魁北克的"存"与"亡" ——关于安妮·布里赛特的《寻求母语:翻译与文化身份》

安妮.布里赛特在其《寻求母语:翻译与文化身份》一文中,从政治与意识形态的角度探讨了魁北克戏剧翻译的研究,肯定了翻译在魁北克身份重构过程中所起到的独特作用。本文试图对此文中布里赛特的翻译思想进行分析和评介,以期对译学研究提供一些启示。     

Common variants at 11p13 are associated with susceptibility to tuberculosis

After imputation of data from the 1000 Genomes Project into a genome-wide dataset of Ghanaian individuals with tuberculosis and controls, we identified a resistance locus on chromosome 11p13 downstream of the WT1 gene (encoding Wilms tumor 1). The strongest signal was obtained at the rs2057178 SNP (P = 2.63 × 10(-9)). Replication in Gambian, Indonesian and Russian tuberculosis case-control study cohorts increased the significance level for the association with this SNP to P = 2.57 × 10(-11).     

Earthquake rupture dynamics frozen in exhumed ancient faults

Most of our knowledge about co-seismic rupture propagation is derived from inversion and interpretation of strong-ground-motion seismograms, laboratory experiments on rock and rock-analogue material, or inferred from theoretical and numerical elastodynamic models. However, additional information on dynamic rupture processes can be provided by direct observation of faults exhumed at the Earth's surface. Pseudotachylytes (solidified friction-induced melts) are the most certain fault-rock indicator of seismicity on ancient faults. Here we show how the asymmetry in distribution and the orientation of pseudotachylyte-filled secondary fractures around an exhumed fault can be used to reconstruct the earthquake rupture directivity, rupture velocity and fracture energy, by comparison with the theoretical dynamic stress field computed around propagating fractures. In particular, the studied natural network of pseudotachylytes is consistent with a dominant propagation direction during repeated seismic events and subsonic rupture propagation close to the Rayleigh wave velocity.     

关于高压子母叶片泵叶片倾角的探讨

针对子母叶片泵叶片倾角的选取影响叶片受力的问题,在考虑了子母叶片泵与普通低压叶片泵的结构及油腔供油原理的不同后,对叶片在吸油区受到的液压力,运动惯性力和接触反力进行建模.取一系列叶片倾角的值,仿真出叶片所受的接触反力变化曲线.经分析,比较得出:在双作用子母叶片泵中,当叶片倾角为零度时,叶片受力状况最佳.     

基于遗传算法的压缩机故障诊断

研究遗传算法在全封闭压缩机故障诊断中的实现,利用遗传算法的寻优特性,搜索出特征参数的最佳组合,利用行征参数的不同最佳组合分压缩机故障,将人工进化训练后生成的特征参数组合用于压缩机故障诊断试验,结果表明,有效提高了诊断精度,该方法对于压缩机故障诊断行之有效,且对机械系统故障诊断具有普遍意义。     

叶片泵定子内曲线轨迹辨识问题的研究

针对最小二乘法辨识叶片泵定子内曲线存在无法确定理论过渡曲线准确位置的缺点,提出了一种辨识曲线轨迹的新方法──残差分析法,解决了最小二乘法不能解决的问题,同时对高压叶片泵的大半径圆弧的包角提出了新的观点．     

赛罕乌拉自然保护区鸟类区系研究

１９９０－１９９９年,对赛罕乌拉自然保护区的鸟类进行了考察研究,共记录到鸟类１５０种,隶属于１７目４７科１０２属,其中６３种是夏修鸟,３８种是留鸟,１０种是冬候鸟,３９种是旅鸟。     

单板条层积材密度梯度的研究

通过不施胶压制单板条层积材(PSL)板坯,测定板坯各层的密度分布规律并对其进行统计分析。结果表明,板坯内各层的单板条压缩后密度呈正态分布。根据预测方程计算板坯密度梯度,并将密度梯度预测值与统计分布区间进行比较,结果表明,当热压压力低于5 MPa时,计算值能较好地与统计区间吻合,板坯密度梯度不大;当热压压力为5 MPa时,计算值与统计区间相差较大,经过分析修正,最终得出板坯密度梯度的计算模型。通过断面密度扫描试验,最终得出的计算模型能反映PSL板坯的密度梯度。
