Referenced to the CSR's trilogic PWM signal generation, an approach to achieve lowstress natural commutation of switching devices by reshuffling the vector composition sequence, resulting reduced switching loss. With the background of and well instanced by the Xinjiang Autonomous Region's Key SciTech Project"Solar Photovoltaic grid-connected inverter", the dissertation work implemented the new approach of a grid-connected PV inverter that was of single-phase VSR topology and with MPPT .

在研究了两类电网不平衡时的VSR控制策略基础上，提出了一种新型的基于无阻尼振荡控制器的VSR不平衡控制策略，在简化控制结构的同时，有效地改善了电网不平衡时的VSR控制性能；通过二、三值逻辑开关函数间的转换，系统地描述了三相CSR三值逻辑PWM信号发生中的状态切换；结合三相CSR三值逻辑PWM信号发生规律，提出了通过调整矢量合成顺序而使功率管获得自然换相的低电压应力SVPWM控制，从而有效地降低了功率管的开关损耗。

Although he kept trowing up his arms in despair, but he accepted that 5 pounds I gave him readily.

虽然他绝望地不停地向空中甩着胳膊，然而还是很欣然地接过了我给他的那5英镑。

Because no matter how master an artist was, he dared not draw an emperor uglily---- a grog blossom might be beautified as high and straight one, small ears might be overleaped by the artists on purpose, but we shouldn't blame them much as it is more important to linger on in a steadily worsening condition than to devote for art.

无论多么高超的画家都不敢轻易地把把皇帝画丑了，酒糟鼻也许会幻化成高挺的鼻梁，小耳朵也许让画家故意地省略。这怪不得画家，苟延残喘地活着比为艺术献身要来得实在。

And the lazy person is so lazy, so unalert, so unconscious, that he cannot see.

而懒人是如此地懒惰，如此地不警觉，如此地无意识，以至于他不能看到。

Based on the regional tectonic evolution, combined with the high precision isotopic ages from this paper and other geologists, we have some new acquaintances as follows: 1 There has no Caledonian granite belt distributed in north margin of North China Craton. So, the traditional evolving model of North China Carton, which formed on this idea and the acquaintance about the collision of North China plate and Siberian plate, must be incorrect; 2 The age date show that the earliest magmatic activity began since late-Palaeozoic Permian, which is inconsistent with the previous idea that there were Caledonian and Hercynian active continental margin in the north of North China Craton and in the south Xingkai Massif. 3 the crust and lithosphere were thickened by the subduction and collision of Siberia plate and North China plate during Late Paleozoic. The magma is formed when the crust is heated and melts caused by thickened lithosphere delamination and caused the Asthenosphere upwelling. But only a little basaltic magma erupted, most magma underplate under the bottom of the crust. Thermal energy derived from basaltic magma underplating made the middle and lower crust melt partially and the late Permian-early Triassic granites is formed in large scale.

根据区域构造演化分析，并结合本文及他人高精度同位素年龄，我们对延边花岗岩形成的大地构造环境有了新的认识：1在华北地台北缘并不存在所谓的加里东花岗岩带，因此，建立在此之上的传统的华北地台北缘演化模式及有关西伯利亚板块与华北板块的碰撞拼合的认识也必然是不正确的；2华北地台北缘和兴凯地块南缘不存在加里东期和海西期花岗岩带，表明两地块边缘最早的花岗质岩浆活动始于晚古生代的二叠纪，即不存在传统观点所认为的加里东期或海西期活动陆缘；3晚古生代由于西伯利亚板块与华北板块的俯冲碰撞，致使地壳和岩石圈增厚，导致加厚岩石圈发生拆沉作用，使得软流圈上涌，加热地壳使之熔融形成岩浆，但玄武质岩浆少量喷出地表，大部分底侵于地壳底部，形成下地壳高密度的玄武质底侵层，玄武质岩浆底侵的热能引起中下地壳广泛部分熔融，形成大面积分布的晚二叠世—早三叠世花岗岩。

In this dissertation,Co-Cr2O3 and Fe-Cr2O3 granular films with superiorproperties have been successfully fabricated by RF co-sputtering technique underroom and 77K substrate temperatures for the first time.The microstructure,electrical transport and magnetic properties as well as their relation to TMR effectare systematically investigated by various techniques such as X-Ray diffraction,transmission electron microscopy,electrical diffraction,X-Rayphotoelectron spectroscopyand VSM,etc.,the change of electrical transportand magnetic properties in these films with their microstructure is also shown.Someinteresting and valuable results have been obtained after the theoretical fitting ofexperimental data with the existed theory.The temperature dependence of TMReffects in these films and the way to get larger TMR effect is also studied.Our mainprincipal results obtained are as follows:(1)Microstructure and Magnetism

Thus by studying the unconsciousness of culture we can further understand the undividable dialectical relations between culture and man and the important recessive factors in the structure of the main cultural spirit and cognition as better to discipline man's behaviors and understand man himself.

通过研究文化无意识，可以使我们更好地理解文化与人之间密不可分的辩证关系，以及文化主体的精神和认识结构中重要的隐性因素，从而更好地规约人的行为，更好地理解人本身。
