Specifically, itcontains 8 chapters.In chapter 1, the formation, structures, properties and the futureprospect of liposome were thoroughly reviewed;In chapter 2, the stibility and permeability of phopholipid -eleostericacid liposome were studied together with the effect of polymerizationof eleostearic acid. This membrane system was very sensitive to 〓,the effect of 〓 was clarified to increase the aggregation/fusion ofliposomes and made the permeability of mixed liposomes much higher;In chapter 3, two polymerizable conjugated diyne bolaamphiphiles were synthesized. They could form very stable mixed liposome, andthe diyne could be polymerized by UV light in bilayer liposomes, as aresult, the stability of mixed liposome against solvent or surfactantafter polymerization were enhanced. In chapter 4, two kinds of amphiphilic amino acids were synthesized andstable liposomes were formed therefrom After the condensationpolymerization of amino acid in bilayer liposomes, stable polypeptide liposomes were obtained, which had lower phase transition temperatureand higher permeability.In chapter 5, four kinds of glycolipids were synthesized and theiraggregation behavior in water was comparied. When incorporated intophospholipid bilayer membranes, they could increase the phase transitiontemperatures and inhibit the aggregation and fusion of mixedliposomesat lower temperature.In chapter 6 and 7, three kinds of steroidal bolaamphiphiles withdifferent chain lengths were synthesized. Incorporation of steroidalmoiety to the center of lipid bilayer membrane obviously increased themobility of lipid membrane and shifted Tc to lower temperature side incomparasion with cholesterol. The bolaamphiphile which was shorter thanthe hosted lipid bilayer membrane thickness influenced the lipid packingmore obviously.

The assembly of two trimers within this hexamer is very similar to that of C-phycocyanin and R-phycoerythrin hexamers, but the tight level of the assembly of two trimers within this hexamer is clearly not so much as that of C-PC and R-PE hexamers.

Lithologies are mostly sand and carbonate rocks, caps are mud rock, shale and magmatite. Entrap types are anticline, fault block rebuilt by breaking and the screened entrap diapered rock mass. The composition is CO_2, N_2, CH_4, C_2H_6 and He etc. It is magma air source body and its geologic fashions are intrusion and buried volcanic conduit. The relations between gas reservoirs and gas source bodies have three types: magma intrusion-breaking-communicated gas reservoir, magma intrusion-contacted CO_2 reservoir and buried volcanic conduit-contacted gas reservoir. The CO_2 migration in magma intrusion is consisted of fusing and crystallizing phases;it in volcanic conduit is consisted of near-surface effusion and crystallizing phases.The buoyancy of CO_2 in water far more than migration resistance in breaking or chink, CO_2 is easy float upward, the floating can results in differentiation of different density gases and concentration of sealed gas. The gas in sand reservoir firstly migrate into the higher porosity and coefficient of permeability sand, and along with the pressure going up it migrate into the lower. In magma intrusion-breaking-reservoir migration, CO_2 firstly migrate into watered breaking, began gravity differentiation and concentrate, the gas pressure time and again go up, CO_2 migrate into reservoir and concentrate under expansibility as the pressure reach upward a given extend. The CO_2 in reservoir experience four breaking modes: chemistry deposition, dissolution, diffusion and mechanic breaking, the pressure balance can be broken by faulting and the CO_2 will further migrate and form new reservoir.
