| 1 | A Control Strategy for Grid-connected Inverters With LCL Filters显示文摘把LCL滤波器作为电压源型并网逆变器与电网的接口已受到广泛关注。与单电感L滤波器相比,利用电感值较小的LCL滤波器对入网电流的高次谐波具有显著的衰减效果,特别是在低开关频率的大功率并网逆变系统应用中更具明显优势,但是仅采用直接入网电流控制时,LCL滤波器接口的并网逆变器系统存在稳定性问题。该文采用电网侧电感电流和逆变侧电感电流双闭环控制策略对并网电流进行直接控制,电网侧电感电流作为外环更容易抑制并网电流的谐波因素,且可以直接控制入网电流的单位功率因数,采用逆变器侧电感电流作为内环可以增加系统阻尼,从而可抑制系统振荡,增加系统稳定性。对该方案进行系统建模,并深入分析了滤波器参数、控制器参数及系统稳定性之间的精确量化关系。仿真和实验结果表明,该控制策略既可有效抑制入网电流谐振和实现进网电流的高功率因数运行,同时又具有良好的稳态和动态性能。 | HU Xuefeng WEI Zheng CHEN Yihan GONG Chunying ZHANG Jiayan | 2012 | 中国电机工程学报2012，32，27： | 37 |

| 3 | Modification on the tribological properties of ceramics lubricated by water using fullerenol as a lubricating additive显示文摘It is necessary to modify the running-in process for the application of ceramics using water as a lubricant in real conditions because ceramics sliding in water are characterized by a running-in period with severe friction and wear.Fullerenol,a kind of highly water-soluble nanoparticle,was synthesized and then used to ameliorate the tribological properties of Si 3 N 4 sliding against Al 2 O 3 in pure water.With the addition of fullerenol,the running-in period was shortened from 30 min to 100 s at a speed of 250 mm/s.The speed threshold above which ultralow friction can be obtained in a short time was expanded from 450 mm/s to 80 mm/s.Meanwhile,the load-carrying ability of water film was increased.The role of fullerenol was discussed based on observation of the wear scar by an optical interferometer and XPS characterization of the tribo-film on the wear track. | LIU YuHong WANG XiaoKang LIU PengXiao ZHENG JunPeng SHU ChunYing PAN GuoShun LUO JianBin | 2012 | Science China(Technological Sciences)2012，55，9： | 9 |
| 4 | ~1H nuclear magnetic resonance-based metabolomic study on efficacy of Qingrehuatan decoction against abundant phlegm-heat syndrome in young adults with essential hypertension显示文摘OBJECTIVE: To observe the influence of Qingrehuatan decoction(QRHT) on serum metabolic profile in young essential hypertension(YEH) patients with abundant phlegm-heat syndrome and provide a basis for treatment with the decoction.METHODS: Twelve male YEH patients were randomly selected and serum samples were collected for examination before and after 4 weeks of thetreatment with QRHT. Twelve healthy males were randomly selected and their serum samples were collected as a control. All serum samples were detected using metabolomic technology with1 H nuclear magnetic resonance. Differences in metabolites were studied by principal component analysis and partial least squares-discriminate analysis,which produced scores and loadings plots.RESULTS: After 4 weeks of treatment, serum substances could be distinguished between the YEH patients with abundant phlegm-heat syndrome and the control patients. The specific serum endogenous metabolites tended to improve after the treatment. QRHT can appropriately increase the levels of glucose, lactic acid, citric acid, high-density lipoprotein, phosphatidylcholine, glycerophosphate choline, hydroxybutyrate, alanine, and glutamate.QRHT could also decrease the levels of low-density lipoprotein/very low-density lipoprotein, lipids,N-acetyl glycoprotein, and O-acetyl glycoprotein.CONCLUSION: QRHT can effectively ameliorate metabolic disorders in YEH Patients with abundant phlegm- heat syndrome.1H NMR-based metabolomic technology can provide an objective basis for the treatment of YEH patients with abundant phlegm-heat syndrome using QRHT. | Feng Xuanchao Yang Zheng Chu Yuguang Du Bai Su Mei Li Yi Wang Yinghong Jiang Chunying Hu Yuanhui | 2015 | Journal of Traditional Chinese Medicine2015，35，1： | 6 |
| 5 | Ericoid mycorrhizal fungus enhances microcutting rooting of Rhododendron fortunei and subsequent growth显示文摘Adventitious root(AR)formation is a unique feature of plant reproduction and plays a vital role in crop production as many horticultural and forestry plants are propagated through cuttings.A growing number of reports have shown that microbes,particularly mycorrhizal fungi are able to promote AR formation,but the underlying mechanisms remain largely unclear.This study established an in vitro culture system and investigated AR formation in microcuttings of Rhododendron fortunei Lindl.inoculated with Oidiodendron maius Barron Om19,an ericoid mycorrhizal fungus strain.Hormones and precursors involved in the biosynthesis of indole-3-acetic acid(IAA)in Om19 mycelium were analyzed.Om19 was able to produce a large quantity of tryptophan(Trp)and also indole-3-pyruvate(IPA)and IAA,indicating that IAA biosynthesis in Om19 could be through a Trp-dependent pathway.After inoculation of Om19,ARs were quickly formed in microcuttings.Symbiosis related genes were activated in ARs,and Om19 effectively colonized the roots.YUC3,a key gene in plant biosynthesis of IAA and genes involved in nitrogen(N)uptake and metabolism,phosphorus(P)uptake were highly upregulated.Plants absorbed significantly greater quantity of mineral nutrients,and their growth was substantially enhanced compared to the control plants without Om19 inoculation.A working model for Om19 enhanced AR formation was proposed.The rapid formation of ARs in cuttings could be due in part to the induction of IAA biosynthesized by Om19 and also attributed to Trp catalyzed biosynthesis of IAA in plants.AR formation,in turn,provided Om19 preferred sites for colonization.Our study suggested that in addition to promoting AR formation,Om19 could potentially be used as a new biofertilizer for enhancing production of ericaceous plants,such as blueberry,cranberry,and rhododendron. | Xiangying Wei Jianjun Chen Chunying Zhang Hong Liu Xiuxia Zheng Jingli Mu | 2020 | Horticulture Research2020，7，1： | 2 |
| 6 | Symptom clustering in chronic gastritis based on spectral clustering显示文摘OBJECTIVE: Apply spectral clustering to analyze the patterns of symptoms in patients with chronic gastritis(CG).METHODS: Based on 919 CG subjects, we applied mutual information feature selection to choose the positively correlated symptoms with each pattern.Then, we used the Shi and Malik spectral clustering algorithm to select the top 20 correlated symptoms.RESULTS: We ascertained the results of six patterns.There were three categories for the pattern of accumulation of damp heat in the spleen-stomach(0.00332). There were six categories for the pattern of dampness obstructing the spleen-stomach(0.02466). There were two categories for the pattern of spleen-stomach Qi deficiency(0.013 89).There were three categories for the pattern of spleen-stomach deficiency cold(0.009 15). There were five categories for the pattern of liver-Qistagnation(0.01910).There were four categories for the pattern of stagnant heat in the liver-stomach(0.00585).CONCLUSION: Most of the spectral clustering results of the symptoms of CG patterns were in accordance with clinical experience and Traditional Chinese Medicine theory. Most categories suggested the nature and/or location of the disease. | Wenhua Zhu Zhaoxiang Fan Guoping Liu Jianjun Yan Tao Zhong Wu Zheng Ruiqing Wang Chunying Wang | 2014 | Journal of Traditional Chinese Medicine2014，34，4： | 2 |

| 17 | Tuning SMSI to stabilize metallic Pd species:A case study on Pd/TiO_(2) for HCHO oxidation显示文摘Pretreatment of the carrier for supported catalysts can effectively improve the strong metal-support interaction(SMSI)and increase the dispersion of precious metals,which are critical to many important catalytic reactions.In this work,we tuned SMSI on Pd/TiO_(2)catalysts through inducing surface defects of TiO_(2)by pretreated with different atmospheres(H_(2)/N_(2),N_(2),O_(2)/N_(2))at the high temperature(800℃).Multiple characterization results illustrated that surface defects anchored Pd species and thus enhanced their dispersion.During reduction,Ti^(3+)species formed and transferred onto the metallic Pd species and then induced SMSI,which effectively stabilize Pd species in the metallic state.The stronger MSI,the more stability of Pd species.As a case,Pd/TiO_(2)–800H_(2),with strongest MSI,displayed the best HCHO oxidation performance at low temperature(10℃). | Chunying Wang Xiaofeng Liu Jingyi Wang Yaobin Li Shaohua Xie Fudong Liu Changbin Zhang Yuming Zheng Wenpo Shan Hong He | 2024 | Chinese Chemical Letters2024，35，3： | 0 |
