Grass of willow leaf horsewhip belongs to herb of perennial of horsewhip female division, formal name: Verbena Bonariensis illustrious name: Purpletop Verbena, alias: Long bine horsewhip is South-American horsewhip grass, careless, originate in South America formerly of Brazil, Argentine and other places, the flower is cyme, small tubular flower is worn be born at spending cauline coping, open amaranth or lilac flower, along with spends a bine to consider individual plant tall to make an appointment with 100-150 centimeter, liu Xie is crossed opposite, the primary part of a historical period after sowing is elliptic brim somewhat notch, beautiful bine is smoked tall the Xie Zhuai after is the slightness leaf that be like willow shape the brim still has pointed notch, the bine is a square this a little bit very special, entire individual plant has cilium to feel the feeling that pricks thorn a bit, the meeting in ground of be out of office is cross of plant of fringy horsewhip female division with a few congeneric flowers, so often a few inflorescence upright among Yu Jusan and fringy model state plant appears.

柳叶马鞭草属于马鞭草科多年生草本植物，学名：Verbena bonariensis英名：purpletop verbena，别名：南美马鞭草。长茎马鞭草，原产于南美洲，花为聚伞花序，小筒状花着生于花茎顶部，开紫红色或淡紫色花，连同花茎算株高约100-150公分，柳叶为十字对生，播种后的初期叶为椭圆形边缘略有缺刻，花茎抽高后的叶转为细长型如柳叶状边缘仍有尖缺刻，茎为正方形这点十分非凡，全株都有纤毛摸起来有点刺刺的感觉，在野地里会与一些同属花为穗状的马鞭草科植物杂交，所以常有一些花序介于聚伞与穗状的中间型态植株出现。

To fulfill the requirements of reliability, extensibility and adaptability, this dissertation proposes a Holon-based control architecture for flexible manufacturing shop floor using a bottom-up design approach. The inner structure of component Holon, the relationships of data and functions among Holons, the model of message transfer and the basic specification of communication language are described in detail. Then, from the aspect of software architecture, a formal description and analysis of the proposed architecture is conducted by First-order Polyadic pi-Calculus.

针对可靠性、可扩展性和适应性等要求，提出了基于Holon的柔性制造车间控制体系结构，描述了组件Holon的结构模型、数据和功能关系、信息传递模型和通信语言基本规范，并从软件体系结构的观点出发，运用π演算对其进行了形式化描述和分析，为基于Holon的体系结构设计和分析奠定基础；3。
