By formulating the apparent porosity cross calibration model of these two logs, and adopting the same matrix logging pa rameters as those of the practical complex lithology, the study constructs new log curves, utilizes and amplifies the different responses of neutron and density logs, eliminates multiple solutions caused by inaccurate calibration lithology, makes the overlayed curves take the same units, greatly improves the gas-i dentification resolution of this combination, intensifies the visual effect of gas indication.

从而能够放大中子、密度测井对地层中天然气的不同响应，消除刻度岩性不准确产生的多解性，统一重叠曲线的量纲，大大提高这两种测井组合识别气层的分辨率，增强气层指示的直观性。

In our view, this phrase is straightforward and means that Article 2.2.2 gives the specific instructions as to how to fulfil the basic but unelaborated requirement in Article 2.2 to use no more than a 'reasonable' amount for profit.

我们认为，这一表达是直接了当的并意味着条款2.2.2对于怎样去实现这个基础给出了详细的指示，但在条款2.2中没有关于如何去规定一个 '合理的'利润量。

However, the ratio of the unsaturated and saturated fatty acid amide is relatively stable in downcore indicating that there is no selectivity between those two types of fatty acid amides during diagenesis processes, including biological, chemical and physical degradation. For this reason, we suggested that the depositional environment in Qarhan paleolake was relatively aerobic during the organic component deposition.

另一方面，不饱和脂肪酸酰胺与饱和脂肪酸酰胺的相对量的比值在剖面上并没有呈现明显下降的趋势，说明各种生物、物理及化学作用对饱和与不饱和脂肪酸酰胺的降解过程不存在明显的选择性，指示了有机质在沉积过程中处于一个偏氧化的环境。
