The burial history and thermal history of the outcrop are modelled firstly in China, and the organic matter maturity ro % of subsurface source rock is predicted by artificial changing burial trace.

本文在国内首次模拟了野外露头的埋藏史和地热史，并通过人工改变埋藏轨迹，预测了盆地内中侏罗统地下烃源岩的有机质成熟度。

In this paper, the organic geochemical characteristics of the hydrocarbon source rocks are described in detail in the light of the abundance, type and maturity of organic matter.

本文从有机质丰度、有机质类型及成熟度三方面对烃源岩有机地球化学特征做了详细分析。

Generation depends on three main factors: the presence of organic matter rich enough to yield hydrocarbons, adequate temperature, and sufficient time to bring the source rock to maturity.

生成作用取决于三个主要因素：有机质的存在丰富到足够产生烃类；适宜温度与足够的时间使源岩达到成熟。
