流行词“吃货”的多角度考察

"吃货"最早出现在清代小说中,指光吃不干活的人,带有贬义色彩。近年来,"吃货"一词被广大美食爱好者广泛传播,用于自称和互称。"吃货"一词的词义已发生明显变化,指"喜欢吃各类美食的人,有品位的美食爱好者";词义附带的感情色彩逐渐趋于中性甚至褒义。而导致这些变化的原因主要是人们对"吃"观念的改变,网络语言环境的高度自由化以及使用网络语言的从众心理。

基于结构层贡献率的沥青路面抗车辙措施

采用环道试验及德国汉堡车辙试验方法,研究在中面层使用改性沥青对路面结构和组合结构抗车辙性能的影响,包括对结构层贡献率和对沥青层剪切流动变形的影响;探讨在中面层添加纤维对路面结构抗车辙能力的影响.研究结果表明:中面层使用改性沥青,能提高路面结构的整体抗车辙性能;使剪切流动变形由95.2%下降至84.4%;中面层变形贡献率达到60%以上,应该重视提高中面层的抗车辙能力;对于中面层采用普通沥青的结构,在中面层添加纤维可明显减少整个结构车辙深度,但对于中面层已采用改性沥青的结构,添加纤维减少车辙的效果不明显.

Effect of KNbO3 content on the crystal structure and electrical properties of (1 − x)PbZr0.54Ti0.46O3-xKNbO3 piezoelectric ceramics

(1 ? x)PbZr_0.54Ti_0.46O₃-xKNbO₃ (0 ≤ x ≤ 25mol%) (abbreviated as PZT-xKN) piezoelectric ceramics were successfully fabricated by a traditional sintering technique at 1225°C for 30 min. The influence of KNbO₃ content on the crystal structure and electrical properties of the PZT-xKN piezoelectric ceramics was studied. Samples with 0 ≤ x ≤ 0.20 show a pure perovskite structure, indicating that all KNbO₃ diffused into the crystal lattice of PZT to form a single solid solution in this compositional range. A second Pb₃Nb₄O₁₃ phase is observed in the PZT-0.25KN sample, showing that the maximum solid solubility of KNbO₃ in PZT matrix ceramic is less than 25mol%. Compared with pure PZT piezoelectric ceramics, samples containing KNbO₃ have smaller crystal grains. PZT-0.15KN exhibits excellent piezoelectric properties with d ₃₃ = 209 pC/N.

Proteome changes in the plasma of Papilio xuthus (Lepidoptera: Papilionidae): effect of parasitization by the endoparasitic wasp Pteromalus puparum (Hymenoptera: Pteromalidae)

Although the biochemical dissection of parasitoid-host interactions is becoming well characterized, the molecular knowledge concerning them is minimal. In order to understand the molecular bases of the host immune response to parasitoid attack, we explored the response of Papilio xuthus parasitized by the endoparasitic wasp Pteromalus puparum using proteomic approach. By examining the differential expression of plasma proteins in the parasitized and unparasitized host pupae by two-dimensional (2D) electrophoresis, 16 proteins were found to vary in relation to parasitization compared with unparasitized control samples. All of them were submitted to identification by mass spectrometry coupled with a database search. The modulated proteins were found to fall into the following functional groups: humoral or cellular immunity, detoxification, energy metabolism, and others. This study contributes insights into the molecular mechanism of the relationships between parasitoids and their host insects.
