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.

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。

The effect of transgenx Bt cotton on non-target insects The kinds of the dominant species of pests in transgenic cotton field had obvious change, in which the H. armigera was no longer the main pest and the piercing-sucking pests such as Aphis gossypii, Tetranychus urticae, Thrips tabaci etc. rose the main pests. The kinds of the dominant species of predatory natural enemies seemed to be no variation, which was still Propylaea japonica Thunberg. Because of the effect of transgenic Bt cotton on H. armigera laevae-the development delay, the weight reduction, which affected the qualities of parasitic enemies, leading to the reduction of the weight of cocoon and the weight of adult, and the reduction of H.

转Bt基因棉对节肢动物群落整体结构及时序变化的影响 2001保铃棉与冀抗668的相似系数最高(0.8246)，冀抗668、保铃棉与常规防治的相似系数依次0.6459、0.5829，保铃棉和冀抗668与常规不防治的相似系数为0.5669、0.4485.2002 年与冀杭668的相似系数最高(0 。6887)，保铃棉和冀抗668与常规防治相似系数为0.4739、 0.3828，保铃棉和冀抗668与常规不防治的相似系数为0.3124、0.3999，此结果表明，两转Bt 基因棉田节肢动物群落的整体结构一致，相似性较大，与常规防治相比，相似系数有所降低，表明常规功治棉田中人为控制因素对节肢动物有一定影响；转Bt基因棉对节肢动物群落有一定影响，但并不显著。

In order to reduce the energy of that part, three kinds of pressure drop reducing structures are devised and experimented together, such as the straight stick pressure drop reduction frame, grid pressure drop reduction frame and the taper pressure drop reduction frame.

本文设计并实验了三种不同类型的减阻结构：直杆减阻框、栅格减阻框和锥形减阻框以降低排气管内的流动阻力损失。

The results of pressure drop characteristics experiments indicate that the new type cyclone tube's pressure drop reduction extent is directly related to the sticks'number, length and the radial position of the straight stick pressure drop reduction frame; is directly related to the length, width and number of grid pressure drop reduction frame installed under the split flow core tube.

安装在排气芯管内的直杆减阻框、栅格减阻框使旋风管的压降有不同程度的降低，减阻幅度与直杆减阻框杆数和长度成正比；与直杆的径向位置大小成反比；与安装位置、绕流截面形状有一定的关系；并与栅格减阻框的长度、宽度和片数成反比。

Under the condition of the same materials of 600 grams, the biogas production of the treatment with 480 grams food waste inoculated with 120 grams inoculums(TS ratio 9.47 of food waste and inoculum) was 9359 mL which was larger than that of any other treatment significantly. The reduction effects of TS, VS and CODCr were also the best, and the reduction rate was 60%, 70% and 39.67%, respectively. However, there was no significant difference in CODCr reduction compared with CK which was not inoculated.
