工地作业是一个庞大的工程,工程质量不仅关系到作业者的生命安危,更是以后使用者的忧虑所在,所以,每一个细节的质量都是至关重要的。这就要求施工者在各种材料质量合格的情况下工作要一丝不苟,把人为因素降到最低甚至连一个小螺丝也不可轻视。在通常的作业操作时,人们经常会遇到一字螺丝钉和十字螺丝钉同时存在的问题,人们找到了很多解决办法,但是,都需要双手进行配合或者两种改锥轮换操作,在杂乱的工具箱里挑拣工具,给作业带来很多不便,不仅降低了工作效率,而且影响到施工者的心情。 相似文献

政府部门中的潜规则是指在政府管理中跟国家权力的行使直接相关与政府正式规章制度相悖的“地下规则”。根据近十年有关“潜规则”的报道,政府部门中的潜规则可以分为人事选拔和考核、政府采购、拆迁和土地出让以及除上述以外的其他方面四类。其影响虽有积极方面,但更多的是消极的影响,需要在对潜规则研究基础上,在加强思想教育、完善正规则、加强监管上下功夫。 相似文献

Hydroxylated/methoxylated polybrominated diphenyl ethers (OH/MeO-PBDEs) are not only detected as natural products, but also regarded as metabolites formed from polybrominated diphenyl ethers (PBDEs), which are widely used as flame-retardants in various materials. The aim of the present study was to synthesize authentic OH-PBDEs and MeO-PBDEs, as reference standards for environmental exploration. Twenty OH-PBDEs and their corresponding MeO-PBDEs containing three to six bromine atoms were synthesized via a trial of reactions including coupling, oxidation, bromination, methylation, etc. The products were characterized by GC-MS and 1H-NMR spectroscopy in the work. As results show, all compounds synthesized were up to 99% on purity and be reqarded as authentic standards for detecting the chemical pollutants in the emvironment. 相似文献

The reaction kinetics of the heterogeneous oxidation oftoluene with Mn^3 was studied by considering the effects of disproportionation of Mn^3 in reaction system,a “parallel”modulus was set up.And then the concentration of Mn^3 in disproportionation and the concentration of benzaldehyde in oxidation were respectively determined in turn.the rate constant,order and pseudo-activation energy of the heterogeneous oxidation were obtained by mathematical deduction and the kinetic equation was concluded.In addition,the reaction mechanism was analyzed.It shows that the results are completely consistent with modulus. 相似文献

The preparation of nanometer γ-Fe2O3 through an electrochemical process was studied at room temperature, using a metal iron plate as sacrificing anode and a sheet of stainless steel as cathode, in non-aqueous mediate containing ( Bu)4 NBr as support electrolyte and 2 % (vol % ) water. The powdery particles obtained were then calcined at 300 ℃. The products were characterized by IR, XRD,SEM, TEM and laser particle size analyser, indicating the fine particle is a pure nanometer γ-Fe2O3. The morphology is like coneshaped and their average size is 22.0 nm. Furthermore the VSM spectrum shows that the particle's coercivity (3.9 × 103 A/m) is rather small, presenting the excellent super-paramagnetism. 相似文献
