1. The roasting is atmospherically leached under diluted acid, and the leaching rate of vanadic anhydride in the invention can reach over 82%.

2. Basic vessel, pressureless, constructed from steel with built-in butyl-rubber diaphragm across the entire cross-section for absorption of the expansion water when atmospherically separated.

3. Today cathodic protection of reinforced concrete is recognised by most authorities as a well-proven solution to corrosion of reinforcement in atmospherically exposed reinforced concrete.

4. The research done about the corrosion mechanism and measures of corrosion protection was mainly aim at industrial steel architecture and steel construction exposed atmospherically.

5. That the two boutiques, linked by a reflected-gold corridor, are so close physically and so distinct atmospherically prompted a simple division.
