According to common evaluation method of source rocks, the Meishan Formation has been assigned to nonhydrocarbon source rock because of its low organic abundance (<0.5%) and a Ⅲ-type kerogen. However, its hydrocarbon yield is as high as 71 mgHC/gTOC on average. Based on studies of biomarker and organic petrography, it is believed that the soluble organic matter of low maturity mainly consists of resin compounds which determine hydrocarbon generation of the formation. As a result, the formation could be considered a good to excellent hydrocarbon source rock.

目的 神经干细胞用于神经学临床修复和基础理论研究的前提是首先完成神经干细胞的体外分离、培养、纯化并大量扩增。鼠、人、猪中都已成功分离出神经干细胞并已尝试用于动物神经系统损伤等疾病的治疗，尽管在鼠和人上的研究很多，相对于鼠神经干细胞在神经学临床应用上的局限和人神经干细胞在材料来源上的不便，猪作为神经干细胞临床应用和基础研究的模式动物有很大的潜力。但关于猪神经于细胞体外分离培养的研究非常少，本文对这方
