Acquisition of the fuse alarm digital variables : during idle , repeat acquired the 120 routes 48 analog data , process sample statistic for each rote acquired active - high 熔丝报警开关量信息的采集:在idle时候循环采集120路开入数据,对各路采到的实时高电平次数进行样本统计。
After explaining the both at hone and abroad relevant results of study , the whole paper . taking the approaches of sample statistics , comparison study , and many other approaches of prediction , has carried on the deep discussion on how to establish the relationship between quantity aid quality in the development of higher education , how to establish the scientific view of higher education in quality , how to construct the rational structure of higher education , and how to raise the efficiency in school management of higher educatin and realize that the scale , quality , structure , effectiveness of higher education develop harmoniously and allsidedly 本文就湖北省高等教育大众化的规模、结构、质量和效益问题进行了全面系统的分析。全文采取了抽样统计法、比较研究法、以及多种预测的研究方法,对国内外有关的研究结果进行阐述后,对如何确立高等教育发展中数量与质量的关系、如何确立科学的高等教育质量观、如何构建合理的高等教育结构、以及如何提高高等教育办学效益,实现高等教育规模、质量、结构、效益全面协调发展等问题,进行了深入的探讨。
In this paper , taking one of the special processes - chromic acids anodizing for example , such administration methods as the key points control and the quality performance administration system for surface treatment process have been setup by process analysis and key points seeking . as for the complicacy of the quality control on metallurgical special processes and the huge statistic data , the quality information system of surface treatment have been established on the bases of computer database . this paper brings out the systematic evaluation way to setup reception test items by taking the reception test results as evaluation basis and sampling statistics as rules 本文以铬酸阳极氧化表面处理工艺为研究对象,通过工艺技术分析、寻找关键特性、建立对关键特性的控制等工作,研究建立了表面处理工艺动态质量管理系统;针对冶金特种工艺质量控制的复杂性及统计数据量大等特点,建立了以计算机数据库管理为基础的表面处理信息及处理系统;为解决冶金特种工艺原材料入厂复验任务重的困难,建立了以原材料入厂复验的试验结果为评价基础,以抽样统计方法为依据的原材料入厂复验项目优选系统等。
Being different from traditional neural network or nn , nn is based on traditional statistics , which provides conclusion only for the situation where sample size is tending to infinity , while svm is based on statistical learning theory or slt , which is a small - sample statistics and concerns mainly the statistic principles when sample are limited , especially the properties of learning procedure 支持向量机( svm )是九十年代中期发展起来的新的机器学习技术,与传统的神经网络( nn )技术不同, svm是以统计学习理论( slt )为基础, nn是以传统统计学理论为基础。传统统计学的前提条件是要有足够多的样本,而统计学习理论是着重研究小样本条件下的统计规律和学习方法的,它为机器学习问题建立了一个很好的理论框架。
