The economic development model of the Taihu area of Jiangsu Province in this article is set up on the basis of the previous research and practical situation of this area.(Here, Y means the total value of agriculture output, x_1 implies the input of labor which is expressed as the work recompense of commun members, x_2 signifies the cost of production, x_3 indicates the material technical equipment which is represented as the amount of electricity used in the countryside, x_4 means the proportion of the output value of industry and sideline in the total value of agriculture output.)The author forecasts the development of agriculture economics by means of the schedule trend model of each economic increase element on the basis of economic development model. By 2000, the total agriculture output value would have reached 17.663 million yuan ±15%,increasing at a rate of 7.07 per cent a year, i.e. to about four times. The contribution of technology progress and developmnet of integrative agriculture indicates that there is no evitable relationship between "a larger base of economy and a lower rate of development".The development rate of agricultural economics often shows an accelerative trend in this area.

本文在前人研究的基础上,结合江苏省太湖地区的实际情况,建立和编制经济发展模型: Y=0.9219x_1~(0.4329)·x_2~(0.6433)·x_3~(0.0874)·x_4~(0.1412) (其中:Y为农业总产值;x_1为社员劳动报酬,用以代表投入的劳动量:x_2为生产费用;x_3为农村用电量,用以代表物质技术装备水平;x_4为工、副业产值占农业总产值的比重) 通过经济发展模型,并借助于各经济增长的时序模型,对农业经济发展进行预测。到本世纪末,农业总产值将达到176.63亿元±15%,年递增7.07%,约翻两番。由于技术进步的重大贡献和综合农业的发展,说明“基数大、速度低”并无必然的联系。本区农业经济发展速度经常存在加速的趋势。

A new approach, ihe Equivalent Energy Function (EEF) Method for power system probabiliotic modeling is presented in this paper. The method completes convolution and deconvolution by employing electric energy directly so that probabilistic modeling is considerably simplified. The EEF method is not only more efficient than any other method available in the area, but also more flexible in treating assigned energy units. An approximate deconvolution algorithm and a LOLP formula are also given which enable the carrying out of a product modeling to be even faster. Numerical examples demonstrate that the algorithm presented in the paper is simple, efficient and more accurate.

本文为电力系统随机生产模拟提出了一种新方法——等效电量函数法(EEF法)。该方法直接用电量进行卷积计算,使生产模拟计算大为简化.EEF法不仅在常规卷积计算时速度比目前世界上采用的方法快,在处理分段机组、水电机组等问题时也比较灵活.文中还给出了电力不足概率(LOLP)的估计公式及卷积的简化计算方法. 文中的数字例表明,该方法不仅速度高、精度高,而且程序简单.
