苔藓植物含硫量与大气SO_2间对应关系的应用研究

本文通过对贵阳市区１３个采样点和大气监测采样分析，确认苔藓植物移植挂片含Ｓ量与大气中ＳＯ２浓度密切相关。环境在ＳＯ２污染状况下，以苔藓含Ｓ量的为因变量，环境中ＳＯ２浓度为自变量的线性回归方程，可以很好地测算大气ＳＯ２浓度，并评价大气污染等级。     

基于毛管数插值的二元驱油藏模拟方法

研究化学采油聚合物-表面活性剂二元复合驱中的毛管数曲线和相渗曲线。以毛管数与残余油关系实验曲线为基础完善了毛管数曲线数学表达式和以毛管数值为变量复合驱相渗透曲线的数学表达式,并成功用于化学驱油模拟软件中。 经算例测试表明,采用新的毛管数曲线表达式和相渗曲线表达式的数值模拟更能反映复合驱采油机理和规律,适应现代采油技术的需求。

Acetalization of Poly（vinyl alcohol） /Soybean Protein Fibers

Acetalizatioin on the blend fibers of poly （vinyl alcohol） （PVA） and soybean protein （SP） was studied by using dialdehydes as cross-linking agents. The optimal acetalization conditions were determined by Latin square experiment, where the modified fibers with good mechanical properties can be achieved by treating in 41 g/L dialdehyde solution at 67 ℃ for 9 min. The cross-linking reactions of PVA and SP with dialdehydes were confirmed by Fourier transform infrared （FTIR） spectroscopy. Tensile test and boiling water shrinkage measurements showed that the physical properties of PVA/SP fibers crosslinked by dialdehydes were improved comparing with those formalized fibers.     

Video-assisted thoracoscopic surgery （VATS） for bilateral primary spontaneous pneumothorax

Objective： To review our experience of the treatment of bilateral primary spontaneous pneumothorax （PSP） by video-assisted thoracoscopic surgery （VATS）. Materials and methods： Retrospective chart review was followed by an on-clinic or telephone interview. Patients were cared for by one thoracic surgeon in four medical centers or community hospitals in Northern and Central Taiwan. Thirteen patients with bilateral PSP underwent bilateral VATS simultaneously or sequentially from July 1994 to December 2005. Results： Twelve males and one female, with age ranging from 15 to 36 years （mean 23.1 years）, were treated with VATS for bilateral PSP, under the indications of bilateral pneumothoracis simultaneously （n=4） or sequentially （n=9）. The interval between the first and second contra-lateral VATS procedure for non-simultaneous PSP patients ranged from 7 d to 6 years. Eleven of 13 patients （84.6%） had prominent pulmonary bullae/blebs, and underwent bullae resection with mechanical or chemical pleurodesis. The mean operative time was （45.6±18.3） min （range 25-96 min） and （120.6±28.7） min （range 84-166 min） respectively for the non-simultaneous （second VATS for the recurrence of contralateral side after first VATS） and simultaneous （bilateral VATS in one operation） procedures. There was no postoperative mortality. However, prolonged air leakage （〉7 d） occurred in one patient （7.7%） who recovered after conservative treatment. The mean duration of chest tube drainage was 3.1 d and the median follow up period was 3.4 years. Conclusions： VATS is a safe and effective procedure in the treatment of bilateral PSP. Bilateral VATS is only recommended for patients with simultaneously bilateral PSP, because the incidence of recurrence, even with visible bullae, was not so high in my group and in some previous literature. Bilateral VATS in a supine position should only be used in selective cases, because of possible pleural adhesion or hidden bullae on the posterior si
