Analysis on sedimentary cycles is very important in the academic study of stratigraphy, petroleum exploration and exploitation.

沉积旋回性分析在地层学理论研究和石油勘探开发中有着重要的地位。

Cyclostratigraphy was born in 1980s as a subdiscipline of stratigraphy. Based on the Milankovitch theory, outcrop sections and cores are analyzed with methods such as geochemistry, spectrum analysis, and time-sequence analysis to study the complex responses of orbital forcing to sedimentary records.

旋回地层学作为一门独立的地层分支学科诞生于20世纪80年代，它以米兰科维奇天文轨道旋回为理论基础，以露头剖面、岩心等为研究对象，应用地球化学、光谱分析和时间序列分析等方法，研究天文轨道参数周期性变化在地层记录中的沉积响应。

Methods: The osteoporosis model was made by male unsex rats and ANFD model was made by bipedal rats. The following indexes were observed: bone mineral density, bone metrology, fatty deposition in femoral head, blood capillary distrubution and other related biochemical indicators.

采用去势大鼠骨质疏松模型和二腿大鼠股骨头缺血性坏死模型，分别进行了骨密度、骨计量学、股骨头脂肪沉积、股骨头毛细血管分布和相关生化指标测试等试验研究。

The GEOTOP centre develops multi-disciplinary projects such as the study of uranium-thorium-radon desequilibrium in volcanology or the study of isotopic tracers at the water-sediment interface and internal process of the earth.

此中心开展了多学科的研究项目，如火山学中铀-钍-氡消除平衡的作用研究、水沉积物分界面的同位素示踪剂研究，以及地球内部作用的研究。

Sample collection: Two hundred and fifteen sera samples of normal population were collected from the peripheral blood of healthy blood donors of Shenyang, and the sera were separated by centrifugation after blood clotting; The patients sera were collected from the outpatients and inpatients of No. 1 hospital of China Medical University and the Second hospital of Jilin University. Syphilis was confirmed by clinical and serum test of TPHA and RPR; That of pemphigus vulgarism was confirmed not only by clinical, histopathological examination, but also by direct and indirect immunofluorescence test. DIF test on lesion or non-lesion skin showed immunoglobin and/or C3 deposits in the intercellular space of epidermis, and IIF test showed positive anti- intercellular antibody in patient serum using mouse's or rat's tongue or esophagus as substrate.

标本的收集：正常人的血清：采集沈阳市正常献血员外周静脉血共215份，待血凝后离心分离血清；患者的血清：来自中国医科大学一院及吉林大学二院门诊及住院部的病人，梅毒患者除了病史及临床表现外，全部经血清学TPHA及RPR确认；寻常性天疱疮患者除了临床及组织病理诊断外，还进行了直间接免疫荧光的检测，直接免诊断疫荧光：在皮损区及非皮损区的表皮细胞间显示IgG和/或C3补体沉积；间接免疫荧光用鼠或兔的舌或食管作为底物，在病人的血清中显示有肯定的细胞间抗体。

Three short geomagnetic excursions, the Go thenburg, Mono Lake and Mungo in the Brunhes Positive Polarity period, were revealed based on the studies of magnetostratigraphy, susceptibility and δ^18O of sediments in core WP 92-5 from the central temperature area of the Western Pacific Warm Pool, and the ages of them are 12.1--11.3 kaBP, 25.0--24.0 kaBP, and 31.0--28.0 kaBP respectively. Furthermore, the Younger Dryas and Heinrich cold events were also discovered in this core by the susceptibility record.
