| 1 | Experimental study on the mechanical properties of rocks at high temperature显示文摘The mechanical properties of marble, limestone, and sandstone as well as the stress-strain curve, the varying characteristics of the peak strength, the peak strain and elastic modulus were studied by using the MTS810 Rock Mechanics Servo-controlled Testing System under the action of temperatures rang- ing from room temperature to 800℃ . Results show that (1) the peak strength and elastic modulus of marble fluctuate at the temperature from normal to 400 ℃ ; and they decrease gradually over 400℃ . (2) With the rise of the temperature, the peak strength and elastic modulus of limestone show downward trend from normal temperature to 200 ℃ ; have little change from 200 ℃ to 600 ℃; and decrease sharply over 600 ℃ . (3) The peak strength of sandstone shows a downward trend while a little change for elastic modulus at normal temperature to 200 ℃ ; and from 200 ℃ to 600 ℃ , the peak strength of sandstone in- creases while a little change for elastic modulus; the peak strength and elastic modulus decrease rap- idly at the temperature over 600 ℃ . (4) The peak strain of limestone shows little change at normal tem- perature to 600 ℃ , however, the peak strain increases rapidly over 600 ℃; and for marble and sandstone, the peak strain decreases with the rise of the temperature from normal temperature to 200℃ , the peak strain increases rapidly over 200℃. The result can provide valuable references for the rock engineering design at high temperature. | ZHANG LianYing MAO XianBiao LU AiHong | 2009 | Science China(Technological Sciences)2009，52，3： | 30 |
| 2 | Effect of specimen size on energy dissipation characteristics of red sandstone under high strain rate显示文摘In this experiment, red sandstone specimens, having slenderness ratios of 0.5, 0.7, 0.9 and 1.1 respectively, were subjected to blow tests using a Split Hopkinson Pressure Bar(SHPB) system at a pressure of 0.4 atmospheres. In this paper, we have analyzed the effect of slenderness ratio on the mechanical properties and energy dissipation characteristics of red sandstone under high strain rates. The processes of compaction, elastic deformation and stress softening deformation of specimens contract with an increase in slenderness ratio, whilst the nonlinear deformation process extends correspondingly. In addition, degrees of damage of specimens reduced gradually and the type of destruction showed a transformation trend from stretching failure towards shear failure when the slenderness ratio increased. A model of dynamic damage evolution in red sandstone was established and the parameters of the constitutive model at different ratios of length to diameter were determined. By comparison with the experimental curve, the accuracy of the model, which could reflect the stress–strain dynamic characteristics of red sandstone, was verified. From the view of energy dissipation, an increase in slenderness ratio of a specimen decreased the proportion of energy dissipation and caused a gradual fall in the capability of energy dissipation during the specimen failure process. To some extent, the study indicated the effects of slenderness ratios on the mechanical properties and energy dissipation characteristics of red sandstone under the high strain rate, which provides valuable references to related engineering designs and academic researches. | Li Ming Mao Xianbiao Lu Aihong Tao Jing Zhang Guanghui Zhang Lianying Li Chong | 2014 | International Journal of Mining Science and Technology2014，24，2： | 24 |

| 4 | Effects of strain rates on mechanical properties of limestone under high temperature显示文摘The experimental tests for limestone specimens at 700 °C in uniaxial compression were carried out to inves- tigate the mechanical effects of loading rates on limestone by using a MTS810 rock mechanics servo- controlled testing system considering the loading rate as a variable. The mechanical properties of limestone such as the stress-strain curve, variable characteristics of peak strength and the modulus of elasticity of limestone were studied under the strain rates ranging from 1.1 10à5 to 1.1 10à1 sà1. (1) Sharp decreases were shown for the peak strength and elastic modulus of limestone from 1.1 10à5 to 1.1 10à4 sà1 at 700 °C as well as a downward trend was shown from 1.1 10à4 to 1.1 10à1 sà1 with the rise of the strain rate. (2) The peak strain increased from 1.1 10à5 to 1.1 10à4 sà1, however, there was no obvious changes shown for the peak strain of limestone from 1.1 10à4 to 1.1 10à1 sà1. These results can provide valuable references for the rock blasting effect and design of mine. | Tang Furong Mao Xianbiao Zhang Lianying Yin Huiguang Li Yan | 2011 | Mining Science and Technology2011，21，6： | 10 |
| 5 | Effect of loading rates on the characteristics of thermal damage for mudstone under different temperatures显示文摘The uniaxial compression tests for mudstone specimens are carried out with four different loading rates from room temperature to 400℃ by using the Rock Mechanics Servo-controlled Testing System MTS810 and high temperature furnace MTS652.02.The mechanical properties of mudstone with various loading rates are studied under different temperature conditions.The results show that when temperature increases from room temperature to 400℃ and loading rate is less than 0.03 mm/s,the peak strength of mudstone specimen decreases as loading rate increases,while the various peak strengths show significant differences when loading rate exceeds 0.03 mm/s.At room temperature,the elastic modulus decreases at the first time and then increases with loading rate rising.When the temperature is between200 and 400℃,the elastic modulus presents a decreasing trend with increasing loading rate.With increasing the loading rate,the number of fragments in mudstone becomes larger and even the powder is observed in mudstone with higher loading rate.Under high loading rate,the failure mode of mudstone specimens under different temperatures is mainly conical damage. | Mao Rongrong Mao Xianbiao Zhang Lianying Liu Ruixue | 2015 | International Journal of Mining Science and Technology2015，25，5： | 7 |

| 8 | Macroscopic and microscopic fracture features of concrete used in coal mine under chlorine salt erosion显示文摘The microscopic morphology and pore structure characteristics of concrete with composite admixtures(fly ash and mineral powder) after chlorine salt erosion were analyzed via scanning electron microscopy(SEM) and mercury injection porosimetry(MIP), providing the basis for the design and maintenance of concrete shafts in coal mines. The above-mentioned characteristics were compared with the macroscopic characteristic of concrete fractures under uniaxial compression. The results show that the macroscopic fracture characteristics of concrete under uniaxial compression change from longitudinal split fracture and oblique section shear fracture to conjugate cant fracture, and the degree of breakage increases.Interface cracks, cement paste cracks, spherical surface cracks, and aggregate cracks appear in concrete under uniaxial compression. In the early stages of corrosion, the original cracks which are obvious are repaired. When the corrosion becomes more serious, cement paste cracks appear, and the number of harmful holes increases while the number of harmless holes decreases. This study also reveals the relationship between the macroscopic properties and microscopic structure of concrete under chloride salt erosion. Finally, the paper preliminarily discussed the relationship between the macroscopic properties and mesoscopic characteristics of concrete under chlorine salt erosion. | Li Bing Yin Huiguang Mao Xianbiao Li Yan Zhang Lianying Liu Ruixue Qiu Peitao | 2016 | International Journal of Mining Science and Technology2016，26，3： | 4 |
| 9 | Neural plasticity after spinal cord injury显示文摘Plasticity changes of uninjured nerves can result in a novel neural circuit after spinal cord injury, which can restore sensory and motor functions to different degrees. Although processes of neural plasticity have been studied, the mechanism and treatment to effectively improve neural plasticity changes remain controversial. The present study reviewed studies regarding plasticity of the central nervous system and methods for promoting plasticity to improve repair of injured central nerves. The results showed that synaptic reorganization, axonal sprouting, and neurogenesis are critical factors for neural circuit reconstruction. Directed functional exercise, neurotrophic factor and transplantation of nerve-derived and non-nerve-derived tissues and cells can effectively ameliorate functional disturbances caused by spinal cord injury and improve quality of life for patients. | Jian Liu Xiaoyu Yang Lianying Jiang Chunxin Wang Maoguang Yang | 2012 | Neural Regeneration Research2012，7，5： | 4 |
| 10 | Exchange-Biased NiFe_(2)O_(4)/NiO Nanocomposites Derived from NiFe-Layered Double Hydroxides as a Single Precursor显示文摘NiFe_(2)O_(4) nanoparticles(<10 nm)embedded in a NiO matrix have been fabricated by calcining the corresponding Ni^(Ⅱ)Fe^(Ⅲ)-layered double hydroxide(LDH)precursors at high temperature(500℃).Compared with the NiFe_(2)O_(4)/NiO nanocomposite obtained by calcination of a precursor prepared by a traditional chemical coprecipitation method,those derived from NiFe-LDH precursors show much higher blocking temperatures(TB)(~380 K).The enhanced magnetic stability can be ascribed to the much stronger interfacial interaction between NiFe_(2)O_(4) and NiO phases due to the topotactic nature of the transformation of the LDH precursor to the NiFe_(2)O_(4)/NiO composite material.Through tuning the Ni^(Ⅱ)/Fe^(Ⅲ) molar ratio of the NiFe-LDH precursor,the NiFe_(2)O_(4) concentration can be precisely controlled,and the TB value as well as the magnetic properties of the final material can also be regulated.This work represents a successful example of the fabrication of ferro(ferri)magnetic(FM)/antiferrimagnetic(AFM)systems with high magnetic stability from LDH precursors.This method is general and may be readily extended to other FM/AFM systems due to the wide range of available LDH precursors. | Xiaofei Zhao Sailong Xu Lianying Wang Xue Duan Fazhi Zhang | 2010 | Nano Research2010，3，3： | 4 |
| 11 | Land cover changes and the effects of cultivation on soil properties in Shelihu wetland,Horqin Sandy Land,Northern China显示文摘Land cover change plays an essential role in the alternation of soils properties.By field investigation and applying satellite images,land cover information in the Shelihu wetland was carried out in an area of 2,819 hm 2 in 1985,1995,2000,2005,2010 and 2011,respectively,in Horqin Sandy Land.A total of 57 soil sampling sites across Shelihu were chosen in wet meadow(CL0),cropland(CL) and sandy land(SL) according to the spatial characteristics of water body change.Soil texture,organic carbon(SOC),total nitrogen(TN) and total phosphorus(TP) contents,electrical conductivity(EC) and pH were measured at the soil depths of 0-10,10-20 and 20-40 cm to examine the influence of agricultural conversion and continuous cultivation on soil properties.The results showed that the study area was covered by water body in 1985,which gradually declined afterwards and then reclaimed rapidly at a mean annual rate of 132.1 hm 2 /a from wet meadow to cropland since 1995.In 2011,water body was drained and the area was occupied by 10.8% of CL0,76.9% of CL and 12.3% of SL.Large amounts of SOC,TN and TP were accumulated in the above depths in CL0.Soil in CL0 also had higher EC and silt and clay fractions,lower pH than in SL and CL.Soil in SL was seriously degraded with lower contents of SOC,TN and TP than in CL and CL0.SOC,TN content and EC in CL decreased with the increase of cultivation age,while pH showed a reverse trend with significance at plough horizon.The agricultural conversion in Shelihu was driven by the comprehensive factors of precipitation reduction,economic development and intense competitions for irrigation water.Continuous cultivation in this process is not sustainable because of SOC degradation and nutrient content reduction.The key point is that conventional tillage and removal of residuals induced further land degradation.Wetland reclamation for immediate economic interests led to greater costs in the long-term environmental restoration in Horqin Sandy Land. | Jie LIANI XueYong ZHAO XiaoAn ZUO ShaoKun WANG XinYuan WANG YongQing LUO | 2013 | Journal of Arid Land2013，5，1： | 4 |

| 13 | Meso-structure and fracture mechanism of mudstone at high temperature显示文摘The meso-structure mineral composition and fracture mechanism of uniaxial compressed mudstone samples at high temperature were analyzed by XRD and scanning electron microscopy. The effect of temperature on mudstone composition and fracture mechanism were studied from a meso-structural perspective, and the relationship between meso-structure and macro-mechanical characteristics at high temperature was revealed. The findings demonstrated that the fluctuation in diffraction intensity of kaolinite in the mudstone caused the fluctuation in its mechanical properties. The overall structure underwent a phase change around 600 ℃, which led to the sudden change in the mechanical properties of mudstone samples. When the temperature reached 600 ℃, the crystalline state worsened and kaolinite disappeared; however, some illite was produced, indicating that the chemical reaction of the structure and sudden drop of bearing capacity of the mudstone. Mudstone fracturing at high temperature involves mainly intergranular and transgranular fractures, which are typical in micro-brittle tensile failure. Considering the macro-fracture characteristics of mudstone, the results suggested that macro-fracture under external force corresponds to the meso-fracture. | Zhang Lianying Mao Xianbiao Liu Ruixueab Li Yan Yin Huiguang | 2014 | International Journal of Mining Science and Technology2014，24，4： | 3 |
| 14 | Application of Piezoelectric Actuator and Compliant Structures to Achieve Flapping Wing Motion for a MAV显示文摘Micro Aerial Vehicles(MAVs) are the smallest artificial aircraft.Most of the flapping wings MAVs are powered by electric motors of various capacities.We report in this paper the application of piezoelectric actuators as power system for a flapping wing MAV using a compliant displacement amplification mechanism.The actuator used for this application is a pre-stressed cut piece of TH-7R type Thunder actuator.A two-bar compliant mechanism with two flexures has been developed to convert the linear displacement into angular movement and amplification.The specimens were made from carbon fiber links and nylon flexures.We also proposed to use the product of frequency(F) and tip displacement(D), F * D as a criteria for the characterization of an amplifying mechanism.The best specimen according to this criterion is obtained for a 5mm length flexure specimen made of three layers of nylon.The F*D value obtained for this specimen was(0.58) Hz.m.ANSYS finite element analysis results for different flexural thickness and lengths were obtained and have been compared to the experimental results.The effect of both the thickness and length of the flexure on a particular arrangement has been discussed. | Kranti.

| 15 | The green hydrolysis technology of hemicellulose in corncob by the repeated use of hydrolysate显示文摘To achieve green hydrolysis technology of hemicellulose through repeated using hydrolysate,the hydrolysis of hemicellulose in corncob was studied.The influence of repeated use of corncob hydrolysate on concentrations of D-xylose and L-arabinose was investigated.The loss rates of D-xylose in the prepared D-xylose solutions both with and without corncob,and repeated using corncob hydrolysate under identical acidity condition were discussed.The result shows that D-xylose concentration and L-arabinose concentration are all gradually increasing with the growing time of repeated use of corncob hydrolysate.After the fifth repetition,the concentrations of D-xylose and L-arabinose are 196.7 g·L^(-1)and 22.0 g·L^(-1),respectively.Substance inhibiting the degradation of D-xylose is generated during repeated use of corncob hydrolysate,and the production is further proved by the change of D-xylose concentration and the loss rate of D-xylose over heating time. | Lei Guo Yangdong Hu Lianying Wu Chen Liang Weitao Zhang | 2018 | Chinese Journal of Chemical Engineering2018，26，1： | 2 |
| 16 | A new model in correlating and calculating the solid–liquid equilibrium of salt–water systems显示文摘In this work, a new activity coefficient model was deduced for the correlation of solid–liquid equilibrium(SLE) in electrolyte solutions. The new excess Gibbs energy equation for SLE contains two parts: the single electrolyte item and the mixed electrolyte item. Then a new hypothesis for the reference state of activity coefficients was proposed in the work. Literature data for single electrolyte solution and mixed electrolyte solution systems,with temperature spanning from 273.15 to 373.15 K, were successfully correlated using the developed model. | Xianzhen Xu Yangdong Hu Lianying Wu Xia Chen | 2016 | Chinese Journal of Chemical Engineering2016，24，8： | 2 |
