改良的

THE FIRST TOTAL SYNTHESIS OF TAXAMAIRIN B Taxamairin B, representive of rare naturally-occuring rearrang-ed 9(10→20)-abeo-8, 11, 13-triene diterpenoids, has been firstsynthesized by a eleven-step route in an overall yield of 8.19%,starting from commercially available catechol and 1,3-cyclohexan-dione. The improved Friedel-Crafts annulation, thermodynamicallycontrolled-geminal pairing methylation, the selective oxidation ofallyl group and the selective reduction of the less-hindrancecarbon-carbon double bond are the key steps.

二。美丽红豆杉素B的全合成研究 1，美丽红豆杉素B的首次全合成以价廉，易得的邻苯二酚和1，3-环己二酮为原料，经过改良的Friedel-Crafts烷基化反应，热力学控制的α，β-不饱和酮结构的α一位双烷基化，烯丙位的选择性氧化，以及选择性还原位阻较小的碳碳双键等十一步反应，以8.19％的总收率首次完成了美丽红豆杉素B的全合成。

During the processes of the soil improvement, concerning commix tier and noncommix tier of gypsum have different discriplinarian, which from quantitative change to qualitative change.

这8个化学方程，在石膏改良碱土中出现，并严重影响土壤改良进程，有时成为碱土改良成败的关键所在。

But the result of improvement soil translated alkaline soil into alkalier soil. Not onlu it is unavoidable and subsisted of stabilization in commix tier of gypsum, but also it destroyed direct improvement process. It is imported find what solved seepage problem of gypsum in the study. In configured duality structure of improvement soil, it needs abundance seepage gypsum in commix tier into noncommix tier in order to losing seepage capacity reduce in all deepness of improvement soil.

碱土改良过程中石膏渗漏损失最高可达到石膏施入量的40%以上，而改良结果碱土只转化为重碱化土；在石膏混合层内，它是一种不可避免的、稳定存在的且直接破坏土壤改良进程逆流；因此解决石膏渗漏问题亦是在本文研究工作中的重要发现：配置二元结构改良碱土中，正需要石膏混合层中大量石膏渗漏，以改良非石膏混合层，并使整个计划改良深度内的渗漏损失降为零。

For meeting the challenges, it adjusted theory and policy, to realize its innovation and rejuvenescence.

作为植根于资本主义生产方式的改良主义的一种社会政治思潮，民主社会主义奉行多元主义的指导思想，坚持多元化的社会政治经济模式，追求民主、自由、平等、公正、互助、人权等抽象的价值目标，主张通过渐进、改良的道路实现自己的目的，反对暴力革命和无产阶级专政，它坚持"全民党"的理论，否认党的阶级先锋队性质，主张建立一个向一切阶级、阶层敞开大门的群众性的党。

Method］from january 2003 to may 2006,32 patients were corrected with qin si-he's orthotics devices on the ilizarov principle of tension-stress,which involved 15 males and 17 females,the age ranged from 10 to 25 years.among these patients,2 were caused by peroneal nerve injury,l by tumor in the vertebral canal,5 by meningocele,11 were caused by poliomyelitis,13 by congenital talipes equino-varus.in accordance with deformities,external fixator and limitied operative methods were dertermined.the limited release of soft tissue were performed in 7 patients,limited osteotomy in 25 patients.the dynamic muscle balance operation were performed in 9 patients with imbalance of muscle strength.according to the ilizarov technique,the fixative rods were installed.the telescopic rods on the apparatus were rotated one week after the operation,the divices had corrective function in three-dimensional directions.the deformity of talipes equinovarus,internal rotation and drooping of the forefoot were gradually corrected,and the patients could bear weight and walked on the deformed foot.the mean duration of traction were 42 days,then removed the external fixator maintained with plaster for a site time.

The results showed: when TLC solvent system was: chloroform - methanol - diethyl amine = 90:9:1, alkaloids from lotus leaves were well isolated, and five components were isolated and identified by spraying Dragendorff reagent. The optimal conditions of HPLC solvent system were: methanol- water - diethyl amine = 75:25:0.0125. Under the conditions, components of alkaloids from lotus leaves were separated very well, and ideal RP-HPLC peaks were obtained.5、Methods of High Speed Counter Current Chromatography and preparative High Performance Liquid Chromatography applied to identify and purify alkaloids from lotus leaves were set up. When solvent system of HSCCC was: chloroform - methanol - water (pH=4.00)= 4:3:2, speed of chromatogram was 700rpm, flow speed of the mobile phase was 2mL/min, four pure components relatively were attained by isolation and purification.

The strainpath analysis indicates that the deformation of the sheet at the fracture location changes into the plane-strain mode from the stretch mode as the die corner radius is further increased from the optimum value, resulting in an early fracture since the plane-strain mode has a lower forming limit as shown in the FLD of Fig.
