非本质的

The system parameters are determined by optimizing an output-error cost function. To deal with the non-uniqueness of the fully parameterized state-space system, a projected gradient search algorithm is presented by restricting the update of the parameters to the tangent space to the manifold of observationally equivalent state-space systems. The sufficient condition to employ L-M algorithm for optimizing parameters is also introduced. The proposed hierarchical optimization identificationmethod includes two steps: First, the parameter search direction is determined by the proposed adaptive L-M projected gradient approach; Second, the optimum step size is computed according to a line search method.

通过极小化输出误差目标函数获得了系统参数估计；提出了正交梯度搜索方法用于解决系统参数的非唯一性问题，正交梯度搜索的本质是在输入-输出等价类相切平面的正交垂空间更新系统参数；给出了用 L-M 算法进行参数优化的充分条件；提出的系统参数递阶优化辨识方法包括两步：首先用给出的自适应 L-M 算子正交梯度方法确定参数优化方向；其次由一维搜索方法计算最佳步长。

In order to distinguish the evolutionary changes of the architectural systems in the modern process, therefore the modernization process is the major axis of discussing the dissertation of the manners of this study.

从现代化过程中探讨台湾建筑论述的演变后，所揭橥的是台湾建筑论述的演变历程中，由於在世界舞台上的角色并非为主导者地位，本质上是被动的，受制於不同政权的兴替，而非全然为建筑专业者的自我觉醒，而导致台湾建筑论述普遍缺乏主体性。

Islam, on the other hand, represented a radical breakaway from the Arab paganism that preceded it;Islamic law is the result of an examination, from a religious angle, of legal subject matter that was far from uniform, comprising as it did the various components of the laws of pre-Islamic Arabia and numerous legal elements taken over from the non-Arab peoples of the conquered territories.

伊斯兰教，在另一方面，代表着一种本质上的决裂，与过去存在的阿拉伯异教信仰；伊斯兰法是考察的结果，从宗教的角度，对法律的主题内容，这些内容远远不是统一的，而这些法律内容实际上是由前伊斯兰阿拉伯国家法律的各种因素，以及由被征服土地上非阿拉伯民族的大量法律因素所构成。

认知的中介本质、符号的非中立性以及符号体系必须拥有的三大元功能不仅为区别图像与文字奠定了认识论基础，而且也为探讨它们之间的关系提供了可能性，同时，更是理解虚拟现实的有效途径。

The third part introspects the educational ideas of public philosophy courses in colleges, including the introspection on the philosophy nature of non-philosophy, the introspection on the purpose idea of the philosophy isolation from people, the introspection on the process idea of simple philosophy education and the introspection on the function idea of the useless theory of philosophy.

第三部分，对高校公共哲学课教育理念进行反思。包括非哲学化的哲学教育本质观的反思，哲学与人疏离的哲学教育目的观的反思，单一化的哲学教育过程观的反思，以及哲学教育无用论的功能观的反思。

Thus, convergence, not divergence, seems to have characterized the cultural development of the American Colonies in the eighteenth century. Thus, without the cultural diversity represented by the American South, the culture of colonial America would certainly have been homogeneous in nature. Thus, the contribution of southern colonials to American culture was certainly overshadowed by that of the Puritans. Thus, the culture of America during the Colonial period was far more sensitive to outside influences than historians are accustomed to acknowledge.

This paper pointed out that the essential of geoherbs is continuers quantities variation at population level, geoherb's populations are different in gene frequency with the others'; geohersm are quantitative trait loci controlled by multi-gene or combination with multiple-gene and major gene at individual level.

指出道地性的遗传本质在居群水平通常是个量变的过程，它与种内其他非道地药材区别主要表现为居群内基因型频率的改变；在个体水平表现为微效多基因控制的数量遗传，或是微效多基因和主基因联合控制的数量性状。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

In the second section, the paper talks about the relationship between supremacy right of water right and that of real right, which shows that the nature of water right comes as a result of the supremacy of the neediest benefit instead of that of real right in the field of water right.

第二节则分析了水权优先权与物权优先权之间的关系，揭示了水权优先权的本质其实是最紧缺利益优先规则的体现，而非物权优先性规则在水权领域的反映。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
