This project was established based on the first cooperative development of optical in situ real time detecting technique probing the atomic scale layer-by-layer epitaxy growth of oxide film. Over the last three years, we have given full play to the advantages and characteristics of both sides and have finished the assumptions and plans of this subject satisfactorily. 1. In Institute of Physics, we set up advanced oblique-incidence reflectivity difference equipment and wrote one data acquisition procedure that made the simultaneous detection of optical signal and RHEED signal into reality. 2. The first observation of sustained oscillations over hundreds of monolayers in both real and imaginary signals during the epitaxy growth of SrNb0.1Ti0.9O3 on SrTiO3 substrate in LMBE testifies that oblique-incidence is an excellent method to detect and monitor film epitaxy growth real time. 3. For the first time, we verify that oblique-incidence reflectivity difference method can be used to monitor the layer-by-layer growth mode during continuous growth through the correspondence between optical signals to atomic or molecular step edge density on the growth surface. 4. Phenomenological analysis shows that optical signals comprise three parts, the first is proportional to the average thickness of the film and depends on the bulk phase dielectric response; the second is proportional to the coverage of terraces and depends on the dielectric response of atoms or unit cells in the terrace; the third is proportional to the coverage of step edges and depends on the effective dielectric response of atoms or unit cells at step edges. This makes oblique-incident reflectivity difference technique a quantitative macroscopic method to monitor film growth.

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.

A new theoretical model, the 2CLJDQP potential function, was developed for linear molecules, which takes into account dipole, quadrupole and induction effects as well as the rotation of the dipole out of the molecular axis. The energy parameters were optimized for various types of fluids. With the modified mixing rules, the potential parameters obtained from homonuclear molecules can be used to calculate the second virial coefficients of heteronuclear molecules. The model was also successfully extended to triatomic molecules. Analysis of the contributions to the second virial coefficients of long-range interactions shows that the molecular interactions introduced in the present model, such as, the induction effects, cannot be neglected.

In this study, genetic analyses were conducted to determine the genetic basis in an elite resistant inbred line Siyi with complete resistance to maize dwarf mosaic. A new genetic model, two dominant complementary genes conditioning the resistance, were found by Mendelian genetic analysis based on parents, F1, F2 and backcrosses in three successive years' field trails. The two genes were further mapped near the centromere of chromosome 3 and 6, respectively by tightly linked microsatellite markers using 242 plants from F2 generation. The resistance gene on chromosome 3 is 1.0 cM apart from the flanking markers phi053 and umc1527, respectively. Whereas the linkage distance between two flanking markers bnlg1600 and phi075 and resistance gene on chromosome 6 was 1.0 and 4.0 cM, respectively. Genotypic analysis of the plants from testcross and F3 populations supported the new genetic manners.
