In recent years, with the advanced requirements for speedup and heavy load from rail transport, the advanced requirements for the property of supporting pedestal have been proposed. The inherent defectivenesses which include the low mechanical property, low fatigue ductility and low shock resistance of cast-steel product, and the avoidless gas cavity, shrinkage porosity, inclusion, crack, etc in cast-steel product, existed in the product of Cast-steel supporting pedestal, have threatened the high speed and safe running of railroad.

近年来，随着铁路运输对重载、高速要求的提高，对关键部件支撑座的性能要求也在提高，铸钢支撑座产品存在的固有缺陷(铸钢件本身的机械性能、疲劳韧性、抗冲击性能都不高，铸件产品无法避免地存在气孔、缩松、夹杂、裂纹等)对铁路高速安全运行已构成威胁。

The biomarkers such as the n-Alkanes, the isoprenoids, the terpane, and cholestane were detected through GC-MS analysis. Based on the study of the biomarkers, the biological evolution during Permian and Triassic can be divided as three stages, namely, the mixing source stage of low biota such as thallose and advanced plant in late Permian (below bed 63), the stage of low biota such as thallose in the boundary transitional layer (bed 63-69) and the mixing source stage of advanced plant and low biota such as thallose in early Triassic (above bed 69). What's more, the second stage near the boundary transitional layer can be subdivided into 4 stages. The stages of biota evolution is close related with sedimentary environment changing and the boundary transitional layer.

利用GC—MS分析技术，在陆相地层中检测出正构烷烃、类异戊二烯烷烃、萜烷和甾烷类生物标志化合物并根据生物标志化合物和特征值研究，将二叠系—三叠系生物演化划分为三个大的阶段，即晚二叠世的菌藻类低等生物与高等植物混源阶段（63层以下），界线异常层的菌藻类低等生物阶段（63-69层）和早三叠世高等植物与菌藻类低等生物混源阶段（69层以上），界线附近异常层的第二阶段又进一步细分为4个次一级阶段，生物演化阶段与沉积环境变化及界线异常层具有非常密切关系。

Based on the problems of low viscosity index and the acidity increasing in the lubricating base oil,it has been found that the unstable quality of the crude oil was the root cause to effect on the quality of the base oil by analysis for long time;the low viscosity index and the higher acidity were resulted from the low paraffinicity and the high content of aromatics,cyclane.

针对润滑油基础油相继出现的黏度指数降低、酸值升高等问题，跟踪分析了润滑油基础油质量，认为原油的变化是造成润滑油基础油质量变化的根本原因；基础油组成中烷烃含量降低，芳烃和环烷烃含量上升是其酸值上升和黏度指数下降的内在原因。

Results The splenic infraction was showed triangular or unr egular low density regions which had no enhancement,Metastasis tumor of spleen had imaged cystiform low density single or several masses,The patho logicai presented little nodular or circle enhancement.Primary lymphoma of spleen had presented part range low density regions and uneven enhancement .
