Preparation of the cathode includes:shaping under the press of 40Mpa, sintering at 550℃for 1 hour and at 900℃for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100℃and for 2 hours at 300℃. Partial pressure of oxygen which need lower than 5.11×10-7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally successfully designed a satisfied one and the results show that the equipment can be satisfied the requirment of the experiment. Flow of the inert gas is 1.5L/min, the voltage is 2.8 V, temperature is 850℃and time is 2 hours during pre-electrolysis. Flow of the inert gas is 0.2L/min, the voltage is 3.1 V, temperature is 900℃and time changes with the mass of TiO2 during electrolysis, namely the greater need the longer time; To eliminate influence of salt and other impurities, the products need to wash with distilled water and dilute chlorhydric acid , then wash with dilute hydrochloric acid under supersonic wave assistant. Finally, electrometical properties of the electrolysis of TiO2 is researched by cyclic voltammetry and chronoamperometry, and results show that there are two main reodox steps, namely from TiO2 to TiO and from TiO to Ti.

The result showed that Imperata cylindrical, Digitaria sanguinalis, Erigeron acer Xanthium sibiricum and Hedyotis auricularia are the species with high tolerance to heavy metal pollutions adapted to the adverse conditions of wastelands. These species can be used as pioneer plants for recovety of the vegetation in the manganese-mined wastelands. The individual event pollution index of the heavy mentals, compared to their background values are higher than 2, with Pb as an exception, indicating that the soil in these areas has been contaminated and that Mn and Cd are the elements creating most serious pollution problems.

The creative point of this dissertation consists firstly in that monochromatic stimuli instead of combined spectral power distribution were used as visual object, and spectral luminous efficacy curves were drawn from the performance-based method; Comparison between performance-based method and brightness-matching method was then done and therefore connection between these two methods was developed; One more creative point is that the analysis based on the theory of neurophysiology and psychophysics leads to the conclusion that contribution of the colour channel during visual information processing is reflected from performance-based method, which should be considered when CIE develops the new mesopic photometry system.
