Through microstructure observation and X-ray diffraction analysis, the equilibrium phase constituents of Al-Zn alloy that contains 2 at. pct Cu at room temperature have been determined as Al-based solid solution (α), Zn-based solid solution and AI4Cu3Zn phase (T'-phase), which are different from a phase, Zn phase and CuZn4 phase originally believed. It is determined that the products of discontinuous precipitation transformation below 277℃ are not the equilibrium phase constituents, but the metastable phases made up of a phase, Zn phase and CuZn4 phase. The phase constituents after discontinuous precipitation of AIZn-2Cu alloy would transform to the ones in equilibrium status: Al-based solid solution (α) in fcc structure, Zn-based solid solution in hcp structure and AI4Cu3Zn phase (T'-phase) ultimately through plastic deformation at room temperature and re-heating treatment below 277℃.

To evaluate the phacoemulsification and intraocular lens implantation in patients with sensory exotropia subsequent to senile cataract. The authors prospectively studied the role of phacoemulsification and intraocular lens implantation on 25 patients by observing visual acuity, ocular alignment, binocular vision and diplopia pre-, 1 month post- and 3 months post-operation. The patients underwent follow-up for three months. Postoperatively, one patient had a corrected visual acuity of 20/50, and 24 patients had 20/40 or better. The ocular alignment, binocular vision and diplopia were resolved spontaneously. Phacoemulsification and intraocular lens implantation performed together is effective on sensory exotropia subsequent to senile cataract.

Translation involves not only formal transformation of two languages concerned, but also conversion of thought patterns. The oriental thought pattern is considered ＂concrete＂, ＂man-centered＂, and ＂ordinal＂; while the western one is believed to be ＂abstract＂, ＂object-centered＂, and ＂conversed＂. These are the decisive factors for the existence of the differences in language expressing. It is of great importance to study these differences and make some adjustments in terms of syntactic structure, semantic focus, and time order so as to achieve a natural rending.

Background： Standard automated perimetry does not sufficiently detect early open-angle glaucoma （OAG） in the clinic. New visual function tests for early glaucoma damage are therefore needed. The present study evaluated whether an isolated-check visual evoked potential （icVEP） could be used to detect visual function abnormalities in early-stage OAG and to explore potential related factors. Methods： This was a cross-sectional study. Thirty-seven OAG patients with early-stage visual field loss （mean deviation ≥ -6.00 dB） detected by the Humphrey Field Analyzer （30-2 SITA program） and 26 controls were included in this study. Optical coherence tomography （OCT） was used to detect retinal nerve fiber layer （RNFL） defects. The icVEP preferentially evaluates the magnocellular-ON pathway. VEPs were recorded and signal-to-noise ratios （SNRs） were derived based on multivariate analysis. Eyes that yielded an SNR ≤1 were considered abnormal. Receiver operating characteristic （ROC） curve analysis was used to estimate the accuracy of group classification. Correlations between SNRs and related factors were analyzed. Results： Based on an SNR criterion of 1, the icVEP had a sensitivity of 62.2% and a specificity of 92.3% for diagnosing early-stage OAG with 74.6% classification accuracy. The ROC curve analysis, however, suggested that an SNR criterion of 0.93 would produce the highest classification accuracy （77.3%）. Both RNFL thinning in the temporal superior quadrant on OCT and number of abnormal test points in the central 11° visual field （pattern deviation, P 〈 0.5%） significantly correlated with the SNR （P 〈 0.05）. Conclusions： The icVEP detected visual function abnormalities in approximately 3/5 of eyes with early-stage OAG with greater than 90% specificity. SNR correlated with both a decrease in RNFL thickness and severity of central visual field loss.

Studies prove that there are strong relationships between vocabulary development and reading comprehension. In English, there is a relatively close relationship between the vocabulary size and English language proficiency. Reading represents the primary way that ESL learners in China can learn on their own beyond the classroom. But vocabulary size in reading comprehension strongly limits the sorts of texts that they can read with ease. First, the problems Chinese EFL learners and teachers confront in comprehensive reading are revealed. And then some feasible ways of helping learners build word size in real teaching practice are demonstrated.

稀土掺杂是提高光电功能材料性能的重要途径.把稀土掺杂铁电材料与稀土发光相结合,还可拓展出铁电材料的新性能,比如,选择合适的稀土元素掺入钛酸铋铁电材料,可使之在保持较好的铁电性能的同时,又显示良好的发光性能.近年来,这类在氧化物铁电材料中由于稀土离子掺杂产生光致发光特性的研究引起了人们的关注,有望研制集成发光铁电器件.本文简要介绍了稀土发光铁电材料的研究状况,重点介绍我们在稀土发光铁电薄膜方向的研究进展.我们的研究表明,稀土掺杂钛酸铋铁电薄膜同时具有较好的发光特性和铁电特性,这与其独特的成分构成和层状钙钛矿结构密切相关;Eu3+离子荧光结构探针可以为进一步研究Eu3+掺杂铁电薄膜材料的结构与性能关系提供新思路;在某些铁电薄膜(如Pr离子掺杂的x(K1/2Bi1/2)TiO3-(1-x)(Na1/2Bi1/2)TiO3薄膜等)中掺入稀土离子后,稀土离子的发光可用于检测铁电薄膜中是否存在准同型相界;将ZnO纳米材料和金、银纳米颗粒与掺铕钛酸铋薄膜复合,可显著增强稀土发光.
