In this paper, we studied on critical current mode active Power Factor Correction technology, and did a detailed analysis and design on voltage reference circuit and analog multiplier circuit. 本文研究了有源功率因数校正技术中的临界导通模式的基本原理,并对其中的电压基准源和模拟乘法器做了详细的分析和设计。
The shift of onlap offlap points is a critical factor in sequence stratigraphic analysis and charting sea level curves. 地层超覆点的迁移是层序地层分析和海平面变化曲线编制的重要依据。
They advance a theorist construction of teacher performance through literature review, open-ended survey, critical incident interview and theoretical analysis. Then they test the construction of colleague appraisal results by confirmative factor analysis. 通过文献回顾、开放式调查、关键事件访谈和理论分析,提出了教师绩效的结构,通过验证性因素分析验证了同事评价教师绩效的结构。
In the pilot study, selection of items and factors in the questionnaire was base on comprehensive consideration with the response rate, critical rate ( CR) value, variation degree, correlation, factor analysis. 对预调查的数据采用应答率法、临界比率(CR)值法、变异度法、相关法、因子分析法进行项目和因子的筛选、分析。
And the relation of peak stress σ_m, peak strain ε_p, dynamic recrystallization critical strain ε_c with the temperature compensating deformation rate factor Z have been obtained by regression analysis, and then the condition and activation energy for dynamic recrystallization have been obtained too. 并通过回归分析得出峰值应力σm、应变εp、动态再结晶临界应变cε与温度补偿因子Z的关系式,从而获得动态再结晶产生的条件及动态再结晶激活能。
Establishing hierarchical structure of nodes and variables in the process, dangerous paths are arranged in terms of the relative importance degree, with high relative importance degree paths assigned as the critical situations which will decrease the effect of human factor to the analysis result. 建立过程中节点变量间的层次结构,将危险路径按照相对重要度进行排序,减少了人为因素对分析结果的影响。
