2004年中国钢材市场分析及2005年展望

2004年中国钢材市场需求旺盛增长，资源供应充足，价格行情剧烈震荡。预计新一年需求形势依然看好，新增资源可以满足消费需求，供求关系拉动价格进一步上涨的空间不大；另一方面，全球性原料价格居高不下，持续抬高钢材生产成本，整体钢材市场价格坚挺，深幅下跌的可能性亦不大。此外，种种迹象表明，国际钢材市场价格已近峰顶，今后有可能向下调整，但由于目前国内钢材价格已经低于国际水平，因此，

河北省冶金工业改革与发展的足迹

1992年至1997年的5年间，河北省冶金工业战线抓住机遇，深化改革，扩大开放，加快发展，积极进行“第二次创业”，加速增长方式转变，实现了持续快速发展，整体实力增强，经济效益提高。理顺思路：唱好结构调整“重头戏”1991年，全省产钢420万吨，生铁59O万吨，钢材327万吨，已脐身于全国几个钢铁大省行列。但是，比较而言，整个冶金工业运行质量还不够高，产品结构不合理、比例失调的问题还比较严重。突出的矛盾是结构不合理，主要表现是：铁多，钢少；普碳钢多，优质钢少；钢材品种大路货多，高技术、高附加值的钢材少；企业分散，规模…     

An in vitro and in vivo analysis of anodized tantalum capacitive electrodes: corrosion response, physiology, and histology

Oxidation-reduction reactions which can destroy high current-density metal-stimulating electrodes are avoided when using capacitive electrodes. The results of in vitro and in vivo testing of anodized, high surface area, sintered tantalum electrodes are presented. The corrosion response of the electrodes is excellent; there is no evidence of dissolution of the electrode. A deposit forms on the surface of the electrodes, but has little effect on the voltage response to constant current stimulation. The physiological and histopathological results indicate the capacitive tantalum electrode to be the safest yet tested.

Influence of non-uniform material properties and water cooling on current density and temperature profiles in arc furnace electrodes

The influence of the simplifying assumption of constant electrical conductivity on the modelling of current density and temperature profiles in arc furnace electrodes is investigated in comparison with calculations taking into account the complete interdependence of electrical and thermal effects. With respect to the accuracy of the calculated values for UHP arc furnace electrodes it is shown that the classical theory for the skin effect using the approximation of constant electrical conductivity is inferior to an exact numerical evaluation, especially concerning the current distribution. A two-dimensional thermal analysis is performed for combination electrodes consisting of a water cooling shank and a graphite wearing part, in order to demonstrate the cooling effect for the reduction of graphite consumption. In the electrodes considered here, the cooled region in the wearing part covers an axial distance in the order of one electrode diameter.     

Origin of tonic electrical activity patterns in the diaphragm of the fetal lamb

The respiratory pattern generator in fetal and postnatal life activates the phrenic nucleus and diaphragm muscle with phasic bursts of activity. In the fetus, diaphragmatic activity is also characterized by tonic activity patterns of unknown origin. We have examined whether such activity is diaphragmatic, or radiated from nearby ribcage muscles, by placing two sets of electrodes side-by-side in the costal portion of the diaphragm in five fetuses. The rationale for this approach is that if tonic activity, radiates to the diaphragm it should be recorded by both sets of electrodes and there should be no delay between the action potentials from each set of electrodes. Of 24 single tonic units identified, 15 were recorded from only one of the two sets of electrodes in the diaphragm. In the 9 tonic units recorded from both sets of electrodes, there was a time delay between the appearance of the action potentials in the two recordings (mean +/- S.E.M. 1.6 +/- 0.2 ms). This is the expected conduction delay along the muscle fibres separating the two electrodes. Since tonic diaphragmatic activity persisted in fetuses with the spinal cord transected rostral or caudal to the phrenic nucleus, we conclude that the spinal cord alone is sufficient to produce the tonic activity recorded from the fetal diaphragm but that the brain may also generate such activity.     

A decade of rare donor services in the United States. Report of the American Red Cross Rare Donor Registry (1981-1990)

As a substitute for depth electrodes, mesial temporal subdural electrodes were devised. This electrode has a slender trapezoid shape and is easily introduced to the inner uppermost portion of the parahippocampal gyrus. Our results have shown that mesial temporal electrodes can detect not only interictal spikes but also subclinical and clinical seizure discharges from the mesiolimbic structures, and they have excellent capability for lateralization of the mesial temporal epileptic focus. If mesial temporal subdural strips are used in combination with lateral temporal subdural grids, comprehensive understanding of the focus distribution throughout the temporal lobes will be possible without using depth electrodes.

Possibility of the production of consumable electrodes for electroslag remelting using prereduced pellets: Part 1

The high cost of the metal produced by electroslag remelting is caused by the significant costs of the manufacture of consumable electrodes. From an economic efficiency standpoint, it is reasonable to further develop the methods of forming consumable electrodes by pouring into a special-purpose mold. One of the ways to decrease the cost of electroslag metal is the formation of consumable electrodes from prereduced pellets. In this work, the problems related to the use of prereduced pellets for electroslag remelting are considered.     

A Comparative study on the Performance of Different Sintered Electrodes in Electrical Discharge Machining

In this research two different materials have been machined by sintered copper, brass, and bronze electrodes in electrical discharge machine. The input parameters are varied and output responses have been studied by adopting design of experiments. Response surface methodology has been adopted for analysis of the parameters. Mathematical model has been formulated for all sintered electrodes and to optimise the parameters to obtain maximum material removal rate , minimum tool wear rate and minimum surface roughness. The effects of interaction of parameters has been studied among the three sintered electrodes. Copper electrodes removes high rate of material compared with sintered brass and sintered bronze electrode. Tool wear rate is high for brass electrode.
