脉冲波形的微分变换

本文叙述的脉冲波形微分变换,是一种专门用于某些脉冲波形在t—u坐标系和u-du/dt坐标系之间实现数学变换的方法。其目的主要在于准确求出不规则电脉冲随幅度变化的速率变化。文中介绍了几种常用的数学函数的微分变换,以及实现这种变换所用的微分器和实验装置,在双踪示波器屏幕上能够显示出速率变化图形。这种图形,在医学上对研究肌肉和神经电脉冲是非常有用的。     

计算网络时域变化响应的卷积方法

本文提出了一种计算线性动态网络微分灵敏度和大变化灵敏度的统一方法。该方法编程简单、计算量小,特别适合多端口的网络。     

From Unjust Markets to Just Distribution

The tendency of the market to concentrate wealth on small groups of individuals and to over-react to shocks to the economy requires the invigilation of the state to protect the disadvantaged. Saul Estrin, Lecturer in Economics at the London School of Economics, contends that socialist acceptance of market efficiency should not be extended to its inequitable distribution of resources and power.

Negative Child Tax for Economic Efficiency

The Governments recent review of the social security system proposed to continue the payment of Child Benefit to rich and poor parents alike. Alexandra Hardie or the University of Exeter, examines the disincentive effects of the current system of universal child benefit and calls instead for its replacement by selective benefits to improve incentives to employment, simplify administration and concentrate state assistance where it is required.     

Centralisation is no Solution

Although the US structure of government encourages the activity of presure groups more than in the UK, argues Rosalind Levaćić of the Open University, orchestrated campaigns to put pressure on government have spread in Britain, especially in education and health, where they will now prevent direct central government control of resources from being as effective as decentralising control to individual consumers/voters.     

A Market Policy for Socialists?

Socialists ought to welcome the efficiency and freedom of choice that markets bring, and be wary of the deficiencies of the state, according to lan Forbes, lecturer in Politics at Southampton University. But the freedom of choice claimed by the 'New Right' thinkers for their economic system would itself be attenuated by the operation of markets. Market socialism thus requires an institutional pluralism of both market and non-market elements.     

‘Thatcherism’ without Thatcher?

Have Mrs Thatcher's more radicol policies prepared the ground for a substantial restructuring of the British economy? Or is she merely responding to fundamental economic changes that are stimulating a response in the political market? Nigel Ashford, Senior Lecturer in Politics of the North Staffordshire Polytechnic, contrasts the Government's timid policy response with the electorate's increasing desire for economic liberalism, and examines the gulf between Conservative economic policy and the more truly radical ideas Mrs Thatcher is sometimes thought to promulgate.
