The results show that the active loss of heteropolyacid catalyst are mainly attributed to the reduction of surface area, coke formation, and reduction of acid strength during the long term of operation for isoamylene unit. The improvement aspects of the catalyst performance for the decomposition of TAME are proposed.

结果表明，在长周期运行中，催化剂比表面下降、结焦和酸性的损失是导致催化剂活性降低的主要原因，最后提出了TAME裂解催化剂的改进方向。

The oxido-reduction and reduction-reoxidation specificity of heteropolyacid salts containing various kinds of alkali metals used for one-step oxidition of isobutyraldehyde to produce methacrolic acid was studied by ESR method.

用ESR法研究了异丁醛一步氧化制甲基丙烯酸过程中所用杂多酸盐催化剂的氧化－还原特性。

F. On the other hand, as the gas with high oxidizability introduced to pre-reduction process, it will give a lower reductibility of iron ore and as the ore come to the final process the burden of the final reduction vessel will be heavier, the refractories of it will be corroded seriously and the campaign-life of it will be shorter.

终还原排出的煤气可以供预还原使用，由于排出煤气温度较高，需要降温才能供预还原炉使用，在此过程中煤气的物理热未被利用，这是目前熔融还原工艺能源消耗普遍大于高炉工艺能源消耗的主要原因；同时排出煤气氧化度较高，影响到矿石的预还原率较低，铁浴终还原的负担较重，终还原炉渣对炉衬的侵蚀严重，影响到铁浴终还原炉的寿命。

The key steps were Stetter reaction, regioselective reduction, substitute controlled asymmetric reduction and Paal Knoor reaction.

该方法不仅避开了专利方法，而且高效、原料便宜易得、成本低，具有很大的应用前景。

Methods:Fifty-six patients with metacarpal and phalangeal fractures who were reviewed in the study were divided into two groups:Group A and Group B.Thirty-two patients in Group A were treated with open reduction,Kirschner internal fixation and postoperative plaster splint external fixation.Other 24 patients in Group B were treated with open reduction,Mini-plate internal fixation,without any external fixation.

回顾分析经完整随访的56例掌指骨骨折患者的治疗和康复情况，A组：32例掌指骨骨折患者予以行切开复位交叉克氏针内固定接骨术，术后石膏夹板外固定；B组：24例掌指骨骨折患者予以行切开复位微型接骨板内固定接骨术，术后未用外固定。

Starting from chiral proline, pipecolinic acid, piperazine-2-carboxylic acid and 1,2-diphenyl amino alcohol, a series of structurally simple and easily prepared amides were developed as highly effective Lewis basic organocatalysts for the asymmetric reduction of imines with trichlorosilane as the reducing agent, which promoted the reduction of N-aryl imines with high yields and excellent enantioselectivities with an unprecedented substrate spectrum.

本文分别由手性脯氨酸、哌啶酸、哌嗪酸以及氨基醇出发，设计和合成了一系列结构新颖、合成简便、性能优良的酰胺类有机小分子路易斯碱催化剂，以廉价的三氯氢硅为氢源，用这些催化剂催化亚胺不对称还原，得到了非常优良的收率、对映选择性和前所未有的底物普适性。

The prevertebral heights increase is not unlimited between different reduction process of L1 fracture, and it is limited by spinal anatomy on the late phase of reduction. Knowing these features is useful for us to treat the patients and improve the devices.

L1骨折后在不同复位方式的复位过程中椎前高度不是无限制的增加，复位后期椎前高度都明显受到脊柱解剖结构的制约，因此在临床治疗或器械改进时，充分了解这些特点非常有益。
