| 1 | Trajectory planning and yaw rate tracking control for lane changing of intelligent vehicle on curved road显示文摘The lateral control for lane changing of intelligent vehicle on curved road in automatic highway systems was studied. Based on trapezoidal acceleration profile, considering the curvature difference between starting lane and target lane, a new virtual trajectory planning method for lane changing on curved road was presented, and the calculating formulas for ideal states of vehicle in the inertial coordinate system during a lane changing maneuver were established. Applying the predetermined trajectory, the reference yaw angle and yaw rate for lane changing were generated. On the assumption that the information on yaw rate of vehicle can be measured with on-board sensors and based on the lateral dynamical model of vehicle, the yaw-rate-tracking control law was designed by applying nonsingular terminal sliding mode technology. Based on Lyapunov function method, the finite-time convergence property of the system was obtained from the phase-plane analysis. Simulation results showed that if the curvature difference between starting lane and target lane was not considered, then at the finishing time of lane changing, it was impossible to avoid the deviation of the virtual trajectory panned from the target lane, which increased with the decrease of curvature radius. With the trajectory planning method and yaw rate-tracking control law proposed in this paper and considering the curvature difference between the starting lane and target lane, the desired virtual trajectory for lane changing without deviation was obtained and the expected tracking performance was also verified by the simulation. | REN DianBo ZHANG JiYe ZHANG JingMing CUI ShengMin | 2011 | Science China(Technological Sciences)2011，54，3： | 25 |
| 2 | Photocatalytic degradation of phenanthrene on soil surfaces in the presence of nanometer anatase TiO_2 under UV-light显示文摘The effect of nanometer anatase TiO2 was investigated on the photocatalytic degradation of phenanthrene on soil surfaces under a variety of conditions.After being spiked with phenanthrene,soil samples loaded with different amounts of TiO2(0wt.%,1wt.%,2wt.%,3wt.%,and 4 wt.%) were exposed to UV-light irradiation for 25 hr.The results indicated that the photocatalytic degradation of phenanthrene followed the pseudo first-order kinetics.TiO2 significantly accelerated the degradation of phenanthrene with the half-life reduced from 45.90 to 31.36hr for TiO2 loading of 0wt.% and 4wt.%,respectively.In addition,the effects of H2O2,light intensity and humic acid on the degradation of phenanthrene were investigated.The degradation of phenanthrene increased with the concentration of H2O2,light intensity and the concentration of humic acids.It has been demonstrated that the photocatalytic method in the presence of nanometer anatase TiO2 was a very promising technology for the treatments of soil polluted with organic substances in the future. | Jiali Gu Dianbo Dong Lingxue Kong Yong Zheng Xiaojun Li | 2012 | Journal of Environmental Sciences2012，24，12： | 5 |
| 3 | Pseudo-capacitance of ruthenium oxide/carbon black composites for electrochemical capacitors显示文摘Hydrous ruthenium oxide was formed by a new process. The precursor was obtained by mixing the aqueous solutions of RuCl3·xH2O and NaHCO3. The addition of NaHCO3 led to the formation of an oxide with extremely fine RuO2 particles forming a porous network structure in the oxide electrode. Polyethylene glycol was added as a controller to partly inhibit the sol-gel reaction. The rate capacitance of 530 F·g-1 was measured for the powder formed at an optimal annealing temperature of 210°C. Several details concerning this new material, including crystal structure, particle size as a function of temperature, and electrochemical properties, were also reported. In addition, the rate capacitance of the composite electrode reached 800 F·g-1 after carbon black was added. By using the modified electrode of a RuO2/carbon black composite electrode, the electrochemical capacitor exhibits high energy density and stable power characteristics. The values of specific energy and maximum specific power of 24 Wh·kg-1 and 4 kW·kg-1, respec-tively, are demonstrated for a cell voltage between 0 and 1 V. | Xiaofeng Wang Dianbo Ruan Peng Wang Yiqiang Lu | 2008 | Journal of University of Science and Technology Beijing2008，15，6： | 3 |
| 4 | Photolysis of polycyclic aromatic hydrocarbons on soil surfaces under UV irradiation显示文摘Photolysis of some polycyclic aromatic hydrocarbons (PAHs) on soil surfaces may play an important role in the fate of PAHs in the environment.Photolysis of PAHs on soil surfaces under UV irradiation was investigated.The effects of oxygen,irradiation intensity and soil moisture on the degradation of the three PAHs were observed.The results showed that oxygen,soil moisture and irradiation intensity enhanced the photolysis of the three PAHs on soil surfaces.The degradation of the three PAHs on soil surfaces is related to their absorption spectra and the oxidation-half-wave potential.The photolysis of PAHs on soil surfaces in the presence of oxygen followed pseudo first-order kinetics.The photolysis half-lives ranged from 37.87 days for benzo[a]pyrene to 58.73 days for phenanthrene.The results indicate that photolysis is a successful way to remediate PAHs-contaminated soils. | Chengbin Xu Dianbo Dong Xuelian Meng Xin Su Xu Zheng Yaoyao Li | 2013 | Journal of Environmental Sciences2013，25，3： | 2 |

| 10 | Temperature Compensation Algorithm for Hydraulic System Pressure Control显示文摘In this paper the control mechanism of solenoid valve is analyzed,which shows the solenoid valve control is actually the control of coil current.The response characteristic of coil current is related to coil inductance and resistance.The coil resistance is influenced greatly by the ambient temperature and the self-heating of coil,which affects the control precision of coil current.First,considering the heat dissipation mode of coil,the coil temperature model is established from the perspective of heat conduction,and a temperature compensation algorithm for hydraulic system pressure control is put forward.Then the hardware-in-the-loop testbed is set up by using the dSPACE platform,carrying out wheel cylinder pressurization tests with inlet valve fully opened at-40℃ and 20℃,and testing the actual pressure of wheel cylinder with the target pressures at-40℃ and 6 000 kPa/s(pressurization rate).The results show that the pressure control temperature compensation algorithm proposed in this paper accurately corrects the influence of resistance temperature drift on the response accuracy of wheel cylinder pressure.After the correction,the pressure difference is less than 500 kPa,which can meet the control accuracy requirements of solenoid valve,enriching the linear control characteristic of solenoid valve. | Huien Gao Liang Chu Jianhua Guo Dianbo Zhang | 2018 | Journal of Beijing Institute of Technology2018，27，4： | 1 |

| 16 | Experimental investigation on oil-gas separator of air-conditioning systems显示文摘The oil-return system plays an important role in the variable refrigerant flow (VRP) systems because it ensures the reliable operation of the VRF systems. The oil-gas separator is the most essential component of the oil- return system, and the separation efficiency of the separator directly influences the performance of the VRF systems. Therefore, in this paper, a test rig was built to measure the oil discharge ratio of the compressor and the separation efficiency of the oil-gas separator. A sound velocity transducer was used to measure the oil mass concentration instantaneously, because the sound velocity was changed with the mass ratio of oil to refrigerant. The separation efficiency of the separator could be obtained by comparing the mass fraction of oil to refrigerant before and after the separator was connected to the system. | Dianbo XIN Shuliang HUANG Song YIN Yuping DENG Wenqiang ZHANG | 2019 | Frontiers in Energy2019，13，2： | 1 |

| 18 | A Serum Biomarker Model to Diagnose Pancreatic Cancer Using Proteomic Fingerprint Technology显示文摘OBJECTIVE To establish a serum protein pattern model for screening pancreatic cancer. METHODS Twenty-nine serum samples from patients with pancreatic cancer were collected before surgery,and an additional 57 serum samples from age and sex-matched individuals without cancer were used as controls.WCX magnetic beans and a PBS Ⅱ-C protein chip reader (Ciphergen Biosystems Inc) were employed to detect the protein fingerprint expression of all serum samples. The resulting profiles comparing serum from cancer and normal patients were analyzed with the Biomarker Wizard system,to establish a model using the Biomarker Pattern system software. A double-blind test was used to determine the sensitivity and specificity of the model. RESULTS A group of 4 biomarkers(relative molecular weights were 5,705 Da,4,935 Da,5,318 Da,3,243 Da) were selected to set up a decision tree to produce the classification model to effectively screen pancreatic cancer patients.The results yielded a sensitivity of 100%(20/20),specificity of 97.4% (37/38).The ROC curve was 99.7%.A double-blind test used to challenge the model resulted in a sensitivity of 88.9% and a specificity of 89.5%. CONCLUSION New serum biomarkers of pancreatic cancer have been identified.The pa ern of combined markers provides a powerful and reliable diagnostic method for pancreatic cancer with high sensitivity and specificity. | Chunlin Ge Ning Ma Dianbo Yao Fengming Luan Chaojun Hu Yongzhe Li Yongfeng Liu | 2008 | Chinese Journal of Clinical Oncology2008，5，3： | 0 |
| 19 | Reference Modelof Desired Yaw Anglefor Automated Lane Changing Behavior of Vehicle显示文摘In this paper,it studies the problem of trajectory planning and tracking for lane changing behavior of vehicle in automatic highway systems. Based on the model of yaw angle acceleration with positive and negative trapezoid constraint,by analyzing the variation laws of yaw motion of vehicle during a lane changing maneuver,the reference model of desired yaw angle and yaw rate for lane changing is generated. According to the yaw angle model,the vertical and horizontal coordinates of trajectory for vehicle lane change are calculated. Assuming that the road curvature is a constant,the difference and associations between two scenarios are analyzed,the lane changing maneuvers occurred on curve road and straight road,respectively. On this basis,it deduces the calculation method of desired yaw angle for lane changing on circular road. Simulation result shows that,it is different from traditional lateral acceleration planning method with the trapezoid constraint,by applying the trapezoidal yaw acceleration reference model proposed in this paper, the resulting expected yaw angular acceleration is continuous,and the step tracking for steering angle is not needed to implement. Due to the desired yaw model is direct designed based on the variation laws of raw movement of vehicle during a lane changing maneuver, rather than indirectly calculated from the trajectory model for lane changing, the calculation steps are simplified. | Dianbo Ren Guanzhe Zhang Hangzhe Wu | 2016 | Journal of Harbin Institute of Technology(New Series)2016，23，1： | 0 |
| 20 | Study on the effects of carbon coating on lithium-storage kinetics for soft carbon显示文摘Carbon-coating is a simple and practical method to improve the electrochemical performance of soft carbon anode for fast-charging lithium-ion battery,e.g.,reducing the loss of active lithium during the formation of the solid electrolyte interface(SEI)film,and thereby improving the initial coulombic efficiency.However,the systematic study of relationships between carbon-coating layer properties and electrochemical performances is still lacking.Therefore,two soft carbon materials with different carbon-coating layers were used as model materials,which were prepared by vapor-phase method and solid-phase method,respectively.SEM,TEM,XRD and Raman were conducted to characterize the structural evolution of the soft carbon in the coating process.CV,GCPL,EIS and GITT were conducted to analyze the electrochemical performance of carbon-coating soft carbon.This work provides a good guidance for the development of fast-charging soft carbon material. | MENG Fanju ZHANG Xi QIAO Zhijun YANG Bin YU Miao WANG Yuzuo RUAN Dianbo | 2022 | 储能科学与技术2022，11，11： | 0 |
