Protein losing enteropathy(PLE), a very rare disease with hypoproteinemia and edema as its characteristics, is caused by various diseases resulting in protein depletion from the gut. The diagnosis is relatively difficult due to its complex *** present paper reported a case whose symptom started with acute diarrhea and *** endoscopies showed digestive *** infusion, Chinese herbal decoction and other symptomatic therapies. The hypoproteinemia become even worse and edema occurred after 4 days' ***(40-60g/d) and modified herbal decoctions were prescribed. A final diagnosis of eosinophilic gastroenteritis(EG) complicated with PLE was confirmed by histopathological examination of a repeated gastroscopy. After three weeks' treatment, the serum albumin level was raised and the edema subsided gradually. In conclusion, herbs may have an effect on PLE patients, but PLE resulting from EG is very complex and easy to misdiagnose, especially in atypical conditions. Further studies are required to find the exact mechanisms.

Mixed-dimensional engineering of perovskite material has been demonstrated as a facile and promising strategy to improve both photovoltaic performance and long-term stability of perovskite solar cells(PSCs).In this study,we report an in-plane preferred orientation of 1D perovskite induced by an ionic liquid(IL)of 1-(3-cyanopropyl)-3-methylimidazolium chloride(CPMIMCl)for the first time via sequential deposition approach,leading to a mixed dimensional perovskite thin *** generated one-dimensional(1D)CPMIMPbI3 with in-plane orientation resides at the grain boundaries of three-dimensional(3D)perovskite can be appreciably observed from the morphology level,leading to creation of high-quality films with large grain size with more efficient defect ***,the dispersion of IL in the bulk phase of perovskite material allows for the formation of 1D perovskite for multiple level passivation to inhibit non-radiative recombination and optimize carrier *** IL engineering strategy not only yields a mixed-dimensional perovskite heterostructure with in-plane orientation 1D perovskite nano-rods but also significantly improves the opto-electronic property with suppressed trap *** a result,the CPMIMCl-treated PSCs show an enhanced photovoltaic performance with a champion power conversion efficiency(PCE)up to 24.13%.More importantly,benefiting from the hydrophobicity of formed 1D perovskite and defects suppression,the corresponding PSC demonstrates an excellent longterm stability and maintain 97.1%of its pristine PCE at 25C under 50%RH condition over 1000 *** research provides an innovative perspective for employing the low dimensional engineering to optimize the performance and stability of photovoltaic devices.

比率制动式发电机差动保护在运行中的问题,主要是电流互感器在外部短路暂态过程中因为饱和效应可能产生误动作;此外,定子绕组短路时发电机一侧可能存在不大的穿越性电流,影响保护动作的灵敏性。本文提出一种改进的基于小矢量算法的发电机差动保护新方案。该方案根据内部故障和外部故障时故障电流特性的不同,使用小矢量算法,对故障性质做出初步判断,并根据不同的故障状态选择合适的制动电流。该方案与传统的差动保护方案相比,提高了可靠性和灵敏度。

大型超临界汽轮发电机组将是我国的主力机组,电抗的增大和定子绕组电阻的减少将使短路电流水平下降,保护灵敏度降低。同时由于结构设计的原因,综合性能较好的一些保护方案如横差保护和不完全纵差保护等将不能应用于大型超临界汽轮发电机。文中重点讨论了匝间短路后各电气量的变化对继电保护的影响。研究表明,发电机发生匝间短路故障后,随着短路匝数的增加,转子二次谐波电流以及单元件横差电流均有较大的变化,以此构成的相应保护方案将能够可靠动作。在此基础上,提出故障分量负序功率方向保护可以作为一重主保护方案,并就该方案在实际应用中所涉及的主要问题提出了看法和建议。

提出一种基于小矢量算法的发电机差动保护新方案。发电机发生故障后的暂态电流中包含各种谐波分量,由于小矢量算法对谐波电流具有一定的放大作用,当两侧电流谐波含量区别较大时,将有利于保护动作。裂相横差保护和不完全差动保护由不同分支组成,两侧电流受故障影响程度也不同,电流谐波含量就有区别,因此可以采用小矢量算法提高保护性能。大型发电机内部故障产生的巨大短路电流可能引起其电流互感器饱和,从而影响保护的动作性能,而基于小矢量算法的差动保护方案具有较强的抗电流互感器饱和的能力。
