“大报”与“大气”

何谓大报? 党报就是大报--这是许多读者与报人的习惯说法.这当然是因为党报融"严肃性、权威性、指导性"于一身,能够为读者提供可靠、严谨的信息,能够及时把党的声音传递给受众.

翻译佛经语料年代的语言学考察——以《大方便佛报恩经》为例

《大方便佛报恩经》,七卷。大藏经题署“失译,附《后汉录》”。学者通常把它当作东汉语料来用,值得商榷。本文尝试从语法(判断句、被动句和疑问句)、词汇(一般语词和“～切”式复音词)的某些角度,对其翻译年代进行推定。本文认为,《大方便佛报恩经》所反映的语法词汇面貌与可靠的东汉译经不同,应该是魏晋以后的译经。

置疑“小报小刊”及其它

现下．“小报小刊”、“子报子刊”的称谓使用频率颇高。人们不仅嘴上说、笔下写，而且赫然出现在官方的红头文件中。那么，何谓“小报小刊”、“子报子刊”呢？窃以为，此种称谓，值得商榷。

Design and implementation of low-cost geomagnetic field monitoring equipment for high-density deployment

The observation of geomagnetic field variations is an important approach to studying earthquake precursors.Since 1987,the China Earthquake Administration has explored this seismomagnetic relationship.In particular,they studied local magnetic field anomalies over the Chinese mainland for earthquake prediction.Owing to the years of research on the seismomagnetic relationship,earthquake prediction experts have concluded that the compressive magnetic effect,tectonic magnetic effect,electric magnetic fluid effect,and other factors contribute to preearthquake magnetic anomalies.However,this involves a small magnitude of magnetic field changes.It is difficult to relate them to the abnormal changes of the extremely large magnetic field in regions with extreme earthquakes owing to the high cost of professional geomagnetic equipment,thereby limiting large-scale deployment.Moreover,it is difficult to obtain strong magnetic field changes before an earthquake.The Tianjin Earthquake Agency has developed low-cost geomagnetic field observation equipment through the Beijing–Tianjin–Hebei geomagnetic equipment test project.The new system was used to test the availability of equipment and determine the findings based on big data..

论生态环境损害赔偿司法确认制度的构建

现有制度体系下,生态环境损害赔偿磋商协议的执行保障依靠民事司法确认制度。生态环境利益的公益属性与民事权益的私益属性形成强烈反差,民事司法确认制度建构以私益为基础,难以满足生态环境利益救济的需要,基于现实需求,生态环境损害赔偿司法确认制度亟待建立。在制度构建过程中,要明确生态环境损害赔偿司法确认制度与民事司法确认制度的差异,把握住生态环境利益的公益属性,将更好地实现受损生态环境利益的救济作为根本追求,以专业性为依托,从申请方式、管辖法院等五个维度完成制度核心的构建,进而保证受损生态环境利益救济的质量与效率。

考虑滑面材质的碎屑流试验堆积特征分析

为分析高速远程滑坡运动与堆积特征,在室内设置物理试验模型,设计级配、坡角、碎屑流质量、滑面材质4种因素,分析各因素对碎屑流堆积特征的影响。研究结果表明:坡角减小、滑面更粗糙使部分颗粒堆积或滞留于坡面,颗粒堆积特征与颗粒完全堆积于坡底时相比存在差异;滑面材质与冲程等堆积特征基本呈负相关,坡角与堆积特征基本呈正相关,二者对堆积特征影响最大;碎屑流质量与堆积特征基本呈负相关,对颗粒堆积特征分布影响较小;级配与颗粒堆积特征无明显相关性。

Design of Offshore Wind Power Foundation with Multi-bucket

Three- and four-bucket offshore wind power foundations with a new form of force-transferring structure are proposed in this paper, and the integrated finite element model of foundation-soil-transition structure is established by using ABAQUS. The carrying capacity of the proposed foundations is studied under vertical load, horizontal load and bending moment. It can be seen that the vertical bearing capacity of multi-bucket foundation can be roughly estimated by the vertical bearing capacity of single-bucket; the horizontal bearing capacity of the three-bucket foundation scheme is controlled by displacement, while that of the four-bucket foundation scheme is controlled by the internal forces of soils. Moreover, the carrying capacity is provided by the overall structure formed by multi-bucket before soil failure. Compared with the conventional single-bucket foundation, there are mainly tension and pressure that are applied to the multi-bucket foundation, so that the carrying capacity of the foundation can be fully utilized. The probability of soil failure can be well reduced with the proposed multi-bucket foundation, and the stress transmission of force-transferring structure is more consistent through steel beams with variable cross-section.

Fault Diagnosis of Valve Clearance in Diesel Engine Based on BP Neural Network and Support Vector Machine

Based on wavelet packet transformation(WPT), genetic algorithm(GA), back propagation neural network(BPNN)and support vector machine(SVM), a fault diagnosis method of diesel engine valve clearance is presented. With power spectral density analysis, the characteristic frequency related to the engine running conditions can be extracted from vibration signals. The biggest singular values(BSV)of wavelet coefficients and root mean square(RMS)values of vibration in characteristic frequency sub-bands are extracted at the end of third level decomposition of vibration signals, and they are used as input vectors of BPNN or SVM. To avoid being trapped in local minima, GA is adopted. The normal and fault vibration signals measured in different valve clearance conditions are analyzed. BPNN, GA back propagation neural network(GA-BPNN), SVM and GA-SVM are applied to the training and testing for the extraction of different features, and the classification accuracies and training time are compared to determine the optimum fault classifier and feature selection. Experimental results demonstrate that the proposed features and classification algorithms give classification accuracy of 100%.

Estimation of DOA and Polarization Parameters with 2-Level Nested Vector-Sensor Array Based on Quaternion Model

The quaternion coherence problem exists in the data model of the conventional dimensional reduced quaternion estimation of signal parameters via rotational invariance techniques(DRQ-ESPRIT), and DRQ-ESPRIT would lose degrees of freedom(DOFs)when it is used to implement the spatial smooth operation. An improved DRQ-ESPRIT algorithm based on 2-level nested vector-sensor array is proposed in this paper. The quaternion coherence problem is solved by switching the multiplication sequence of spatial direction vector and electric field. Meanwhile, nested array and Khatri-Rao subspace approach are used to increase the number of DOFs, thus the proposed algorithm can estimate more incident sources than DRQ-ESPRIT, and the estimations of direction of arrival(DOA)and polarization parameters are more accurate. Simulation results demonstrate the effectiveness of the proposed algorithm.

A Potential High-Score Scheme for the Prediction of Atlantic Storm Activity

A new empirical approach for the seasonal prediction of annual Atlantic tropical storm number (ATSN) was developed using precipitation and 500 hPa geopotential height data from the preceding January February and April May.The 2.5°×2.5° resolution reanalysis data from both the US National Center for Environmental Prediction/the National Center for Atmospheric Research (NCEP/NCAR) and the European Center for Medium-Range Weather Forecasting (ECMWF) were applied.The model was cross-validated using data from 1979 2002.The ATSN predictions from the two reanalysis models were correlated with the observations with the anomaly correlation coefficients (ACC) of 0.79 (NCEP/NCAR) and 0.78 (ECMWF) and the multi-year mean absolute prediction errors (MAE) of 1.85 and 1.76,respectively.When the predictions of the two models were averaged,the ACC increased to 0.90 and the MAE decreased to 1.18,an exceptionally high score.Therefore,this new empirical approach has the potential to improve the operational prediction of the annual tropical Atlantic storm frequency.

Genes, emotions and gut microbiota:The next frontier for the gastroenterologist

Most medical specialties including the field of gastroenterology are mainly aimed at treating diseases rather than preventing them. Genomic medicine studies the health/disease process based on the interaction of the human genes with the environment. The gastrointestinal(GI) system is an ideal model to analyze the interaction between our genes, emotions and the gut microbiota. Based on the current knowledge, this mini-review aims to provide an integrated synopsis of this interaction to achieve a better understanding of the GI disorders related to bad eating habits and stress-related disease. Since human beings are the result of an evolutionary process, many biological processes such as instincts, emotions and behavior are interconnected to guarantee survival. Nourishment is a physiological need triggered by the instinct of survival to satisfy the body's energy demands. The brain-gut axis comprises a tightly connected neuralneuroendocrine circuitry between the hunger-satiety center, the dopaminergic reward system involved in the pleasure of eating and the gut microbiota that regulates which food we eat and emotions. However, genetic variations and the consumption of high-sugar and high-fat diets have overridden this energy/pleasure neurocircuitry to the point of addiction of several foodstuffs. Consequently, a gut dysbiosis generates inflammation and a negative emotional state may lead to chronic diseases. Balancing this altered processes to regain health may involve personalized-medicine and genome-based strategies. Thus, an integrated approach based on the understanding of the gene-emotions-gut microbiota interaction is the next frontier that awaits the gastroenterologist to prevent and treat GI disorders associated with obesity and negative emotions.
