| 1 | Characteristics of gas-solid micro fluidized beds for thermochemical reaction analysis显示文摘Fuel conversion and clean energy reaction systems involve a variety of catalytic and non-catalytic gas-solid thermochemical reactions.A good understanding of the correct reaction mechanism and kinetics,as well as the profiles of reaction products,is of great significance to the development,design,and operation of such reaction systems.The micro fluidized bed reaction analysis provides an efficient and reliable method to acquire this essential information with low capital and operating costs,low energy consumption and enhanced safety.This paper provides an overview of the system and its characteristics for the micro fluidized bed reaction analyzer that has been well proven to be a reliable new approach as well as an instrument for characterizing various gas-solid thermochemical reactions. | Zhennan Han Junrong Yue Xi Zeng Jian Yu Fang Wang Shaozeng Sun Hong Yao Guangqian Luo Xuejing Liu Yining Sun Fu Ding Liangliang Fu Lei Shi Kangjun Wang Jiebin Yang Shaonan Wang Xueqing Chen Dingrong Bai Guangwen Xu | 2020 | Carbon Resources Conversion2020，3，1： | 6 |
| 2 | Differential Coherent Algorithm Based on Fast Navigation-Bit Correction for Airborne GNSS-R Software Receivers显示文摘Signals from the Global Navigation Satellite System (GNSS) scatter over the sea surface resulting in relatively low Signal-to-Noise Ratios (SNR). A differential coherent algorithm is given here to improve the SNR and reduce the performance degradation due to the Squaring-Loss and the navigation-bit effect. The algorithm uses fast navigation-bit correction for Delay-Doppler Maps (DDM) in airborne Global Navigation Satellite Signal Reflectometry (GNSS-R) software receivers. The system model is introduced with an analysis of the statistical properties with simulations to support the theoretical analysis. Field experiments with real airborne receivers then demonstrate the effectiveness of this algorithm. Comparisons with test results show that this algorithm offers a significant SNR gain over conventional algorithms. | Yiran Wang Bo Zhang Dingrong Shao | 2013 | Tsinghua Science and Technology2013，18，1： | 3 |
| 3 | A General Pairwise Key Predistribution Scheme for Wireless Sensor Networks显示文摘This paper develops a general hypercube-based key predistribution scheme for establishing pairwise keys between sensor nodes using polynomials, which is parameterized by the dimension of hypercube and the Hamming distance threshold variables. The scheme addresses the weaknesses of existing key predistribution schemes, which have either worse security or lower efficiency. It exhibits a nice property—when the Hamming distance between any two neighboring sensor nodes is less than the predefined threshold, the pairwise key can be established directly. Extensive performance and security analysis shows that by increasing Hamming distance threshold value, we can trade off the resilience against node capture attack for higher probability of direct pairwise key establishment, so as to save the energy consumption which is the most important issue for sensor networks. | DING Xiaoyu LIU Zhiping SHAO Dingrong | 2008 | Wuhan University Journal of Natural Sciences2008，13，6： | 2 |
| 4 | Screening of Anti-tumor Effective Extracts from Sedum bulbiferum Makino and HPLC Determination of Quercetin and Kaempferol in This Herbal Medicine显示文摘[Objectives] To investigate the anti-tumor activity of Sedum bulbiferum Makino in vitro,and establish a HPLC method for determination of quercetin and kaempferol in S. bulbiferum. [Methods] The inhibitory activities of different extracts and total flavonoids of S. bulbiferum on proliferation of three kinds of cancer cells( Hep G2,EC109,SW480) were tested by MTT assay. HPLC method for determination of quercetin and kaempferol in S. bulbiferum was established. [Results]The growth and proliferation of the three kinds of cancer cells were all significantly inhibited by ethyl acetate fraction and total flavonoids isolated from S. bulbiferum. With each extraction concentration increasing,stronger anti-tumor activity was found. The linear ranges of quercetin and kaempferol were 0. 03-0. 36 μg( R = 0. 999 9) and0. 08-0. 96 μg( R = 0. 999 9),and the average recoveries were 98. 90%( RSD = 1. 15%) and 98. 27%( RSD = 1. 70%),respectively.[Conclusions]S. bulbiferum has significant anti-tumor activity in vitro. The HPLC method established was accurate,reproducible,and could be used for quality control of this crude drug. | Liming MENG Xiangluan WAN Luyang LI Jing HU Pu CHEN Dingrong WAN | 2019 | Medicinal Plant2019，10，3： | 2 |

| 13 | Analysis and Prediction of Corrosion Risk in Atmospheric Distillation Tower Overhead System显示文摘In order to optimize the atmospheric tower overhead low-temperature system,the physical parameters,multiphase composition,aqueous dew point temperature,and ammonium salt crystallization temperature are simulated with process simulation software.The temperature distribution in overhead heat exchanger is calculated by heat transfer calculation.The special parts with elbows near the inlet and outlet of heat exchanger are studied by fluid field analysis.Results indicate that under current operating conditions,the aqueous dew point temperature and initial crystallization temperature of NH4Cl are 91°C and 128°C,respectively.Ammonium salt appears in the distillation tower and liquid water occurs in heat exchanger tubes,in which the dew point induced corrosion is the most direct factor for heat exchanger corrosion.In the heat exchanger,condensate water appearing in the area 2.7 meters away from the bundle inlet can give rise to corrosion risk under the moist NH4Cl and high concentration of acidic solution circumstance.For the pipes and elbows located near the inlet and the outlet of heat exchanger,the flow field presents an unsymmetrical distribution.High risk areas are mainly concentrated on the external bend of elbows where the liquid water concentration is higher.The coupling of simulation methods established thereby is approved as an effective way to evaluate the corrosion risk in the atmospheric column overhead system and can provide a scientific basis for corrosion control. | Niu Luna Han Lei Chen Wenwu Pan Long Zhang Yanling Qu Dingrong | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，1： | 1 |
