Using corn straw and soybean straw , the characteristics of the decaying process and the remainders , the difference of soil fertility status and soil humic acids character in different using ways are studied by normal analysis combined with energy analysis , thermal analysis ( dta , tg , dig ) and infrared spectrum analysis ( ftir ) 本文以玉米秸和大豆秸为腐解材料，通过常规分析方法结合能态分析、热分析( dta 、 tg 、 dtg )和红外光谱( ftir )分析研究了荒漠绿洲生态系统下残体的腐解特征以及不同利用方式下土壤养分和土壤腐殖质的变化。
The normal analytic technique was adopted to mensurate the basical nutrients such as total n , total p , total k , available n , available p , available k , organic matter , ph and so on . meanwhile , various techniques were employed to mensurate the soil dissoluble carbon , finally the technique of water saturating - h2so4 - agso4 - circumfluence - feso4 titration was used in this experiment 测定土壤的基本养分状况全氮、全磷、全钾、速效氮、速效磷、速效钾、有机质、 ph等采用常规分析法，对土壤可溶性碳的测定方法进行了多方面的探索，最后采用水提? h _ 2so _ 4 - ag _ 2so _ 4回流? feso _ 4滴定这一方法。
Presents starting link and system organization of fan ’ s inspects status and fault diagnosis . the system collects data through data acquisition system , inspects fan ’ s status with monitoring soft , establishes routine and fault data bases , and calls routine analysis daughter system , and in the end diagnoses the fault , observates equipment ’ s operating mode ; finds fault type and cause . with the assistance of the diagnosis system , the economy and safety of factory is greatly improved 通过数据采集系统对信号进行采集与处理,利用监测软件实现风机状态监测,建立常规数据库和故障数据库以及调用常规分析子系统进行故障诊断等手段,观察设备运行状态,找到故障的类型和原因,作为决策的依据,从而提高了设备的经济性和安全性。
The analysis methods that the system adopts are introduced from the view of time - domain , frequency - domain and time - frequency - domain . emphasis is focused on the correlation integral analysis method . the measurement parameter of signal nonstationarity defined on the basis of correlation integral is discussed , and the feasibility that it is used to diagnose the faults of dynamic nonstationarity as the characteristic parameter is also investigated with a case 本文将系统中所实现的常规分析方法从时域分析、频域分析和时频域分析三个角度分类进行了说明，重点介绍了相关积分分析方法，探讨了基于相关积分定义信号非平稳性的度量参数，并结合实例探讨了该参数作为特征参数诊断动态过程非平稳类故障的可行性。
In the first part , demonstrations have been focused on the theoretical foundation of the information analysis in the cash flow statement . followed by the second part is the structural issue of the conventional analysis in a company ' s cash flow statement . then the analysis in a company ' s cash flow statement has been further made through the whole financial position of the company 本文主体由四部分组成，第一部分主要论述现金流量表信息分析的理论基础；第二部分主要探讨现金流量表常规分析的体系构建问题；第三部分主要从企业财务状况的全局入手对现金流量表进行分析；第四部分主要从企业战略角度对现金流量表进行更深入的分析。
Abstract : an imidazole - catalyzed acylation method of phthalic anhydride is applied to the determination of hydroxyl values of reinforcing agent is211 . the analytical error is 5 . 0 10 - 3 . the relative standard deviation of the method is less than 0 . 04 and its coefficient of variation is not more than 5 . 0 10 - 3 . hydroxyl values determined in different batch samples meet the design requirement completely . this method is rapid and simple , it is adaptable to conventional analysis 文摘:以咪唑催化邻苯二甲酸酐酰化的方法测定增强剂is211的羟值，准确度高，分析误差为5 . 0 10 - 3 ；方法精密度好，标准偏差小于0 . 4 ，变异系数不大于5 . 0 10 - 3 ，测定不同批号试样的羟值完全符合商标值，方法快速、简便，适用于常规分析。
