为了进一步深入了解超高功率光纤激光深熔焊接过程中等离子体特征,试验拍摄了深熔小孔内外等离子体形态,并采用光谱仪检测分析了光纤激光致等离子体光谱信号.利用检测得到的等离子体光谱信号,计算研究了等离子体的电子温度、电子密度、电离度以及等离子体压力特征,并分析了在小孔内不同深度处及孔外等离子体的变化规律.结果表明,孔内等离子体呈现不均匀分布特征,孔外金属蒸气远多于等离子体.等离子体光谱分析显示,光纤激光致等离子体辐射出的谱线较少,即电离程度较低.进一步的计算结果同样证实了光纤激光致等离子体处于弱电离状态,但等离子体电子密度仍然处于较高水平,且等离子体瞬态压力可达到数百个大气压. 相似文献

Polymorph screening is currently one of the most important tasks for innovators and for generic companies from both pharmaceutical and intellectual property rights aspects. The hemihydrate form(Form Ⅰ) and formamide solvate(Form Ⅱ) of estradiol are isolated and prepared via systemic crystallization screening in this paper, and the formamide solvate form is reported for the first time. Both polymorphic forms were characterized by single-crystal X-ray structure analysis(SXRD), powder X-ray diffraction(PXRD), and thermal analysis(TGA and DSC). The PXRD experiments indicate that the samples in this study are the pure polymorphic forms via comparing the patterns with the simulated ones. The stability and equilibrium solubility data of the solid-state phase were also examined in order to check the impact of the differences observed in their crystalline structures. It has been found that Forms I and II are of conformational polymorph and Form II is the more thermodynamically stable solid form, while Form I possesses higher solubility, indicating its possibility as an alternate solid form for its further solid formulation development if necessary. 相似文献

Surface plasmon enhanced antireflection coatings for GaAs solar cells have been designed theoretically.The reflectance of double-layer antireflection coatings(ARCs) with different suspensions of Ag particles is calcu-lated as a function of the wavelength according to the optical interference matrix and the Mie theory.The mean dielectric concept was adopted in the simulations.A significant reduction of reflectance in the spectral region from 300 to 400 nm was found to be beneficial for the design of ARCs.A new SiO2/Ag-ZnS double-layer coating with better antireflection ability can be achieved if the particle volume fraction in ZnS is 1%-2%. 相似文献

A GaSb crystal incorporated with Mn has been grown by the Bridgman method on the Polizon facility onboard the FOTON-M3 spacecraft. Structural defects and growth striations have been successfully revealed by the chemical etching method. By calculating various parameters of the convection, the striation patterns can be explained, and the critical value of the Taylor number, which characterizes the convective condition of the rotating magnetic field induced azimuthal flow, was shown. The stresses generated during crystal growth can be reflected by the observations of etch pit distribution and other structural defects. Suggestions for improving the space experiment to improve the quality of the crystal are given. 相似文献

为了加快颗粒全息图的重建速度,提出了一种基于多线程编译框架(OpenMP)和统一计算设备架构(CUDA)并行技术的二级并行架构颗粒全息图快速重建方法。第1级并行针对重建截面,第2级并行针对像素,同时在这两个维度进行并行重建,利用OpenMP实现图片级并行,利用CUDA实现像素级并行。以煤粉颗粒全息图为测试对象,同时采用单线程重建程序和二级并行重建程序进行全息重建,比较了两种计算方式的重建结果和计算耗时。结果表明,二级并行重建结果与单线程重建结果是一致的,且可大大缩短重建耗时; 对于分辨率为5000×5000的全息图,在重建截面数为40时,可实现48.3倍的加速比。此计算架构在数字全息的颗粒场实时在线诊断中具有很好的应用前景。 相似文献
