The present disclosure provides a test system and method for an anchoring performance of a full-size rock mass anchor bolt under combined load and relates to the technical field of detection test equipment. The system includes a primary frame, a co-directional pull-twist loading mechanism and a vertical shear loading mechanism. The primary frame includes a dual-parallel horizontal reaction frame and a vertical reaction frame. The co-directional pull-twist loading mechanism and the vertical shear loading mechanism are arranged in synergy with the primary frame. The co-directional pull-twist loading mechanism performs synchronous pull and twist loading for the anchored rock mass and the vertical shear loading mechanism applies a static load or simulates a dynamic load disturbance. The co-directional pull-twist loading mechanism and the vertical shear loading mechanism perform separate loading. By using the test system, anchor bolt pull test, pull-twist test of the anchor bolt body, pull-twist-shear test of the anchor bolt body and test of the anchor bolt and the anchored rock mass are performed and also a coupled load of pull, shear and twist is performed on a same anchored fracture surface to effectively test the comprehensive mechanical performance of the anchor bolt member in the rock mass under combined stress.

Machine learning application deployment using user-defined pipeline

Systems and methods are disclosed that relate to graphically representing different components (e.g., software modules, libraries, interfaces, or other blocks of code) that may be included in an application, linking the components in an ordered sequence to embody the application, and deploying the application to perform a task. The components may be displayed and represented as graphical components in a graphical application editor, or any other development environment. The graphical application editor may perform various operations with respect to the graphical components and the components respectively represented by and corresponding therewith. The operations may include facilitation of linking implemented instances of the graphical component objects together and/or developing the application by linking the underlying code associated with the graphical component objects according to the linking of the graphical component objects.

Method for analyzing and recognizing stable carbon isotopes of bio-based, petroleum-based and mixed plastic

The present invention relates to the field of isotope analysis and recognition of high polymer materials. A method for analyzing and recognizing stable isotopes of bio-based; 5 petroleum-based and mixed plastic includes the following steps: pretreating plastic products made of bio-based; petroleum-based and mixed plastic; determining stable carbon isotope ratios and carbon percentage contents of the plastic products by means of elemental analyzer-stable isotope ratio mass spectrometry; determining stable carbon isotope ratio characteristics and carbon percentage contents of the bio-based; petroleum- 10 based and mixed plastic; and drawing a confidence interval scatter diagram according to the carbon isotope ratio characteristics and the carbon percentage contents of the bio- based; petroleum-based and mixed plastic; and determining a differentiation range of the bio-based; petroleum-based and mixed plastic. The bio-based; petroleum-based and mixed plastic can be effectively differentiated by using the method. 15
