During the course of the well-known "new mathematics" campaign, the status of Euclidean geometry was completely overthrown in I960" s. After deeply thought of "new mathematics", the standpoint that geometry curriculum should reflect the content and method of modern geometry and be in touch with the student" s real life was agreed on. Other countries have tried some significant attempts. We can find from some geometry textbooks that the methods of transform and vector have appeared as a normal part. Simultaneous, not only the new developments of geometry such as Topology have been referred , but also the connection between geometry and practice has been strengthened.In China, geometry curriculum is also in the during of innovation.

而学校几何课程在二千年的时间里一直没有多大的变化，直到二十世纪初"克莱因—培利运动"的第一次冲击，到60年代"新数学"运动的全盘改革，以及之后的深入反思，中学几何课程要反映现代几何学的内容和方法以及紧密联系于实践的观点已经受到普遍的重视，国外的几何课程已经在这方面做了不少有意义的尝试，从国外的一些几何教材中可以发现：变换、向量等工具已经作为正式的内容进入几何教学，拓扑学等几何的新发展也开始在教材中有所体现；几何课程与实践之间的联系更是在很大程度上得以加强。

Chapter four studies the chaotic responses in a system consisting of simple pendulum and harmonic oscillator under bounded noise excitation. Firstly, the Melnikov function of the two-degree-of-freedom system under Hamiltonian perturbation is derived. The essential condition of the autonomous system for the probable onset of chaos is obtained, the Poincare maps of the system under small Hamiltonian perturbation and the effect of increasing perturbation on the Poincare maps are studies. Then for the non-autonomous system under damping and harmonic or bounded noise excitation, the largest Lyapunov exponent and Poincare maps are calculated. From the analysis of the largest Lyapunov exponent, the critical criterion for the onset of chaos, and the conclusion that the threshold of bounded noise amplitude for the onset of chaos in the system increases as the intensity parameter of Wiener process increases are obtained. The result from the analysis of Poincare maps is in agreement with that obtained from the Largest Lyapunov exponent. The effect of varying damping coefficient and intensity parameter of Wiener process is also analyzed.

第四章研究了有界噪声激励下的两自由度单摆—谐振子系统的混沌运动，首先推导了该两自由度系统仅在Hamilton扰动下的Melnikov函数，得到该自治系统可能产生混沌的必要条件；研究了该系统在小的Hamilton扰动和增大摄动情形下的Poincare截面；然后对有阻尼、谐和或有界噪声激励下的非自治系统数值计算了其最大Lyapunov指数和Poincare截面；从Lyapunov指数分析得到了这个两自由度系统产生混沌运动的临界条件及产生混沌的临界激励幅值随Wiener过程强度参数值的增大而增大的结论，Poincare截面分析的结果亦符合Lyapunov指数分析的结论；研究了Wiener过程强度参数、阻尼系数变化对Poincare截面的影响。

一个牛市运动的最后阶段是一场接近顶部的加速赛跑。在这一阶段，市场总是让你相信你低估了潜在的牛市。随著盈利膨胀到让你相信你的账户可以对付任何挫折，继续堆砌你的头寸金字塔的诱惑强大。在这关键的时候，要紧的是从你的金字塔上拿走你的盈利，把你的头寸减少到基本水平。随后，当这一运动变得显然结束了时，将这基本头寸也平仓。

When American Pop art met the Chinese modernism in that very context, a certain mystery was produced: Pop art was readily understood as a Dadaist destructive art, while its cultural deconstructive property seemed to be ignored. By the early 1990s, due to the political reason, China had undergone its rapid social and cultural transition from Enlightenment era to consumerist era, while artists, who were still in despair because of the failure of cultural Enlightenment movement, found themselves confronted with a completely new economic market and their ideas mingled with those of modernist Enlightenment and post-modern deconstruction.

它以风格上挪用、平面化、去意义、去价值这类语言策略解构和消除现代主义的启蒙神话，成为与后现代主义哲学同构的文化思潮。80年代初沃霍尔访华，尤其是1985年劳申伯在北京和拉萨举办个展开始了美国波普主义在中国的传播，而这时正值中国85现代主义运动的高潮，启蒙和反叛是这一运动的主题，正是这种语境使这种传播产生了十分吊诡的意义落差：波普主义很轻易地被理解为一种达达式的破坏性艺术，而它的文化解构主义色彩反倒不易被体会。90年代初中国社会由于政治的原因急促地完成了由启蒙文化向消费文化的转型，艺术家们还沉迷在文化启蒙运动失败的悲壮气氛中却突然发现自己已深陷在一个一完全陌生的经济世界中，理想的失落和批判身份的丧失使他们的思想开始混杂于现代主义的启蒙建设和后现代主义的解构观念之间，于是，波普主义成为这个时代的一种自然的风格选择。

In order to avoid these drawbacks, a design has been provided in which the driving chain is a round-link chain with horizontal links having a very small vertical and horizontal clearance of motion and with vertical links having a large vertical and horizontal clearance of motion in the hollowed section in which they are guided.

The historical meanings of earlier Arab national movement are that: First, the rising of nationalism in Arab world pioneers a new routine different from traditional one; Second, the new conception of constructing country causes Arab people to be separated from formulation of religion / empire, and be immersed in construction onrush in neoteric world; Third, the grown-up of nationalism awakens and changes Arabs traditional idea, and adapts them to the new one of national development; Fourth, the thoughts of nationalism rebuilds Arab nation in the background of new era; Fifth, the babyish Pan-Arabism especially in King Era establishes development contrail of Arab world.

早期阿拉伯民族主义运动的历史意义：第一，民族主义在阿拉伯世界的兴起开辟了一条有别于传统的民族发展新路；第二，新型国家构建理念使阿拉伯人逐渐走出宗教／帝国范式，融入近代以来世界范围内的民族国家构建洪流；第三，民族主义的崛起唤醒和改造了阿拉伯人尘封已久的民族自我意识，使其适应新时期民族发展的需求；第四，民族主义思想在新的时代背景下重塑了阿拉伯民族；第五，早期特别是&王政时期&的泛阿拉伯主义运动虽然看起来显得那么稚嫩，但却奠定了阿拉伯世界的发展轨迹：在民族目标上，谋求民族独立或自由成为全民族各阶层的首要共识；在民族统一的问题上，独立的民族国家间的全面合作逐渐取代政治上的统一；在泛阿拉伯主义的另一面旗帜——巴勒斯坦问题上，巴勒斯坦战争预示着武力解决方案的失败，承认以色列、通过和平谈判的方式解决这一问题成为唯一的选择。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。

For non-intense beams,particle trajectory can be obtained by multiplying linear transport matrices. For nonlinear transport of intense beams,the influence of space-charge effect on beam transport needs to be taken into account,and self-consistent solution should be derived because of the interaction between charged particle distribution and space charge field. In the program,components and currents are divided into equal intervals,respectively,and each interval is treated as a uniform solenoid field.

程序在计算非强流脉冲束流的线性传输时，粒子的轨迹通过矩阵的直接相乘计算得出；程序在计算强流脉冲束流的非线性传输时，需要考虑束流中的空间电荷效应对束流传输的影响，在束流运动过程中，空间电荷场也在不断地变化，而且粒子运动的轨迹与空间电荷势又是相互依赖的，因此需要求得一个自洽的解，先把元件分成若干均等的区间，把电流分成若干等份，后采用束流电流迭代与元件区间迭代的计算方法。
