1BAYQIK~——高浓度二氧化硫烟气制酸创新工艺显示文摘介绍拜耳技术服务公司开发的准等温接触高浓度二氧化硫烟气制酸创新工艺BAYQIK。详述该工艺的理论基础、反应器结构、模型建立、中间试验以及在铅冶炼烟气制酸装置中的应用。BAYQIK艺的特点在于采用列管式固定床反应器,传统钒催化剂装在管内,冷却介质在壳程流动。氧化过程放出的热量被连续移走,从而使催化剂始终处于可承受的最高温度以下,即使反应器进气φ(SO2)超过50%。BAYQIK工艺可提供各种经济和工艺优点,包括可降低投资与操作成本,对于新建装置和扩能改造项目同样适用。T.

2Comparison of hepatic venous pressure gradient and endoscopic grading of esophageal varices显示文摘AIM: To determine the correlation between the hepatic venous pressure gradient and the endoscopic grade of esophageal varices.METHODS: From September 2009 to March 2013, a total of 176 measurements of hepatic venous pressure gradient(HVPG) were done in 146 patients. Each transjugular HVPG was measured twice, first using an end whole catheter(EH-HVPG), and then using a balloon catheter(B-HVPG). The HVPG was compared with the endoscopic grade of esophageal varices(according to the general rules for recording endoscopic findings of esophagogastric varices), which was recorded within a month of the measurement of HVPG.RESULTS: The study included 110 men and 36 women, with a mean age of 56.1 years(range, 43-76 years). The technical success rate of the pressure measurements was 100% and there were no complication related to the procedures. Mean HVPG was 15.3 mm Hg as measured using the end hole catheter method and 16.5 mm Hg as measured using the balloon catheter method. Mean HVPG(both EHHVPG and B-HVPG) was not significantly different among patients with different characteristics, including sex and comorbid factors, except for cases with hepatocellular carcinoma(B-HVPG, P = 0.01; EH-HVPG, P = 0.02). Portal hypertension(> 12 mm Hg HVPG) occurred in 66% of patients according to EH-HVPG and 83% of patients according to B-HVGP, and significantly correlated with Child's status(B-HVPG, P < 0.000; EHHVGP, P < 0.000) and esophageal varies observed upon endoscopy(EH-HVGP, P = 0.003; B-HVGP, P = 0.006). One hundred and thirty-five endoscopies were performed, of which 15 showed normal findings, 27 showed grade 1 endoscopic esophageal varices, 49 showed grade 2 varices, and 44 showed grade 3 varices. When comparing endoscopic esophageal variceal grades and HVPG using univariate analysis, the P value was 0.004 for EH-HVPG and 0.002 for B-HVPG. CONCLUSION: Both EH-HVPG and B-HVPG showed a positive correlation with the endoscopic grade of esophageal varices, with B-HVPG showing a stronger correlation than EH-HVPG.Eun Ji Lee Yong Jae Kim Dong Erk Goo Seung Boo Yang Hyun-Joo Kim Jae Young Jang Soung Won Jeong 2016World Journal of Gastroenterology2016,22,11:11
3A high-precision phase-derived range and velocity measurement method based on synthetic wideband pulse Doppler radar显示文摘Development of radar technology needs to address the two-dimensional high resolution of range and velocity simultaneously for high-speed targets. Taking advantage of the superior coherent performance of synthetic wideband pulse Doppler radar, this paper elaborates the principles of phase-derived range and velocity measurements. Moreover, this paper explores the key technologies of unwrapping phase ambiguity, and discusses the phase unwrapping strategy at a low signal-to-noise ratio(SNR). The proposed method can be applied to the conditions of low SNR and has comparatively strong practicality in engineering. Both the ejection ball and civil aircraft experiments have validated the correctness and feasibility of the proposed method. In particular,the experimental results reveal that the accuracy of phase-derived range and velocity measurement has reached a level of submillimeter or millimeter and centimeter/second or submillimeter/second, respectively.Huayu FAN Lixiang REN Teng LONG Erke MAO 2017Science China(Information Sciences)2017,60,8:6
4MIMO-SAR waveforms separation based on virtual polarization filter显示文摘The unwanted coupling exists inevitably among multiple orthogonal waveforms in a same frequency area for multiple-input and multiple-output synthetic aperture radar(MIMO-SAR). In this paper, a new polarized MIMO-SAR model is established with two transmitting antennas and multiple receiving antennas at first. Then, a virtual polarization filter(VPF) is proposed to separate superposed returns caused by multiple transmitted waveforms based on detection on the polarized parameters via particle swarm optimizer(PSO).Compared with the conventional matched filter to separate the orthogonal waveforms, it is shown that the coupling noises can be significantly suppressed by the proposed VPF-based method and the orthogonality is not necessary among different transmitting waveforms. Finally, experimental data experiments are also provided to demonstrate the effectiveness of the proposed method.MENG CangZhen XU Jia XIA Xiang-Gen LIU Feng LONG Teng MAO ErKe YANG Jian PENG YingNing 2015Science China(Information Sciences)2015,58,4:4
