Mainly reflected in kinematics/dynamics analysis, collision analysis, virtual training, virtual maintenance, and other aspects. The current status and trends of standardization development in ergonomics and virtual reality technology 2.1 The current status and trends of standardization development in ergonomics will introduce the main standardization organizations engaged in ergonomics and standardization work as follows: TC159, a human ergonomics standardization technology in the standardization organization (ISO), has carried out effective work in its professional field, formulated a large number of standards, and has a total of 78 standards so far. In recent years, the focus of standard development has mainly been on WG5 (Software Ergonomics and Human Computer Dialogue) and WG6 (Human centered Design Process in Interactive Systems) in SC4. The European Union Standardization (CEN) has established the Ergonomic Standardization Technology (TC122) and continuously adjusted its Working Group (WG) according to the trend of technological development. At the same time, the EU actively participates in the activities of the standardization organization's ergonomic standardization technology, integrates with the standards, and strives to have ISO/TC159 adopt its standards and work projects. In recent years, more energy has been focused on the standard revision of WG5 human-computer interaction. The US Department of Defense has established the Human Machine Engineering Technical Advisory Group (DoD HFETAG).

Solar batteries are the application of 'storage batteries' in solar photovoltaic power generation. Currently, there are four types of batteries used: maintenance free lead-acid batteries, ordinary lead-acid batteries, colloidal batteries, and alkaline nickel cadmium batteries. The widely used solar energy batteries in China are mainly lead-acid maintenance free batteries and gel batteries. These two types of batteries are suitable for reliable solar power systems, especially unmanned workstations, due to their inherent "maintenance free" characteristics and less pollution to the environment.

When the plating solution fails, the EAST UPS power supply EA820H power frequency machine 20KVA is diluted with a large amount of water and discharged into the wastewater tank. There are no strict requirements for the loading capacity of plating solution. Store in a cool and sealed place for quality assurance. The shelf life is eighteen months. How to prevent rusting of iron wire and how to handle it after rusting? Iron can rust over time and is prone to rusting due to its active chemical properties, as well as external conditions. Moisture is one of the substances that makes iron prone to rusting. However, the presence of water alone will not cause iron to rust. Only when oxygen from the air dissolves in water and reacts with iron in a water environment, will a substance called iron oxide be formed, which is called rust. The use and maintenance life of solar batteries is more than 5 times longer, and the charging temperature range is wider.

Surface strengthening of the main forming components of the mold is carried out to improve the wear resistance of the mold parts and thus enhance the quality of the mold. For surface strengthening, different strengthening methods should be selected according to the molds used for different purposes. Punching dies can be strengthened by electrical discharge, hard alloy welding, etc., to improve the wear resistance and compressive strength of the surface of the mold parts; Steel parts for hot working molds such as die-casting molds and plastic molds can be treated with nitriding (hard nitriding) to improve their wear resistance, heat fatigue resistance, and wear corrosion resistance; The deep drawing die and bending die can be treated with sulfur infiltration to reduce the friction coefficient and improve the wear resistance of the material; Carbonitriding (soft nitriding) can be applied to the surface strengthening treatment of various molds. In order to ensure that TI components have the best possible performance and structure, reasonable processes, and lower costs, the following principles should generally be followed when selecting electronic materials. According to the performance parameters of TI components, use materials first. Different occasions have different requirements for the performance of electronic components, and all materials (dielectric materials, conductive materials, and encapsulation materials, etc.) should be selected according to these requirements, based on the structural characteristics of the components. Due to the different purposes and usage environments of electronic components, their structural methods vary greatly. Capacitors and resistors used at high temperatures require a fully sealed structure. In this case, in addition to selecting dielectric and resistance materials, appropriate encapsulation materials should also be considered. Reduce the usage of solar cells (can be charged at low voltage).
