通过构造演化特征分析了海相烃源岩的发育，中、下扬子区中－古生代经历了加里东和海西－早印支旋回两个阶段的海相被动大陆边缘和克拉通盆地演化，形成了岩性稳定的巨厚中－古生界，发育了6套烃源岩，具有较强的生烃能力。

In chapter 5, using the method of the spectral theory of operators, we consider condition under which the infimum A∧B exists for two quantum effects A and B.

第五章用算子谱理论的方法和算子分块技巧，研究了Hilbert空间上两个效应的下确界问题。

Finally, the infimum is acquired of Hausdorff dimensions of its polar sets by means of constructing a Cantor-type set to connect Hausdorff dimension and capacity.

同时通过一个特殊的Cantor型集的构造将维数与容度巧妙地结合起来，得到了广义Brownian Sheet极集的Hausdorff维数的下确界。

We prove upward density ofpairs of intervals without infimum in the r.e.wtt-degrees.

我们证明了在wtt-度中两区间无下确界的向上稠密性，改进了Downey和Stob的一个结果。

For delay discrete-time linear system, saturant function is introduced. Thesufficient condition of GAS and RAS is presented by saturant function infimum.

针对时滞离散线性系统，引入饱和函数，利用饱和函数的下确界，建立了系统全局渐近稳定和局部渐近稳定的充分条件。

The LTR of centralized multivariable control systems is then generalized to decentralized control large-scale interconnected systems by H∞ optimal theory. The difficulty to compute the infimum of H∞-norms of recovery matrices in the set of all possible gains of decentralized observers is avoided.

基于H∞理论，将多变量系统的回路传递再生方法推广于分散控制关联大系统，并避免了在所有可能的分散观测器增益构成的集合上，直接计算再生矩阵的H∞范数下确界的困难。
