曲流河点坝内部构型的嵌入式建模方法研究

针对曲流河点坝厚砂体内储层非均质性表征,提出一种点坝内部构型的嵌入式建模方法。该方法以点坝级次三维模型及点坝内部构型分析结果为基础,依次通过基于三维向量场的侧积面模式拟合、侧积面趋势控制的侧积层厚度插值以及网格局部加密的侧积层模型嵌入等3个主要技术环节,形成一套完整的嵌入式构型建模技术流程及算法实现,并应用孤岛油田某区块曲流河点坝储层内部构型的三维建模实例,对建模方法的有效性进行验证。结果表明:嵌入式构型建模方法可建立与井点条件化的点坝内部侧积夹层精细三维模型,并可对井间侧积层分布进行有效预测;采用的网格局部加密侧积层模型嵌入方式优化了不同构型级次及尺寸规模构型单元的三维网格表示。

Association Between Genital Ulcer Disease and HIV Seroprevalence among STD Patients in Guangzhou

Objectives: To understand genital ulcer disease(GUD) among patients attending sexually transmitteddisease (STD) clinics in Guangzhou, China, and itsassociation with HIV infection.Methods: Between September 9th, 1997 and Octo-ber 30th, 2002, 8 962 patients with STDs wereevaluated. 285 patients were diagnosed with GUD basedon clinical manifestations and microbiologic evalua-tions including dark field microscopy and serologytest for syphilis (RPR, TPPA). Swabs of each genitalulcer were processed in a multiplex PCR assay (M-PCR) for simultaneous detection of Herpes simplexvirus (HSV), Treponema pallium, and Haemophilusducreyi. Other STDs were classified by routine diag-nostic criteria, including microscopy or culture forNeisseria gonorrhoeae, Chlamydia trachomatis,Urea- plasma urealyticum, Human papillomavirus,Trichomonas, etc.Results: Of the 8 962 patients with STDs, the HIVseroprevalence in patients with and without GUD was1.75% (5/285) and 1.53% (133/8677), respectively,with no statistically significant difference (χ 2=0.09,P>0.05; OR=1.15, 95%CI=0.47-2.81) . HIVseroprevalence in patients with syphilis, genital her-pes and other STDs was 2.81% (22/784), 0.74% (6/814) and 1.49% (110/7 364), respectively. Prevalencein patients with syphilis was significantly higher thanthat in patients with genital herpes and other STDs,(χ 2=9.92, P<0.005, OR=3.89, 95%CI=1.67-9.05;χ 2=7.66, P<0.001, OR=1.90, 95%CI=1.21-3.00).Conclusions: The study shows that the HIV sero-prevalence in this population of patients with GUDis very low. The results also indicate an associationbetween syphilis and HIV infection. The relationshipbetween genital herpes and HIV infection needsfurther research.

Results: The standard strains of T pallidum, HSV and Hducreyi were amplified by M-PCR, producing amplifiedproducts of 260bp,432bp,170bp, respectively. The sensitivityof M-PCR is 10~2 pg DNA. M-PCR assay for T.pallidum, HSVand H ducreyi showed good agreement en compared with D-F detection for T pallidum, STS, H ducreyi culture and EIAfor HSV antigen (Kappa scores are 0.774,0.704,0.793,0.756,respectively). Conclusions: The M-PCR is a convenient, accurate andreliable assay for the detection of T pallidum, HSV and Hducreyi from genital ulcers, and can be used as a method ofdiagnosing the etiology of GUD.

对流扩散方程的三阶迎风格式的数值摄动高精度重构

利用高智提出的数值摄动算法,把求解对流扩散方程常用三阶迎风格式(3-UDS)(粘性项和对流项分别用二阶中心格式和3-UDS离散)进行了高精度重构,包括使用离散单元内所有节点的全域重构和分别使用上下游节点的上下游重构,得到两类新的更高阶精度迎风差分格式,称为高的迎风差分格式(记作GUDS)。讨论了GUDS的数学性质,GUDS比原来的3-UDS精度显著提高;全域重构的GUDS和3-UDS均为条件稳定,一些上下游重构GUDS为绝对稳定。本文通过稳定性分析和四个算例(一维常系数、变系数、非线性及二维变系数对流扩散方程)的计算证实了GUDS的优良性质。上下游重构GUDS为避免在3-UDS中使用人工粘性提供了一条有效途径,适合于求解高Reynolds数线性和非线性问题。
