The experiment results indicate that higher phase splitting speed and extraction factor can be achieved when low-carbon alcohols such as n-butanol are used as organic solvents; by using five different N-carbobenzyloxy-L-amino acids as chiral ligands that are formated with Cu(superscript 2+) or Ni(superscript 2+), it is found that as a ligand, Z-Phe has a low extraction factor, while Z-Hyp, Z-Pro, Z-Glu, Z-Val have higher extraction factors, and among these, Z-Val has the highest distribution coefficient; pH value of extractant, when near to the PI of phenylalanine, helps to improve extraction resolution effect; temperature has no obvious effect on the resolution result.

There are complicated difficulties in Plantinga's theory. In this essay, I start from the 4th factor of warrant : leading to truth, pointing out that under certain circumstance, this factor will demand the recogniser to distinguish truth and false. This demand is in conflict with the distinction of de jure question and de facto question, meanwhile it is not coherence with the externalism position insisted by Plantinga.

Transcription factors can control the transcription of their target genes when they bind to the DNA-binding sites on their promotors. They can transfer the messages of growth factors and so on to those effective molecules. Core binding factor al is such a kind of transcription factor, which can control the differentiation of osteoblasts peculiarly. They can induce the pro-osteoblasts or non-osteoblasts to synthesize and secrete most mineralize related proteins such as ALP, OC, OPN, BSP and so on, in order to differentiate to osteoblasts finally.

In the dissertation, a new stabilization method, equal-density method was adopted to prepare modified asphalts with storage stability at high temperature. In this method, a compound was prepared by premixing polymer and filler, and the compound was mixed with asphalt to prepare Polymer-Modified Asphalt by changing the ratio of polymer and filler. The asphalts with good storage stability were formed with the addition of filler, by regulating the density difference between polymer and asphalt. With identifying the effect of composition factor and the technique conditions on mechanical properties of polymer/filler compound and the molecular distribution of the polymer, identifying the effect of composition factor and the technique conditions on the properties and structure of polymer/filler modified asphalt, Styrene-Butadiene-Styrene copolymer, Low Density PolyEthylene, Styrene-Ethylene-Butadiene-Styrene block copolymer modified asphalts with good storage stability and performance were prepared. Rheological method, gel content analysis and swelling measurement were adopted to elucidate the interaction between the polymer and filler. Filler reduced the difference between the polymer and asphalt with the premixing technique, which led to the improvement of the storage stability of the modified asphalts. The thermo-oxidative aging process of base asphalt and PMA were studied and the effect of antioxidant additives on the base asphalt and PMA were analyzed.
