Provides the curves of soil vertical pressure coefficient to calculate vertical load and discusses the calculation method and its application conditions for vertical or lean walls in pipe channels and for rigid or flexible pipes. 给出了计算垂直荷载的土壤垂直压力因数曲线,讨论了考虑沟槽为直壁沟槽或斜壁沟槽、管道为刚性或柔性管道时的垂直荷载计算方法及适用条件。
Following such a point of view, a principle of reduction of NO, by means of a dual-stage vertical dense / lean combustion of pulverized has been described in this paper. 基础于这一观点,该文论述了煤粉的双级垂直浓淡燃烧能够降低NOx排放的原理。
Study on a dual vertical dense / lean combustion of pulverized coal in order to decrease no_x emission and stabilize combustion 煤粉双级垂直浓淡燃烧降低NOx排放及稳燃技术的研究
According to that the gradient edges in normal images were more than horizontal and vertical edges, a new focus measure method ( lean operator ) derived from gradient edge detection was proposed. 根据自然图像中斜边缘多于水平和垂直边缘的特点,提出了基于斜边缘检测的对焦评价算子(lean)。
The composition and vertical distribution profile of microbes in different tobacco growing soils ( lean moisture soil from Xiangcheng, Henan Province and rich yellow soil from Xingshan, Hubei Province ) were studied. 利用不同肥力土壤(低肥潮土和高肥黄壤,分别取自河南襄城和湖北兴山),研究了正常生产管理条件下烟田土壤微生物的组成及垂直分布特征。
