样品分布

By using single point, linear and lateral scanning, the elements composition and distribution in samples can be studied in micrometer scale.

同时利用微束扫描分析可获得样品中元素的点、线、面分布信息。

Precious metals tend to occur as scattered particles randomly distributed, so a large sample of ore is required.

贵金属因分散颗粒无规则地分布，分析时需要取用大量矿石样品。

Briefly, tissue samples were homogenized in 5% 5-sulfosalicylic acid and centrifuged at 18 000 3 g for 5 min.

简而言之，组织样品在5%的5-磺基水杨酸中成均匀分布微粒并以180003g离心5分钟。

According to the observation of the number concentration spectrum and the mass concentration of atmospheric aerosol, TSP and its particle size distribution,micrometeorology,and the solar spectroscopic radiation,even the neutron activation treatment of sand dust samples in Helan Mountainous area, the formation law of sandstrom, dust and sand blowing weather and the characteristics of climatic variation in this area and the influence of Helan Mountain are counted and analysed.

利用贺兰山地区沙尘暴历史资料和综合观测资料，对大气背景、浮尘、扬沙和沙尘暴发生期间的大气气溶胶数浓度谱、质量谱、大气总悬浮颗粒及粒径分布、微气象、分光日射观测以及沙尘样品进行中子活化处理，分析了该地区浮尘、扬沙和沙尘暴形成规律，气候变化特征和贺兰山的影响。

The variation of magnetic properties is interpreted by the three-sublattice Yafet-Kittel model.

此外，还讨论了离子分布对超精细磁场变化的影响，并利用Yafet-Kittel模型对样品的磁性变化进行解释。

The shift in the peak extinction wavelength and the change in the corresponding intensity of the LSPR band as a function of the refractive index of the solution are 71 nm/RIU and 0.21 a.u./RIU, respectively. The penetration depth of the electromagnetic field excited by LSPR upon the response of the sensing film is estimated to be about 16 nm.

研究结果表明，所制备的LSPR传感膜粒子分布均匀、单分散性好、稳定性高、重现性好；消光峰位对样品溶液折射率的检测灵敏度为71 nm/RIU，相应的峰强检测灵敏度为0.21 AU/RIU，对表面吸附层的渗透深度约为16 nm。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
