Consequently, the circle viewed as a point still has Circle as a type description because the pointer in its .class com- ponent has not changed. draw is a selector function, i.e., it will take whatever argument is passed as self, proceed to the type description indicated by .class, and call the draw method stored there.

这个被看作是点的圆依旧是Circle类型的，因为其类型描述结构中的。class指针成员没有变化。draw是选择子函数，也就是说，它能接受任何以self参数传来的值，找到由。class指向的类型描述符，并且调用存储在那里的方法。

The core idea of the method is to reduce the Hough cumulative dimension of the circle detection based on classical Hough transform, and convert the threedimensional statistical parameter based on the traditional circle Hough transform to two-dimensional parametric statistics about the center of a circle and one-dimensional statistical parameter about the radius of a circle.

给出了一种基于Hough变换的同心圆检测方法，其核心思想是降低经典Hough变换圆检测中的Hough累积维数，将经典Hough变换圆检测时的三维参量统计，转变成基于弦中点的圆心和半径的参量统计。

The words "Pai-Chang"or "Pai5 Tiunn5" have many meanings But when used in traditional opera or music and explained as a kind of formal musical performance they are only applied in Taiwanese Peguan and Nanguan cultural circle particularly in Peguan circle There are two kinds of characters of "Pai-Chang" in terms of the function of the performance namely artistry and folk custom In Tainian city "Pai-Chang" which refers to the formal vocal performance without makeup and acting; nevertheless is used by the amateur actors' organizations of Peking opera as well Such a phenomenon raises two questions: first of all Although Peking the origin of Peking opera has vocal performance of Peking opera "Pai-Chang" is never used either artistry or folklore therefore how does this jargon hand down to the Peking opera circle in Tainan city ?

「排场」(pai5 tiunn5或ㄆㄞˊㄔㄤˇ)一词，用於戏曲音乐方面，做音乐的正式演出型态解释者，为台湾南北管文化圈所特有，其中又以北管最常使用。其以表演目的或弁郧荌粥洃嚏A可分为艺术性与民俗性两种。然而，在台南市及其周边的京剧文化圈内，亦使用有「排场」(pai5 tiunn5或ㄆㄞˊㄔㄤˇ)此一语汇，也指京剧的「正式清唱演出」。本研究动机基於对目前仅见於台南市及其周边之民俗性京调排场的两点疑惑：其一，按京剧的形成地－－北京，虽亦有京剧的清唱演出，然不论为艺术性或民俗性，北京人都不称为「排场」，那麼台南市京剧圈的排场语汇是如何得来的呢？代表了何种意义？
