| 1. | At 200v of substrate negative bias voltage and 300w of rf power , the content of cubic phase in bn films reaches 92 . 8 % 当负偏压为200v ,功率为300w时,薄膜中立方相的含量达到92 . 8 。 |
| 2. | Preparation of hexagonal moo3 by phase transition in the water and electrochemical properties of lithium intercalation into the oxide 水溶液中相转化制备六方相三氧化钼及其电化学嵌锂性质 |
| 3. | 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。 |
| 4. | Combining the resu1t of l { alnan spectra , we reach the conclusion that the crysta1 qua1 i ty of 2 # sall1p1e is better than that of 1 # sample , afld 3 # samp1e is the worst 结合raman的测量结果我们得出2 #材料的晶体质量比1 #的好,而立方相的3 #样品质量最差。 |
| 5. | As with chiyou ' s farigxiang , the traditional belief in door - god in chinese society results from of the primitive thought which is predominated by law of mutual permeability 摘要中国传统民间的门神信仰,和蚩尤“方相”的文化现象一样,是互渗律支配下初民的原始思维的产物。 |
| 6. | The xrd peak of 2 6 = 45 ? was gradually widened with the increasing of pt . it might mean that rhombohedral phase was gradually converted to tetragonal phase in this system 在pmn - pt系统中,随着pt含量的增加, 2 = 45的xrd特征峰出现明显峰宽化现象,表明pmn - pt由三方相逐步向四方相转化。 |
| 7. | The crystal phase of as - deposited znte ( znte : cu ) films depends on the cu concentration in znte . znte films with un - doped cu and low cu doped ( 2 . 98 % ) show cubic phases with preferred orientation of ( 111 ) . heavily cu - doped films exhibit a mixture of cubic and hexagonal phases 刚沉积的znte ( znte : cu )薄膜的晶相结构取决于薄膜中的掺铜浓度,未掺铜和低掺铜( 2 . 98 )的薄膜为立方相,重掺铜( 9 . 9 )出现六方相和立方相的混合相。 |
| 8. | Abstract : cruise missiles have the characteristics of concealment and unexpectedness , so effectively detecting cruise missiles is the crux of cruise missiles defence . in order to increase detecting distance and discovery probability for cruise missiles , we ought to synthetically utilize various measures to make up the all directions target detecting and information communicating system with emphasis , which combines air with ground , far with near , advanced measures with traditional measures 文摘:巡航导弹具有隐蔽和突然的特点,对巡航导弹进行有效的探测,是抗击巡航导弹的关键,综合利用各种手段,组成空中与地面相结合、远方和近方相结合,先进手段与传统手段相结合的全方位、有重点的目标探测与报知体系,可增大对巡航导弹的探测距离,提高发现概率。 |
| 9. | It has been found that all the elements in the addition act respectively in the way that affect the material ' s properties during the calcining process and the increase of the pms / pzn ratio can weaken the stability of the crystal structure of the sintered ceramics and cause the crystal structure transformation from the tetragonal to the rhombohedral as well 发现多元压电陶瓷材料中,无论是主加组元还是微量掺杂,预烧阶段,它们在陶瓷中的作用都表现为单独离子对陶瓷结构和性能所起的作用。烧结后,随着pms pzn相对量的提高,陶瓷晶体结构由四方相向三方相转化,同时稳定性下降。 |
