Examples
- In early 2001 , there were strong winds , flying dust , flying sand and sandstorms in hexi corridor and part of inner mongolia , which influenced part of the north china , including beijing
2001年年初，河西走廊、内蒙古部分地区出现大风、浮尘、扬沙和沙尘暴天气，并影响到包括北京在内的华北部分地区。 - A large area of bare sandland distributed in beijing and its surrounding areas is one of sand source areas which contributes to high - frequent sand storms in beijing in recent years , whereas increasing of surface coverage condition is one of effective measures to lessen local blown - sand activities
摘要北京及其周边地区分布的大量裸露沙荒地是北京近年来沙尘暴频发的主要沙源之一，而增加其地表覆盖状况则是遏止就地扬沙起尘的有效措施之一。 - 2 ) from the analysis of the aerodynamic parameters and turbulent flux transfer under different synoptic conditions we achieve the conclusion that on sands raising and sandstorm days turbulent momentum and sensible - heat fluxes are important exchange factors in the boundary layer , with turbulent exchange stronger in sandstorm weather than both on fine and sand raising days . prior to the occurrence of such an event , in particular , the super - adiabatic instability in the near - surface boundary will reinforce sandstorm weather condition . 3 ) atmospheric turbulent diffusion parameters z and y have apparent daily variation
沙尘天气下以亲地壳元素为主的气溶胶元素浓度均高于背景大气和浮尘天气，而且沙尘天气强度愈强，元素浓度的增加愈显著；背景大气、浮尘天气条件下亲地壳元素的浓度一般在10 ~ ( - 1 ) 10 ~ 0 g m ~ 3量级，扬沙、沙尘暴时一般达10 ~ 1 g m ~ 3量级，特强沙尘暴时高达10 ~ 2 g m ~ 3量级。 - Gas - solid two - phase flow is existed widely in multiphase flow system , for example , desert sand in nature , fuel transportation in field of chemical industry , metallurgy , energy sources and foodstuff , and so on , as well as pneumatic conveying and dust treatment of materiel in bulk ( i . e . sands , corn and plastic granula etc . ) . in addition , sulfureted bed , whirlwind dust - exhaustion , sedimentation room and filtration process are involved with gas - solid two - phase flow
气固两相流在多相流体系中普遍存在，例如，自然界的大漠扬沙，化工、冶金、能源和粮食等领域的燃料配送，散装物料(如沙子、谷物、塑料粒)的气力输送和粉尘处理等，硫化床、旋风除尘、沉降室及过滤过程中也会涉及到气固两相流。
