In 5 century B.C., ancient Grecian historian Thucydides had ever described this case . In the early 1950's, American and Britain scholars John Herz and Herbert Butterfield formally put forward this concept. Because of the cold war between America and Soviet, at the same time, realism and neorealism lying in the leading position of international relations theory academia, security dilemma plays eminent role in interstate relations after World War Two.

早在公元前5世纪古希腊历史学家修昔底德就对这一情形有所描述。20世纪50年代初，美英学者赫兹和巴特菲尔德正式提出这一概念，由于美苏两个超级大国爆发冷战、对峙乃至军备竞赛，以及现实主义和新现实主义在国际关系理论界居主导地位，"安全困境"在战后国际关系中发挥着显赫的作用。

Through immunocytochemistry study, we found that the α3 and/or α5 subunits of nicotinic acetylcholine receptor are predominantly expressed in the oxytocinergic neurons. Our finding is quite different from the conclusion of the British scholar Dr. Mason's work in 1980s. We also found in this study that, the α3 and/or α5 subunits of N-AChR can also be expressed on the axons of oxytocinergic neurons, and these immunoreactive axons could be seen projecting to the median eminence and further to the posterior end of neurohypophysis. In the hypothalamus of the 7-day postnatal pup rats, the expression patterns of α3 and/or α5 subunits of N-AChR are similar to that in adult rats.

我们用免疫组化的方法发现，α3和/或α5型烟碱型乙酰胆碱受体(Nicotinic acetylcholine receptor，N-AChR)亚单位在大鼠下丘脑OT能神经元中呈优势性的表达，这与上世纪八十年代英国学者Mason类似工作的结论不一致；而且我们还发现α3和/或α5型N-AChR亚单位还表达在OT能神经元的轴突，此阳性免疫反应的轴突一直延续到正中隆起和神经垂体的末端；在新生7天大鼠的下丘脑，α3和/或α5型N-AChR亚单位的分布类似成年鼠。

It is now many years that men have resorted to the forest for fuel and the materials of the arts: the New Englander and the New Hollander, the Parisian and the Celt, the farmer and Robin Hood, Goody Blake and Harry Gill; in most parts of the world the prince and the peasant,the scholar and the savage, equally require still a few sticks from the forest to warm them and cook their food.

多少年代了啊，人类总是到森林中去找燃料和艺术的材料；新英格兰人，新荷兰人，巴黎人，克尔特人，农夫，罗宾汉，戈底。勃莱克和哈莱。吉尔；世界各地的王子和乡下人，学者和野蛮人，都要到森林里去拿一些木头出来，生火取暖煮饭。

In the late 1980s, the scholar Paul Kennedy predicted the imminent collapse of American power due to "imperial overstretch."

在八十年代末，学者肯尼迪预言美国强权由于"权威过度扩张"面临崩溃。

The discovery of annual density bands of mass coral skeleton had a profound effect on coral paleoclimatology, and many patterns of density bands have been revealed throughout the global tropic ocean since then. At the first stage, people tended to explore the control factors of density changes from the environment where the coral grows, but they did not succeed. Since later part of 1980s, some researchers have focused on the skeletal architecture and integrated the signals of both environment condition and skeleton density bands to reveal the mechanism of skeleton density changes, and finally a model of skeleton growth was developed which can explain the almost existed patterns of skeleton density changes.

块状珊瑚骨骼密度条带年周期的发现对后来的珊瑚古气候研究产生了深远的影响，随后又发现世界各热带海域的珊瑚存在多种多样的骨骼密度变化模式，起先常从珊瑚的生长环境中寻找骨骼密度变化的控制因素，但是没有成功，从80年代后期，部分学者试图从珊瑚骨骼构架本身出发、综合考虑环境因素和骨骼密度条带之间的关系来探求骨骼密度变化的机理，并提出了一个可以解释大多数块状珊瑚骨骼密度条带变化模式的骨骼生长模型。

Many Russia scholars believe ochre petroglyph were at the same age as slab-stone tombs'.

俄罗斯学者普遍认为赭石岩画与石板墓的年代相当。

From 20 centuries 70 time rise, a lot of information experts, philologist and orgnaization of a few an academic authority are opposite abroad the summary has had thorough and careful research, china also has the person such as Ren Shengli to had had a description to the macrostructure of the summary and microcosmic language.

从20世纪70年代起，国外许多信息专家、语言学者和一些学术权威机构都对摘要进行过深入细致的探究，中国也有任胜利等人对摘要的宏观结构和微观语言进行过描述。

Since 1980s,not few scholars in philologist circles had made discussions on the grammaticalized process of"著"from differcnt angles.

自80年代以来，语言学界已有不少学者从不同角度讨论了"著"的语法化过程。

The uncertainty attracts much attention of the system theory experts, the cybernetics experts, the information theory experts, the physical scientist and the mathematician in the early 1990s.

非确定是本世纪九十年代初期系统论、控制论、信息论、物理学和数学专家学者十分关注的领域。

e-PTFE was implanted into the pitting area after subcuntaneous disjunction. Results: 15 cases were followed for about 3 and 6 momths after implant of e-PTFE, including cases with saddle nose, pitting deformity of orbit, congenital lip cleft with depressed soft tissue around pyriform opening, parbial defect of helix. In these cases, satisfaction rate is evaluated as high as 97.9%, unexpected tissue response was not shown in this clinical trail.Conclusion: Depended on this clinical trail, we believe local e-PTFE manufactured by Shanghai Suo-kang Medical Implants Co., Ltd.

由于e-PTFE的组织相容性好，在80年代初期一些发达国家已经应用于整形美容外科[1]，尤其应用于隆鼻术、面部凹陷畸形的整复、唇线增高、唇加厚、鼻唇沟过深的整形美容术、耳廓缺损等手术中，学者们认为e-PTFE排斥反应的发生率低，弹性和硬度与软组织相似，周围组织细胞能够长期进入移植物内，不形成纤维囊，在整形美容外科领域有重要的应用价值。
