| 3. | Infiltration and solidification remelting of molten aluminum in a centrifugal force field 高温铝熔液在旋转多孔介质内的渗透与瞬态固化和再熔过程 |
| 4. | For solution with certain compositons , it behaved as the growing temperature tg . when tg . is too high , the film was hard to grown or did n ' t grow well 而对于确定r值的熔液,则主要表现为过冷度的选取,也即生长温度的选取。 |
| 5. | Previous to this invention , all flat glass was cut from cylinders or disks of blown glass , but now the metal was poured directly from the pot onto an iron table and flattened with an iron roller 在这一发明前,所有的平板玻璃都是从吹制玻璃的圆柱体或圆盘上切割下来的,现在则是将玻璃熔液直接从熔化罐倒在铁板上,用铁棍压平。 |
| 6. | By high - temperature solution technique , the pmnt , pznt single crystals with perovskite structure were successfully prepared and the crystals showed size from 0 . 5mm to 5mm , and color from light yellow to brown . 2 采用高温熔液法成功地制备出钙钛矿相结构的pmnt 、 pznt单晶材料,制备的pmnt 、 pznt单晶颗粒大小多为0 . 5mm 5mm之间,晶粒呈淡黄色,少数呈灰褐色。 |
| 7. | For the exist of al2o3 particles in the front of the interface between solid phase and liquid phase changing the thermal diffusion conditions , the evolution of ultimate microstructure of the composites was like as the solidification of single - phase alloy 5 .熔液温度较低时,以单向凝固为主,熔液温度较高时,以等轴凝固为主。最终凝固组织的演变类似单相合金的凝固组织演变。 |
| 8. | In this paper the formation mechanisms of needle - like mullite in porcelain bodies were discussed , and nesulted in a new forming mechanism of mullite . it is indicated that the melt is necessary condition to forming needle - like mullite in porcelain bodies 通过对瓷坯中二次针状莫来石形成机理的讨论,提出了新的二次莫来石形成机理,并说明了熔液是二次莫来石形成的必要条件。 |
| 9. | Moreover the effects of the temperature of molten copper and the content of al powder in the mixed - powder on microstructure and properties ( hardness , conductivity ) of the material were studied . the results indicated that : 1 本文采用反应铸造法制备了cu - al _ 2o _ 3复合材料,并分析讨论了熔液温度和混合粉末中al含量对制备cu - al _ 2o _ 3复合材料的性能(硬度、电导率)和组织的影响。 |
| 10. | Have evolved deep under the oceans at hydrothermal vents , where volcanic fluids rich in reduced chemicals served as an energy source , or in shallow geothermally heated waters on earth s surface , where these chemicals or sunlight could have provided an energy source for 这类生物可能在深海中的热液火山口处演化,那里的熔液含有丰富还原化学物,提供了生长和复制所需的能量又或在地球表面受地温加热的浅水处演化,从阳光或水中的化学物中攫取能源。 |
