由于纳米粒在肿瘤靶向性方面的优势和大粒径中空粒子优良的沉积性能，大粒径中空纳米聚集体在干粉吸入剂上具有独特的优势。

Original porosity is typified by the intergranular porosity of sandstones and the intercrystalline and politic porosity of some limestones.

原生孔隙度以砂岩粒间孔隙度和某些石灰石的晶体粒间和鲕状孔隙度为代表。

原生孔隙度以砂岩粒间孔隙度和某些石灰石的晶体粒间和鲕状孔隙度为代表。

The observation under microscope, the analysis of Au. Ag. Cu. Fe. As content by electron probe and the micrograph of gold grains, confirm that placer gold are natural Au-Ag alloys. The structure and chemical compositions of verge and interior of gold grains differ significantly for large grains but little for small grains and those which intergrow with guartz and limonite.

镜下观察、电子探针分析(Au、Ag、Cu、Fe、As含量)及显微照相等研究，证实了砂金是天然Au-Ag合金，其边部与内部的结构、成分具有不均一性，这在中粗粒金中表现尤为明显，而细粒金及带连生体的金常常不具备这一特点。

The experimental results showed that SiC ultrafine powder was synthesized at 1500℃for 120 minutes by used rare earth lanthanum as additive. Its primary particle size was about 100nm and aggregated particle size was about 360nm and the particle shape was regulation, non-aggregation and well dispersibility. While the rare earth ceria used as the additive, SiC ultrafine powder was synthesized at 1500℃for 150 minutes but the particle shape was irregulation and seriously agglomerated and had numerous crystal whiskers.

实验结果表明：以稀土镧为添加剂时，在1500℃×120min合成工艺下，可以合成出一次粒径为100nm左右，二次粒径为360nm的SiC细粉，且SiC粉体颗粒形状规则，无团聚，分散性好；以稀土铈为添加剂时，在1500℃×150min合成工艺下，也可以得到单相的SiC，但SiC粉体颗粒形状不规则，有大量晶须存在，且团聚严重。

The nighthawk circled overhead in the sunny afternoons —— for I sometimes made a day of it —— like a mote in the eye, or in heaven's eye, falling from time to time with a swoop and a sound as if the heavens were rent, torn at last to very rags and tatters, and yet a seamless cope remained; small imps that fill the air and lay their eggs on the ground on bare sand or rocks on the tops of hills, where few have found them; graceful and slender like ripples caught up from the pond, as leaves are raised by the wind to float in the heavens; such kindredship is in nature.

而在这艳阳天的下午，夜鹰在我头顶的上空盘旋，——我有时整天地工作，——它好像是我眼睛里的一粒沙，或者说落在天空的眼睛里的一粒沙，它时而侧翼下降，大叫一声，天空便好像给划破了，最后似裂成破布一样，但苍穹依然是一条细缝也没有；空中飞着不少小小的精灵，在地上、黄沙或岩石上、山顶上下了许多蛋，很少有人看到过的；它们美丽而细长，像湖水卷起的涟漪，又像给凤吹到空中的升腾的树叶；在大自然里有的是这样声气相投的因缘。
