China Particuology 2006年第5期4卷 238-242页

The properties of the porous granules produced by agglomeration of catalytically grown carbon nanofibers were investigated in this work. The single pellet crushing strength of the granules is high, e.g., 1.6-2.5 MPa. They have high specific surface areas, averaging 72-141 m^2·g^-1, and the majority of their pores are mesopores or macropores. The adsorption at 298 K of benzene or phenol on the granules is much lower than that on activated carbon and depends not only on the specific surface area of the carbon material but also on the sewing structure of the granules and the morphology of the carbon nanofibers. Treatment in dilute nitric acid appreciably reduces such adsorption.

A novel 2×5 model of insert-plug piezoelectric quartz crystal tumor marker micro-array immunosensor constructed with screw clamp apparatus has been developed for quantitative detection of the tumor markers such as alpha-fetoprotein (AFP),carcino-embryonic antigen (CEA),prostate specific antigen (PSA),and human chorionic gonadotropin (hCG) in serum,in which every crystal unit can oscillate independently with the stability of±1 hertz (Hz) in air and±2 Hz in *** response characteristics of Pz tumor marker micro-array immunosensor such as temperature, time-cost,reproducibility and specificity etc were also *** detection ranges for AFP,CEA,PSA,and hCG obtained by Pz micro-array immunosensor were 20 ng/ml～640 ng/ml,1.56 ng/ml～50 ng/ml,1.25 ng/ml～50 ng/ml,and 2.5 mIU/ml～250 mlU/mi respectively with the coefficient of variance (CV) less than 5%.No cross-reactivates with other tumor markers in serum were *** results of AFP,CEA,PSA,and hCG obtained by this method from 68 serum samples were in good agreement with those given by chemiluminescence immunoassay with the correlation coefficients of 0.92,0.90,0.91,and 0.94 *** Pz immunosensor regenerated by urea solution could be reused for five times without appreciable loss of response ***,the proposed insert-plug immunosensor provides a rapid, sensitive,specific,reusable,convenient and reliable alternative for the detection of tumor markers in clinical laboratory.

Aiming at the rural-urban background, the paper research content is that the outdoor space design adjusting to aging population. It is noteworthy that the “empty nest” becomes a social phenomenon in China. The community and the village are the are population most centralized region, it is also the main places that old man consume their leisure time. Outdoor space design should be suitable for the local natural climatic conditions and cultural customs. Outdoor space in Hunan of China appropriates local opened space. The high quality design of outdoor space will create conditions for social endowment and self-help endowment. Outdoor activity space is closely linked with the old people’s quality of life. Function of outdoor space includes contact and the exercise as well as manual labor and pastime. Outdoor space design strategy consists of barrier-free design, identification design and activity space. The paper thinks that: “Doing to older, joy to older” is the highest state of old age. This needs the joint efforts of the family and community, needs to assume by physical space. The outdoor is the main site of activity for old man. Taking exercise, accompanying with others or pets, association and manual labor are the main content to outdoor space design.

In this paper, a series of experiments were conducted to investigate the drying of typical municipal solid wastes (MSW) in a muffle incinerator. From the experimental drying characteristic curves, the effects of temperature on drying process were observed to be more obvious in the low temperature region than in the high tem- perature region in muffle incinerator. At a specified drying temperature, drying time was highly dependent upon the packed waste thickness, having an exponent rela- tion with the thickness. When the drying temperature increased or the thickness of potato bulks was diminished, the maximum drying rate reduced. Based on the first-order reaction, activation energy (Ea), and factor A of potato and cabbage were determined.

随着新冠肺炎疫情在欧洲的不断蔓延,欧洲经济风险与社会风险交织,促使欧洲各国不得不推出大规模的财政刺激计划,债务风险随之开始凸现,引发各方广泛关注。现阶段欧元区国家债务风险具有以下特点:政府债务杠杆率高企,企业部门债务风险持续上升,债务货币化特征突出。欧元区国家的债务风险将严重损害长期经济增长,易引发债务危机,削弱欧央行独立性,加剧内部发展失衡等。为此,我国应吸取欧洲的经验教训,警惕欧债危机重演,防范过度负债陷阱,审慎对待债务货币化。
