The results show that the mean particle size of α-Fe2O3 monolayer is about 58 nm. There are characteristic bands at 568, 482 and 386 cm~(-1) in IR spectrum. The absorption of 375 nm in UV-Vis spectrum is the electron transition of ferric and oxygen atom.

结果表明，α-Fe2O3单层膜是由粒径约为58 nm的粒子排布而成，在568、482和386 cm-1处有特征红外吸收峰，在紫外区375 nm处存在明显的吸收，为Fe-O间的电子跃迁，其吸光度值与膜层数间的较好线性关系说明在一定的速度下挂膜，可以将氧化铁溶胶中的纳米粒子较好地转移到基片上。

The answer given by Coulomb's experiment is that this dependence on distance is the same as in Newton's law of gravitation and Coulomb's law of electrostatics.

我们又一次看到在这个理论中应用了一般的观点，即倾向于用引力和斥力只与不变的粒子之间的距离有关，而且只作用于粒子之间来解释一切现象。

Also, in quantum mechanics, the use of the term particle refers to an elementary or subatomic particle.

同样在量子力学里，使用术语粒子指的是一基本或亚原子粒子。

On the basis of introduction of the elementary principles and features of Particle Swarm Optimizational- gorithm,a new multi-thresholds segmentation method based on PSO is proposed.

在对粒子群优化算法的基本原理和方法进行简要概述的基础上，提出了一种基于粒子群的多阈值图像分割算法。

A local elitist particle strategy is introduced in order to avoid being trapped in local optima.

采用局部精英粒子优化策略解决了粒子群算法易陷入局部最优的问题。

During 1899, Germany scientists Elster and Geitel discovered the particle in the air did carry with electrical, and this kind of particle was called the "Air ion".

在1899年，Elster和Geitel这两位德国科学家首次发现空气中含有带电的粒子，此粒子后来被称为「空气离子」。

He outlines how the Higgs field, which is thought to be responsible for endowing matter with mass and thus enabling gravity to act on it, may also be a collective property. Physicists are engaged in the biggest scientific experiment in the history of the world at CERN, the European particle physics laboratory, in an attempt to find the particles associated with this field and thereby confirm its existence.

他认为希格斯场（人们认为希格斯场赋予了物质以质量，从而万有引力可以作用于物质之间）可能也有其它物质相伴，并对验证过程进行了简要描述；物理学家正在CERN的欧洲粒子物理试验室里进行史上最大规模的实验，为的是找到和希格斯场关联的粒子，从而确定希格斯场的存在。

Thermodynamic calculating showed that reduced glutathione adsorbed on core-shell structure SiO_2/γ-Fe_2O_3 magnetic nanocomposites was an endothermic spontaneous、 entropy increasing and endothermal process .

还原型谷胱甘肽在该复合粒子上具有较大的吸附量，是一个多层吸附过程；热力学计算说明还原型谷胱甘肽在核壳结构SiO_(2/γ)-Fe_2O_3磁性纳米复合粒子上的吸附是一个自发的、熵增的、吸热过程。

Based on Voyager 1's magnetic field and energetic particle observations, and our knowledge of solar wind shocks, it is inferred that the bulk velocity of the solar wind must have also dropped suddenly when Voyager 1 crossed the TS.

在旅行者一号关于磁场强度和高能粒子的探测数据的基础上，我们原先关于太阳风的知识受到了极大挑战，由它推断，大部分太阳风粒子的速度在旅行者一号穿过终端激波时肯定也急剧降低。

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。
