粒子

This has something to do with its single evolution strate- gy because too single evolution strategy makes the swarm homoplasy.

这与粒子群采用单一的进化策略有关，因为过于单一的进化策略使粒子群整体上有一种趋同性。

The spacecraft's sensitive spectrometer was able to register the chemical signatures not only of water vapor but also of hydrogen cyanide, carbon monoxide, and carbon dioxide--all precursors of the more complex molecules that scientists think eventually gave rise to life on Earth.

斯必泽太空望远镜上敏感的光谱仪不但能够记录水蒸气的化学特征，还能够记录氰化氢、一氧化碳和二氧化碳的化学特征，这些都是更为复杂分子的初级粒子，科学家们认为是这些初级粒子最终导致了地球生命的产生。

LaNi〓 can be easily activated at room temperature and activated LaNi〓 possesses catalysing effect for the dissociation of H〓, which greatly reduces the energy barrier for dissociation of H〓. Hydrogen passed through LaNi〓 particles, then diffused into the crystal lattices of V、Nb and TiFe alloy and formed hydrogenate.

LaNi〓粒子在室温下很容易活化，活化后的LaNi〓具有了氢分子分解为氢原子的催化作用，降低了氢分子分解为氢原子所必须克服的势垒，氢通过LaNi〓粒子而进入V、Nb、TiFe合金晶格中，形成金属氢化物。

A fuzzy logic system for classification of hydrometeor type based on polarimetric radar measurements is described.

根据不同相态降水粒子的散射和空间取向等特征建立了基本形式为不对称的T型函数的模糊逻辑识别的隶属函数，完善了该识别方法的流程，并利用美国KOUN雷达的观测资料，详细讨论了利用双线偏振雷达观测资料识别降水粒子相态的方法，并对其在实际业务运用中的合理性和可行性进行分析探讨。

In the hydrometer analysis, the "size" of a particle is the diameter of a sphere which settles in water at the same velocity as the particle.

在比重分析中，粒子的"大小"是和粒子以同等速度在水中下沉的球体的直径。

Due to surface modification, the size of CdS nanoparticles is easily controlled, and the obtained hydrosol or organic sol is more stable.

由于表面修饰，使得CdS纳米粒子的尺寸易于控制，所得水溶胶或有机溶胶更加稳定，还能够得到可再分散的纳米粒子粉末。

Particles with icosahedral form were observed in the SEM images.

SEM观测到样品中有类二十面体结构轮廓的粒子，这些粒子尺寸为百纳米量级，具有自相似结构。

After the immunoreaction,the colloid gold aggregated to form a network,which could change the optical property of themselves in the reaction system.

随着癌胚抗原量的增加，抗原与胶体金粒子标记抗体的反应量不断增加，网络结构也越来越大，使得胶体金粒子在646 nm处的吸收值不断增加。

It is revealed that with increasing incidence angle, the penetration depth decreases and the join strength is weakened.

结果表明：随着粒子入射角度的增大，侵彻深度逐渐减少，粒子与基体的结合强度逐渐减弱。

There are different views about the genesis of nano-sized particle layers in rocks, and we incline to the view that shear friction plays a dominant role and that the nano-sized particle layer may be called a frictional-viscous thin layer.

对岩石中纳米粒子层的成因有着不同的观点，我们倾向于剪切摩擦的主导作用，纳米粒子层可称谓摩擦-粘性薄层带。

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。
