    Abstract: A high-throughput and small size samples tension, compression, bending test system is disclosed. The system includes a computer unit, a motor and a number of the sample testing modules mounted horizontally or perpendicular to that ground on a workbench. The sample testing modules include a sample testing modules base plate fixedly attached to the workbench, and a ball screw, a displacement sensor, a moving beam, a clamp unit, a linear moving platform unit and a force value sensor arranged on the sample testing modules base plate. A number of the sample testing modules are arrange in parallel on the workbench or uniformly distributed in a circumferential direction with a point on the workbench as a circular center.

    Abstract: A measurement deviation correction method and system for spark discharge analysis of a large-size metal material includes: performing line-by-line scanning measurement on a surface of the material to obtain a line component content, performing in-line correction on the line component content by adopting a line linear fitting model, and performing inter-line correction by taking a total average value obtained by eliminating an extreme value from a line component content distribution to obtain an inter-line corrected component content; performing column-by-column scanning measurement on the surface of the material to obtain a column component content, performing in-column correction on the column component content by adopting a column linear fitting model, and performing inter-column correction by taking a total average value obtained by eliminating an extreme value from the column component content; and coupling the inter-line corrected component content and the inter-column corrected component content to obtain an optimal measurement component content.
