X particle

A stable nanometered TiO_2 colloids were prepared from the hydrolysis of titanyl organic compounds by controlling the reaction conditions. The X-ray diffraction and scan electro microscopy ( SEM) revealed that the colloidal TiO_2 was in an anatase crystalline particle form with a diameter of 12 nm.

控制钛氧有机物水解条件合成稳定的纳米二氧化钛胶体，X射线衍射和扫描电子显微镜研究表明，该胶体的胶粒为锐钛矿型晶体，晶粒大小约12nm。

High-resolution studies of aluminum K α x-rays produced by proton and α-particle at the beams energy 0.666MeV/amu have been performed with a curved crystal spectrometer.

本文用高分辨弯晶谱仪对0.666MeV/amu的质子和α粒子激发Al的Kαx射线进行了研究。

The dependence of x on particle size and drying rate could be attributed to the competing effects of the dominant characteristic time of particle-phase diffusion of water and diffusive movement of NaCl monomers, coupled to system size.

NaCl形状因子χ随粒径和干燥速率的变化主要取决于颗粒相水的扩散运动和NaCl单体运动的特征时间的相互竞争，以及体系大小的影响。

These tools include the alpha particle X-ray spectrometer ( apxs), which measures elemental composition, and the Mars hand lens imager close-up camera, or Mahli.

这些设备包括阿尔法粒子x光分光仪，其可以检测元素组成，以及火星手持透镜成像器近景摄像机，或简称mahli。

The samples were characterized by laser particle size analyzer, X-ray diffraction instrument, chemical analysis and so on.
