By the reduction of mill scale of rimmed steel with charcoal,a high gradeiron powder(>98.5% Fe)suitable for powder metallurgy can be obtained. In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.Therefore the last stage reaction controls the whole reduction process.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.The activation energy for the growth of iron substrates on the Wüstite surfacewas determined to be 57000 cal/mole,being comparable to the activation energyfor CO formation in most solid reducing agents such as coke,graphite and coal.Experimental results rther indicate that the effect of temperature on the reduc-tion rate of Wüstite arises from the temperature dependence of CO generation oncharcoal.

用木炭还原沸腾钢铁鳞,可获得含铁>98.5%,适合于粉末冶金用的优质铁粉.在1000℃左右的还原过程中,在金属铁出现之前,在数分钟内Fe_2O_3和Fe_3O_4几乎都已全部还原成浮士体,但后者还原成金属铁的阶段,则须经历数十分钟之久,因此后一阶段便成为还原过程中控制的一步.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。浮士体表面的金属铁层成长所需的激活能约为57000卡/克分于,与用固体碳发生CO的反应所需的激活能相同。实验的结果更指出,不同温度下浮士体还原速率个同的原因,是由温度对CO发生速率的影响所引起。

The cell free preparation of a strain of P seudomonas fluorescens was capable of catalyzing the reduction of both NADP~+ and NAD~+ in presence of glucose-6-phospha(?)e.The reduction of both nicotinamide nucleotides is considered to be catalyzed by the same enzyme based on the following evidence.(1) No nicotiamide nucleotide transhydrogenase activity can be demonstrated in the cell free extracts of the bacteria.(2) During purification up to an electrophoretically homogeneous preparation (130-fold enrichment), the rate of reduction of NADP~+ and NAD~+ in presence of glucose-6-phosphate has a constant ratio about 2:1.(3) The rate of the reduction of NADP~+ catalysed by the enzyme is about 2 times as fast as that of NAD~+.When both NADP~+ and NAD~+ are added simultaneously in the system, the reduction rate approximates that for NADP~+ alone.

在一株萤光假单孢杆菌SM-102菌株中G-6-P脱氢酶能同时利用NADP~+和NAD~+作为氢递体,并非象以往文献所载在G-6-P脱氢酶催化G-6-P的氧化中所引起NAD~+的还原是由于烟酰胺核甙酸转氢酶的作用所致,这个结论是根据下列的试验结果: (一)经测定在细菌的无细胞抽提液中没有找到烟酰胺核甙酸转氢酶的存在。(二)电泳纯的酶制剂亦能同时利用NADP~+和NAD~+作为氢递体。(三)在酶的纯化过程中,G-6-P脱氢酶作用于NADP~+和NAD~+的还原速率比值始终保持在2左右。(四)G-6-P脱氢酶作用于过量辅酶的反应系统时,对NADP~+的还原速率约为NAD~+的二倍,但当NADP~+和NAD~+同时存在时,还原速率仍与NADP~+相等。作者对G-6-P脱氢酶能同时以NADP~+与NAD~+作为辅酶在糖代谢演化上的意义进行了讨论。

The cold-rolling and recrystallization textures of Fe-Si (3.25% Si) single crystals with orientations close to (110) [001], (320) [001] and (110) [1(?)2] were investigated. As the reduction increased from 60 to 85 pct, for lower rates of reduction, the recrystallization texture of (110) [001] single crystal changed gradually from the (110) [001] to (310) [001] orientation, but it remained in the (110) [001] orientation in the case of higher rates of reduction.

The cold-rolling and recrystallization textures of Fe-Si (3.25% Si) single crystals with orientations close to (110) [001], (320) [001] and (110) [1(?)2] were investigated. As the reduction increased from 60 to 85 pct, for lower rates of reduction, the recrystallization texture of (110) [001] single crystal changed gradually from the (110) [001] to (310) [001] orientation, but it remained in the (110) [001] orientation in the case of higher rates of reduction. The behavior of the (320) [001] single crystal during coldrolling was similar to the (110) [001] single crystal, whereas in the (110) [1(?)2] single crystal the rate of reduction showed no pronounced effect on the recrystallization texture.These results were discussed according to the theory of recrystallization in situ, and the change of recrystallization textures with reduction rates can be explained satisfactorily.

研究了取向接近(110)[001]、(320)[001]和(110)[1(?)2]的鉄硅(3.25% Si)单晶体,在采用不同的压下速率(每軋制一次的压下量)經过60%,70%,80%和85%軋制后的冷軋和再結晶織构。(110)[001]取向的单晶体在采用較低的压下速率軋制退火后,再結晶織构随着压下量增加会从(110)[001]逐漸变化到(310)[001],但采用較高的压下速率軋制退火后,再結晶織构都是(110)[001],并不随压下量增加而改变。改变軋制时的压下速率,对(320)[001]取向单晶体的再結晶織构也有与以上相似的影响,但对(110)[1(?)2]取向单晶体的再結晶織构就沒有明显的影响。分析实驗結果后,认为再結晶織构的形成是一种同位再結晶过程,从这种观点出发,可以滿意地解释再結晶織构随压下速率及压下量改变而变化的規律。
