简介:摘要:进入二十一世纪以来,我国社会各个领域市场竞争的加剧,企业思考如何最大限度地提高生产效率已成为一项严峻的挑战。我国最近提出了“预防为主,综合管理第一,安全第一”的政策,逐步完善对安全生产的法律和法规,并加强对所雇用的工人的保护,尽可能的减少各种类型的转移,而且项目事故的发生是社会的主要问题。现在,我国正在成为我国生产业发展的瓶颈,最初的一体化发展模式已不再可能实现。如果国内生产企业想要开放市场,调整其现代性和管理体系,需要时间来改变其管理模式,并不断改善处理方法。然而,由于该行业事故率高,因此生产行业最近经历了与生产安全有关的重大事故分析,这对国家,社会和人民都具有重大影响。而且人们要求安装高级安全操作系统,以降低施工安全风险。

简介:用分析,数据由大气的研究的环境预言/公民中心的美国国家中心提供了,在ElNino南部的摆动(ENSO)周期之间的潜在的关系和在从1950~2008的欧亚大陆(乌拉尔,贝加尔湖,和鄂霍次克海)的三个关键区域的堵住的高度被分析。500hPageopotential高度地的合成分析在ElNino的冬季在ENSO的不同阶段期间揭示那(在)年,有在三个关键区域的geopotential高度的重要否定异例。在拉·尼娜(行)年的冬季,在另一方面,geopotential高度的重要积极异例在东方乌拉尔,贝加尔湖,和鄂霍次克海被观察。在夏天,鄂霍次克海展出积极异例,它在一行年的发展中的阶段期间由学生的t测试在90%的信心水平是重要的。在一EN年的发展中的阶段,在500hPa的geopotential高度地表明积极(否定)在贝加尔湖(乌拉尔和鄂霍次克海)的异例,当在500hPa的geopotential高度地展出时积极(否定)在乌拉尔和鄂霍次克海(贝加尔湖)的异例在腐烂的阶段期间在并且行年。然而,这些反常在一在年发展是不足道的,在一腐烂的行年的年,和夏天腐烂。由在ENSO周期的不同阶段期间分析500hPageopotential高度地,案例研究的结果与合成analysis.Annual一般水准堵住的那些一致,这被观察同样与合成分析和案例研究从1950~2008.Combined在ENSO的不同阶段期间被检验,结果显示在三个关键区域的堵住被压制(提高)在冬季期间在(行)年。在夏天,在三个关键区域的堵住上的ENSO的影响在冬季不象那一样重要。显然,开发行可以在堵住上在Okhotsk.Influence因素提高堵住各种各样、复杂。这份报纸显示堵住上的ENSO的影响不能被忽视,并且它对作为一个潜在的信号的相关运作的预报关键。
