Lipase‐catalyzed dynamic kinetic resolution of (R,S)‐fenoprofen thioester in isooctane

A lipase‐catalyzed enantioselective hydrolysis process under in situ racemization of the remaining (R)‐thioetser substrate with trioctylamine as the catalyst was developed for the production of (S)‐fenoprofen from (R,S)‐fenoprofen 2,2,2‐trifluoroethyl thioester in isooctane. Detailed investigations of trioctylamine concentration on the enzyme activation and the kinetic behavior of the thioester in racemization and enzymatic reactions were conducted, in which good agreement between the experimental data and theoretical results was observed. © 2002 Society of Chemical Industry     

稠油油藏的注汽量预测

利用HCZ预测模型，可对已开发油田的年产量和累计产量进行全程预测，并且在实际应用中取得了较好的预测结果。本文结合稠油田的实际情况，推导出HXZ预测模型在热采中注汽参数的预测公式。结合曙光油田曙1－7－5块的开发数据进行了预测，效果较好。

Ion implantation doping of OMCVD grown GaN

Doping by ion implantation using Si, O, Mg, and Ca has been studied in single crystal semi-insulating and n-type GaN grown on a-sapphire substrates. The n-and p-type dopants used in this study are Si and O; Mg and Ca, respectively. Room temperature activation of Si and O donors has been achieved after 1150°C annealing for 120 s. The activation of Mg and Ca acceptors is too low to measure at both room temperature and 300°C. Using higher doses to achieve a measurable p-type conduction increases the amount of damage created by the implantation. Rutherford back scattering measurements on this material indicate that the damage is still present even after the maximum possible heat treatment. Secondary ion mass spectrometry measurements have indicated a redistribution in the measured profiles of Mg due to annealing.     

非对称单筒双井技术在文昌13-2油田的应用

南海西部文昌13-2油田目前共有开发井12口,油田已经没有空井槽,为充分开发油田,提高采收率,确定在文昌13-2油田A平台内挂4个?762 mm井槽,采用单筒双井技术,利用平台125t修井机,在?762 mm隔水管内下入?339.7 mm套管和?244.5mm套管,并利用?339.7 mm套管进行单筒双井的固井作业,实现了在同一井槽内完成2口不同井身结构的水平井钻完井作业。以同一槽口A16h井和A17h井为例,介绍了非对称单筒双井钻井程序、工艺特点以及钻井期间注意事项。单筒双井技术在文昌13-2平台成功的应用,充分地利用了井口平台的空间,减少了工程造价,降低了开发成本,摸索出了一套成功经验。

CALCULATION ON TWO-PHASE FLOW TRANSIENTS AND THEIR EXPERIMENTAL RESEARCH

From basic equations of gas-liquid, solid-liquid, solid-gas two-phase flow, the calculating method on flow transients of two-phase flow is developed by means of characteristic method. As one example, a gas-liquid flow transient is calculated and it agrees well with the experimental result. It is shown that the method is satisfactory for engineering demand.
