The experimental flow field of a 3-stage fan at design speed was calculated,and the parameters distribution of diffusion factor,angde of incidence,and angle of deviation were analyzed.
利用该程序计算出某3级风扇在设计转速下的试验流场,并对扩散因子、攻角、落后角等参数的分布进行了分析。
Performance calculation codes with loss and deviation angle models were developed by using the methods mentioned above.
采用流线曲率法求解组合压气机的准三维流场,在叶片排前后缘及中间设置计算站,使用样条函数拟合流线;根据组合压气机结构特点,发展了适合其特性计算的损失、落后角模型及计算程序;将特性计算程序与导、静叶角度优化调节方案相结合,确定出不同设计转速下,导、静叶最佳调节角度组合。
The article analyses the cause of backward of 1500m race from match, body pattern, physical quality and training among the decathlon.
文章从比赛、身体形态、专项身体素质和训练4个方面,分析其落后的原因,认为项目速度力量的专项因素是决定1500m跑成绩落后的主要因素。
Consequently, the negative effects brought by backward education were presented in many aspects, such as the disorder of society, increasing criminals, backward agriculture production technique and obstinate and benighted social customs.
20世纪上半期的苏北农村教育相对滞后,导致其产生的原因主要有社会与教育界自身两大因素,而教育落后对苏北社会所产生的不利影响则表现在乡村社会秩序紊乱、匪化现象严重,农业生产技术落后,愚昧、落后的社会习俗依旧盛行等方面。
Some of these viewpoints are backward and blackguard but others are progressive.
本文从女性崇拜文化母题的演变角度， 分析了《西游记》所反映的妇女观， 既有其落后庸俗的一面， 也有其进步的一面； 既有对半原始男性优越意识的批判， 也有对男性文化原形题旨的继
