In fact, the total energies for the possible metastable alloy phases of A〓B and AB〓 types of six possible structures were calculated as a function of their lattice constant to find out if the respective metastable phases of A〓B or AB〓 types could be relatively stable in the selected systems. The calculation not only predicted the possible metastable states but also the lattice constant of the corresponding metastable alloy phases of either FCC or HCP structures.

In Atlantis which existed 10,000 to 14,000 years ago as Earth measures time, Atlantean humans were mostly white and related to the Anu, a Pleiadian family that came to Earth to strip mine her of gold, and their slave nation, who lived upon the land known as Europe today.

在1万-1万4千地球年前的亚特兰蒂斯，亚特兰蒂斯人大部分是白人并相关于Anu人（一个来到地球掠取地球金矿的昴宿星家庭），以及相关于Anu人的奴隶族的（他们生活在今天所知为欧洲的大陆上）。

The above method can be used as a general method of determining molecular weight distribution of polymers.4.Solid-state ~1H wide-line NMR and ~(31)p magic angle spinningNMR were applied to a series of PEI/DNA complex samples with different PEI molecular weights and nitrogen/phosphatemolar ratios,in order to disclose the influence of various structural factors on the interactions and morphology.The results of ~1H NMR spectra showed that the linewidth of the PEI signal was greatly broadened with increasing the N/P ratio.Meanwhile,in the ~(31)p M_AS experiment,the signal was found to shift upfield with the increase of the N/P ratio.Both ~1H and ~(31)P NMR experiments demonstrated that the interaction between two constituents and subsequently the morphology of the complexes vary with the N/P ratio.

首次将固体核磁共振应用到聚合物/DNA复合物体系，观察复合物体系中不同N/P比对其相互作用和相结构的影响，研究表明N/P比的变化对聚乙烯亚胺/DNA基因递送体系分子水平上相互作用有着很大的影响；另外，还发现不同分子量的聚乙烯亚胺聚合物载体在N/P比为3的情况下对复合物中DNA的微观尺度没有明显影响；通过氢的自旋扩散实验，首次测得在PEI/DNA复合物体系中DNA相尺寸的大小，并发现在体系中N/P比达到3以上的复合物中DNA和PEI达到了分子水平上的相容。

The results show that the main metastable phase of glass 20BaO15Ga_(2)O_(3)65GeO_(2 ) is BaGa_(2)Ge_(2)O_(8), but that is BaGe_(2)O_(5) when BaF_(2) is substituted totally for BaO in the glass.

In addition, molecular orientation behaviors induced by shearing, electric field and magnetic field were investigated. The space group of the monomers A3EO7 and A9EO7 were determined as P2〓2〓2 and P112/m by means of electron diffraction and X-ray diffraction. Liquid crystalline properties of the monomer and the polymer were studied using DSC, variable X-ray diffraction, TEM and polarized optical microscope. Both monomers exhibit monotropic liquid crystalline behavior, and they also give a metastable phase on the cooling process. The polymer PA9EO7 shows enantiotropic liquid crystalline properties. Thus the rigid polymer backbone is not a fatal defect that completely distorts the packing arrangement of the mesogenic moiety in the side chain liquid crystalline polyacetylene.
