Abstract: A self-driving vehicle test method, apparatus, and system are provided, and relate to the field of self-driving technologies. The system includes a software control module, a motion control module, and a plurality of motion platforms. The software control module may obtain information about a first test scenario, and send the information about the first test scenario to the motion control module. After receiving the information about the first test scenario, the motion control module may determine a test motion platform and a target motion platform from the plurality of motion platforms based on the information about the first test scenario, and send parameter information of each determined motion platform to the motion platform, so that the motion platform performs a corresponding operation based on the parameter information. In this way, a self-driving vehicle can be tested without participation of test personnel, thereby improving test efficiency and reducing labor costs.

Abstract: A riser reactor for fluidized catalytic conversion process consists of a prelift zone, a first reaction zone, a second reaction zone with enlarged diameter, an outlet zone with reduced diameter along coaxial direction form bottom to top, and the end of the outlet zone connects to a horizontal tube. The reactor is used for adjusting different operating conditions to process single or plural feedstock in each different reaction zone for producing the desired product.
