Acetate groups charge ZnO nanocrystals negatively and passivate the surfaces,reducing the surface defects and visible emission centers. Resultantly, the increase of acetategroups lead to the quench of visible emission and improvement of photoluminescenceproperties. At appropriate concentrations, the hydroxide groups mainly passivate the surfaceand improve the photoluminescence properties.
研究发现,氢氧化锂/醋酸锌的比值对胶体氧化锌量子点的发光性质有重要影响;醋酸根基团通过使氧化锌粒子带负电荷并钝化其表面,使得氧化锌纳米点的表面缺陷和可见发射中心大大减少,因此醋酸根浓度的增大导致了可见发光的淬灭和发光性质的增强;氢氧根基团在中等浓度时主要起钝化氧化锌表面的作用,使产物的发光性质得到改善。

The three novels catch hold of the kernel of contradictory political forces, and reveal the conflicting relationship between the factors of the desires for power in English cultural tradition, and refract the paradoxes formed from the unsolvable problems in the political modernization: the modernization in England upgraded prolificacy with an unprecedented speed, offering opportunities of emancipation of personal desires, the appealing to personal power in politics pressed for a breakthrough in the traditional political setups, leading reform to modernization, which emancipated political forces, aggrandized political rights, and satisfied some people\'s desire for power in a certain extent.
这三部小说抓住了现代化进程中各种政治力量的相互矛盾这个核心,揭示了英国传统文化中欲望力量诸因素相互冲突的关系,折射了政治现代化难以解决的矛盾所形成的悖论:一方面,英国现代化进程前所未有地提升了生产力,使人的个性解放成为可能,个人权利的诉求迫切要求冲破传统的政治格局,使政治通过改革走向现代化。

To improve the stability of Arcjet discharge plasma in low current and high voltage mode, research on the demand of output characteristics of Arcjet Power Conditioning Unit was conducted. In this paper, based on PWM invertors and current mode control, using MOSFET as the main power device, an Arcjet Power Conditioning Unit was developed. Through adding a closed loop feedback circuit of output voltage, it can make the output characteristics of PCU be positive resistance to ensure the stability of Arcjet discharge plasma. The experiment indicates that this PCU can make Arcjet engine work at high voltage mode (100 V, 10 A) and ensure the stability of arcjet discharge plasma. Finally, it provides the experimental data of Arcjet when working.
