This work mainly studies the structure of cryolite in the high temperature.The paper is divided to double parts.

本论文主要研究冰晶石在高温状态下的物质结构问题，论文分为两部分，第一部分研究了高温状态下冰晶石(Na3AlF6)的物质结构问题，我们采用自制的加温炉体进行了室温300K到1075K的在位拉曼测试，记录了样品从室温到熔融状态下的峰位及半高宽的变化。

An increase of stirring speed and a decrease of amount of alumina in each addition will shorten the complete dissolution time of alumina in the molten cryolite bath, which can meet the requirement of point feeding in the modern aluminium electrolysis cells.

搅拌速度的提高和氧化铝每次加入量的降低可以缩短氧化铝在熔融电解质中的完全溶解时间，这符合现代铝电解槽点式加料的需要。

The increase of crystallite size and notable changes of orientation factor for crystal planes during blow molding process reveale.

利用DSC和W AXD研究了医用聚丙烯专用料及其密封式直立吹塑瓶的熔融行为和结晶结构。

Ethylene-Propylene copolymers and mixtures with long E-P sequence structures were investigated using WAXD and PLM methods. As the content of Cs reached more than 30 mol %, the (140),(130) crystal planes appear at 2θ= 20 in X-ray diffraction patterns of me-Itcrystallized samples.

用广角X-射线衍射和偏光显微镜方法，研究了具有乙丙长序列乙丙共聚物及其共混物，发现通过熔融慢冷结晶样品，C3含量在30mol％以上，衍射角2θ=20°处出现了属于γ-PP晶型的(140)，(130)晶面衍射。

During the cold crystallizing process, when PBT component was above 20%, the existence of PBT promoted the cold crystallizability of the blends. While during the melt crystallizing process, the addition of a second component restrained the crystallization of the system.

在冷结晶过程中，当PBT含量超过20%时，将促进体系的结晶性能；而在熔融结晶过程中，第二组分的加入抑制了体系的结晶性能，当配比为50/50时，结晶速率相对最低。

The longer the soft segments the better the mobility of the softsegments, and the better the crystallizability of the soft segments.

当软链段分子量超过6000后，软链段结晶的完善程度虽然比均聚物差，但结晶能力对硬链段含量的变化已不敏感，其结晶所需过冷度、熔点和熔融热焓在所考察的硬链段含量范围内基本保持不变。

Thermal behavior of PTT/PBT blends are studied. The results suggest that the presence of the less crystallizable PBT molecules in the PTT-rich (or PBT-rich) blends decreases the crystallizability and crystalline temperature of the blends. The complicated phase morphology of the PTT/PBT blends is strongly dependent on the compositions of the blends.

研究了PTT/PBT共混体系的热行为，以PTT为基质相的共混物，另一次要组分的加入降低基质相的结晶能力和共混物的熔融温度。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
