| 1. | 3 and y or 8 phases are crystallized at the end . between them exists a pure phase region
晶锭的初始段为+两相区，末段为+或多相区，两段之间为单相区。 |
| 2. | The strength of shell was evaluated through observing the surface change after pressure by means of scanning electron microscopy . the melting point of the microcapsules was 24 . 7 c , nearly equaled to the pure phase change material
此种微胶囊中的相变材料在发生相变时具有调温作用，将其应用于室内墙体材料中，可使墙体材料具有自调温作用。 |
| 3. | The results of x - ray photoelectron spectrum ( xps ) demonstrated the ce ions in pure phase ce : yig ( x < 0 . 2 ) were in the state of trivalence . scanning electron microscope ( sem ) analysis showed conglobation of yig and ce : yig particles , whose size were smaller than 1 urn
Xps的分析结果显示单相ce ： yig ( x 0 . 2时)中ce离子是以正三价的状态存在，这与物相分析结果是一致的。 |
| 4. | And the initial capacity is higher than that of doped - monoelement . in addition , a new modified calcination method was first put forward that is pretreatment + annealing . pretreatment makes it more easy to obtain pure phase and annealing makes the partical size distribution more even
03时产物有较好的综合性能，比之单组元掺杂达到较佳性能时的掺杂量要减少，并且初容量升高，初容量为115m呐，第三次循环容量为114mah g 。 |
| 5. | Yig and ce : yig precursors were prepared via coprecipitation . by means of improving homogeneity and decreasing synthesis temperature , harmful yfeo3 phase was restrained , the oxidation of ce3 + was under control , and pure phase yig and ce : yig ( x = 0 . 2 ) were obtained
采用共沉淀法合成yig及ce ： yig前驱体，通过提高组分均匀性、降低煅烧温度等手段，有效地抑制了yfeo _ 3杂相的生成和ce ~ ( 3 + )离子的氧化，合成了单相yig和ce ： yig 。 |
| 6. | A new method was presented to prepare the composite phase change materials of paraffin and fatty acids for energy storage by intercalated composition . the process conditions were researched and the structure and properties were characterized . by xrd , ir and dsc . the obtained composite materials have good properties which the pure phase change materials did n ' t have
2 、提出利用插层复合法制备脂肪酸蒙脱土、石蜡蒙脱土复合相变贮能材料，对其制备工艺条件进行了系统的研究，利用xrd 、 ir 、 dsc等方法对其结构与性能进行了分析与评价。 |
