本文综合分析了不锈钢冶炼和铬矿还原的理论和工艺。

The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

基于碱金属对高炉冶炼的上述危害，本文结合湘钢高炉的实际生产情况，通过理论分析、计算以及其他钢厂防治碱害的经验，提出防治高炉碱害的措施：1、减少入炉原、燃料的碱金属含量；2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量；3、采用预还原的金属化球团或部分还原的烧结矿；4、提高焦炭的抗碱能力；5采用抗碱侵蚀的耐火材料；6、周期性性洗炉，以有效地减少碱金属在高炉内的循环富集，降低碱金属对高炉的危害，提高高炉的冶炼强度，降低焦比，改善高炉透气性。

We can now understand the motivation for full-blown reduction.

我们现在能理解完全还原的动机了。

The issue is closely parallel to that of the irreducibility of teleological explanation.

这个议题平行于对不可还原的目的论解释。

They won't be able to get to it to destroy it and once started the process is irreversible.

他们将不能够到达它破坏它而且一旦开始程序是不能还原的。

The results show that:①The forest soils have the stronger nitrification, but also the nitrification in surface horizon is stronger than the undersoil's.

结果表明：①森林土壤有较强的硝化活性，且表土层比底层土强，同时根际土利于硝化作用进行，根际效应R/S在4.5左右；②淹水厌气培养24h，-N的消失率为52%～58%，占第10天的55%～71%，且表土层-N的消失率比底层土大；③参与同化反硝化作用的还原酶活性较强，在培养24h后，被还原的基质数量占加入基质数量的70%～90%。

Inthe last stage of reduction,the iron substrates formed on the surface of Wüstite areporous and permeable to gaseous diffusion.The reduction rate is controlled by thesurface reaction on the Wüstite-iron interface,but the rate of this surface reactionis limited by the velocity of CO formation.

在浮士体还原成金属铁的阶段，所生成的多孔性金属铁并不阻碍气相的扩散；还原的速率由浮士休-金属铁相界面的表面反应所控制，而表面反应的速率则受CO的生长速率所限制。

It was found from structure-electrochemical studies of hemoglobin that (1) electroreduction induces the T→R transition with chirality transition and umbrella conversed effect;(2) electric field induces the secondary structural transition between two α helices, which is smilar to the denaturalization of the protein;(3) The electrochemical reaction mechanism of EC including T→R transition and parameters have also been obtained.

在血红蛋白的结构-电化学研究中发现：（1）电化学还原诱导血红蛋白的T→R构型转化，手性转化的伞翻转效应；（2）电场诱导血红蛋白的两种α螺旋二级结构间的转化，属于电场诱导血红蛋白的部分变性；（3）获得血红蛋白电化学还原的包括R→T转换的EC机理和参数

It was found from the structure-electrochemical studies of myoglobin that (1) electroreduction induces the T→R configuration transition with peak shift in CD spectra and without umbrella conversed effect, which proved that umbrella conversed effect is mainly the cooperation of four subunits in hemoglobin;(2) the mechanism of EC with adsorption of reduction product and parameters have also been obtained.

肌红蛋白的结构-电化学研究中发现：（1）电化学还原诱导了肌红蛋白的T→R构型转化，伴随着CD谱的峰位移，但没有象血红蛋白那样明显伞翻转效应，表明伞翻转效应是多个亚基共同作用的结果；（2）获得肌红蛋白电化学还原的EC机理，并伴随产物吸附的自阻碍过程及其参数。

If one is a materialist but believes that all reductive efforts have failed and that a non-reductive materialism is incoherent, then one can adopt a final, more radical position: eliminative materialism.

如果一个人是唯物主义者但相信所有还原的努力都已经失败了，以及一个非还原的唯物主义是条理不通的，那么一个人接受一个最终的、更激进的立场是：取消的唯物主义。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
