汉语同语的功能特点与英译策略

以北大语料库(CCL)为例,分析论述汉语同语的功能特点.除了和英语同语一样可以表示强调以外,它们还具有转折、让步和赞誉的功能.对汉语同语进行英译时,应通过“理解-传递-体现”三个阶段实现功能对等.对表强调功能的单举式同语,可以保留其语言形式;对具有转折、让步和赞誉功能以及表强调功能的对举式同语,则应弃形式、保功能.     

A MKL based on-line prediction for gasholder level in steel industry

The real-time prediction for gasholder level is significant for gas scheduling in steel enterprises. In this study, we extended the least squares support vector regression (LSSVR) to multiple kernel learning (MKL) based on reduced gradient method. The MKL based LSSVR, using the optimal linear combination of kernels, improves the generalization of the model and reduces the training time. The experiments using the classical non-flat function and the practical problem shows that the proposed method achieves well performance and high computational efficiency. And, an application system based on the approach is developed and applied to the practice of Shanghai Baosteel Co. Ltd.

Preparation of BaTiO3-Based Nonreducible X7R Dielectric Materials Via Nanometer Powders Doping

Nonreducible X7R dielectric materials, which can be cofired with Ni electrode, were obtained by doping nanometer additives to BaTiO₃ powders synthesized by employing a sol-gel method. The crystallization process, structure and constituent of nanometer additives, as well as morphologies were studied via differential thermal and thermogravimetric analyses (DTA/TG), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The effects of the calcining temperature of dopants on the dielectric properties were also discussed. The experiment results proved that higher-performance X7R dielectric materials could be obtained via nanometer doping compared with conventional doping. At room temperature, dielectric constant is more than 3000; dielectric loss lower than 1.0% and insulation resistance more than 10¹¹Ω ⋅cm.     

Abnormal growth of austenite grain of low-carbon steel

Niobium is an important alloying element for the steel. To know further the effect of Nb in the steel, the contrast experiments on the austenite grain growth of the 0.015%Nb and free Nb steels were carried out using Gleeble 1500 thermomechanical simulator. The experimental results indicate that the austenite grain of 0.015%Nb steel is finer than that of Nb free steel at 1150–1230 °C. And when the heating temperature arrives the critical temperature 1240 °C, the austenite grain of Nb steel suddenly grows up, while the austenite grain of Nb free steel changes little. Finally, the austenite grain of Nb steel is obviously coarser than that of Nb free steel. By transmission electron microscopy (TEM) using a carbon extraction replica technique, the precipitates of Nb(C,N) were not observed in the 0.015%Nb steel. It is concluded that the grain-boundary internal adsorption of Nb atoms leads to the result.

New Application of Stainless Steel

Several rigid substrates such as stainless steel, titanium alloy, aluminum alloy, nickel foil, silicon, and sodium lime glass have been employed for manufacturing high quality TiO2 films by metal organic chemical vapor deposition （MOCVD）. The as-deposited TiO2 films have been characterized with SEM/EDX and XRD. The photocatalytic properties were investigated by decomposition of aqueous orange Ⅱ. UV VIS photospectrometer was employed to check the absorption characteristics and photocatalytic degradation activity. The results show that films synthesized on metal substrates display higher photoactivities than that on absolute substrates such as silicon and glass. It is found that solar light is an alternative to UV-light used for illumination during photodegradation of orange Ⅱ. TiO2 film on stainless steel substrate was regarded as the best one for photocatalysis.
