There are generally zero drift, sensitivity drift and nonlinear error in silicon piezoresistive pressure sensors due to the inherent characteristics of semiconductor materials. It is necessary to compensate and correct the errors produced so as to meet the requirements of measurement accuracy. In order to further improve the compensation precision, based on the research of various basic software compensation methods, a surface fitting compensation algorithm based on least square method is designed, and the software is implemented on the Visual Basic platform. The experimental results show that the zero drift, sensitivity drift and nonlinear error is effectively eliminated, and the output precision of the sensor is greatly improved.

The stress wave sensor detect and process the electronic signal of friction, mechanical shock and dynamic load on equipment moving parts, the stress wave analysis are fulfilled by using the time domain and frequency domain feature extraction software, Polynomial neural network(PNN) and data fusion technology. The equipment status are quantitatively analyzed, the equipment fault are accurately predicted. Compared with the current adopted other analysis technologies, the system can monitor the operation condition of the equipment better in real-time, predict the fault earlier. The production safety is guaranteed, the equipment maintenance cost is reduced, and the production efficiency is improved.

High-fat diet (HFD) consumption induces gut microbiota dysbiosis and neuropsychiatric disorders， including anxiety. Previous research found that Tremella polysaccharide (TP) exhibited neuroprotective effects in vitro and in vivo. This study aimed to investigate the beneficial effects of TP on HFD-induced anxiety-like behaviors and elucidate the underlying mechanisms from the point view of the microbiota-gut-brain axis. Two groups of HFD-induced obese mice were orally gavaged with low dose (TPL， 40 mg/kg) and high dose (TPH， 400 mg/kg) of TP. A 12-week administration of TPH could significantly improve anxiety-like behaviors in HFD mice. In the hippocampus， microglia activation， the expression of blood-brain barrier (BBB) markers， and the levels of two neurotransmitters (serotonin and norepinephrine) were countered by TPH in mice consuming HFD. Furthermore， TPH improved the intestinal permeability and immune response of the enterocytes in HFD-fed mice. The gut microbiota dysbiosis induced by HFD was also rebalanced by TP treatments， especially in Proteobacteria and its lower taxa. The correlational analysis also suggested that shifts of some microbial genera were closely associated with body weight and the parameters of behavioral tests. Interestingly， fecal microbiota transplantation (FMT) results indicated that fecal microbiota from TPH-treated obese mice could prevent HFD-induced anxiety-like behaviors， suppressing microglia activation and intestinal permeability. In conclusion， the present study indicated that TP intake is a promising dietary intervention strategy to prevent HFD-induced anxiety via the microbiota-gut-brain axis.

鲁迅体裁选择刍议

鲁迅研究月刊 2023年第9期 25-31页

作者：陈漱渝北京鲁迅博物馆 100034

概念是在感性认识基础上抽象提升而为的理性认识,有其特定的内涵(即准确的定义)和外延(即明确的划分)。但在中国新文学的建设时期,批评界使用的名词概念——特别是从域外引进的——往往具有不同程度的模糊性。本文通过鲁迅本人对“文体... 详细信息

概念是在感性认识基础上抽象提升而为的理性认识,有其特定的内涵(即准确的定义)和外延(即明确的划分)。但在中国新文学的建设时期,批评界使用的名词概念——特别是从域外引进的——往往具有不同程度的模糊性。本文通过鲁迅本人对“文体”和“体裁”概念的理解和使用,反映出这种复杂的历史现象,并试图论述杂文体裁在鲁迅作品中的崇高地位,以及鲁迅运用这种体裁的主观因素和特殊文化环境。鲁迅杂文不仅具有不容抹杀的历史价值,而且具有不容否定的现实意义。

平民指劳苦大众。鲁迅一贯站在平民立场判断是非,决定爱憎取舍。鲁迅跟中国的左翼作家一样,经历了一个从“要求人性的解放”到“阶级意识觉醒”的过程。神化任何历史人物都是错误的。但不能忽视或否定鲁迅的主要业绩,刻意渲染鲁迅的世俗化生活。要准确评价鲁迅的历史功过,可以采用文史互证的方法,用确凿的历史事实证明鲁迅的历史贡献及其不可避免的时代局限,使论点经受住严格的学术检验。

鲁迅的文化遗产与当代中国

作者：陈漱渝

在世界文化史上有三类文艺家.一类在他们生活的年代一度享有盛誉,但逐渐被读者淡忘了,比如英国戏剧家马洛(1564—1593),是中世纪戏剧的革新者.他的作品为莎士比亚的创作铺平了道路.

《〈鲁迅杂感选集〉序言》是作为革命家的瞿秋白在避难期间仅用三、四个晚上写就的学术论文,也是鲁迅研究史上的经典之作。此文从社会政治的角度研究鲁迅的杂文创作和思想发展,得出了一些为鲁迅本人首肯的结论,产生了重大深远的影响。虽然政治视角并不是研究鲁迅的唯一视角,却是把握鲁迅本质特征的重要视角,作为一篇历史文献,瞿秋白的序言有其历史局限性,但主要体现在哪些方面,鲁研界仍见仁见智,可以进行深入的学术探讨。
