Abstract: A shear testing system and method of thermo-seepage-mechanical field and engineering disturbance coupling under deep and complex condition are provided. The shear testing system can be used in conjunction with an axial pressure application device to simplify the structure, save costs, and facilitate a triaxial confining pressure—temperature—axial pressure—torsional shear coupled test on a rock specimen. The shear testing system can achieve the following three purposes. First, the shear testing system can convert an axial pressure into a torsional shear force through a transmission mechanism of a power conversion assembly. Second, the shear testing system can apply an axial pressure to the rock specimen fixed between two specimen fixing heads, through a pressure shaft of an axial pressure mechanism. Third, the shear testing system can apply a triaxial confining pressure and a temperature field to the rock specimen.

Abstract: A low-heat-loss operation method of a line-focusing heat collection system and the line-focusing heat collection system are provided. The method includes the following steps. Solar energy is utilized to preheat a collector tube in an empty tube state, so that the collector tube is in a preheating mode. After a set preheating temperature is reached, a heat transfer working medium is injected into the collector tube. In the injection process of the heat transfer working medium, an injection section of the collector tube is converted into a focusing mode from a preheating mode. After heat collection is finished, the circulation of the heat transfer working medium is stopped, and the focusing mode of the collector tube is kept. In the drainage process of the heat transfer working medium, an emptying section of the collector tube is converted into a light heat-tracing mode from a focusing mode.
