浅谈煤矿班组安全建设中几点行之有效的做法

俗语道：基础不牢,地动山摇。班组是落实安全生产最基层的生产组织,是一切安全工作的落脚点,是加强企业管理、搞好安全生产、减少伤亡和各类灾害事故的基础,是实现企业安全目标的关键。     

守住安全生产最后一道关口——聚焦湖南省安全生产应急救援工作

<正>应急救援是安全生产的最后一道关口,应急管理是把好这道关口的基础。随着经济社会发展日新月异,安全生产应急管理任务也日趋艰巨。只有扎牢这道口子,事故发生后,才能及时正确地处置,有效防止事故扩大。近年来,湖南省安全生产应急救援机构进一步加强,应急救援队伍建设稳步推进,预案体系建设不断强化,应急救援指挥平台建设升级提速,应急处置和应急值班值守工作明显加强,基层基础工作进一     

“工具箱”为烟草行业保安全

每一年,国内外都会发生多起触目惊心的安全事故.这些安全事故发生的原因多种多样,但研究发现,如果安全生产的管理工作能够做到位,那么就能避免许多事故的发生.同样的,笔者发现国内烟草行业对于安全工作的管理力度也尚有欠缺.如何及时发现和处理安全隐患,避免安全事故呢？笔者结合自己的工作经验,创建了“基层安全管理数字化工具箱”的安全管理项目,有效减少和避免了安全事故. “基层安全管理数字化工具箱”是什么东西？这个新创的项目主要是以机器管理人员的工作理念,以浙江省烟草专卖局“安全保卫管理信息系统”为技术平台,利用二维码扫描技术,在手持终端设备上装设自动扫描程序,实现安全二维码扫描,最终完成安全巡查的工作.之所以称为“工具箱”,主要是这项技术中包括了PDA、二维码扫描打印机等多种数字化工具.

浅谈施工现场用电安全管理

近几年来,各地建筑施工现场安全事故时有发生,其中触电事故已是建设工程发生事故的主要因素之一。随着《安全生产许可证条例》等有关安全生产法律法规的颁布实施,安全生产事故得到有效的控制,施工现场临时用电得到充分重视,我们必须通过强化现场管理来降低触电事故的发生。本人从事工程项目管理多年,比较重视用电安全管理,所实施管理的项目,没有发生重大触电事故,现就施工现场用电安全管理谈谈一些经验方法。     

建筑工程施工项目危险源的应急控制策略研究

事故发生一般经历四个过程:存在事故隐患-出现危险征兆事故-临界状态-进入事故过程。在事故经历的四个过程中,对存在事故隐患-出现危险征兆这两个过程的安全管理属于事故预防管理阶段;对事故临界状态-进入事故过程这两个过程的安全管理属于事故应急管理阶段。事故临界状态应急降低隐患转化为事故的概率或降低事故损失的严重程度;事故过程应急仅能降低事故损失的严重程度。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
