基于Multisim的计数器的仿真实现

计数器在电子系统中有着非常广泛的应用,计数器在现代数字系统中主要是通过对时钟脉冲的个数进行计数,从而可以实现测量、计数以及控制的功能.本文运用反馈清零法和反馈置数法,以74LS160计数器和门电路组成7进制、6进制计数器以及60进制计数器为例,用Multisim软件分析任意进制计数器的设计方法.

Investment-specific shocks and external balances in a small open economy model

Abstract.  We set up a standard small open economy business cycle model driven by government spending shocks, neutral productivity (TFP) shocks, and investment-specific shocks. The model is calibrated to quarterly Canadian data and its predicted moments and sample paths are compared with their Canadian counterparts. We find that the model captures the dynamics in investment and in the trade balance better than special cases of the model where either one of the productivity shocks is omitted. More specifically, the model matches the variance of the trade balance-output ratio, its correlation with output and its autocorrelation. It also matches the output-investment correlation.

On the Formation ＆ Growth of Chengdu-Chongqing Economic Strip

According to the essential features of urban economic strips, this paper is intended to point out that Chengdu-Chongqing strip has so far been an urban area in geographic or spatial sense, but not an urban economic strip in economic sense. On further basis of analyzing several problems existing in the developrnent of Chengdu-Chongqing economic strip, some countermeasures are correspondingly put forward hereafter.     

农业高新技术投资项目风险评价

The agricultural high-teeh investment project （AHIP） is eharaeterized by technology-intensive, high risk and great profit. This article analyzes essential factors of the risks of the agricultural high-tech investment projects and the traditional risk evaluation method of agrtcultral projects. We think that the applications of the sensitivity, analysis and probability ore defer. Therefore; this article introduces a structural model to evaluate the risks of the agricultural high-tech investment projects and the system of the concrete evaluation indexes.     

论国有企业财务机制的重构

国有企业改革至今,还普遍存在着国家作为国有企业所有者的所有权虚设和政府越权干预企业的现象,加上企业治理结构不完善,形成“内部人控制”的局面,会计信息严重失真,国有资产严重流失。但入世后,要求政府转变职能,不

美国地方政府体制的"碎片化"评析

美国地方政府体制的“碎片化”，是地方政府数量庞大、功能重叠、边界不清的形象称谓。多元民主理论认为它有利于保障公民的直接政治参与，公共选择理论则将其视为表达公共经济领域中消费者偏好的制度工具。另一方面，碎片化的地方政府体制所产生的整体效益低下、部分地方政府民主程度与效率不够、以及无力应对社会问题等弊端，招致了大量的批评。
