Transformer fluid directly affects the working state of the components and the cooling efficiency of transformer.There are three kinds of transformer fluid used Double Boilers for electric locomotive, EMU and suburban rail vehicles: mineral oil, silicone liquid and synthetic ester based insulating oil.In this paper, the three kinds of oil are compa
Nowadays, China has developed over 38,000-km high-speed railways (HSR).As one of the key elements in the HSR system, continuous welded rail (CWR) enables higher transportation efficiency, while demands for more robust inspection and maintenance techniques.The discrimination between longitudinal temperature force and longitudinal additional force is
Solar sails are propellantless systems where the propulsive force is given by the momentum exchange of reflecting photons.In this study, a self-deploying Swivel Glider Accent Chair system based on NiTi shape memory wires and sheets has been designed and manufactured.A small-scale prototype of solar sail with carbon fibre loom has been developed.Dif
The emergence of intentional communication and the intentional presentation of objects have been highlighted as important steps in the ontogeny of cooperative communication in humans.Furthermore, intentional object Double Boilers presentation has been suggested as an extremely rare form of communication evolutionarily.Research on comparable means o
