The maxima of low-temperature internal friction peaks plot a symmetrical peak-like curve at logarithmic frequency spectrum and the peak-like curve shifts toward high frequencies with the increase of heating rate, indicating that phase transition relaxation time decreases; the maxima of high-temperature internal friction peaks exhibit a linear relation to the reciprocal frequencies, and as the heating rate increases its slope rises, which implies that the heating rate drives the normal movement of phase interface further in low-frequency measurements.

低温内耗峰峰值与对数频率呈现峰形函数关系，随升温速率的增加，频率峰向高频方向移动，相变弛豫时间减小；高温内耗峰峰值与倒数频率成直线关系，随升温速率的增加，直线斜率变大，表明低频测量时升温速率对相界面法向运动的驱动作用更强。

Furthermore, we believe that the general rules for understanding the superstructures formed within boundary areas are correlated directly with different overlapping or connecting operation with respect to building units of flattened hexagons and P-B polygons. These rules are as following:I The adjoined domains at least have their basic structural units a side-shared (that is, sharing two column clustersП) The basic structural units in both domains have overlapping area as large as possible.3 For theξ-Al-Ni-Rh phase formed in the as-cast Al75Ni15Rh10 alloy, phase transition processes induced by electron beam irradiation with different amount of dose were studied by in-situ observations in an electron microscope.

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.
