Abstract: Disclosed is an efficiency analysis method for an intelligent interaction system, including: obtaining user information and behavior data generated during execution of user commands, and associating the user information with the behavior data to obtain associated data; preprocessing the associated data, selecting efficiency indicators for the intelligent interaction system based on standard indicators, and classifying the preprocessed associated data according to the efficiency indicators to obtain classified data; formulating efficiency scoring criteria based on expert opinions, and obtaining efficiency scores of the classified data by using the efficiency scoring criteria; and determining weights of the efficiency scores by using an objective weight assignment method, and evaluating the efficiency scores through fuzzy comprehensive evaluation based on the weights to obtain comprehensive scores.

Abstract: A microdialysis system includes: an input device, first and second connecting pipelines and a flow feedback device that includes a connecting needle, a liquid collecting tank, a calibration weighing module, and a flow feedback control display module; the weighing module weighs the liquid in the liquid collecting tank regularly according to conditions and a program set in the display module and transmits a measured liquid weighing value to the display module; the display module performs a difference operation between the current liquid weighing value and the previous liquid weighing value to obtain a weighing sampling difference value, compares the weighing sampling difference value with a preset value to monitor whether the connecting needle outputs liquid normally, and further feeds back a flow state of fluid in the first and second connecting pipelines. In the microdialysis system, the flow state of each connecting pipeline is monitored by weighing the collected liquid.

Abstract: The present disclosure provides a parking interaction method and apparatus, a storage medium, an electronic device and a vehicle, and belongs to the field of vehicle technologies. The method includes: outputting and displaying a currently-generated virtual parking image and a corresponding real parking image; receiving a parking space selection instruction for the virtual parking image, where the parking space selection instruction includes first position information of a to-be-parked target available parking space in the virtual parking image; according to a correspondence between the virtual parking image and the real parking image, determining second position information of the target available parking space in the real parking image; according to the first position information, highlighting the target available parking space in the virtual parking image, and according to the second position information, highlighting the target available parking space in the real parking image.

Abstract: Disclosed are a testing method, a system and a device for flicker fusion frequency range. The testing method comprises: taking end point values of a self-preset range as starting judgment values; acquiring a flicker judgment result of a subject; if the flicker judgment result is flickering, continuing to execute the acquisition step by increasing a judgement value until the flicker judgment result turns into non-flickering, and defining a judgement value at the moment of turning as an judgment valueup; if the flicker judgment result is non-flickering, continuing to execute the acquisition step by decreasing a judgement value until the flicker judgment result turns into flickering, and defining a judgement value at the moment of turning as an judgment valuedown; and acquiring a flicker fusion frequency range which takes a judgment valueup and a judgment valuedown as end point values.
