Since the most sensitive resonance lines of nonmetallic elements are situated in vacuum ultraviolet region （below 190 nm）, they can not be directly determined with a common AAS instrument covering the spectral range from 190 to 700 nm. The molecular absorption spectrometry is often used for the determination of nonmetallic elements. Syty et al. used vapor molecular absorption spectrometry（VMAS） to determine the sulfur dioxide and sulfide, in which a hydrogen hollow cathode lamp was used as a continuum source to determine SO;at 210 nm and a deuterium arc

刮板由于其较复杂的结构,在模锻过程中常存在折叠、局部填充不足、欠压及裂纹等缺陷。实践表明,锻造过程中坯料与模具温度的控制不当、坯料与毛边槽设计不够不合理,导致金属流动困难是造成缺陷的主要原因。借助有限元仿真软件Deform,通过对刮板模锻成型的模拟分析,可以提供金属材料流动、模具填充、毛坯与模具温度变换等工艺分析数据。研究表明,Deform软件的应用,可有效地避免锻造缺陷的发生、提高材料利用率、减少试锻次数,对此类锻件的生产有很强的参考价值。

采用丝网印刷法在氧化铝陶瓷表面制备了活性Mo-Mn金属化层,研究了Mo含量对烧结后金属化层的微观结构、元素成分以及钎焊后抗拉强度的影响。研究结果表明,Mo-Mn法陶瓷金属化层以Mo为骨架结构,玻璃相填充于骨架结构内部,随着膏剂中Mo含量的增加,烧结后的金属化层中Mo骨架与玻璃相成分并无较大变化,而Mo骨架体积占比增加,玻璃相体积占比相应减少。烧结过程中陶瓷和金属化层二者玻璃相之间相互迁移,陶瓷玻璃相向金属化层中迁移深度可达20μm以上,玻璃相中Si元素在金属化层表面存在一定程度的偏析现象。50wt%、70wt%和85wt%Mo含量膏剂制备的金属化层平均抗拉强度分别为110 MPa、120 MPa和111 MPa,表明Mo含量为70wt%时封接性能最佳。

采用离子束辅助沉积方法在95%(质量比)Al2O3基板上制备Cu薄膜,利用热氧化法使Cu薄膜氧化,并与Al2O3基板反应,制备出CuAl2O4薄膜。通过X射线衍射仪、扫描电子显微镜、能谱仪和X射线光电子能谱仪分别对CuAl2O4薄膜的结构、成分和微观形貌进行了表征。研究结果表明,大气环境下,热氧化温度低于1000℃时,薄膜主要成分为CuO,随着热氧化温度的提升,薄膜成分比例并无较大变化,但是薄膜晶粒在不断增大;热氧化温度为1000℃时,氧化后的Cu薄膜与Al2O3基板开始反应形成CuAl2O4晶体。当热氧化温度为1100℃时反应更加完全,形成纯度较高的CuAl2O4薄膜,且薄膜晶粒尺寸明显增大,薄膜表面Al元素含量增加。

The single spores were isolated from chlamydospores of Ustilaginoidea virens with three different maturities by PSA. The isolated single spores were cul- tured on different media at different temperatures under natural light for inducing conidia to explore the optimum isolation technique of single spore and optimum cul- ture condition of conidia. The results showed that the successful isolating rate of single spore from yellow rice false smut balls reached 90.00%. The sporulatina quantities of isolated single spores cultured on PSD and PDB media at 22 -29 ~C （variable temperature under natural light） or 28 ℃ （constant temperature under dark condition） for 12 d were up to 6.3× 107 and 1.1× 106 spore/mL, respectively. PSA was the most effective method to isolate single spores from yellow rice false smut balls of U. virens. The optimum conidia culture condition included PSD or PDB medium, 22 -29℃ or 28℃, natural light and vibration culture. Key words Ustilaginoidea virens; Single spore isolation; Conidia; Culture condition

针对现有模型未考虑当DEM空间分辨率R和平均剖面曲率V各自趋向于0时,地形描述误差Et亦趋向于0的缺陷,提出了DEM地形描述精度的幂函数定量模型。通过对地形描述误差与DEM空间分辨率和平均剖面曲率之间定量关系的研究,采用非线性最小二乘拟合方法,得到DEM地形描述精度的定量模型为:RMS Et=0.005713R1.056V0.9431。实验和对比分析表明,所提出的定量模型具有较好的拟合精度,同时对高分辨率的DEM地形描述误差估算具有更好的泛化精度,在生产实践中具有更好的实用性。
