With the continuous improvement of 5G standards, 5G network equipment of global mobile operators has become mature. China's railways take 5G as a new generation of mobile communication technology for railway dedicated network, the R&D of railway application equipment is under way, and the 5G-R equipment interoperation test needs to be started urgently to provide conditions for the deployment of future 5G-R system. Based on the system architecture of 5G-R network and the theory of interoperation test, this paper presents the test architecture of 5G-R interoperation, innovatively puts forward one test method named the building block to set up processes for the verified 5G-R system described in the test architecture. According to the building process of the building block method, this paper lists the interoperation test interface and key test content of the test interface for the equipment to be tested, offers the design process of the interoperation test specification and the test framework of interoperation static and dynamic test environment.

To explore the shear creep characteristics of weak inter layers under repeated rain action, the Permian carbonaceous shale soft interlayers in southwestern China were taken as the research object, and the real-time infiltration water/air pressure cyclic shear test system was used to carry out the infiltration water/air pressure test system. In the cyclic shear creep test, the shear creep characteristics and long-term strength deterioration mechanism of the weak interlayer were analyzed, and a creep damage constitutive model considering Weibull distribution was established. The results showed that; l) The weak interlayer has obvious creep characteristics. With the increase of the number of permeating water/air pressure cycles, the shear deformation before failure gradually increases, showing two different failure modes, toughness, and brittleness during failure; 2) With the increase of water penetration/The increase in the number of air pressure cycles, the deterioration degree of the weak interlayer shows an increasing trend, but eventually tends to a certain value, the degree of deterioration can be expressed by the function Di = 0.7717 X [1-exp(-0.1n)]; 3) Based on the experimental data, a damage viscoplastic element based on the Weibull distribution theory is proposed, and a water/air pressure cycle creep damage model is constructed, which can well describe the three stages of creep of a weak interlayer. The research results have important guiding significance for the long-term stability analysis of high and steep slopes with weak interlayers. [ABSTRACT FROM AUTHOR]

Unmanned swarm test evaluation is an important bridge that promotes unmanned swarm technology from theory to practice. Compared with traditional combat systems, unmanned swarm systems have the characteristics of autonomous coordination, emergence of capabilities, and intelligent countermeasures. These have greatly exceeded the scope of traditional combat system test evaluation. In response to the abovementioned practical needs， this paper summarizes the groundbreaking work of advancing swarm test evaluation in the United States and China, and discusses the concept and development status of unmanned swarm test evaluation. Based on our previous research on aviation swarm operations, we also explore the main content and feasible technical route of unmanned swarm test evaluation, which will lay the foundation for the information upgrade and intelligent transformation of military equipment.

Major automakers follow their in-house standards to finish the testing and appraisal of interior textiles used in their vehicles. Those testing standards are much alike, but certain disparities exist in the aspect of testing equipment, relative conditions, methods and reference indicators. Primary testing items and performance testing standards for automotive textiles carried out by vehicle companies at home and abroad are well introduced in this paper for the benefit and reference of interior textiles suppliers. Hopefully, China could fasten her pace on the way to build a systematic and conclusive testing system for interior textiles. [ABSTRACT FROM AUTHOR]
