Abstract: Disclosed is a screening method for adsorbent in environment-friendly gas-insulating equipment, the method steps include: establishing screening sets, pre-experiment screening, standard gas adsorption experiments screening, mixed gas adsorption experiments screening, establishing mapping relationship between the decomposed gas type set and the third adsorbent type set under different working conditions, and selecting adsorbent combination mode suitable for the working condition type and the mixed gas composition mode based on the mapping relationship. Through adsorption experiments of a single standard gas and a mixed gas under different working conditions, an adsorbent combination mode suitable for adsorbing mixed decomposed gas under different working conditions is obtained; at the same time, in view of the situation that the suitable adsorbent has not been screened through the adsorption experiment, the suitable adsorbent is further screened with the molecular dynamics theory, so that all the adsorbent combinations suitable for different working conditions can be obtained.

Abstract: A method of calculating the potential sliding surface of the progressive failure of slope is provided, which is also abbreviated as a failure angle rotation method. The method performs the search calculation of the potential sliding surface of the slope to determine the potential sliding surface, under the assumption that the geological material failure satisfies the condition of the angle between the maximum shear stress surface and the minimum principal stress axis corresponding to the critical stress state being (45° +φ/2), and based on the fact that the principal stress directions at different positions are rotated while the slope is applied different external loads and gravity loads. The failure path is varied with the change of the stress during the failure process to perform the solution for the potential sliding surface of the slope based on numerical calculation.
