The variation of neutral surface height and effective thermal coefficient with in.
得出了排风量、排风温度随内部热源高度的变化,分析了不同内部热源高度下的速度场和温度场,得出了中和面高度、有效热量系数随内部热源高度的变化。
This paper states the present calculation methods of ventilation and infiltration airflow in large spacebuiding Points out that the sticking point of calculating airflow is the confirmation of wind pressure coefficient andheat pressure coefficient and the neutral plane position.
叙述了目前大空间建筑通风与渗透风量的计算方法,指出了计算的关键是风压系数、热压系数和中和面高度的确定,介绍了它们现有的确定方法,对今后的研究提出了建议。
The differences between the gases of upper and lower coalbeds of fold neutral plane are analysed by means of the different strain features of upper and lower rock strata in fold neutral plane,providing scientific basis for forcasting coalbed gas.
利用褶皱中和面上、下岩层的不同应变特点，分析了处于褶皱中和面之上与之下的煤层在背向斜部位瓦斯赋存大小的差异性。
Anticlines and synclines are the basic deformation forms of sedimentary basins,as well as neutral planes are the important interface of strata deformation.
背斜、向斜褶皱构造是沉积盆地的基本形变,中和面也是地层变形中的重要界面,在传统的石油地质理论中,一直忽视了这一重要界面。
