| 1 | Experimental comparison between aircraft fuel tank inerting processes using NEA and MIG显示文摘Fuel tank inerting technologies are able to reduce the fire risk by injection of inert gas into the ullage or fuel, the former called ullage washing and the latter fuel scrubbing. The Green On-Board Inert Gas Generation System(GOBIGGS) is a novel technology based on flameless catalytic combustion, and owning to its simple structure and high inerting efficiency, it has received a lot of attentions. The inert gas in the GOBIGGS is mainly comprised of CO_2, N_2, and O_2(hereinafter, Mixed Inert Gas(MIG)), while that in the On-Board Inert Gas Generation System(OBIGGS), which is one of the most widely used fuel tank inerting technologies, is NitrogenEnriched Air(NEA). The solubility of CO_2 is nearly 20 times higher than that of N_2 in jet fuels,so the inerting capability and performance are definitely disparate if the inert gas is selected as NEA or MIG. An inerting test bench was constructed to compare the inerting capabilities between NEA and MIG. Experimental results reveal that, if ullage washing is adopted, the variations of oxygen concentrations on the ullage and in the fuel are nearly identical no matter the inert gas is NEA or MIG. However, the ullage and dissolved oxygen concentrations of MIG scrubbing are always higher than those of NEA scrubbing. | Lei SHAO Weihua LIU Chaoyue LI Shiyu FENG Chenchen WANG Jun PAN | 2018 | Chinese Journal of Aeronautics2018，31，7： | 11 |

| 5 | Variation in Summer Surface Air Temperature over Northeast Asia and Its Associated Circulation Anomalies显示文摘This study investigates the interannual variation of summer surface air temperature over Northeast Asia(NEA) and its associated circulation anomalies.Two leading modes for the temperature variability over NEA are obtained by EOF analysis.The first EOF mode is characterized by a homogeneous temperature anomaly over NEA and therefore is called the NEA mode.This anomaly extends from southeast of Lake Baikal to Japan,with a central area in Northeast China.The second EOF mode is characterized by a seesaw pattern,showing a contrasting distribution between East Asia(specifically including the Changbai Mountains in Northeast China,Korea,and Japan) and north of this region.This mode is named the East Asia(EA) mode.Both modes contribute equivalently to the temperature variability in EA.The two leading modes are associated with different circulation anomalies.A warm NEA mode is associated with a positive geopotential height anomaly over NEA and thus a weakened upper-tropospheric westerly jet.On the other hand,a warm EA mode is related to a positive height anomaly over EA and a northward displaced jet.In addition,the NEA mode tends to be related to the Eurasian teleconnection pattern,while the EA mode is associated with the East Asia-Pacific/PacificJapan pattern. | Wei CHEN Xiaowei HONG Riyu LU Aifen JIN Shizhu JIN Jae-Cheol NAM Jin-Ho SHIN Tae-Young GOO Baek-Jo KIM | 2016 | Advances in Atmospheric Sciences2016，33，1： | 6 |
| 6 | NEA GaN和GaAs光电阴极激活机理对比研究显示文摘本文结合激活过程中光电流变化规律和成功激活后阴极表面模型,研究了NEA GaN和GaAs光电阴极激活机理的异同。实验表明:NEA GaN激活过程中光电流不象GaAs那样按近似指数规律的包络慢速循环上升,而是在约1min之内就可达到峰值,Cs/O激活时引入O后光电流的增长幅度不大,NEA特性仅在Cs激活时即可获得。GaAs光电阴极激活过程中O的引入是获得NEA特性的必要条件,也是真空能级下降的重要转折点,O引入后光电流幅值有较大幅度的增长。采用双偶极层模型可以解释GaN和GaAs光电阴极Cs/O激活后表面势垒的降低,但偶极层在降低表面势垒的程度方面有较大差异,GaN光电阴极降得更低。 | 乔建良 常本康 牛军 杨智 邹继军 | 2009 | 真空科学与技术学报2009，29，2： | 6 |

| 11 | Quantum efficiency decay mechanism of NEA GaN photocathode: A first-principles research显示文摘Using the first-principles method based on the density functional theory(DFT), the work function of seven different Ga N(0001) e1 × 1T surface models is calculated. The calculation results show that the optimal ratio of Cs to O for activation is between 3∶1 and 4∶1. Then, Cs/O activation and stability testing experiments on reflection-mode negative electron affinity Ga N photocathodes are performed. The surface model [Ga N(Mg): Cs]Cs-O after being activated with cesium and oxygen is used. The experiment results illustrate that the adsorption of O contained in the residual gas increases the surface potential barrier and the reduction of the effective dipole quantity is the basic cause of the quantum efficiency decay. | 沈洋 陈亮 张淑琴 钱芸生 | 2015 | Chinese Optics Letters2015，13，10： | 2 |

| 16 | A STUDY OF THE WINTER-WINTER RECURRENCE MECHANISM OF THE TEMPERATURES IN NORTHERN EAST ASIA显示文摘In this study, the winter-summer-winter seasonal variation characteristics of the atmospheric temperature in northern East Asia(NEA) during the past 60 years are analyzed. The results revealed a type of new seasonal variation mechanism of temperature: winter-winter recurrence(WWR). This study initially discussed the formation mechanism of WWR from the angle of the relationship between the WWR and the atmospheric internal factors and external forcing.The main conclusions are summarized as follows:(1) The winter-summer-winter continuous variation of the AO anomaly index has consistent characteristics with the atmospheric variation of the WWR in the NEA, and their 60-year correlation coefficient reaches 0.43, passing the 95% significance level. It is indicated that the seasonal anomaly of the AO has a certain influence on the WWR;(2) Overall, the PDO maintains a negative phase in the negative WWR years,while it displays the opposite feature in the positive WWR years. The negative(positive) anomaly of PDO is favourable to the occurrence of sustainable low(high) temperatures in the NEA, and may be the important external driving factor for motivating the WWR in the NEA;(3) The binary regression, based on the PDO and AO indexes successfully reproduces the curve of T_(WWR-HG), which is significantly correlated with the WWR index TWWR, and can reproduce the time-height profile of the WWR characteristics from 400 to 1,000 hPa. Therefore, it is concluded that the WWR of the atmospheric temperatures in the NEA is the result of the combined action of the PDO and AO. | 王晓娟 乔少博 封国林 | 2018 | Journal of Tropical Meteorology2018，24，1： | 1 |
