 This paper discusses the basic theory and application of the 5G14500 system, which is a one bit micro pro cessor used in automatic control.The small 5G14500 system presented here has not any jumping hardware. However, because of its software, the jumping, conditional branching and subroutine capacities can still be implemented in the system. This is a LoopAroundWhile structure in which two or more independent programs can run simultaneously.It is less expensive, but it does call for a clear understanding... This paper discusses the basic theory and application of the 5G14500 system, which is a one bit micro pro cessor used in automatic control.The small 5G14500 system presented here has not any jumping hardware. However, because of its software, the jumping, conditional branching and subroutine capacities can still be implemented in the system. This is a LoopAroundWhile structure in which two or more independent programs can run simultaneously.It is less expensive, but it does call for a clear understanding of the programming reguiremdnts.  笔者曾采用5G14500系统一位微处理机解决某项目中的自动控制问题。该自动控制一般需要设置子程序堆栈,并且要一定的存储空间。笔者设计了一套软件,不需要任何转移硬件,而能对外部装置进行五套不同的动作控制。这样就大大简化了结构,降低了成本,也提高了可靠性。为了便于阅读,本文从软件和硬件的结合,理论和实践的结合来加以讨论。  The air line from fans, blowers or air compressors is always accompanied with strong noise.In this paper,the characteristics of the air flow noise had been diagnosed firstly, then the basic theory and applications of every element which will attenuate the air flow noise, such as the energy radiation along the pipe, change of the sectional area and the direction of the air line, especially a sudden enlargement or bend of the flow line and a sidebranch resonator are discussed and their effects are... The air line from fans, blowers or air compressors is always accompanied with strong noise.In this paper,the characteristics of the air flow noise had been diagnosed firstly, then the basic theory and applications of every element which will attenuate the air flow noise, such as the energy radiation along the pipe, change of the sectional area and the direction of the air line, especially a sudden enlargement or bend of the flow line and a sidebranch resonator are discussed and their effects are predicted.The sound attenuation and enclosure of the air accumulator or air tank which usually is an end element of the air flow line has been improved.Thus, this paper has provided some practical methods on the control of air flow noise.  本文在分析空气压缩机及鼓风机的气流噪声特性的基础上,对气流沿程衰减的各环节,例如沿程声能发散,管路截面变化,特别是突然扩大,旁支容积构成共振腔,弯接头等作了理论探讨,最后对一般管路输出终端——贮气罐的消声与隔声作了改进。 本文为控制气流噪声提供了具体办法。  This paper is devoted to the study of the basic theory and applications of probabilistic metric spaces (PMspace). In this paper the topological structure and properties for PMspace are considered. The conditions of metrization and the form of metric functions for PMspaces, Menger PMspaces and probabilistic normed linear spaces (PNspace) are given and the characterizations of various probabilistically bounded sets are presented. As applications we utilize these results obtained in this... This paper is devoted to the study of the basic theory and applications of probabilistic metric spaces (PMspace).
