Simple model for gas holdup and liquid velocity of annular photocatalytic external-loop airlift reactor under both bubble and developing slug flow

Based on the momentum conservation approach, a theoretical model was developed to predict the superficial liquid velocity, and a correlation equation was established to calculate the gas holdup of an annular external- loop airlift reactor(AELAR)in the bubble flow and developing slug flow pattern. Experiments were performed by using tap-water and silicone oil with the viscosity of 2.0 mm²/s(2cs-SiO)and 5.0 mm²/s(5cs-SiO)as liquid phases. The effects of liquid viscosity and flow pattern on the AELAR performance were investigated. The predictions of the proposed model were in good agreement with the experimental results of the AELAR. In addition, the comparison of the experimental results shows that the proposed model has good accuracy and could be used to predict the gas holdup and liquid velocity of an AELAR operating in bubble and developing flow pattern.     

词根词缀记忆法

顾名思义,词根词缀记忆法就是通过记住词根词缀,并据此推测含此类词根词缀的新词的意思,加以强化记忆。词根有两种,一种是可以引申出许多同根词的词根,同时它也是一个独立的单词,例如ease作为独立单词,它又是easy,easily,easiness的词根。另一种是不能独立使用的词根,但它有一个基本意义,在不同的单词中意思大致相同。如:单词mirror(镜子)与mirage(海市蜃楼),这里的mir.这个词根相当于marvelous,surprising,是“奇异的,惊奇的”意思。所以,看看:mirror[mir.惊奇,-or表示物;令人惊奇之物,最初人们对镜子能映出自己的身影感到惊奇。]mirage[mi…

论海子诗艺的精神锻造

海子的诗歌精神和他的诗歌艺术是互不可分的共生体。从海子的诗学理解看,他具有精神大于技艺的倾向,他的诗歌精神是从生命元素和主体意志出发,对现代主义和后现代主义所体现的形式文明的清算和扬弃。但具体到诗歌实践中,他的诗歌又有着精彩纷呈的艺术性。
