在完全的膺矢量表示下，HVH定理遭到了相当大程度的破坏，从而体现出基态关联效应对单核子性质的重要性，并与非相对论BHF理论方法得到的结论一致，因而完全的膺矢量表示要优于膺标量表示。

Also in the 3-D space, we assign the 20 amino acids to 20 vertices of the dodecahedron. By the symmetry of the dodecahedron we obtain 3-D representation of 20 amino acids, and 3-D graphical representation and the corresponding numerical sequence of protein sequences. And similarity and dissimilarity analysis based on the invariants of graphs and characteristics of numerical sequences are given for nine RNA secondary structures of RNA-3 of virus. We construct sequence phylogenetic tree of a group of cytochromes C protein.

在DNA三联体密码子表示的基础上，在半复平面上给出了蛋白质序列的非退化的2-D图形表示，同时利用复向量的主要特征—模和相位，给出了蛋白质序列的一种数值刻划，进一步在3-D空间里，把20种氨基酸分别分配给正12面体的20个顶点，根据正12面体的对称性得到了20种氨基酸的3-D表示，进而得到了蛋白质序列的3-D图形表示和对应的数字序列，并利用图的不变量和数字序列的特征比较了9种动物的神经元

This paper discusses such problems which are easily solved incorrectly in limitedteaching as, segment function is uncertain not to be elementary function, elementary function is un-certain to be continuous in its field of definition, unlimited variable is uncertain to be infinity, theinfinitely many infinitesimal is uncertain to be infinitesimal, the multiplication of two non- infinitesi-mal is uncertain not to be infinitesimal.

1分段函数不一定不是初等函数我们知道初等函数的定义是：常数和基本初等函数经过有限次的四则运算或复合，用一个解析式表示的函数叫初等函数。教材中的定义强调的"有限次"和"一个解析式"，使很多同学产生"非有限次"和"非一个解析式"的函数就不是初等函数的误解。例1f=ceox，s xx！0为分段函数，但也可以表示为f=e12(x-x2")+cos12(x+x2#"$)-1，故为初等函数。

In noncommutative scalar field theories, the appearing of nonplanar diagrams is related to permutation symmetry of field functions in the interaction Lagrangian, while in NCQED we can not arbitrarily change the positions of field functions in the interaction Lagrangian because different positions of the field functions correspond to different representations of the gauge group.

这里需要特别指出的是NCQED的非平面图产生的原因与非对易标量场根本不同，非对易标量场非平面图的产生是和相互作用拉氏量密度中场函数间位置的置换对称性有关，而在NCQED中我们不能随便交换相互作用拉氏量密度中场函数的位置，因为场函数的不同位置对应着规范群的不同表示。

In accordance with the situation that the damping was the non-classical damping,the structure was asymmetric,and random wind spectrum was irrational fraction wind spectrum,the equations obtained were decoupled with the complex mode theory.

建立运动方程，用第一振型将主体结构展开，针对非经典阻尼和非对称结构以及脉动风谱为非有理分式风谱的情况，运用复模态理论将所得方程进行解耦，获得了以第一振型表示的结构随机风振响应的解析解。

A general matrix perturbation method for complex modes using singular value decomposition;2. The modal character,the error of the substituting by real modes and the best way to extract real modes from complex modes are discussed.

This means that, in most cases, only a very small part of an object will lie within this area. If we want to observe the object in detail, we have to move the fixation point frequently to make the different parts of the object lie within the central area. In addition, with such a small central area, the separation of foveal and peripheral channel becomes meaningless. Consider all the above aspects, we propose in this thesis a visual computing model based on selective attention mechanism.

针对上述问题，本文的模型引入选择注意机制，并将之建立在非均匀采样表示与处理的基础上，我们提出了一种可以随视觉任务变化的可变结构的非均匀采样信息表示方法，并通过它将后继的视觉处理分成相对独立的中央和周边通道，分别完成对感兴趣物体的识别和注意点的快速转移，后者相当于对感兴趣物体的一个粗定位过程。

The junk rating is the percentage of the submitted message that was not useful (i.e., material that was not observational records, observational header or e-mail header). Many messages arrive with junk ratings of more than 50 percent (in some cases, more than 90 percent!). If you get a poor junk rating, you should examine what you are actually sending and try and cut out some of the junk that some PC mailers seem to insert.

用百分比表示，表示你上报的无用信息的多少（比如：非观测记录内容，非报告头或EMAIL文件头等）很多报告包括50%以上的垃圾信息（有些甚至超过90%），如果你发现你的上报有太多的垃圾，请自己检查你的报告，去掉不该添加的内容，有些邮件服务商会自动添加广告内容。

If the vessel comes into collision with another vessel as a result of the negligence of the other vessel and any act, neglect or default of the master, mariner, pilot or of the servants of the carrier in the navigation or in the management of the vessel, the owners of the goods carried hereunder will indemnify the carrier against all loss or liability to or the other or non-carrying vessel or here owners in so far as such loss or liability represents loss of or damage to or any claim whatsoever of the owners of said goods paid or payable by the other or non-carrying vessel or her owners to the owners of said goods and set off, recouped or recovered by the other or non-carrying vessel or her owners as part of their claim against the carrying ship or carrier.the foregoing provision shall also apply where the owners, operators or those in charge of any vessel or vessels or objects other than,or in addition to, the colliding vessels or objects are at fault in respect of a collision, contact , stranding or other accident.

如果该船生效相撞的另一艘船由于疏忽所导致的其他船只上的任何行为，疏忽或过失的船长，船员，引水员或有关人员的，承运人在航行或管理上的船只时，业主的货物进行以下，将赔偿承运人反对一切损失或责任单位或者其他或非进行船只或在这里的业主来说，这样的损失或负债的损失或损坏或任何赔偿可言的业主对他的商品支付或应付的，由其他或非携带容器或她的业主向业主表示，商品及对冲，收回或收回的，由其他或非携带容器或她作为业主的一部分，他们声称对船舶进行前述规定，也适用于业主，经营者或负责人的任何船只或船只或物体以外的，或除，撞击船只或物体都是有过错方面的碰撞，接触，搁浅或其他事故。

On the other hand, a service provider may receive many requests at the same time, and because of the limited resources, it can't serve all of them. Consequently, for both service requesters and providers, there is a challenge of selecting interaction partners. This can be achieved by our proposed one-to-many service negotiation model.

在这个模型中，利用模糊命题表示协商参与者对服务的约束，这些约束是非数值化的；使用效用函数表示对数值化的服务非功能属性的偏好，采用二者相结合的方法建模对服务非功能属性的偏好选择。

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
