Abstract : a device used to test the thermo - shock resistance performance of mosi2 heating element was introduced . and the designing methods of hardwares and softwares were related emphatically 文摘:介绍了一种单片机控制的二硅化钼发热体耐热冲击性能测试台的研制办法,并着重阐述了测试系统硬件和软件的设计方法。
The heat - reaction characteristics of ni / si and tin / ni / si structure and the regularity for forming the nisi film have been studied deeply and formed the excellent ni - salicide shallow junction diode 文中对ni si和tin ni si的热反应特性以及nisi薄膜的形成规律进行了详细的研究。制备了优质的ni硅化物浅结二极管。
Auger e1ectron spectroscopic measurements indicate that the intermixing between the deposited er and the substrate si atoms ieads to the formation of ersi , with the outermost surface terminated by si atoms Auger电子能谱( aes )测量结果表明,由于互扩散机制的作用,退火中反应形成的饵硅化物的最外层原子是硅原子。
Though some properties of anode materials such as nitrides , silicides , oxides and alloys are better than that of carbon materials , they are still unsatisfactory from the viewpoint of application 氮化物、硅化物、氧化物和合金等负极材料虽然在某些性能方面强于碳材料,但是从实用的角度而言,还存在着一些不如意的地方。
On the other hand , ultra thin er silicide films are formed on si ( 00l ) substrate by room temperature deposition of 3 to 20 ml er atoms followed with the subsequeni in situ annealing 对铒硅化物超薄层表面结构的进一步研究是在上述工作的基础上展开的。室温下在硅( 001 )表面淀积了3至20单层的饵原于,并加以退火处理。
Methods a randomized , controlled prospective clinical trial was carried out in 60 patients admitted in the department of neurosurgery , who required long - term use of an indwelling urinary catheter 方法将需要留置导尿病人随机分为全硅橡胶及硅化乳胶导尿管两组,每组各为30例,分别检测尿常规、记录留置导尿管期间病人的感觉。
2 . from the si and er core ievel spectra and the si valence band spectrum a rather detailed description of the er / si ( 00l ) interface formation is presented . the following results can be extracted 2铒硅( 001 )界面、表面及铒硅化物最初形成过程研究首先利用同步辐射光电子能谱方法研究了室温下铒在硅( 001 )表面的淀积和退火过程。
