Three types of scanning strategies, including the chessboard scanning strategy, the zigzag scanning strategy and the remelting scanning strategy, were conducted to study the effects of scanning strategies on surface morphology, microstructure, mechanical
采用水热合成的方法,在玻璃基底上制备了氧化锡纳米棒阵列,利用X射线衍射仪(XRD)和扫描电子显微镜(SEM)对其晶体结构和表面形貌进行表征,并解释了氧化锡纳米棒的生长机理。为了找到最佳的制备测试参数,研究了室温下,不同水热合成时间和退火温度对纳米氧化锡乙醇气敏特性的影响,并在此基础上研究了365 nm紫外光激活时氧化锡对乙醇气体的气敏特性,与无光照时对比。结果表明,室温下,水热合成反应6 h,500 ℃退火时,氧化锡纳米棒阵列对乙醇气体显示了较高灵敏性,365 nm紫外光照射时,氧化锡气体灵敏度比无光照时
关于1970年初气动激光器公开发表以来研制情况的第一个详细报告是由海军军械试验室小安德森(J. D. Anderson, Jr.)等于一月份在美国星际航行与航空学会讲演时给出的。
借助许多生物标本,在对激光辐射进行研究时,我们证明小能量的激光束具有刺激作用;同样已经反复证明,较大能量的激光具有抑制或破坏作用;此外,可以证明,逐次辐照具有积累效应。在1968年和1970年的慕尼黑外科医生会议上,我们已经报告过这方面的情况。
We develop a numerical scheme to construct the scattering (S) matrix for optical microcavities, including the special cases with parity-time and other non-Hermitian symmetries. This scheme incorporates the explicit form of a nonlocal boundary condition, w
This study was conducted to understand the cellular proliferative effect of Photobiomodulation Therapy (PBMT) on thawed dental pulp stem cells (DPSCs) stored for 2 years. For this purpose, cells were exposed to PBMT for short period of time to evaluate th
