SYNTHESIS OF NEW HIGH MOLECULAR WEIGHT AND REACTIVE LADDERLIKE POLYSILSESQUIOXANES

引用

Chinese Journal of Polymer Science 2000年第5期18卷 459-463页

作者： Neal tai-sheng Chung Institute of Materials Research and Engineering Singapore 117602 Singapore

Ladderlike polychloropropylsilsesquioxane (CP-T) was first synthesized by 'stepwise coupling polymerization'. The molecular weight of CP-T is as high as 1.7 x 10(5). It is a tough, elastic reactive ladderlike polymer and has good heat-resistant and adhesive properties. CP-T can further react with many nucleophilic reagents to generate new ladderlike reactive polysilsesquioxanes, which can be used as potential precursors in the synthesis of functional ladderlike polymers.

Porous Cube-like In_2O_3 Nanoparticles and Their Sensing Characteristics toward Ethanol

引用

Journal of Materials Science & Technology 2008年第4期24卷 667-674页

作者： Chih-Chia HUANG Chen-sheng yeh Natl Cheng Kung Univ Dept Chem Tainan 70101 Taiwan

Porous cube-like crystalline In2O3 nanoparticles with an average diagonal length of 34.8 nm were fabricated by a laser ablation-reflux process to form In（OH）3, followed by a calcination treatment to yield porous In2O3. HRTEM （high-resolution transmission electronic microscopy）, XRD （X-ray diffraction）, BET （Brunauer-Emmett-Teller）, and XPS （X-ray photoelectron spectroscopy） analysis were used to characterize their crystalline structures, grain sizes, surface areas, and surface compositions. The as-prepared porous in-dium oxides were tested for their sensing properties toward ethanol. Non-porous In2O3 nanopowder （about 40 nm） was also examined in order to compare the results with the as-prepared porous In2O3 nanomaterials. The porous In2O3 exhibited much better performance than that of non-porosus In2O3, and showed enhanced sensitivity with a lower detection limit than other reported In2O3-based materials when exposed to ethanol. Good gas sensitivity and linear behavior as a function of ethanol concentration were observed in the porous In2O3 nanoparticles.

Livelihood differentiation between two villages in Yesanpo Tourism District in China

引用

Journal of Mountain Science 2017年第11期14卷 2359-2372页

作者： HUANG tai XI Jian-chao GE Quan-sheng Department of Tourism Management Soochow University Institute of Geographic Sciences and Natural Resources Research Chinese Academy of Sciences(CAS)

The rapidly developing rural tourism industry in China has deeply influenced the livelihoods of rural households. This study compares the impact of rural tourism development in poor areas on the farmers' livelihoods, based on the Sustainable Livelihoods Framework proposed by the United Kingdom's Department for International Development. Gougezhuang, a tourist village, and Jiaojiekou, a non-tourist village, both located in Yesanpo Tourism District in the state-level povertystricken Laishui County, Hebei Province, were selected as case studies. The livelihood models of the two villages show great differentiation after 20 years of tourism development. Gougezhuang Village has been driven by the tourism industry and farmers are employed locally, enjoying a relatively higher-income life, with a developmental livelihood model. In contrast, farmers in Jiaojiekou Village earn their living mainly by leaving home to work in the city. They have a low income, with a survival livelihood model, supported by part-time business. Considering that the two villages are adjacent and have similar development backgrounds, the analysis results indicate that rural tourism has an apparent locationspecific effect on poverty alleviation and socioeconomic development, but the development ofrural tourism is limited regarding large-scale poverty alleviation efforts in poor areas. To implement a propoor-tourism strategy and achieve sustainable development, it is necessary to implement comprehensive management measures to change the local conditions of rural settlements and make full use of the spillover effect of tourist consumption.

Stem flow of seed-maize under alternate furrow irrigation and double-row ridge planting in an arid region of Northwest China

引用

Journal of Integrative Agriculture 2015年第7期14卷 1434-1445页

作者： BO Xiao-dong DU tai-sheng DING Ri-sheng TONG Ling LI Si-en Center for Agricultural Water Research in China China Agricultural University

Maize is widely planted throughout the world and has the highest yield of all the cereal crops. The arid region of North- west China has become the largest base for seed-maize production, but water shortage is the bottleneck for its long-term sustainability. Investigating the transpiration of seed-maize plants will offer valuable information for suitable planting and irrigation strategies in this arid area. In this study, stem flow was measured using a heat balance method under alternate furrow irrigation and double-row ridge planting. Meteorological factors, soil water content （e）, soil temperature （Ts） and leaf area （LA） were also monitored during 2012 and 2013. The diurnal stem flow and seasonal dynamics of maize plants in the zones of south side female parent （SFP）, north side female parent （NFP） and male parent （MP） were investigated. The order of stem flow rate was： SFP〉MP〉NFP. The relationships between stem flow and influential factors during three growth stages at different time scales were analyzed. On an hourly scale, solar radiation （Rs） was the main driving factor of stem flow. The influence of air temperature （Ta） during the maturity stage was significantly higher than in other periods. On a daily scale, Rs was the main driving factor of stem flow during the heading stage. During the filling growth stage, the main driving factor of NFP and MP stem flow was RH and Ts, respectively. However, during the maturity stage, the environ- mental factors had no significant influence on seed-maize stem flow. For different seed-maize plants, the main influential factors were different in each of the three growing seasons. Therefore, we identified them to accurately model the FP and MP stem flow and applied precision irrigation under alternate partial root-zone furrow irrigation to analyze major factors affecting stem flow in different scales.
