The breakthrough curves of benzene and water on modified activated carbons（ACs） were ***-programmed desorption（TPD） experiments were conducted to measure the TPD curves of benzene and water on modified and unmodified ACs and to estimate the activation energy for the desorption of benzene on the modified *** with unmodified ACs,two modified ACs were prepared by using two different types of silane,designated by KH560 and *** results showed that the activation energy for the desorption of benzene on KH560/AC and 1706/AC was higher than that on unmodified *** addition,the activation energy for the desorption of water on KH560/AC and 1706/AC was lower than that on unmodified *** breakthrough curves of benzene obtained from the experimental observations under different humidity conditions were compared with the results of the TPD *** results show that the modified ACs are less affected by water,whereas the unmodified ACs are more affected by water,indicating that surface modification by organosilane compounds can improve the adsorption of benzene on the activated carbo,which weakens the adsorption of water.

阿米什人自18世纪初迁居美国至今,一直恪守古老的宗教传统,远离和规避主流社会与现代文明。阿米什人认为现代教育所教授的内容和价值观与他们的生活方式有尖锐的冲突,于是创建了自己的教区学校,建立了一种符合其传统核心价值观念的教育。阿米什人的基础教育有效地加强了他们的文化认同感,实现了其文化的生存和延续,这对我国当代少数民族基础教育有一定启示意义。

The genetic diversity and relationships of 14 Bactrocera dorsalis(Hendel) populations consisting of 180 individuals collected from 10 provinces of South China,Tailand,Hawaii,Philippine,and Laos were analyzed with 13 microsatellite *** results showed that:(1) 88 alleles were obtained over the loci and the average allele number per locus was 7.66;.(2) A relatively high level of genetic diversity was revealed:P = 98.35%,Nei’s = 0.6575,and I = 1.3213.(3) UPGMA cluster analysis indicated that the populations from Guangdong,Taiwan and Hainan gathered into one clade,while the populations from Guangxi,Fujian,Yunnan,Hunan,Sichuan,Chongqing and Guizhou formed the other one.(4) Mantel test revealed that there were positively correlation between genetic distance and geographical distance.
