Using DC and AC poling methods, three groups of polarized PZT/P 70/30composites have been prepared by poling only the ceramic phase(1), both ceramic and polymerphases in the same(2) and opposite(3) directions. Piezoelectric coefficients of group 1 compositesincrease as the PZT content increasing, while for group 2 composites, the piezoelectric coefficientschange the sign with increasing PZT content because piezoelectricity of copolymer is increasinglycompensated by that of PZT, and PZT content for zero-〓 isn't that for zero-〓. The experimentdata of both group 1 and 2 composites agree well with EMT-Shin model.

对复合材料的压电性能：只极化PZT粒子相的复合材料的压电系数随陶瓷分数的增大而增大，PZT粒子相与共聚物基体同向极化的复合材料的压电系数由于两相效应的部分抵消，随陶瓷含量的增大，发生符号的改变，且〓和〓零点不重合，它们与EMT-Shin模型都符合较好；而两相反向极化的复合材料的压电系数由于AC反向极化会导致陶瓷相极化程度的下降，导致实验值和理论预期偏差较大，尤其在PZT粒子高含量区。

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.

首先，作者针对机器人的设计要求提出了多个方案，对其进行分析比较后，选择其中最优的方案后用Pro/Engineer和AutoCAD软件进行了机器人模型结构设计；其次，进行了运动学分析，用D-H方法建立了坐标变换矩阵，推算了运动方程的正、逆解，运用VC++制作了正、逆运动学求解的求解界面；并且用微分变换法推导了速度雅可比矩阵；在基于机器人的运动学的轨迹规划中，通过在操作空间的规划，提出了归一化因子来求解中间结点，通过它可以使求解中间结点变得更简单，并且赋予这些中间结点实际的物理含义，对于规划中精确性和实时性的矛盾，提出了以误差极限法和反向插值法来解决的方法；为了减少规划过程中计算量，在关节空间进行三次样条插值；然后借助图解法进行工作空间分析，作出了实际工作空间的轴剖图。

提起德彪西音乐的魅力，人们常常会想起钢琴曲《月光》那缓缓向下漂浮的透明的柔和光芒；《格拉纳达之夜》中稍现即逝的吉他拨奏与远方响起的响板声所点缀的西班牙情调；《水中倒影》中反向进行的和弦对位构成的音乐模式象征水波荡漾、涟漪泛起，不断扩散的动态；交响素描《浪花游戏》则以短小动机、欢快的乐句，色彩明朗的和声，弦乐颤奏的背景勾勒出波涛喧闹、浪花跳跃、水珠欢笑、阳光闪烁的嬉戏画面。

The latter three strategies are new and also the paper's three innovative points. First of all, appeal the law to prohibit reversed payment, unify this with the BOLAR exception, and promote the drugs into the market as soon as possible. Secondly, put the public health, medicine patent and the IPRs protection of traditional knowledge and the genetic resources together. Through giving the traditional knowledge and the genetic resources IPRs protection to treat the developed countries' medicine patents, they can settle the public health crisis. Finally, the legal mechanism of Prior Consent is a new strategy that Brazil proposed for the purpose of protecting the public health, which divides the examination of patent applications for pharmaceutical products and processes between two federal agencies, National Institute of Intellectual Property and National Sanitary Supervision Agency. ANVISA has the obligation to render the final decision, granting or denying a patent.

其中前四种措施是国际社会上一直以来倡导的主要措施，后三种是新的解决公共健康危机的法律措施，其创新点在于：第一，呼吁将禁止反向支付纳入法律，并与BOLAR例外相结合使用，促进仿制药品的尽快上市；第二，将公共健康、医药品专利以及传统知识和遗传资源的知识产权保护三者紧密相连，通过对传统知识和遗传资源予以知识产权保护来应对发达国家的医药品专利；第三，&事先同意&法律制度是巴西提出的一种旨在保护公共健康，应对医药专利的新的法律制度，该制度规定凡是涉及医药品专利的申请都必须经过国家知识产权局和国家公共卫生监督局的公共审查，并且国家公共卫生监督局有是否授予专利的最终决定权。

These cases may indicate that the separatrix frequency region of bidirectional electron beams are within a large braodband from 250 to 2900 MHz and the originating ranges are in a very small (4 to 100 MHz) and different bands.

介绍云南和北京天文台射电频谱仪观测到的3个对偶的米波--微波Ⅲ型爆发，估计了双向电子束起源的频率和高度，3个事件分别揭示了在正向和反向漂移爆发之间的分界频率(约为250，1300和2900 MHz)，它们指出了一个致密的电子加速源，在这个源中产生了向上和向下两个方向注入的电子束，从这些事例可以表明不同事件的双向电子束的分界频率有一个相当大的范围(250-2900 MHz)，而它们的起源范围却是在一个很小的(大约4-100 MHz)和不同的频段范围内。

The 329 bp terminal inverted repeat sequence can't form the conserved fold-back secondary structure as that of many Streptomyces linear replicons. Lacking of typical Streptomyces tap/tpg locus for te-lomere replication, pPR2.3c encodes a protein with two domains resembling the telomere associated protein of Strepto-myces and helicase of Haemophilus respectively. No typical Streptomyces iteron-rep locus for replication from the cen-trally located origin, two DNA fragments containing almost all pPR2 were cloned and introduced by transformation into S.

其端粒末端反向重复序列的长度为329 bp，不能像多数链霉菌的线型质粒那样能形成保守的&折返&的二级结构。pPR2虽然没有参与链霉菌端粒复制的保守的tap/tpg基因，但是pPR2.3c基因编码了一个双结构域蛋白，分别同链霉菌的端粒复制相关蛋白Tap和嗜血杆菌的解旋酶具有相似性。pPR2缺少典型的链霉菌重复序列-复制基因区段，将几乎覆盖全长pPR2的两段DNA进行克隆后，不能转化变铅青链霉菌。

After Huang Qu senior official yellow Jinlong looking pensive stopping, also in a low voice saying:"Knows, on the Earth 60,000,000 year ago dinosaur exterminate, it is said is because at that time a diameter reached 200 kilometers planetoids to hit Saturn high speed, caused the Saturn entire stratum and the earth's crust receives the undulation, and caused the fierce reverse volcanic eruption, finally acted according to the near several centuries the continually exploration research to indicate, Saturn periphery several satellites, and even the giant beautiful saturn's ring, possibly all was creates by this direct hit, moreover most surprising was, spouted the Saturn parent substance together after the burning hot Saturn lava material coagulation, formed the diameter reached 30 kilometer hit fragment, after is hit unexpectedly Saturn fierceSways the movement, flung the Saturn orbit rapidly ......"

黄区长官黄金龙若有所思的停了停之后，又低声的说道：&知道吗，地球上6000万年前的恐龙灭绝，据说就是由于当时一颗直径达200千米的小行星高速撞击土星，导致土星整个地层和地壳受到波动，并引起剧烈的反向火山喷发，结果根据近几个世纪的持续探索研究表明，土星外围的几个卫星，乃至巨大美丽的土星光环，可能都是由这次直接撞击造成的，而且最令人惊讶的是，一块喷出土星母体由炙热的土星熔岩物质凝固后，形成的直径达30公里的撞击碎块，竟被撞击后土星剧烈的摇晃运行，急速甩出了土星轨道……&
