内聚力

Refrigeration of boiled water nature comes to 20 ℃ when 25 ℃, before the gas of deliquescent amid compares boiling, decrease 1/2 the left and right sides, water quality also produces change subsequently, cohesive force increases, between element and element more close together, exterior tension is strengthened.

开水自然冷却到20℃至25℃时，溶解在其中的气体比沸腾前减少二分之一左右，水质也随之发生变化，内聚力增大，分子与分子之间更加紧密，表面张力加强。

New ideas and methods in the paper:1 The formulas on perforated casing collapse strength were deducted, which offereda convenient method to analyze the relationship between casing collapse strength and perforation;2 The stress and displacement formulas on the system of casing, cement anddeformation under the non-uniform load were deducted, which offered the theoretical found for designing optimally casing string;3 The relationship between structure in-situ field of whole oil field and casing failurewere studied, which offered the scheme for the prediction of casing failure. The process of study in the paper:1 For simulating the relationship between the structure in-situ field and the casingfailure in the oil-deformation, the tests of the uniaxial tensile, compress, tnaxial compress and dilatability were made on the samples of the drill cores from deformation of casing failure position in Yuejing II oil field.

本文的主要创新： 1推导出了射孔套管抗挤强度的解析式，为分析射孔与套管强度的变化关系提供了简便的方法； 2推导出了非均匀地层载荷作用下套管、水泥环和地层组合体的应力和位移解析式，并非均匀作用下套管柱优化设计提供了理论依据； 3研究整个油田区块构造应力场与套管损坏关系，为预测套管损坏提供了可行方案；本文的研究过程如下： 1为模拟构造应力场与油层段套管损坏关系，做了大量的岩石单轴抗拉、单轴抗压、三轴试验以及岩石遇水膨胀试验，获得了研究区块岩石的弹性模量、泊松比、内聚力、内摩擦角以及岩石的线膨胀系数，这此数据为本文研究油层段套管损坏机理研究的理论分析和有限元法提供了实验数据。

This disjunction of morals has weakened the moral cohesion and mobilization in the society.

正是这种道德脱节现象导致了道德社会内聚力和社会动员力的减弱，出现了社会成员行为缺乏明确的规范约束力，甚至呈现出某种混乱与无序的局面。

But because have some of high polymer,many plasticizer is contained in soft goods, in side and bottom stick in receiving a process, plasticizer sticks the ooze that receive a dose to move through contacting a bound to face, return some high polymer epispastic material is low surface can, cause stick the cohesive force that receive a dose to reduce, affect adhesive strength greatly.

但由于有些高分子软制品中含有大量的增塑剂，在帮和底的粘接过程中，增塑剂通过接触界面向粘接剂渗移，还有些高分子发泡材料是低表面能的，致使粘接剂内聚力降低，大大影响粘合强度。

If the soil sample contains an insignificant portion of particals smaller than 0.074mm, as is often the case with cohesion less soils and disintegrated rocks, the hydrometer 0.074 analysis can be omitted.

如果土壤样本中小于0.074毫米的颗粒部分微不足道（无内聚力的土壤和松散的岩石通常就是这种情况），就可以进行比重计分析。

The Bush administration never resolved this question in its own policies, and the consequence was incoherence and ineffectiveness.

布什政府从来没有在自己的政策下解决过这个问题，其后果就是无内聚力和毫无效率。

The slope stability question is influenced by many kinds of inherent factors, for instance geological structure, intensity of rock body, development state of joint and crack, cohesive force of the rock, interior angle of friction, groundwater, etc., these objective factors reflect generally their sizes with some quantitative parameter indexes in the past.

边坡稳定问题受多种内在因素影响，如地质构造、岩体强度、节理裂隙发育状况、岩石的内聚力、内摩擦角、地下水等，这些客观因素过去一般用某些定量参数指标来反映其大小。

In this paper, factor of influence on matal activity is expounded by studying ionization energy, Cohesive force, ionic hydration energy and cystal lattice energy of the compound.

本文通过对金属的电离能，内聚力，离子水合能以及形成化合物的品格能大小的研究来阐明影响金属活性的因素。
