Abstract : in the research of internal combustion engine , recordingin - cylinder pressure and temperature is an essential technique to study the thermal cycle of internal combustion engine . the combustion analyzer developed in this study will give both the measurements at sampling points per crank angle or sampling cycle , calculate and show the real time parameters which decide the working process of internal combustion engine , such as pressure accelerating rate , indicateed mean effective pressure , cycle - to - cycle variation , heat release rate , etc . compared with the imported congeneric products , the analyzer has many advantages such as chinese interface , low price , easy operateing , convenience in maintainance and easy upgrading 文摘:为了测录内燃机缸内的压力及温度，开发了一种内燃机燃烧分析仪.该分析仪由国产高速数据采集卡及自行开发的控制软件组成.它不仅能精确设置每度曲轴转角内采样点的个数和采集循环数，而且在采集过程中能实时计算和表征内燃机工作过程的压力升高率、平均指示压力、循环变动率、放热率等参数.经实际使用以及与国外产品相比表明，此分析仪具有全中文界面、价格低、操作简单、使用维护方便、功能便于扩充等优点
They are agricultural productive materials price growth rate , sown area of grain crops growth rate , grain yield per area growth rate - , natural disaster covered grain areas growth rate , net grain import change rate , grain reserve change rate , population growth rate , per income growth rate , city and town population growth rate , food industry production value growth rate , year - end pig number growth rate , medical & pharmaceutical and textile industry production value growth rate , grain marketization degree , inflation rate using the previous year as base year ( preceding year = 100 ) , public grain purchases price growth rate , investment in agricultural science and technology growth rate , investment in agricultural infrastructure growth rate , growth rate of graduates number from agriculture , forestry , science & technology universities and colleges and specialized secondary schools , government expenditure for agriculture and agricultural credit growth rate , international grain price growth rate , rmb exchange rate growth rate , last grain price growth rate , economic crop price growth rate , , meanwhile , a new method is attempted to be used in this paper and the grain price early - warning problem is transformed into machine learning problem by introducing statistic learning theory and svm method which are gaining popularity in machine learning field at present in the world 在此基础上，筛选出23个警兆指标：农用生产资料价格增长率、粮食播种面积增长率、粮食单产增长率、粮食受灾面积增长率、粮食净进口量变化率、粮食储备变动率、人口增长率、人均收入增长率、城镇人口增长率、食品工业产值增长率、猪年末头数增长率、医药纺织工业产值增长率、粮食市场化程度、以上年为基年的通货膨胀率、国家粮食定购价格增长率、农业科技投入增长率、农业基础设施投入增长率、农、林、科技高校大、中专毕业生人数增长率、财政支农资金比重及农业信贷增长率、国际粮食市场价格增长率、人民币汇率增长率、上期粮食价格增长率、经济作物价格增长率。同时论文在预警方法上作了新的尝试，把粮食价格预警问题转换成一个机器学习问题，引进当前国际上机器学习领域中比较热门的统计学习理论和支持向量机方法，用顺序回归算法对历史数据进行学习建立了粮食价格预警模型。
It just disintegrates the economic growth , reveals industrial competitiveness " contributions to the growth , evaluates the actual changes and contributions to industrial growth in the changes of demand , technology , investment and import / export from the seven industries and gets the better positive conclusion 对经济增长进行因素分解，揭示产业竟争力对经济增长的贡献，并评价六大产业的需求变动、技术变动、投资变动及进出口变动这四大因素的实际变动率和对产业增长的贡献，得到具有实践指导意义的实证分析结论。
The movement of the social security assistance index of prices ( " ssaip " ) and the rate of change in the actual prices of all the commodities and services in such index in each month of the past two years ; and whether there were opposite movements between ssaip and consumer price index ( a ) in the past two years ; if so , of the reasons for that （四）过去两年，每月社会保障援助物价指数（社援物价指数）变动的情况及该指数中所有商品和服务价格的实质变动率，以及社援物价指数和甲类消费物价指数有否出现相反变动的情况；若有，原因为何？
3 . this paper analyzes the existing guide lines of the association of industries , indicates the deficiency of “ the quotiety of middle input ” . this paper founds the guideline of “ the changing quotiety of middle input ” , which could reflect distinctly the change of quantity and structure of the middle input 3 .分析了现有产业关联指标体系,指出“中间投入率”指标在反映内容上的不足,从结构变动的角度提出了“中间投入变动率”指标;该指标能够显著的反映投入产出表中间投入率的变动和中间投入结构的变动。
