概念论

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. Secondly, in this part, we will introduce the notation of average geodesic curvature for curves in the hyperbolic plane, and investigate the relationship between the embeddedness of the curve and its average geodesic curvature.

其次，对双曲平面上的曲线引入平均测地曲率的概念，并讨论双曲平面上凸曲线的嵌入性与它的平均测地曲率之间的关系，其目的是为了将双曲平(来源：ABC论84文网www.abclunwen.com)面上曲线的性质与欧氏平面中曲线的性质作一些对比；最后，我们利用Minkowski支撑函数构造了一类新的非圆的光滑常宽曲线，其目的是想回答有关常宽曲线的一些未解决问题如是否存在非圆的多项式常宽曲线？

In this paper, I draw on the Foucauldian notion of 'heterotopia' to illuminate Shanghai schoolgirls' expressive and performative enactment of a she-self desiring another she in their journey through schooling.

在本论文中，我利用福柯的"另类帮"的概念来观察在上海女中学生。在读书阶段，她们的女性自我对另一个女性有怎样的欲望？这种欲望如何表达和表现的？

From the perspertive of holism,the article discussed the concept and form of civilization,and put forward new definition of the concept of civilization and society.

Based on the concept of zero-path tracking in homotopy which is generalized into minimum of energy function path tracking and considering that different homotopy path has greater impacts on convergence speed, a new method is put forward——the non-line homotopic BP algorithm.

本文在将同伦论中的零点路径跟踪概念推广到对多层前馈神经网络能量函数极小点路径跟踪的基础上，注意到不同的同伦路径对收敛速度的影响，提出了一种改进算法——非线性同伦BP算法。

The concept of zero-path tracking in homotopy is generalized into minimum-path tracking and a new method for the training of multi-layer perceptron is thus put forward──the homotopic BP algorithm. An analysis is made on the convergence property of the proposed method.
