确定了分离纯化SAM的最优条件是：在pH值5.0时，含SAM浓度为3.0 g/L的上柱液，以6 L/h的流速，过装填D152树脂的离子交换柱(φ50 mm×1500 mm)后以去离子水和醋酸洗脱除杂，再用9 L到15 L浓度为50 mmol/L的硫酸以6 L/h的流速洗脱，可以分离得到纯度较高的SAM粗品。

The water body is usually in the flowing state, the atmosphere oxygen resume includes the molecule diffuseness and turbulence diffuseness. Especially in the slowly flowing water, such as the reservoir and the backwater river, the velocity has only the 10〓m/s level, it is necessary to consider both kind of diffuseness.

下降环腔流速使低安注流速时的安注影响的范围局限于下降环腔下游的细长区域。

The bigger top tension will cause the wellhead to be over-pulled and increase the probability of wellhead collapse. As the mean drifting of drilling vessel or platform increases, the wellhead displacement and bending moment nearly linear enlarges. The greater current velocity may result in wellhead instability because of its limited bearing moment capacity. Therefore the drifting control is very important to subsea wellhead stability. The wellhead stability may be improved by taking measures such as enhancing the conductor bending strength, controlling scour depth on seabed, getting geological data sampling of shallow formations.

算例分析表明，水下井口的横向偏移及弯矩随张力比和海流流速的增加而大幅增大，顶张力过大会引起井口稳定性变差；随着钻井船或平台漂移量的增加，井口的横向偏移和弯矩近似线性增加，控制好钻井船或平台的漂移非常重要；由于井口承受弯矩的能力有限，较大海流流速情况下可能造成井口失稳；提高导管抗弯强度、控制泥线处管柱冲刷、获取浅部地层的取样数据等措施可以增强井口稳定性。

The solids mass flux in the riser is maintained by controlling the liquid flow rate through the eductor (which was precalibrated for solids flow rate as a function of motive water flow rate).

Firstly, the natural frequencies and normal mode shapes of the fluid-conveying pipe with zero fluid velocity (i.e. U=0) were determined with the transfer matrix method. Next, these natural frequencies and normal mode shapes were used to derive the equation of motion for the fluid-conveying pipe with fluid velocity U.neq.0 by using the expansion theorem. Finally, the free and forced vibration responses of the pipe with flowing fluid were obtained by means of the Jacobi method and the Newmark direct integration method.
