| 1 | Textures and Magnetic Properties of Grain Oriented ElectricalSteel Produced by Cross Shear Rolling显示文摘Commercial grain oriented electrical steels were made by cross shear rolling (CSR) with a chosen mismatch speed ratio 1.1. Original sheets of 0.75 mm thick, which had been produced by conventional cold rolling and intermediate annealing were rolled to thickness from 0.35 mm to 0.15 mm, and followed by industry annealing. The deformation texture and the magnetic properties were measured. Results indicate that: in the condition of the CSR, the deformation texture of rolled sheet is generally similar to that of conventional rolled sheet; for sheets with the thicknesses from 0.35 mm to 0.25 mm, favorable deformation textures, mainly consisting of {111} <112>, are also found at subsudece layers, which may help produce sharp Goss texture, and after the final annealing, the magnetic properties of sheets are not lower than that of conventional rolled | Liu, Gang Qi, Kemin Sun, Jianlun Zuo, Liang Liang, Zhide Wang, Fu

| 3 | A Microcomputer Fitted Method for Determination of the True ODF of Hexagonal Materials according to the Maximum-Entropy Estimate显示文摘A method which is especially suitable for microcomputer calculation of the true orientation distribution function(ODF) according to the maximum-entropy estimate is proposed for hexagonal system polycrystalline materialswith physical symmetry.The resultant computational software system has been also designed and first carried outin a microcomputer PANAFACOM-U1200 being on line with the X-ray diffractometer D/max-3A.The simu-lated calculation shows that the method is concisely pragmatic and easily popularized,while the results obtainedare trust worthy. | Liqing CHEN Fu WANG Zhide LIANG Dept.of Materials Science and Engineering,Northeast University of Technology.Shenyang,110006,China | 1993 | Journal of Materials Science & Technology1993，9，1： | 1 |
| 4 | Determination of the Concentration of Chlorella vulgaris Beij by Visible Spectrophotometer显示文摘[Objective]This study aimed to provide technical parameters for large-scale production and industrial development of Chlorella vulgaris Beij.[Method]By using 721 visible spectrophotometer,the transmitted light intensity of different concentrations of C.vulgaris liquid under different wavelengths was measured to normalize the absorbance data,thus determining the optimal wavelength for the growth of C.vulgaris and the concentration of C.vulgaris liquid under the optimal wavelength.The regression equation of absorbance at the optimal wavelength and C.vulgaris concentration was obtained to derive the formula between equivalent concentration C and transmitted light intensity I,thus calculating the equivalent concentration of 0.25-fold C.vulgaris liquid under different transmittance.[Result]The transmitted light intensity of C.vulgaris reached the peak at 670 nm,indicating that 670 nm is the optimal wavelength for measuring C.vulgaris concentration.The regression equation between absorbance and C.vulgaris concentration was y=-1.479 7+0.987x,with a correlation coefficient of 0.991,suggesting a high correlation between these two factors.The formula of equivalent concentration C and transmitted light intensity I was C=-ln(I/I0)/LK,where L indicates the optical path length(cuvette width)and K indicates the average cross-sectional area of C.vulgaris cells.[Conclusion]It is feasible to investigate indirectly the concentration of C.vulgaris with a spectrophotometer,which can be used to determine the optimal dehydration time of C.vulgaris. | Zhixu ZHAO Jingyang PAN Liangbo WU Wei ZHANG Junsheng XU Yugui CHEN Zhide FU | 2015 | Agricultural Biotechnology2015，4，2： | 0 |
| 5 | 类风湿关节炎与牙周炎的可能关联性:系统评价与Meta分析显示文摘目的:已有研究表明类风湿关节炎(Rheumatoid Arthritis.RA)的患者对牙周炎的易感性更高.但独立研究的结果仍存在争议。本篇Meta分析的目的是综合评价RA和牙周炎的关联性。材料和方法:在PubMed和EMBASE进行系统性文献检索。用标准表格提取数据.并计算每项研究的优势比(OR)和95%可信区间(CI)。采用固定和随机效应模型估计适宜的合并数据。结果:本研究共纳入八项病例一对照研究。各研究纳入范围从104例到151.569例。RA患者的牙周炎患病率为15.5%~100%.而对照组牙周炎患病率为10%~82.1%。在第一组(对照组)和第二组中.异质性分别为38%和11%。采用固定效应模型分析.第一组和第二组的牙周炎总合并ORs估计值分别为4.68(95%CI:3.11—7.05)和1.28(95%CI:1.24-1.33)。结论:本篇Meta分析表明RA和患牙周炎的总体风险增加显著相关。 | Qingqin Tang Haitao Fu Baodong Qin Zhide Hu Yaoting Liu Yan Liang Lin Zhou Zaixing Yang Renqian Zhong 成宵(译) 滕伟(审) | 2018 | 中国口腔医学继续教育杂志2018，21，4： | 0 |
