分子吸引力

When water is confined in tubes of very small bore, the forces of cohesion (the attraction between water molecules) are so great that the strength of a column of water compares with the strength of a steel wire of the same diameter.

当水被限制在内径很小的管道中时，内聚压力(水分子之间的相互吸引力)是如此之大以致一支水柱的强度相当于一根直径相同的钢丝的强度。

With its basis on city attraction-φ and adoption of surface tension in physics, a math model about the floating population in city is established in this paper. This model takes the coacervation and escape of the molecule as the inflow and outflow of the population, the electric field intensity as the policy, and the electric conductivity in electrolytic solution as the enforcement of the policy.

以φ-城市吸引力为依据，借用物理学中"表面张力"的概念，把分子的凝聚和逃逸理解为人口的流进与流出，把电场强度理解为城市的政策、法规、法令，把电解溶液的电导率理解为对政策、法规、法令的执行情况，建立了城市流动人口的数学模型。

For Luddites like myself, who are as interested in the edibility of their cupcakes as the attractiveness, there is definitely useful information.

像我这样的勒德分子，谁是在作为他们的蛋糕可食性的吸引力有兴趣，有一定的有用信息。

molecular distillation, separation, average free path of molecular movement

当两分子离得较远时，分子之间的作用力表现为吸引力，但当两分子接近到一

The attraction force is different from three Van der Waals forces, it exists in any combination of polar molecular and nonpolar molecular.

这种吸引力不同于已知的三种范德华力，又存在于极性分子和非极性分子的各种组合中。

Balloon to overpower the repulsive force between the negative ends of the water molecules and the balloon .

这是由于：水分子带正电荷的一端与气球之间的吸引力大于水分子带负电荷的一端与气球之间的斥力。

Because a molecular is the rotatable charge group, there is an attraction force between molecules.

因为分子是能自由旋转的电荷群，所以分子之间存在相互吸引力。

The so-called volatilize refers to liquid liquid molecular energy detachment and Intermolecular attraction escaping procedure.

所谓挥发，是指液体分子能量达到脱离液体分子间吸引力而逸出的过程。

Because of little and not well-distributed suction power of gas molecule to liquid molecule, there is surface tension between the liquid and gas in alveoli(a kind of suction power or concentric force souced from surface).

肺泡内液气界面存在着表面张力（一种表面能来源与分子间的吸引力或内聚力），是由于气体分子对肺泡内面表面液气分子吸引力很小，液体分子各向受力不匀的表现。

Germ warfare is an attractive terrorist option. After all, it is hard to prove or disprove what the terrorist claims to be able to do. Because germ agents are unseen, a tiny amount of agent has the potential to terrorize and disrupt the lives of millions. Imagine the terrorist who telephones a national newspaper to say that ten phials of nerve agents or hazardous viruses will be added to one of the thousands of distribution points of our domestic water supply. Over 30 million adults would be boiling all drinking water for weeks-especially if one or two had died already.

细菌战是对恐怖主义分子很有吸引力的一项，毕竟，难以证实或否定恐怖分子所宣称的，因为细菌战是看不到，措不着的，一点点剂量就对数百万人造成潜在威胁和打乱他们正常生活，试想一下：恐怖分子给国家主办的新闻报纸打电话，声称他们已经把数十瓶神经药剂和危险的病菌洒入了当地居民的水源供应地的数千个取水点，那么3000万成年居民数周内都要把水煮沸才敢饮用---尤其是有1-2人已死亡的情况下。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
