查询词典 X ray

X-ray radiography, X-ray radioscopy and X-ray computed tomography were performed to the C preforms and C/SiC composites made by chemical vapor infiltration method. Elementary research of the simulation of X-ray nondestructive testing of C preforms and C/SiC composites was conducted. The main contents and conclusions are summarized as follows:(1) The equivalent absorption coefficients of graphite and SiC to Al (KAl/sic, KAI/C) were measured. It was found that in 35-45KV, KAl/sic=1.1~1.2 and KAl/c=0.08~0.12. That means X-ray radiography was much less sensitive to fiber defects than to SiC matrix. It was suggested that Al Image Quality Indicator would be used to evaluate the quality of X-ray radiographs of C/SiC.

本文选择X射线照相、X射线实时成像和X射线CT等三种方法对C纤维预制体及C／SiC复合材料进行了检测和研究，并对C／SiC复合材料X射线检测的计算机模拟做了初步的探索，主要研究内容和结果如下：(1)测定了C和SiC的X射线照相等效系数，在35～45KV的条件下，Al对SiC的等效系数K_为1.1～1.2，Al对C的等效系数K_为0.08～0.12，所以X照相射线检测C／SiC对C纤维缺陷不敏感，而对SiC基体缺陷敏感。

But really, whether you label her as the New DIY Superstar, a Kate Bush for the iPod Generation, or simply the Next Big Thellong, it all amounts to the same thellong: she's a ruddy star.Last year she was one of the revelations of the South by Southwest Music Donference in Bustin, Texas.Thellos time she gave a performance that demonstrated that there was substance behellond the exotic surface. With the multi-genre melting-pot polyrhythms and dance-punk aggression of songs like "Warrior" and "We Know Bll Bbout U," the singer harkened back to the aggressively proto-feminist dance music of Grace Jones and X Ray Spex.

DIY超新星， iPod时代的Kate Bush，或是，简略地，下一个大人士，不管你怎样定义她，你都没有办法否定她是一个&该死&的名人上年，她成了德克萨斯州奥斯丁Southwest Music Donference的席上客这一次，她的表演证实，在她怪异的外表下，有着艰深的感情存在路程经过过程多类型大熔炉是的多旋律编排以及Dance-Punk式的急进歌曲如《Warrior》以及《We Know Bll Bbout U》等等，这位歌手带咱们回到了如Grace Jones或X Ray Spex一般，急进元祖女人主义的Dance音乐中去

The study about the flux and index of gamma-ray loud blazars show:(1)there is significant correlation between the luminosities in gamma-ray and VLBI radio energy band;(2)there are strong anticorrelarions among the observed indices of soft X-ray, hard X-ray and gamma-ray. For the FSRQs, the whole X-ray emission was contributed by synchrotron self-Compton emission, for the HBLs, the X-ray emission was dominated by synchrotron emission while the soft X-ray emission is dominated by synchrotron emission and the SSC emission dominate the hard X-ray energy band for LBLs;(3) there are strong radio-radio and radio-optical flux correlations for the quasar 3C 273. The higher frequency emission leads those in lower frequency. The multi-band complex indices strongly correlated with the high frequency flux which implies that the object is becoming bright when the energy spectrum is harden.

通过对γ噪Blazar天体的谱指数、流量的相关研究，发现（1）51个样本blazar的γ射线光度与VLBI光度之间存在显著相关；（2）软X、硬X以及γ波段的观测谱指数之间存在较强的反相关，对FSRQs，无论是硬X射线还是软X射线的辐射都是逆康普顿辐射的贡献，而对于HBLs来说，则是同步辐射的贡献，对LBLs，在软X射线波段以同步辐射贡献为主，在硬X射线能区以逆康普顿贡献为主；（3）3C 273的射电各个波段以及光学之间存在强相关，高频辐射一直领先低频辐射，3C 273的多波段复合谱指数和高频流量之间存在强的反相关，意味着当能谱变硬时对象变亮。
