| 1 | Influence of oxygen gas content on the structural and optical properties of ZnO thin films deposited by RF magnetron sputtering at room temperature显示文摘Zinc oxide (ZnO) thin films were deposited on sapphire (0001) substrates at room temperature by radiofrequency (RF) magnetron sputtering at oxygen gas contents of 0%,25%,50% and 75%,respectively.The influence of oxygen gas content on the structural and optical properties of ZnO thin films was studied by a surface profile measuring system,X-ray diffraction analysis,atomic force microscopy,and UV spectrophotometry.It is found that the size of ZnO crystalline grains increases first and then decreases with the increase of oxygen gas content,and the maximum grain size locates at the 25% oxygen gas content.The crystalline quality and average optical transmittance (>90%) in the visible-light region of the ZnO film prepared at an oxygen gas content of 25% are better than those of ZnO films at the other contents.The obtained results can be attributed to the resputtering by energetic oxygen anions in the growing process. | LIU Baoting ZHOU Yang ZHENG Hongfang LI Mana GUO Zhe HAO Qingxun PENG Yingcai | 2011 | Rare Metals2011，30，2： | 6 |
| 2 | Analysis on Lean Blowout of Swirl Cup Combustor at Atmospheric Pressure Condition显示文摘The experimental data of lean blowout fuel/air ratio of a rectangular swirl cup combustor with different inlet temperatures was obtained at atmospheric pressure condition.Numerical simulations both burning and non-burning were performed corresponding to the experimental data at lean blowout.Results indicated that the size of the recirculation region in the primary zone was obviously smaller when burning than non-burning,but the locations of the cores of their recirculation regions were almost the same.The increase of inlet air temperature didn't mean the rise of the temperature of recirculation region core.The location of the maximum temperature in the primary zone was not the same as that one of the core temperature of the recirculation region.Further more,the reasons were analyzed how the lean blowout fuel/air ratio changed with the inlet temperature increasing under the actions of factors both positive and negative to combustion,and this would be helpful to deepen the understanding of the lean blowout process of swirl cup combustor. | Yixiang Yuan Hailin Fan Xiyang Liu Qi Dong Chunqing Tan Baoting Guo | 2011 | Journal of Thermal Science2011，20，4： | 2 |

| 4 | General Design and Thermodynamic Analysis of a Supercritical Carbon Dioxide Cannon显示文摘This paper presents a new supercritical carbon dioxide(SCO_(2))cannon based on the carbon dioxide(CO_(2))’s thermodynamic cycle under constant volume.First,Virial equation and NIST database are applied to formulate SCO_(2)’s property and analyze the thermodynamic cycle,which is aimed to get the optimization equation using the cannon’s exit velocity as objective function.Then the cannon’s structural parameters,such as diaphragm thickness and barrel length,and CO_(2)’s filling mass,are optimized.Finally,the flow field and velocity’s change during the launch process is performed with FLUENT.In field test,the ultra-high pressure sensor and ultra-high speed camera are used to measure the pressure distribution along the barrel’s axial direction and the projectile’s exit velocity under different conditions.The results show that all the performance indexes meet the design requirement.The innovative SCO_(2)cannon in this paper has obvious advantages such as high safety,low cost and fast loading,which can be applied in many situations such as disaster relief,peacekeeping and anti-terrorism.Moreover,the unique energy storage method and thermodynamic design ensure its subsequent development. | ZHANG Fan LIU Hongrui WU You LI Jiaqi YU Huazhang WANG Xiaoliang GUO Baoting YUAN Yixiang | 2021 | Journal of Thermal Science2021，30，1： | 1 |
