The experimental results show that solids through long- column type distributor is most even-distributed;its distribution deviation is below 5%as gas flowrate is greater than 60m￣3 /h;distribution deviation decreases with increase of gas flowrate and appropriate increase of column height.
试验结果表明，长柱形旋流分配器的分配性能最好，当气相流量大于６０ｍ￣３／ｈ时，分配偏差可小于５％；增大气相流量，适当增加柱形旋流分配器的柱体部分高度，可降低分配偏差。
Western economic theorists use three different approaches to explain the observed phenomena:first are the models of distributive preferences,which assume that people care about the final distribution,e.
西方学者主要从三种不同的角度来解释涉他行为:第一,分配偏好模型,这类模型关注分配结果是否均等、公正、有效;第二,互惠偏好模型,这类模型认为关注他人是出于对他人的回报或报复;第三,未来合作偏好模型,这类模型认为关注他人是为了未来的合作,当存在合作前景时,人们将会更慷慨。
