为研究550 kV/8000 A大容量SF_(6)充气套管的温升特性,建立了550 kV/8000 A大容量SF_(6)充气套管多物理场耦合模型,利用ANSYS软件,综合考虑涡流效应、集肤效应、重力作用、热对流、热辐射等因素,计算分析了1.1倍额定电流(8000 A),即8800 A电流条件下套管的温度场与气流场分布规律,并进行了550 kV/8000 A SF_(6)充气套管的温升试验,验证了仿真结果的正确性。最后仿真分析了外部风速、气体压强、负载电流、中心导体外径等4种影响因素对套管温升特性的影响。研究结果表明:最高温度位于套管内中心导体上部的小孔下方,最高温度为363 K,从整体角度看,套管上方的温度高于下方;仿真结果与试验结果一致性较好,误差在8%以内;套管的温升随外部风速的增大明显降低,但降幅逐渐减小;套管的温升随着气体压强的增大而降低;电流越大,产生的焦耳热越多,负载电流直接影响导体温升;套管的温升随着中心导体外径的减小而增大。研究内容为大容量高压SF_(6)充气套管的设计工作提供了理论借鉴。

西湖凹陷西次凹古近系花港组和平湖组深层油气资源丰富,是东海陆架盆地勘探开发新领域,受储层差异致密化影响,油气成藏机理复杂。为了厘清西次凹深层油气成藏过程,本文通过流体包裹体岩相学特征、显微测温、激光拉曼光谱、包裹体所含油气地球化学等实验分析,结合构造演化、地层埋藏史、热史等,开展了系统的储层特征、油气成藏期次、成藏过程研究。结果表明,花港组深层(>4000 m)和平湖组储层均已致密化,溶蚀孔隙是主要的储集孔隙类型;花港组和平湖组均发育两期油气包裹体,早期含油包裹体较多,晚期以天然气包裹体为主,成藏时间分别为龙井运动期和冲绳运动期,以晚期天然气成藏最为关键。包裹体中油气地球化学特征类似,反映生烃母质以高等植物生源为主,低等生物为辅,与平湖组煤系烃源岩特征一致。冲绳运动叠加平湖组生气增压是晚期天然气成藏的主要动力,此时H10段及以上储层未致密化。根据储层致密化与成藏时序匹配关系可将西次凹M构造深层油气藏类型划分为常规型、先成藏后致密型、先致密后成藏型和边成藏边致密型4种。本文成果可为研究区下一步致密砂岩气的勘探开发部署提供重要的理论依据。

The peridotite xenoliths are widely distributed in the Cenozoic basalts, Eastern China. However, their petrogenesis is hotly controversial. The peridotite xenoliths of Nanjing are found embedded in Cenozoic alkali basalt. Most of the xenoliths are rounded and small to moderate in size(typically 5~10 cm in diameter), though larger ones have been found. Nearly all small xenoliths are harzburgite and dunite. However, the big ones have zoned structure: lherzolite core and harzburgite or dunite rim with new growth clinopyroxene(Cpx) as eyeliner along their margins. Petrology, mineralogy, and Major and trace element compositions of the Nanjing peridotite xenoliths in the Cenozoic basalts are measured to provide an insight into the nature of their mantle sources and processes. Our works suggest that they were suffered from a partial melting process and subsequently underwent a process of melt-peridotite interaction. The evidences of partial melting are as follows. Firstly, the lherzolite core is mostly composed of olivine(Ol) + orthopyroxene(Opx) + Cpx with minor spinel(Spl), however, the harzburgite or dunite rim is mostly complosed of Ol + Opx with minor Cpx. Secondly, from the lherzolite core to the harzburgite or dunite rim, Ol and Opx contents are gradually increased, inversely, Cpx contents are decreased, and the Spl disappears. Thirdly, Mg# values of Ol are increased from the core(~89.5) to the rim(>92) of the peridotite xenolith, but FeO contents(from 11.0 to 8.1) in Ol are ***, Mg#(from 90 to 93) and Cr#(from 4 to 17) values of the Opx are increased, but its Al2O3 contents(from 5.0 to 2.0) are decreased from the core to the rim. The evidences of meltperidotite interaction are mostly from clinopyroxenes. The clinopyroxenes can roughly divided into two groups: original clinopyroxenes of the peridotite and new growth clinopyroxenes generated by melt-peridotite interaction. The original clinopyroxenes are generally in the inner of peridotite xenoliths suc

AIM: To investigate the early diagnostic methods of bacterial and fungal infection in patients with chronic cholestatic hepatitis ***: One hundred and one adult in-patients with chronic hepatitis B were studied and divided into 3 groups:direct bilirubin (DBil)/total bilirubin (TBil)≥0.5, without bacterial and fungal infection (group A, n=-38); DBil/TBil<0.5, without bacterial and fungal infection (group B, n=23),DBil/TBil≥0.5, with bacterial or fungal infection (group C,rr=-40). The serum biochemical index and pulse rate were ***: Level of TBil, DBil, alkaline phosphatase (ALP) and DBiI/ALP in group A increased compared with that in group B. The level of ALP in group C decreased compared with that in group A, whereas the level of TBil, DBil and DBiI/ALP increased (ALP: 156+43, 199+68, respectively,P<0.05, TBil: 370+227, 220+206, respectively, P<0.01,DBil: 214+143, 146+136, respectively, P<0.01, DBiI/ALP:1.65+1.05, 0.78+0.70, respectively, P<0.001). The level of DBil and infection affected DBiI/ALP. Independent of theeffect of DBil, infection caused DBiI/ALP to rise (P<0.05).The pulse rate in group A decreased compared with that in group B (63.7+6.4, 77.7+11.4, respectively, P<0.001),and the pulse rate in group C increased compared withthat in group A (81.2+12.2, 63.7+6.4, respectively, P<0.001).The equation (infection=0.218 pusle rate +1.064 DBiI/ALP-16.361), with total accuracy of 85.5%, was obtained from stepwise logistic regression. Pulse rate (≥80/min) andDBiI/ALP (≥1.0) were used to screen infection. The sensitivity was 62.5% and 64.7% respectively, and the specificity was 100% and 82.8% ***: Bacterial and fungal infection deterioratejaundice and increase pulse rate, decrease serum ALP andincrease DBiI/ALP. Pulse rate, DBiI/ALP and the equation(infection=0.218 pusle rate+1.064 DBil/ALP-16.361) arehelpful to early diagnosis of bacterial and fungal infectionin patients with chronic cholestatic hepatitis B.

A构造位于西湖凹陷中北部,花港组H3砂层组为主力目的层,其储层横向分布相对稳定,但储层砂体厚度大,非均质性强,骨架河道的雕刻不清制约了优质储层的预测。利用灰色理论,定量计算西湖凹陷A构造花港组隔夹层综合评价指标IRE,识别厚层砂岩中的隔夹层类型,划分河道期次,识别骨架河道。此外,计算河道宽厚比和砂地比,半定量表征河道连通性及展布特征,预测优质储层发育区。结果表明,西湖凹陷A构造花港组发育两种类型隔夹层:落淤层夹层和泥岩层隔层,其中落淤层IRE值为24~45,泥岩层IRE值为51~110,在H3砂层组识别出3大套共10期单河道砂体。工区单河道宽厚比为38.87,折算出各期河道展布范围为1.1~2.3 km,河道砂体几乎都呈叠拼式展布。在地震复合微相指导下,对花港组早期河道进行识别和追踪,结合沉积微相、粗粒相带及成岩相分布特征,认为A构造南部有利储层更为发育。

威海地区出露古元古代泥质麻粒岩,其构造属性仍存在争议.泥质麻粒岩以透镜体的形式出露在花岗质片麻岩中,透镜体从核部到边部的岩性逐渐变化:未变形的粗粒泥质麻粒岩、面理化的细粒泥质麻粒岩、石榴黑云片麻岩和混合岩化麻粒岩.粗粒泥质麻粒岩,粗粒斑状变晶结构,块状构造;细粒泥质麻粒岩,细粒斑状变晶结构,面理发育;石榴黑云片麻岩,斑状变晶结构,片麻状构造,上述3种岩石的主要矿物组合均为石榴子石+黑云母+斜长石(反条纹长石)+石英+矽线石;混合岩,条带状构造,暗色残余体主要矿物组合为石榴子石+斜长石+黑云母+石英+矽线石,浅色体矿物组合为石英+斜长石+钾长石.所有样品均有金红石、锆石和独居石等副矿物.粗粒泥质麻粒岩中的锆石颗粒均为浑圆近等粒,具有典型的麻粒岩相变质锆石的特征:锆石CL图像为均一的云雾状或补丁状结构,低的Th/U比值(0.01~0.30),强烈的Ce正异常和Eu负异常,HREE的亏损及高的Hf/Y比值(19~537).利用锆石Ti温度计获得的变质温度为788~892℃(加权平均值为837±24℃).锆石U-Pb定年获得上交点年龄为1863±18 Ma,206Pb/238U加权平均年龄为1832±23 Ma.εHf(t)值为-3.4~-4.9(加权平均值为-4.23±0.35),相应的两阶段模式年龄(TDM2)为2716±107 Ma~2807±93 Ma(加权平均值为2767±44 Ma).细粒泥质麻粒岩中的锆石也具有麻粒岩相锆石的CL和微量元素特征,Ti含量温度计获得的变质温度为804~909℃(加权平均值为845±23℃),锆石U-Pb上交点年龄为1823±14 Ma,谐和206Pb/238U年龄加权平均值为1812±13 Ma,εHf(t)为-3.7~-5.7(加权平均值为-4.67±0.37),TDM2为2705±133 Ma~2826±116 Ma(加权平均值为2766±46 Ma).石榴黑云片麻岩中的锆石也具有麻粒岩相变质锆石的CL和微量元素特征,锆石Ti含量计算变质温度为785~923℃(加权平均值为820±32℃),锆石U-Pb上交点年龄为1807±22 Ma,εHf(t)为-4.5~-9.0(加权平均值为-6.07±0.48),TDM2为2742±90 Ma~3020±92 Ma(加权平均值为2839±41 Ma).混合岩中的锆石大部分具有核-边结构.根据Ti含量温度计获得的混合岩中麻粒岩相变质锆石核的变质温度为754~875℃(加权平均值为818±30℃),U-Pb上交点年龄为1822±19 Ma,εHf(t)值为-4.3~-6.3(加权平均值为-5.47±0.35),TDM2为2742±82 Ma~2864±91 Ma(加权平均值为2814±43 Ma).可见,麻粒岩、石榴黑云片麻岩和混合岩经历了相同的麻粒岩相峰期变质作用(~1.8 Ga),具有相同的原岩属性,即晚太古代(2.7~2.8 Ga)的地壳物质.麻粒岩透镜体从核部到边部岩性的变化,可能受到晚三叠纪碰撞造山作用的不同程度改造.因此,威海超高压地体中出露的泥质麻粒岩透镜体,在构造亲属性上可能属于华北克拉通地壳物质,成因上可能与哥伦比亚超大陆的演化有关,在三叠纪大陆俯冲碰撞过程中卷入造山带.

Polycystic ovary syndrome （PCOS） is a comprehensive syndrome with clinical features of low menstruation or amenorrhea, obesity, crinosity, and infertility as a result of endocrine disturbance and metabolic disorder [1]. Its pathomechanism is extremely complex, e.g., heredity, internal secretion, immunity, and metabolism. Furthermore, it is considered as the important dangerous factors of many serious diseases such as type 2 diabetes, cardiovascular diseases, hypertension syndrome of pregnancy and endometrial carcinoma, which make it go beyond the range of gynecology and raise the attention worldwide.
