Hitherto. there have been more than ten kinds of formulas for calculating statistical parameters of correlation extending series. All of the formulas were derived from some hypotheses. Though not contradictory to the statisti- cal theory. the hypotheses are inconsistent with stochastic characters of sam- ple series. This paper derives new formulas according to the statistical theory of pa- rameter estimation instead of basing on any hypothesis. Living example veri- fies the formulas to be applicable.

相关展延系列统计参数计算公式,至今已提出十余种。所有的公式都是在一定假设条件下推演出来的.固然这些假设与数理统计理论并不矛盾,但它们并不符合实际样本系列的随机特性。 本文根据参数估计的统计理论,不作任何前提假设,推导出展延系列统计参数新的计算公式,并用实例验证公式的适用性.

In this paper,a load prediction model suitable for regional power network is proposed.This model developed does not simply depend on all the preceding data recorded.It also takes into consideration the users' demand and the social-economical development of a region.The increasing of the supplied power must keep pace not only with the former but also with the latter.The main content of this paper deals with the establishment of an economic-power model.Besides,in this paper,an economic-electric power model is...

In this paper,a load prediction model suitable for regional power network is proposed.This model developed does not simply depend on all the preceding data recorded.It also takes into consideration the users' demand and the social-economical development of a region.The increasing of the supplied power must keep pace not only with the former but also with the latter.The main content of this paper deals with the establishment of an economic-power model.Besides,in this paper,an economic-electric power model is proposed for predicting the load of a regional power network.With the consideration of its stochastic character,the random time series method is employed in the process of model establishment

本文研究了一种适用于地区电网规划的中、长期负荷预测方法。这种方法不是单纯地把历史记录数据作为唯一的预测依据,而是把电力负荷的需求与社会、经济发展紧密联系起来,后者是电力负荷增长的根据,两者必须保持同步增长。所以建立经济—电力模型是本文的主要任务;另外,还注意到电力负荷具有随机性的特点,对此我们采用随机时间序列分析法加以处理。

This article emphasizes the analysis of the stochastic character of dynamic stresses on the BJ-663 van's body structure in different speeds and on different paths during testing. The test was carried out at Hai Nan Experimental Ground and ordinary highways. CF-500 Frequency spectrum analyzer, SW-160 and SD-142 stress wave analyzer were used for data processing. It is concluded as follow: The speed as well as the roughness of highway was of the important function in the intensive reliability test and the stress responses of the element of the body structure presented a low frequency narrow band so that during the body analysis,the low exponents in main mode can be calculated and high exponents neglected. When the van was driven on different paths, sensibilities of stress response on each measuring point of the elements of the body according to positions were quite different so that the strength test of the body must be taken on different paths for overall exam etc.

本文以BJ-633A型旅行车车身为研究对象,在海南试车场及一般公路上进行了动态测试,将获取的随机信号在CF-500频谱分析仪、SW-160和SD-142应力波分析仪上进行了数据处理,着重分析了该车以不同车速在各种道路上行驶时,车身结构动应力的随机特性以及对车身结构强度的影响。指出路面不平度和车速是强化车身结构可靠性试验的重要因素。
