平面把

Factually, what Gombrich was interested in is to describe how a painter turns a 3D object to a 2D painting with the 3D illusion by means of his or her eyes, with the support from various theories of modern psychology, sociology and philosophy (e.g., the visual prevision theory of Gibson, falsificationism of Popper, iconology of Erwin Panofsky, etc.), after the research on a great number of works, artists and related classics and literature.

其实，贡布里希的兴趣是在各种现代心理学、社会学与哲学的支持下(吉布森的视觉预知理论、波普尔的证伪主义、潘诺夫斯基的图像学等等)，通过对大量作品、艺术家与相关的经典和文献的研究来仔细描述人是如何用自己的眼睛这个器官，把一件处在三维当中的物体转变成二维上的平面绘画的，而这平面上的二维又具有三维空间的错觉感。

The contrastive research is fully conducted from Chapter Four to Chapter Six. Chapter Four studies negation in English and in Chinese at the lexical level, which can be further divided into three sublevels, namely, morpheme, word, and phrase. Chapter Five studies negative sentences, explicit negative form at the syntacticlevel. And the study covers the classification, syntactic feature, nonassertive/assertive items, scope/focus of negation, two important tendencies, and some common special negative sentences. Chapter Six focuses on the implied negative sentences in English. According 10 devices employed to achieve negation, implied negative sentences are divided into four categories, namely, implied negative sentences by grammatical devices, by semantic devices, by rhetorical devices, and by pragmatic devices.

从第四章到第六章具体地展开了英汉否定对比研究：第四章的研究在词汇平面上进行，分为语素、词语和词组：第五章对比研究了在句子平面上英汉否定中的显式现象—否定句，主要涉及否定句句法特征和分类、句型转换、否定范围和否定焦点、全句否定和局部否定、转移否定、双重否定、部分否定和全部否定、强调否定和否定问句回答等方面；第六章集中研究了英语含蓄否定句，按照一个含蓄否定句采用何种手段实现意义上的否定进行一下分类，把含蓄否定句分为四类—通过语法手段实现的含蓄否定句，通过语义手段实现的含蓄否定句，通过修辞手段实现的含蓄否定句，通过语用手段实现的含蓄否定句。

Planar point set the minimum inclusive circle, that circle with a minimum point of the plane are all incorporated.

详细说明：平面点集的最小包容圆，即用一个最小的圆把平面内所有的点都包容在内。

An algorithm based on triangulation is presented. First, 3D range data is projected on square domain in the plane.

首先对三维深度数据在矩形平面域上投影，并对平面域内的采样点按Delaunay优化准则进行三角剖分，然后把网格节点变换到三维曲面上，从而实现了煤堆三维立体图的显示。

We will refer to the plane of the graph as the x-y plane.

我们将把图的平面作为x-y平面。

An complete algorithm for reconstruction of polyhedral model from orthographic views based on combination of independent loops is proposed.

提出了一种基于平面独立环路组合的多面体视图三维重建完整算法，即先把三视图中的每个视图分解成一个个独立的不可再分的平面独立环路，然后从三面视图的三个环路组中逐个取出可能的环路组合按构造实心体几何方法构成局部实心体模型，最后将局部实心体模型组合成整体实心体模型。

In the last chapter, by introducing the isochronous center of real systems into complex planar and defining complex center and complex isochronous center, a concise linear recursion formula for period constants is given, necessary and sufficient conditions of complex isochronous center (the Time-Angle Difference Theorem) proved, conditions of real systems with linearizable center and saddle treated unitedly and the isochronous center conditions discussed fully for a class of real planar cubic systems.

在第七章，通过把实系统等时中心引入复平面研究，定义了复中心和复等时中心，给出了等时中心周期常数计算的简明的线性递推公式，证明了等时中心判定的充分必要条件，统一地处理了实系统具有可线性化的中心和鞍点条件，并对一类实平面三次系统的等时中心条件进行了完整研究。

Want to solve this problem, main method is an issue of plane of translate into of solid geometry problem, the method that uses planar analytic geometry next will study this contrail.

要解决这个新问题，主要方法是把立体几何新问题转化为平面新问题，然后利用平面解析几何的方法来探究这个轨迹。

In the first part, we will first deal with the strong Bonnesen-style inequality (2.1.3) for closed convex curves in the plane (the numbers of formulae and references are those of them in the context below). Bonnesen had first proved the weaker inequality (2.1.2) in [12] and several years later, he outlined in his monograph [13] various Bonnesen-style inequalities including (2.1.3), he considered, however,(2.1.3) as a direct consequence of Kritikos theorem for convex bodies in higher dimensional Euclidean spaces,. Here, we will give an independent proof of the existence for inequality (2.1.3), and by the way, give an estimate on the width of the bi-enclosing annulus of closed convex curves in the plane.

具体地讲，在第一部分中，首先讨论平面上闭凸曲线的强Bonnesen型不等式(2.1.3)(公式的编号和参考文献的编号引自后面的正文)，Bonnesen在文[12]中先证明了较弱的不等式(2.1.2)，几年以后，在他的著作[13]中，讨论了多种Bonnesen型不等式，其中包括不等式(2.1.3)，不过，他把(2.1.3)作为高维欧氏空间中凸体的Kritikos定理的直接推论，我们这里对不等式(2.1.3)给出独立的存在性证明，并且还对平面闭凸曲线的bi-enclosing环的宽度给出了一个估计。
