此种方法由于扩口时的精度不高，现场施工环境和条件所限，很难达到预期的效果，加之操作复杂、石棉绳绝热作用的不充分性等引起的焊接高温很容易对钢管对接处的内涂层产生破坏，同时还引起热影响区金相组织发生变化、产生残余应力而引起应力腐蚀开裂，造成环氧粉末系列的内防腐钢管功亏一篑，实践证明不是最佳方案。

In this paper, the dynamic compressing experiments for the matrix material of the tungsten alloys which have been three different deforming(0%、 32.6%、 44.6%) processed have been performed by the experimental technology of separated Hopkinson pressure bar and many accurate datum have been obtained. Also the three materials have been compared with each other and analyzed. The results show that the optimized values are in a certain range to optimize the materials by changing their deforming technology. The parameters of constitutive model of Johnson-Cook have been fitted based on the datum. Then proceed to the next step, adiabatic shear band of these three matrix materials has been analyzed with finite element method. The result shows that the relations between stress and strain are different because of the differences of technical process of the three materials, but they are in great commonness in the material experiment and in great coherence in the distribution of time and space, which can been seen from the space distributing figures of plastic strain.

As temperature increased from 40 to 70℃, ferric reduction capacity of microorganism biocoenosis from Jilin, Tianjin and Hunan paddy soil were restrained to a certain extent. Adding AQDS could increase ferric reduction rate of microorganisms biocoenosis from Jilin, Tianjin and Sichuan paddy soil significantly. In axenic culture treatment of 6 kinds of bacterial strain experiments from Sichuan and Jiangxi paddy soil, a bacterial strain was suitable to 50℃.

于40~70℃升温处理后，来源于吉林、天津和湖南水稻土微生物群落的铁还原能力受到一定程度抑制；添加AQDS可显著增加来源于吉林、天津和四川水稻土的3种微生物群落的铁还原反应速率；在6株铁还原菌的纯培养试验中发现了1株更适于在50℃下生长的菌株。

After comparison of 30 and 50℃ treatments, AQDS were added into 3 kinds of microorganism biocoenosis from Jiling, Tianjin and Sichuan paddy soil, and it showed that AQDS could accelerate the reduction of Fe 10%-288%, meanwhile, temperature could accelerate the reduction of Fe 6%-17%. In axenic culture treatment of 6 kinds of bacterial strains from Sichuan and Jiangxi paddy soil, the maximum accumulation amount of Fe reduction rate was constant, the maximum reaction rate and ferric reduction rate of ferric strain JX-a08 all increased as temperature rose, which showed that bacterial strain JX-a08 were suitable to 50℃.

在30和50℃培养温度下，来源于吉林、天津和四川的3种水稻土微生物群落添加AQDS可使Fe还原的反应速率常数增加10%~288%，而温度变化的增加幅度仅为6%~17%；对分离自四川和江西水稻土中的6株铁还原菌的纯培养试验发现，菌株JX-a08的Fe最大累积量、还原速率常数、最大反应速率及铁还原率均随培养温度的升高明显增加，表明菌株JX-a08更适于在50℃下生长。

5 kinds of paddy soil treatments were studied, then each microorganism biocoenosis was extracted or bacterial strain was dissociated. Artificial synthesis ferric oxide was considered only electron acceptor, which inoculated soil leaching liquor or bacterial strain with reduction function in mineral salt culture system under anaerobic constant temperature condition. After different temperature treatments towards leaching liquor, temperature was controlled and AQDS added into culture system in order to discuss the effect of temperature and AQDS on ferric oxide microorganism reduction process.

Therefore, the structure could be stable. However, the structure was changed to amorphous when the strain level was over 15%. At the same time, the binding energy increased rapidly and the structure stability was reduced. During the deformation process, both the bond angle and bond length were significantly affected by the strain level.

这表明Ni纳米线的径向很软，结构之间几乎没有能量转换，且其稳定性基本不变；当压缩程度大于15%时，Ni纳米线结构变为无定形结构，它的结合能变大，且变化很快，表明其稳定性降低；压缩程度对Ni纳米线键角和键长的分布有着很大的影响。
