| 1 | Traditional mortar represented by sticky rice lime mortar——One of the great inventions in ancient China显示文摘The development of traditional lime-based bond in ancient times was reviewed in this paper.It was proved by a lot of historical data that the application of organic materials in inorganic mortar was a sharp-cut characteristic during the developing process of construction gelled materials in ancient China.The important role sticky rice mortar ever played and the historical significance were revealed.Due to the excellent performance,such as high adhesive strength,good toughness,water-proof and so on,traditional mortar represented by sticky rice mortar should be one of the greatest technological contributions of the day in the world.Modern technology was employed in the study of the sticky rice lime mortar and the researching results of our laboratory and some researchers,including the compo-sition and the mechanism of solidification,were also presented.It was found that the sticky rice acted as a matrix of bio-mineralization which affected the microstructure of the calcium carbonate crystal and there was cooperation between sticky rice and calcite produced during the solidifying of the sticky rice mortar,which maybe lead to the excellent performance of the mortar.Because of excellent performance and importance in science,sticky rice mortar can be regarded as one of the greatest inventions in construction history of China.Relative research of sticky mortar will be of importance for the exploring of ancient momentous invention and the repairing of ancient construction. | YANG FuWei ZHANG BingJian PAN ChangChu ZENG YuYao | 2009 | Science China(Technological Sciences)2009,52,6: | 7 |
| 2 | Variation analyses of growth and wood properties of Larix olgensis clones in China显示文摘The growth traits(tree height, diameter at breast height, and stem straightness degree) and wood properties[wood density(WD), fiber length, fiber width, ash content(AC), lignin content, cellulose content, hemicellulose content(HEC), and holocellulose content] of 208 26-yearold Larix olgensis clones were analyzed. Except for WD and AC, there were significant differences(p \ 0.01) for all traits among clones. The phenotypic coefficient of variation and repeatability of all traits were 9.34–35.33%and 0.218–0.930, respectively. Tree height and diameter at breast height showed significant positive correlation;however, the correlation coefficients among growth characteristics and wood properties were mostly not significant.Ten clones(L70, L56, L82, L90, L59, L91, L61, L92, L86,and L64) were selected as excellent clones under a selection rate of 5%, using tree height, diameter at breast height,and stem straightness degree as evaluation indexes, providing genetic gains of 28.69, 17.96, and 0.67%, respectively. Ten clones(L88, L305, L59, L66, L253, L304,L277, L298, L248, and L293) were selected as excellent clones using wood properties as an evaluation index, with a selection rate of 5%, providing genetic gains in WD, fiber length, fiber width, cellulose content, and HEC of 4.14,3.64, 9.28, 6.77, and 9.61%, respectively. This study provides a theoretical basis for selecting excellent L. olgensis clones. | Shaopeng Yin Zhenhai Xiao Guohui Zhao Xin Zhao Xiaoyang Sun Ying Zhang Fuwei Wang Shuchun Li Xiyang Zhao Guan-Zheng Qu | 2017 | Journal of Forestry Research2017,28,4: | 6 |
| 3 | Experimental and Comparison Study on Two Solar Dish Systems with a High Concentration Ratio显示文摘Two high concentrating solar systems have been established with dish concentrator and plane-mirrors array concentrator.In the paper,the thermal performance has been experimentally studied with jet water cooling device and flat microchannel water-cooled device.The experimental results show that the maximum surface temperature difference of the dish concentrating system is greater than 20°C,while the plane-mirrors array system is lower than 4°C.It indicates that the plane-mirrors array concentrator has better uniformity.As the concentration ratio increases,the electrical efficiency of the concentrating photovoltaic system gradually decreases.When the concentration ratio is 200,the electrical efficiency of the photovoltaic system is 25%.The concentration ratio of 500 times or less is considered to be a suitable value,and then the electrical efficiency can still exceed 20%.It is found that the plane-mirrors array solar system is more suitable for the photovoltaic system than dish type system,which is only suitable for thermal power generation system. | CHEN Haifei LI Guiqiang YANG Jie ZHANG Fuwei LIANG Ming JI Jie | 2019 | Journal of Thermal Science2019,28,6: | 3 |
| 4 | An ethnobotanical study of forage plants in Zhuxi County in the Qinba mountainous area of central China显示文摘In the Qinba mountainous area of Central China,pig farming has a significant impact on the growth of the rural economy and has substantially increased farmer incomes.Traditional knowledge plays an important role in the selection of forage plant species for pig farming by local people.This study aimed to identify the forage plants used for pig feeding and to catalog indigenous knowledge regarding their use.During 2016 and 2017,ethnobotanical surveys and inventories were conducted in Zhuxi County,Hubei Province,China.Data were collected using semi-structured interviews,key informant reports,free listings,guided field walks,and participatory observations with 77 households in 16 villages in 13 towns/townships.The obtained data were analyzed using a relative frequency citation(RFC)index.Overall,145 wild forage plants from 91 genera and 31 families were recorded.The most cited families were Asteraceae,Polygonaceae,Urticaceae,Amaranthaceae,Fabaceae,Cruciferae,Caryophyllaceae,and Lamiaceae.Whole plants(75.9%)and tender leaves(12.4%)were the most frequently used parts of the plants.Most of the forage plants were herbaceous(88.9%).Almost all forage plants could be collected throughout the year(62.7%).Raw and cooked were the two main preparation methods.The most frequently cited species were Taraxacum mongolicum,Bidens pilosa,Sonchus oleraceus,Pilea verrucosa,and Pilea pumila var.obtusifolia.A total of 14 species were identified as the top forage plants in Zhuxi County based on their RFC values(RFC value greater than 0.5).Local people possess rich traditional knowledge about the utilization and management of forage plants for pig feeding.However,the maintenance of this traditional knowledge may be seriously threatened by changes in pig feeding modes and the lack of successors.Appropriate strategies and action plans have been suggested for the conservation of traditional knowledge associated with biodiversity and the sustainable use of forage species resources.These include 1)taking targeted measures to protect forage resources and associated traditional knowledge;2)strengthening research on the forage plants with the highest RFC values for nutritional value,digestibility,other functions,and ecological status;and 3)enhancing the identification of poisonous forage plants. | Jun Yang Jifeng Luo Qiliang Gan Leiyu Ke Fengming Zhang Hairu Guo Fuwei Zhao Yuehu Wang | 2021 | Plant Diversity2021,43,3: | 3 |
| 5 | Biomimetic fluorapatite films for conservation of historic calcareous stones显示文摘Fluorapatite protective films were prepared on marble substrates using a biomimetic method. By mimicking the mineralization mechanism of enamel, phosphorus and fluorine were introduced on the surface of the marble substrate. In the presence of a biological template, namely collagen, an integrated fluorapatite film was produced and the marble substrate was entirely covered. The prepared fluorapatite films were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive X-ray (EDX) spectroscopy. The performances of the fluorapatite films were evaluated by color changes, capillary water absorption, and acid resistance tests. The results revealed that the fluorapatite films had good compatibility with the marble substrate; the physical properties such as color and capillary water adsorption of the marble substrates were unchanged. The fluorapatite films also had good acid resistance and were stable even in heavy acid rain. | YANG FuWei LIU Yan ZUO GuoFang ZHU YuanCheng ZHANG BingJian HUA PingNing | 2012 | Chinese Science Bulletin2012,57,13: | 2 |

| 12 | Conservation of weathered historic sandstone with biomimetic apatite显示文摘The conservation of weathered historic sandstone with apatite was studied.Based on the growth mechanism of bone,calcium and phosphorus were introduced into weathered sandstone and then mineralized at room temperature.The conservation efficiency was investigated by scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy(EDX),transmission electron microscopy(TEM),selected area electron diffraction(SAED),X-ray diffraction(XRD),and compressive strength,capillary water uptake,water vapor permeability and weather resistance tests.The SEM,EDX,TEM,SAED and XRD results showed that the produced hydroxyapatite could reunite the weathered stone blocks and provide sufficient reinforcement to hold them together.The results of the various tests indicated that the compressive strength and weather resistance of the treated samples was improved significantly.In addition,because of the porous nature of apatite,the water vapor permeability of the treated stone was not affected and its breathability was maintained. | YANG FuWei LIU Yan ZHU YuanCheng LONG ShiJia ZUO GuoFang WANG ChangQing GUO Feng ZHANG BingJian JIANG SiWei | 2012 | Chinese Science Bulletin2012,57,17: | 1 |
| 13 | Hot Deformation Characteristics for a Nickel-base Superalloy GH742y显示文摘The hot deformation characteristics of as-cast nickel-base superalloy GH742y after hot isostatic pressing (HIP)(hereafter referred to as-cast alloy) have been investigated by hot compression tests in the temperature range of 1050 to 1140℃, strain rate range of 0.01 s-1 to 10 s-1 and strain range of 35% to 50% by means of Gleeble-3500 thermal mechanical simulator. The results show that the as-cast alloy exhibits the poor deformability,and shows wedge-shaped cracking beyond the strain of 35%. At strain rates less than 1.0 s-1, the stress-strain curves exhibit nearly steady-state behavior, while at strain rate of 10 s-1, a yield drop and serrated yielding occur. The activation energy values developed on the basis of the experimental data are divided into three domains. The first domain appears at lower strain rate (≤1.0 s-1) and lower temperature (≤1080℃), with the lowest mean value of activation energy about 261.4 kJ/mol. The second domain appears at the same strain rate as the first domain, but higher temperature (>1080℃), with the intermediate mean value of activation energy about 328.8 kJ/mol. The third domain appears at higher strain rate (10 s-1) and temperature range of 1050 to 1140℃, with the largest mean value of activation energy about 605.05 kJ/mol. Three different constitutive equations are established in corresponding to domains. Microstructural observations in the third domain reveal non-uniform dynamic recrystallization (DRX) of homogeneous γ phase, which leads to the poor deformability and the highest Q value. In contrast, microstructures in the first domain show fully DRX of homogeneous γ phase, leading to the better deformability and the lowest Q value. It is noted that the grain size increases with the increment of strain rate or temperature. These results suggest that bulk metal working of this material may be carried out in the first domain where fully DRX of γ homogeneous occurred. | Fuwei Kang Jianfei Sun Guoqing Zhang Zhou Li | 2009 | Journal of Materials Science & Technology2009,25,3: | 1 |
