Radioactive decay studies have found a kinds of elements can be α or β decay and the decay into another element, while the α-decay product of -α-rays became one of the deep structure of the material means of .1911, the Rutherford and others bombarded atoms with α-rays observed wide-angle deflection to determine the nuclear structure of atoms and nuclei was first proposed the term .1919 year, Rutherford and others have also found that with α-ray bombardment of nitrogen will release the nuclear protons, this is the first time Artificial realization of a nuclear reaction, after the bombardment of nuclei with the radiation caused by nuclear reaction method to become the primary means of research in nuclear.

放射性衰变研究发现了一种元素可以通过α衰变或β衰变而变成另外一种元素，而α衰变的产物——α射线又成了人们探讨物质深层结构的手段。1911年，卢瑟福等人用α射线轰击原子、观察到大角度偏折，从而确定了原子的有核结构，并首次提出原子核这一名词。1919年，卢瑟福等人又发现用α射线轰击氮核会放出质子，这是首次用人工实现的核反应，以后用射线轰击原子核来引起核反应的方法逐渐成为研究原子核的主要手段。

In the 1970s and 1980s, facing an ever-intensifying nuclear arms race between the United States and the Soviet Union, and tens of thousands of nuclear warheads, which, like dark clouds, hung over the heads of all people in the world and directly threatened China's safety, China had no other choice but to continue to carry out research and development of nuclear weapons technology and improve its nuclear weapons systems, mastering in succession the neutron bomb design technology and the nuclear weapon miniaturization technology.

70年代和80年代，面临着愈演愈烈的美国、苏联两国空前的核军备竞赛，数万枚核弹头的阴云笼罩在世界人民头上，也直接威胁到中国的安全，中国不得不继续研究发展核武器技术和改善自己的核武器系统，并先后掌握了中子弹设计技术和核武器小型化技术。

If that is indeed how things play out, the five countries that collectively proved unable or unwilling to stop Mr Kim's nuclear delinquency before his provocative nuclear test last October will have compounded failure with folly: encouraging nuclear wannabes to believe that the more rules they break, the bigger the eventual pay-off; and in the process eviscerating the Nuclear Non-Proliferation Treaty and setting off a dangerous series of nuclear chain reactions, from East Asia to the Middle East.

如果真的就这样结束的话，这五个国家将会犯下更多的愚蠢的错误（在去年十月份朝鲜进行核试射之前，他们并没有或者说并不愿阻止金正日的核计划）：这将会鼓励那些希望拥有核武器的国家相信规则破坏得越多，获利就越多，他们会继续使《核不扩散条约》的威信荡然无存，届时从东亚至中东会触发/引发一系列危险的核&多米诺&效应。

The results show that: 1 supplementation of protein to maturation media improves cumulus expansion in vitro compared to the protein-free control, but cumulus expansion is not necessarily related to oocyte nuclear maturation in pigs, and cumulus expansion is not the criterae for determination of nuclear maturation of pig oocytes, but only the exclusion of the first polar body; 2 exposure of pig COCs to hormone supplements for 23-24 hours improved cumulus expansion but had no significant effect on nuclear maturation compared to that for 46-48 hours; 3 under our research conditions, supplementation of different proteins into different maturation media has different effects on porcine oocyte nuclear maturation, but has no significant effect on subsequent embryonic development after IVF; 4 the nuclear maturation rates of pig oocytes matured in mTCM+pFF and mNCSU+pFF are superior than that in mNCSU+FCS; 5 different maturation media have no effect on pig oocyte cumulus expansion and subsequent embryonic development after IVF.

结果显示：(1)在成熟液中添加蛋白质可以加强卵丘细胞的扩散，但猪卵母细胞的核成熟与其周围的卵丘细胞扩展没有必然的联系，卵丘细胞扩散或成放射状不宜作为猪卵母细胞核成熟的标准，只有排出第一极体才能作为猪卵母细胞核成熟的标志；(2)在猪COCs的46-48小时成熟培养的后23-24小时阶段去除成熟液中的激素不但可以保证卵母细胞的核成熟率，而且可加强卵丘细胞的扩散；(3)在现有实验条件下，在mTCM和mNCSU中添加10％pFF与在mNCSU中添加10％FCS相比可获得较高的猪卵母细胞核成熟率；(4)在不同的成熟液中添加不同的蛋白质对猪卵母细胞核成熟率的影响效果不一样，但对体外受精后的早期胚胎发育影响不明显；(5)成熟液种类对猪卵母细胞的卵丘细胞扩散和体外受精后的早期胚胎发育无显著影响。

JNS sulfuric-acid-dew-point-resistance steel has been put into practical use in the construction of steel-covered chimneys of the following electric power-generating stations: Zou xian Power Plant （2 1000 MW）, Xiamen Songyu Power Plant （2 300 MW）, Fujian Nanpu Power Plant（2 300MW）,Shenzhen Power Plant （2 300MW）. Many experienced experts held discussions with designers at scene and reached a unanimous conclusion that "JNS sulfuric-acid-dew-point-corrosion -resistance steel " is more stable in terms of function, more convenient to weld and process and more safe to use than " past sulfuric-acid-dew-point-resistance steel". Reports from various laboratories demonstrate that "JNS sulfuric-acid-dew-point-corrosion -resistance steel " is more effective to resist acid corrosion than the former steel , and many exports predict after thorough study that this acid of steel have a life span longer than 30 years being used in de-sulfurized chimneys and it is much less expensive than titanium alloy clad plates and Peenguard, etc.

The following exciting results are revealed: 1 When considering the influence of some nonlinear elements such as hard-limit of exciters, the effects of some devices such as Power System Stabilizer and Static Var Compensator which can introduce positive damping in power system, the reasonability of system parameter values in simulation, the SNB surface and HB surface on the boundary of SSSR will turn close to each other and even coalesce together; 2 Under some conditions, coupling between slow exciters and shunt capacitors will bring negative damping in power system dynamics, which increases the possibility of oscillatory instability. So the power system with mass shunt compensators is easily subjected to the oscillatory instability. In recent years, chaotic phenomena of power system have been reported many times. Some simulation studies even found chaos existing inside the power system SSSR. In this dissertation, chaotic phenomena in power systems are thoroughly studied in order to make clear the relation of chaos and SSSR. The following results are derived: 1 Based on Li-Yorke Theorem and their definition on the chaos, the existence of chaos in power system is verified; 2 Three possible routes of causing chaos in power system are found and deeply investigated. They are route of cascading period doubling, route of directly initial energizing and route of torus bifurcation (or quasi-periodicity). The latter two routes are investigated for the first time in power system stability studies; 3 When the stability conditions of chaos are broken, it is found they can lead to voltage collapse, angle divergence, or voltage collapse with angle divergence simultaneously.

针对在电力系统小扰动稳定区域内可能存在混沌吸引域的有关报道，本文深入研究了电力系统混沌现象的出现途径和与系统失稳模式之间的关系：1利用Li-Yorke定理和Li-Yorke的混沌定义，从理论上证明了电力系统混沌现象的存在性；2发现了电力系统中导致混沌出现的三种可能途径：倍周期分岔导致混沌、初始能量直接激发混沌和经由环面分岔导致混沌，并对后两种新发现的途径进行了较为细致的研究；3发现了混沌极限环破裂导致电压崩溃、角度失稳以及电压崩溃和角度失稳同时出现的现象，其中混沌极限环破裂导致系统角度失稳和电压崩溃及角度失稳同时出现的现象均属首次报道；4证明由微分-代数方程描述的系统模型，其小扰动稳定域的边界只包含HB、SNB和SIB三种分岔界面，在SSSR的内部和边界上，均不可能存在会导致混沌的点，从而将混沌现象排除在小扰动稳定域的研究之外，简化了后者的研究工作。
