| 4. | In this thesis , solid state synthesis method was employed to prepare the orthorhombic layered limno2 , with homogeneous structure 本文使用固相法合成出晶体结构较为均一的斜方相层状limno2材料。 |
| 5. | No evidences of low - temperature phase transition were found for pbtio3 , while the tetragonal - orthogonal and orthorhombic - rhombohedral phase transitions were present for batio3 没有发现钛酸铅存在低温相变的证据,而钛酸钡则存在四方正交和正交三角铁电相变。 |
| 6. | In the orthorhombic phase , the desorption activation energy has an obvious increase with the increase of temperature , while it varies smoothly in the tetragonal phase as the temperature increases 当样品为正交相时,脱附活化能随着温度的升高明显增加,而四方相时则变化比较平缓。 |
| 7. | The limno2 synthesized by sol - gel method was orthorhombic phase and pmnm space group , with farthing impurity of mn2o3 。 the result of sem showed that the size of flake was about 1 ~ 2 m , the thickness of flake was about 50 ~ 100nm . the highest discharge capacity is 170 . 7mah / g 溶胶凝胶法所得limno2材料的xrd结果显示,该材料为斜方晶系, pmnm空间群,有极少量mn2o3杂质; sem结果显示其片层尺寸大约在1 ~ 2 m ,厚度大约为50 ~ 100nm 。 |
| 8. | The former was related to mn doping , both of p - carries supplied by la3 + or oxygen hole and n - carries induced by changing mn4 + into mn3 + can be locally displaced and simultaneously response with external electric field . , furthermore due to the overlaps between positive and negative carries . the latter was due to the phase transformation between orthorhombic and cubic , which was in fact the curie point 前者为la ~ ( 3 + )和氧空位等产生的p型载流子和mn离子变价引入的n型载流子在外电场下发生局域重排产生的载流子极化,且由于正负载流子的迭加效应所致,该介电峰与mn离子的掺入相关;后者为体系出现相应的正交与立方结构的转变所致,也即居里点。 |
| 9. | The conclusions are reported as following : the structure change of triuranium octaoxide ( u3o8 ) was studied by xrd at ambient atmosphere at temperature form 25 to 850 . there are two kind of phases of u3o8 in the temperature range studied , and the transformation temperature is about 300 . the low temperature phase is orthorhombic with space group amm2 , and it change to another phase with better symmetry around 300 主要的研究结果如下:对u _ 3o _ 8的相变和结构随温度的变化进行的分析研究结果显示:在300附近u _ 3o _ 8发生了相变,由底心正交结构(空间群为amm2 )的低温相转变为简单六方结构(空间群为p - 62m )的高温相。 |
| 10. | The 3d electrons increased with the content of mn doping increasing , and the electrical property increased accordingly as the electron transport path improved . it is confirmed that all the orthorhombic perovskite phase which is formed initially at the heat treatment temperature of about 600c and thoroughly above 850c are observed in the lcmto thin film deposited on si ( 100 ) substrate by rf magneto - controlled sputtering 确认了采用射频磁控溅射法于si ( 100 )基板上生长的薄膜至多在600热处理已开始形成晶相,形成的晶相全部是正交晶系钙钦矿相,提高热处理温度,薄膜中晶相含量相对增大,高于850后晶相基本形成完毕。 |
