are respectively installed above the road markings to be tested. The environmental simulation device consists of a heating device, a cooling device, a raindrop device, and a friction device, simulating the effects of different environmental and vehicle factors on traffic markings. The road marking light-sensing test device consists of a sliding block, a rotating shaft, an illumination lamp, and a retroreflection coefficient measuring instrument. This invention can simulate complex environments such as wet-dry cycles, wheel friction, and alternating hot and cold temperatures on the road markings on the asphalt sample. Finally, the data received by the retroreflection coefficient measuring instrument is used to analyze the reflective performance of the road markings, thus more realistically reflecting the reflective performance of traffic road markings.

This invention discloses a device and method for evaluating the self-healing performance of CCUS well cementing. In this device, a liquid injection unit and a gas injection unit are respectively connected to the cavity of a reaction vessel. A data acquisition unit is connected to the reaction vessel and collects relevant parameters within the reaction vessel's cavity. The data acquisition unit is connected to a data processing unit. A control unit is connected to both the data processing unit and the data acquisition unit. Self-healing cement samples and ordinary cement samples undergo pre-damage treatment. Then, breakthrough pressure tests are performed on the self-healing pre-damaged samples and the ordinary pre-damaged samples, respectively, to obtain the breakthrough pressure of the self-healing sample and the breakthrough pressure of the ordinary sample. If the breakthrough pressure of the self-healing sample is greater than that of the ordinary sample, the self-healing cement sample is judged to have the ability to self-heal microcracks. This invention is reliable in principle, convenient to operate, has a reasonable structure, and the testing process is simple and quick.

The embodiment of the invention discloses a data processing method and device, a computer readable storage medium, electronic equipment and a computer program product. In the process of upgrading the first product selection engine to the second product selection engine, the product selection capability of the second product selection engine to be applied to the online environment of the commodity information service system is verified, and the first product selection engine is the product selection engine currently applied to the online environment. The method comprises the steps of obtaining identification information of a plurality of historical item selection sets through data backflow, calling a first item selection engine and a second item selection engine by taking the identification information as parameters, and obtaining commodity information of a first commodity and commodity information of a second commodity recalled by the first item selection engine and the second item selection engine from commodities provided by a system; and taking the commodity information of the first commodity as a reference, performing consistency judgment on the commodity information of the second commodity, and when the commodity information obtained according to the identification information of the plurality of historical commodity sets is correspondingly matched, determining that the commodity selection capability verification of the second commodity selection engine is passed. And many problems existing in manual sampling inspection are solved.
