Pine wilt disease (PWD), which is caused by pine wood nematodes (PWN), is one of the most serious forest diseases worldwide. To clarify the mechanism of resistance to PWD, we compared metabolites from resistant and susceptible Japanese black pine (Pinus thunbergii) families after inoculation with PWN. After 2 weeks to 1 month post inoculation, the number of PWN dramatically increased in susceptible plants, but not in resistant plants. At this PWN-proliferation phase, ethyl acetate soluble fractions extracted from PWN-inoculated plants were analyzed by gas chromatogramphy-mass spectrometry (GC-MS). Although most compounds were qualitatively and quantitatively similar between resistant and susceptible plants, resistant plants accumulated 2.0-fold more linoleic acid (LA) than susceptible plants. On the other hand, benzoic acid (BA) was barely detected in resistant plants, but it accumulated in susceptible plants as the number of PWN increased. Susceptible plants contained greater levels of the nematicidal compounds pinosylvin and pinosylvin monomethyl ether, compared with resistant plants. These results suggested that LA is involved in the resistance reaction against PWN-proliferation, and that BA could be a good biomarker for PWD.

针对海因法合成蛋氨酸工艺,利用间歇动态法、以蛋氨酸钾为原料研究了CO_(2)酸化条件下蛋氨酸的反应结晶过程,建立结晶动力学模型。通过矩量变化法求解粒数衡算方程,利用最小二乘法对数据多元线性回归得到结晶动力学参数。结果表明:晶体生长类型为粒度无关生长,晶体生长活化能为21.01 kJ·mol^(-1),成核与生长速率方程中过饱和度的指数分别为0.62和1.52,晶体聚结对结晶过程的影响不可忽略。气体表观速率、搅拌速率对晶体成核与聚结均有明显影响。高过饱和度与高搅拌转速不利于晶体平均粒径的增加。

通过对LED封装结构热模拟分析表明,模拟固晶胶粘贴部分失效的情况下,采用热导率为0.1W/m.K的普通硅胶封装成的LED芯片最高温度为220.27°C,采用导热填料高热导率硅胶灌封的LED芯片最高温度可降低到122.71°C,大幅降低了芯片的温度。纳米ZnO导热填料高热导率硅胶,其填料颗粒的直径小于25 nm,透光率高,可适用于LED封装。高温加速老化结果表明,采用导热硅胶灌封的LED样品具有很好的热稳定性,LED高温老化2 000 h后,光通维持率保持在90%以上,避免了由于灌封材料和荧光粉老化产生的黑褐色覆盖层,提高热稳定性和器件使用寿命。

人是天然的政治动物,也是天生的仪式动物。大卫·科泽的《仪式、政治与权力》一书聚焦于"政治仪式如何在政治生活中运作",在进行大量史料收集的基础上,对仪式在人类生活中的作用和政治生活的本质进行了阐释,为理解人类的"政治仪式"特性作出了巨大贡献。事实上,警察荣誉仪式作为一项重要的政治仪式,同样可以从《仪式、政治与权力》中获得研究警察荣誉仪式的建构过程的重要启示,这也是警察荣誉仪式研究视角的创新之处。基于此,笔者在详细分析《仪式、政治与权力》一书的写作旨义、主要内容、研究特色的基础上,进一步分析其对于警察荣誉仪式的建构过程的启示,以期为后续研究提供参考。
