Increase ofvapor of atmospheric tower and sidetrack vapor extraction an also leads to rise ofoverall evulsion ration .

Lanthanides belong to the sixth cycle of the periodic table Ⅲ B family, are all solid metal, they are La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, holmium, erbium, thulium, ytterbium, and lutetium were 15 kinds of metals and their periphery are two layers of electronic 5d16s2, while the peripheral third layer f orbital but never zero to 14, so the external electronic structure of 4f0-145d16s2, and therefore these elements in oxidation number are to 3, very close chemical properties, extraction, when it is difficult to separate them they are mostly multi-element mineral mix, more difficult to increase refining, and their atomic number of 57-71, one by one to increase the number of protons the nucleus, and thus extranuclear electron of gravity is also growing, so that atomic radius decreases with increasing atomic number Z, which makes lanthanides contraction, ionic radius is also reduced, which also makes Zr, Hf, Nb and Ta, Mo and W, the atom and ionic radius very close to each other they also determine a similar nature, resulting in difficult separation, also the tribe Ⅷ of the fifth cycle, ruthenium, rhodium, palladium, and the sixth cycle, osmium, iridium, platinum is very similar in nature, thus The six elements, said platinum group elements.

The results show that the cultivated land area in Wanzhou will slightly decreased while the construction land will slightly increased,forest land will increased dramatically,and it is difficult to improve the ecosystem service value by single increasing the wetland area.Grassland ecological restoration and increasing orchard area will improve the ecosystem service value by comprehensive treatment of geological hazards and soil loss.The ecosystem service theory value in Wanzhou is 11.89 billion yuan each year,the correction value is 10.64 billion yuan each year,and the present value is 9.65 billion yuan each year.This shows the ecological restoration has good economical efficiency.The optimization of land use structures based on ecosystem service value could satisfy the development of social economy with land demand,and realized the benefit of ecology and economy inphase,the study supported a new way to solve the key technical problem in land use programming in China.
