针对复杂扰动下微电网难以实现理想动态问题,依据分频框架和线性自抗扰控制(LADRC)理论,提出一种混合储能增强型自抗扰协调控制策略。该方案在外环中引入级联型线性扩张状态观测器(LESO)以输出理想的波动平抑指令,提高抗扰性。同时,在内环的自抗扰控制律中引入参考微分前馈以优化对外环输出指令的跟踪能力,进而改善动态性能。基于理论分析,从扰动观测精度、参考跟踪误差、扰动衰减等方面分析增强型自抗扰协调控制的优越性,并为参数整定提供指导思想。最后,在半实物仿真平台上对所提策略的性能进行对比测试,验证其可行性和有效性。

Starting from the generalized ambiguity function of bistatic SAR （BSAR）, it is shown that 3-D point target estimation can be carried out in space-surface bistatic SAR （SS-BSAR）. Appropriate analytical equations, based on maximum likelihood estimation （MLE）, are derived and confirmed via computer simulation. Furthermore, the performance of the estimate using the Crammer-Rao bound is analyzed for the case in question, thus further revealing the possibility and potential of target 3-D position estimation. Setting the determinant maximum of the information matrix as the criterion, the optimal receiver position and multi-receiver configuration are analytically determined in the SS-BSAR system. Simulation results also validate the correctness of the analytical calculation.

关键词： SS-BSAR position estimation MLE Crammer-Rao bound optimal receiver position

Objective： To observe the effects of red yeast rice（RYR） on blood lipid levels, aortic atherosclerosis（AS）, and plaque stability in apolipoprotein E gene knockout（Apo E-/-） mice. Methods： Twentyfour Apo E-/-mice were fed with a high-fat diet starting from 6 weeks of age. Mice were randomized into three groups（n = 8 in each group）： model group（Apo E-/-group）, RYR group（Apo E-/-＋ RYR group）, and simvastatin group（Apo E-/-＋ simvastatin group）. Eight 6-week-old C57BL/6 mice were assigned as the control group and fed with a basic diet. After 36 weeks, plasma lipids and inflammatory factors were measured. Aortic atherosclerotic lesions by microscope, scanning electron microscope and transmission electron microscope were observed. Plasma levels of interleukin-6（IL-6） and tumor necrosis factor-α（TNF-α） were measured with enzymelinked immunosorbent assay. The level of high sensitivity C-reaction protein（Hs-CRP） was detected by the scattering immunoturbidimetric assay. Protein expression of matrix metalloproteinase-9（MMP-9） and nuclear factor κB（NF-κB） in aorta were tested by immunohistochemistry. Results： Compared with the model group, treatment with RYR significantly decreased the levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol, lipoprotein（a）, and apolipoprotein B100 in Apo E-/-mice（P〈0.01）. Compared with the model group, treatment with RYR decreased the levels of Hs-CRP, IL-6, and TNF-α（P〈0.01）. RYR also reduced the protein levels of NF-κB and MMP-9 of the aorta. Conclusions： RYR has the anti-atherosclerotic and stabilizing unstable plaque effects. The mechanism might be related to the inflammatory signaling pathways.

华北平原是中国人口最多、经济最为发达的地区之一,也是受地震灾害影响最为严重的地区之一。对于该地区断裂活动性和大地震发震机制的研究有利于探索板内地震的发震规律、减轻地震灾害所造成的损失。聊城-兰考断裂是华北平原中南部一条重要的隐伏深大断裂。结合浅层地震勘探、钻孔勘探和第四纪测年方法,对聊城-兰考断裂的活动性进行了精细的研究。坝城寺钻孔揭示聊城-兰考断裂南段错断了全新统底界,为全新世早期活动断裂,揭露出该断裂晚更新世以来造成了4次古地震事件,单次事件的垂直位错为1.2±0.2~3.7±0.2 m。根据钻孔揭示的地层落差计算出该断裂晚更新世早期的平均垂直滑动速率约为0.1±0.05 mm/a,晚更新世晚期—全新世中期的平均滑动速率为0.35±0.04 mm/a。根据1937年菏泽7.0级和6(3/4)级地震的等震线和地表破裂分布特征认为,小留-解元集断裂和东明-成武断裂为该地震的发震断裂;聊城-兰考断裂对于该地区应力的积累、地震的发生具有很好的控制和约束作用,为区域控震构造。

Nanopore is an ultra-sensitive electrochemical technique for single molecular detection in confined space. To suppress the noise in detection of the weak current of nanopore, we investigated the influence of membrane capacitance and applied voltage on the noise of the current signal by model analysis, simulation and experiment. The obtained results demonstrated that membrane capacitance affects the noise by amplifying the noise of the applied voltage. Therefore, suppression of applied voltage noise is an efficient approach for reducing the noise in nanopore detection. Here, we developed an ultra-low noise instrument system for detecting the single molecule signal in nanopores. As demonstrated by nanopore experiments, the p-p noise of the developed system during the recording is reduced to 3.2B pA using the filter of 5 kHz. Therefore, the developed system could be applied in highly sensitive nanopore detection.
