构造上的

Basing on analysis movement rule of celestial body,the author discuss the cause of earth' s special structure formation and the evolvement law,who cites the theorys of gravitation, electromagnetic force, mightiness and acrotism.

本文在分析天体运动规律的基础上，运用引力、电磁力、强力和弱力等四种基本相互作用力的原理，探讨了地球特殊构造的成因和演化规律。

This method utilizes the invariant properties of affine geometry to calculate the affine invariant, which has a more fast process speed.

该方法利用仿射几何中的特征区域面积比的不变性质构造仿射不变量，在处理速度上具有较为明显的优势。

Compared with the invariant features of single parameter group, entirely global affine invariant features are more applicable, and chapter 4 introduces a new global affine invariant feature extraction method called EC-ARC, which is based on the invariance in affine geometry.

然后，提出了扩展质心(Extended Centroid， EC)和仿射区域划分(Affine Region Cutting， ARC)的新概念，并在EC和ARC的基础上，结合仿射几何性质，提出了构造具有完全仿射不变性的特征提取方法EC-ARC。

The ambiguousness of domain expert knowledge is taken into account, and fuzzy mathematics is applied to describe qualitative knowledge and to construct fuzzy rule.

在知识表示模式的基础上，考虑工艺知识的模糊性，本文应用模糊技术描述工艺领域中的定性知识，构造了模糊规则。

Among them the fault-lithology reservoir type is the most ,second is fracture reservoir,the least is fault reservoir,oil and gas distribution is mainly situated near or tip of the nose of Shangjia nosing structure. The relationship of oil and gas distribution is complex, dominately controled by sandbody and fault connection and the continuity of sandstone .

其中以断层—岩性油气藏最多，其次是断层遮挡油气藏，最少是断块油气藏，油气分布在平面上主要在尚家鼻状构造的鼻尖部位及其附近，油水分布关系复杂，主要受砂体与断裂沟通情况及砂体分布连续性的控制。

We show that, up to automorphisms, there is exactly one non-primitive connected arc-transitive graph on Z〓×Z〓 when the action of K on some B〓 is not faithful.

在此基础上，我们并对p〓阶连通弧传递循环图进行了完全分类，证明了在同构意义下，p〓阶连通弧传递循环图只有三个，而且这三个图的构造都是完全清楚的。

Based on quadratic congruences, a family of codes which have large capacity, good auto-correlation and cross-correlation properties is constructed in frequency domain.

在二次方一致性的基础上，构造了一种容量大、自相关和互相关特性好的码族。

In Southwest China, carbonate rocks are mainly distributed along the NE-extending tectonically upheavedzone, deeply impacted by geological background.

中国西南岩溶石山区岩溶发育的地质历史背景，决定其碳酸盐岩主要分布于NE向的构造隆起带上。

As a concrete example for the 3D timelapse seismic problem, a localized inversion algorithm is designed based on the continuous and recursive methods.

以三维时间推移地震为例，在连续型及逐次递归算法的基础上构造了快速的局域化反演算法。

Since Eogene, amount of tectonic subsidence has a characteristics of becoming litthe gradually from south to north , depositional centre is migrated from south to north, volcanic activity is stronger in south and weaker in north during Kongdian stage, and inverse during Neogene.

自早第三纪以来，构造沉降量具有由南向北由大变小的特点，沉积中心也是由南向北迁移的，火山活动在孔店期时南强北弱，到上第三纪时则是北强南弱。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
