通过对黄陵背斜周缘9条剖面奥陶纪和志留纪笔石反射率的研究,进一步证明笔石外皮具有明显的双轴和各向异性的光性特征。笔石外皮的反射率,类似镜质组和自然沥青,随成熟度的增加而增加。因此,在缺乏镜质组的前泥盆纪地层中可以利用笔石的反射率作为热成熟度的指示。根据所获笔石反射率资料的分析,可以将本区奥陶系和志留系划分为三个不同的成熟度区。其结果与牙形石色变指数(CAI)和干酪根红外光谱鉴定所提出的区域有机质成熟度分布模式基本一致。

2000年第五届国际天线、电波传播与电磁理论学术会议

作者： C. Zhang H. X. Zheng d. b. Ge(Physics department Ningxia University Yinchuan 750021 China Physics department Xidian University Xi’an 710071 China)

＜正＞ Making use of three dimensional （3-d） orthonormal bases of Haar wavelet function, a 3-d multiresolution analysis is derived. This procedure is similar to the finite difference time domain （FdTd） method. While the proposed technique is applied to a realistic microwave passive component, the computational time is reduced approximately by half compared to the FdTd method and the result agrees well with traditional FdTd method.

The 20th European biomass Conference and Exhibition

作者： Lamaudière,S. Godin,b. Agneessens,R. Schmit,T. Goffart,J.-P. Stilmant,d. delcarte,J. Gerin,P.A.

We analyzed herbaceous biomasses that have high contents of structural polysaccharides, reserve polyfructans and soluble sugars that can be converted by micro-organisms to ethanol. The present study examined the composition of Perennial ryegrass（Lollium perenne）, Hybrid ryegrass（***） and Italian ryegrass（L. multiforum）, investigated the influence of cultivar, development stage, harvest time in the day, and tedding on carbohydrate availability in the harvested biomass. This study also checked the suitability for a direct conversion of the soluble sugars of the analyzed grasses to ethanol. The results showed that S. cerevisae can produce ethanol directly from the green biomasses but the endogenous microbial flora is responsible for the production of lactic acid and other volatile fatty acids.

Renal Function after Major Uro-Oncologic Surgery and dexmedetomidine Infusion

Open Journal of Anesthesiology 2013年第8期3卷 356-362页

Objective: Acute kidney injury in major surgery is associated with increased postoperative mortality. This study aimed to evaluate renal function after major urologic surgery and intraoperative dexmedetomidine infusion. Methods: Thirty oncologic patients with normal renal function scheduled for prostatectomy or nephrectomy, anesthetized with combined epidural and general anesthesia, were randomized to receive either intraoperative blind infusion of dexmedetomidine (dexmedetomidine Group, n = 15, 0.5 μg/kg load dose plus 0.7 μg/kg/h) or 0.9% saline (Control Group, n = 15) until the end of surgery. Intraoperative and cumulative 24-hour diuresis, serum creatinine (SCr), calculated creatinine clearance (ClCr) and serum cystatin C (SCys) at postoperative days 1, 2 and 3 and 2 weeks after surgery were evaluated. Results: Mean ± standard deviation values for intraoperative diuresis in dexmedetomidine and Control Groups were 566 ± 396 mL and 298 ± 153 mL, respectively (p = 0.014). Cumulative 24-hour diuresis in dexmedetomidine and Control Groups was 1947 ± 266 mL and 1748 ± 237 mL, respectively (p = 0.91). Mean values of SCr, ClCr and SCys were not significantly different from their baseline values in both groups and no significant differences were seen between groups at any moment for two weeks (p > 0.05). Conclusion: According to the doses used in this study, despite an intraoperative increase in diuresis, intraoperative infusion of dexmedetomidine did not influence renal performance up to two weeks after major uro-oncologic surgery, as evaluated by SCr, ClCr and SCys.

膨胀石墨经硼氧化物浸渍修后辊轧制成柔性石墨箔。应用激光质谱、X-光电子谱、扫描电镜和热重测定分析了所制柔性石墨箔。结果表明:浸渍硼氧化物后石墨箔的初始氧化温度提高了约150℃。即使浸渍少量(质量分数低于2%)的硼氧化物也能提高此材料的拉伸强度。纵观其浸渍改善效果,可能归因于膨胀石墨粒中与石墨片层化学键合的硼氧化物堵塞了其活性位点所致。
