2.The results show that in the top of crown,the bifurcation ratio increases with the age from 1 a to 12 a,it comes to maximum at 12 a,then keeps at a comparative high level.
3.She was a "reincarnate level 145," having undergone dangers and hardships to win her crown and sit astride a dragon covered in sparkling, flaming scales.
4.Some xerophytic arbor and bush restored obviously with the change of habitat. Correspondingly, the groundwater level, vegetation coverage, diversity of biology, the species richness and crown of Populus euphratica all changed.
5.The extraction of Sr￣(2+)and Cs￣+ in simulated high level radioactive liquid waste with crown ethers is studied by the radioisotopiac trace,The first extraction rate of Sr￣(2+)with 0.01mol/l dicyclohexyl-18-crown-6 in 1,1,2,2-tetrachloroethane and trichlo romethane is more than 90%.
