| 1. | 3 we for the first time prepared hbn - cbn mixed films with the hot filament assisted ecr cvd system 3首次利用热丝辅助ecrcvd系统制备了hbn七bn混合薄膜。 |
| 2. | Target material was hexagonal boron nitride ( hbn ) and working gas was pure argon 用射频溅射法在si衬底上制备立方氮化硼,靶材为hbn , 。工作气体为氩气。 |
| 3. | Here , we ' d like to re - emphasize the importance of participating ge health by numbers ( hbn ) program , which will bring you a healthy lifestyle 在此,我们将再次强调ge健康数字项目的重要性,倡导健康的生活方式。 |
| 4. | We discussed the effects of several variables in the experiment on the orientation of the films . the orientation mechanism of the bn films was also probed 1首次对hbn薄膜的取向生长进行了系统的研究,讨论了几种实验参数对取向的影响,探讨了薄膜取向生长机制。 |
| 5. | Boron nitride ( bn ) thin films were deposited on si substrates using the conventional radio - frequency ( rf ) sputtering system , with hexagonal boron nitride ( hbn ) target and working gas of argon ( or mixture of nitrogen and argon ) 使用射频溅射( rf )系统,靶材为烧结的六角氮化硼( hbn ) ,工作气体为氩气(或氩气和氮气的混合气) ,在硅衬底上沉积氮化硼薄膜。 |
| 6. | The results show that at a given substrate temperature , there is a compressive stress threshold , below which cbn phase is thermodynamically stable and p above which hexagonal bn ( hbn ) phase is thermodynamically stable 结果表明,在给定的衬底温度下,存在一个压应力阈值,压应力低于此值时立方相是热力学稳定相,压应力高于此值时,六角相是热力学稳定相。 |
| 7. | As hbn program has promoted , there are several factors contributing to healthy lifestyle : like exercise regularly , healthy eating , weight control , reducing cholesterol level , handling stress , quit smoking , and watch the alcohol , etc 正如健康数字项目所倡导的,健康的生活方式包括:适当的运动,良好的饮食习惯,控制体重,降低胆固醇水平,能应对各方面压力的良好的心理调节能力,戒烟,饮酒适度等等。 |
| 8. | 2 studying of the properties of cbn thin films afm showed that cbn thin film delaminated from substrate obviously . basing xps , we calculate the nib ratio to be 0 . 90 that is closing to unity , and the thickness of hbn layer on cbn layer that is about 0 . 80 nm 根据x射线光电子能谱,计算得到立方氮化硼薄膜中的n和b的原子数比为0 . 90 ,接近理想化学配比1 ;立方氮化硼薄膜顶层的六角氮化硼的厚度约为0 . 80nm 。 |
| 9. | A ) the orientation of hbn on si ( 100 ) was dominated intrinsically by the crystalline habit and the lattice mismatch between the substrate and films . the former was dominated by the periodical bond chain ( pbc ) theory , while the latter was in relation with the stress and strain A ) hbn在si ( 100 )表面的取向受hbn自身结晶习性和它与衬底间的晶格匹配关系的控制,前者是受周期性键链( pbc )理论控制,后者与应力和应变有一定关系。 |
| 10. | 1 successively depositing cbn thin films on si substrates which reaches international advanced level , the impact of negative substrate bias voltage and rf powers on the formation of cbn thin films were studied . boron nitride ( bn ) films were deposited on ( 100 ) - oriented p - type silicon substrate ( 8i sqcm ) with rf sputtering system . the target was hexagonal boron nitride ( hbn ) of 4n purity , and the working gas was the mixture of nitrogen and argon 研究了衬底负偏压和射频功率对制备立方氮化硼薄膜的影响立方氮化硼薄膜沉积在p型si ( 100 ) ( 8 15 cm )衬底上,靶材为h - bn靶(纯度达99 . 99 ) ,溅射气体为氩气和氮气混合而成,制样过程中,衬底加直流负偏压。 |
