Abstract: The present disclosure provides a method for displaying a three-dimensional space view. The three-dimensional space view includes a first three-dimensional space view and a second three-dimensional space view. The method includes presenting the first three-dimensional space view on a first user interface; presenting the second three-dimensional space view on a second user interface; changing the first three-dimensional space view according to a user input; and changing the second three-dimensional space view according to a change in the first three-dimensional space view.

Abstract: The present disclosure relates to a device and method for degrading chlorinated hydrocarbon (CHC) in polluted groundwater. A preparation method for each of glass tubes and the method for degrading CHCs are as follows: uniformly mixing 55-85 wt % of Bi2O3, 5-15 wt % of B2O3, and 10-30 wt % of SrCO3, putting into a corrosion resistant crucible, holding at 1,050-1,300° C. for 15-45 min, forming into a glass tube, and holding the glass tube at 200-400° C. for 1-3 h, followed by annealing; soaking the inner wall of the glass tube for 10-30 min with a HCl solution with a concentration of 0.02-0.2 mol/L, washing with water, and providing an ultraviolet lamp to obtain a self-cleaning glass tube; guiding CHC-containing groundwater to the self-cleaning glass tube, turning on the ultraviolet lamp, and carrying out ultraviolet irradiation for 1-8 h, thereby effectively removing the CHCs.
