Experimental results prove that the shunt APF system with cascade multilevel converter based on CPS-SPWM can achieve excellent compensation effect even under much lower switching frequency. We can easily get to the conclusion: this method has a perfect prospect in industry application.

通过一系列实验验证了将基于CPS-SPWM技术的级联型多电平变流器应用于APF上能较好地实现对非线性负载引起的谐波及无功污染的补偿，有良好的工业应用前景。

Gangliosides antagonized the apoptosis induced by corticosteron, and the underlying mechanism is related to activiation of neuronal calcium signal cascade, promoting neurotransmitter release. Gangliosides also have an ability to promote the neuronal filopodia formation and may have a antidepressive-like neuroprotecive effect. 2. Theory study: We explained the clinical symptoms showed in the syndromes of deficiency of kidney-Yang and deficiency of kidney-Yin with modern scientific technical terms. Moreover, we supposed the location of kidney of traditional Chinese medicine may be in the hippocampus but not in the hypothalamus, which is also the centre of learning and memory.

鹿茸有效成分能够拮抗皮质酮诱导的神经细胞凋亡，其机制与影响钙信号途径、促进神经递质释放有关，鹿茸有效成分还能促进神经细胞丝状伪足生长，并且可能具有抗抑郁药样的神经保护作用。2、理论研究：用现代科学语言对肾阳虚证和肾阴虚证临床症状的病理生理机制进行合理的解释，提出中医肾脑相关理论实质假说，推测补肾中药的调控点应当在下丘脑—垂体—肾上腺轴的高级中枢海马，而非下丘脑。

It will take time to answer the big questions: why so many changes are happening so fast; whether abrupt, extreme events like cyclones and ice melts will lead to a cascade of other events; how cause and effect interact in complex ecosystems where small changes may be synergistically amplified.

解决一些大的问题需要时日：为什么很多这样的变化发生得如此快？是否突发的、极端的，象飓风和冰化这样事件，将导致一连串的其它事件？在复杂的生态系统中因果之间怎样相互影响，而且小的变化在相互作用中会被放大吗？

It can account for many phenomena which expected utility theory has so far failed to explain, such as Allais paradox, Ellsberg paradox, preference reversal, certainty effect, reflection effect, isolation effect, common ratio effect.

后悔理论能够很好地说明期望效用理论所不能解释的Allais悖论、Ellsberg悖论、偏好反转现象、确定性效应、反射效应、分离效应、共同比率效应等异象，而且能够应用于决策理论和资产定价等金融领域。

In this thesis,based on the DFT+NEGF first-principles method,we construct a lead-molecule-lead sandwich system with single benzene-based molecule to investigate the relationship between the structure and properties of the molecular devices and the factors that influence properties of the molecular devices.Our computational investigations on these molecular devices are primarily concentrated on the effect of contact geometry between molecules and electrodes,the effect of side groups,the effect of different torsion angle between two phenyl rings and the effect of external electric field.This thesis consists of five chapters:In Chapter one,we mainly introduce the research background and development of the molecular electronics,including the experimental fabrication of molecular electronic components and theoretical simulation methods.Afterwards we discuss the questions that need to be solved in this area.Finally,the main contents of this thesis are listed.In Chapter two,we introduce the theoretical methods used in this thesis, including the main first-principles calculation methods,i.e.,the Density-Functionmethod and nonequilibrium Green\'s function.

Institute of Plant Protection, Anhui Academy of Agricultural Science, Hefei 230031, China Abstract: The control effect of propiconazole microcapsule to postharvest anthracnose of apple and their application techniques at 25℃ and 10℃ in storage were studied. The results showed that the difference between the control effect with spraying and soaking were significant, the control effect of fast release for propiconazole microcapsule was better than that of slow release. The control effect of fast release for propiconazole microcapsule was 100% at 25℃ in storage, and was 86.8% 10℃ in storage.
