In this dissertation, based on glass microspheres and submicron silicon dioxide, the silver-coated core-shell shielding particles were prepared by liquid phase chemical deposition and layer by layer packing technology. The influences of the preparation conditions on the structure of the synthesized core-shell particles were also systemically studied. The conclusions are enumerated as follow:(1) Monodispersed submicron silicon dioxide spheres in the size range of 250～550 nm are synthesized by Sol-Gel method using ammonia as catalyst.

本文在前人研究的基础上设计出以微米级玻璃微珠为基核，采用液相化学沉积法和层层包裹法制备表面包银的核壳粒子电磁屏蔽剂，并对液相化学沉积法和层层包裹法的制备工艺进行了系统研究，取得了以下主要结论：(1)以氨水作催化剂，采用溶胶－凝胶法制备了粒径分布在250～550 nm之间的二氧化硅微球。

At the role of centrifugal force, the liquid was thrown from the impeller center and outer edge of the energy leaving the impeller at high speed into the outer pump shell-shaped cochlea.

Stadium in reinforced concrete structure coated with a shell limestone powder, Oval bleachers in the west side of the marathon action opened the door through May People's Assembly Square, Construction of the unique characteristics is obvious.

体育场在钢筋混凝土结构上涂覆了壳灰岩粉，其椭圆形看台在西侧马拉松大门处分开直通五月人民大会广场，建筑的独特之处由此可见一斑。

Therefore, more electrons close to the core, the interaction between the electrons and the core more, and the self-energy more.

所以与核靠近的壳层上的电子越多，电子与核内静电吸引的排斥力就越大，产生的自能修正就越大。

Thickness and density of defects lying in cross section of end bar is larger than in slot bar.

端部线棒剖面上的缺陷厚度和局部缺陷密度比槽部线棒大，分析认为热机应力是形成脱壳的重要原因，机械应力是形成分层的重要原因。

If in a single screw on the shell lined with hard rubber, can also be used for conveyor belt particles suspension.

若在单螺杆泵的壳内衬上硬橡胶，还可用于输送带颗粒的悬浮液。

The most interesting is the Lo dug on the beach: a snail, the appearance of abnormal smooth, very beautiful patterns, hidden in the sand, but as long as pay attention to crawl after it left a deep trough of curved lines, you can easily find It brought home a little processing, that is, a fine jewelry; another Lo is also long in the sand, white shell, the white meat, good taste, it will be on the beach in the arch of a small sandbags, as Chun-Sun unearthed, one out of a prospective, very interesting.

最有趣的是在沙滩上挖螺：一种螺，外表异常光滑，有非常美丽的花纹，藏在沙中，但只要留意它爬行后留下的很深的弧形槽线，就能轻易找到它，带回家略为加工，即是精美的饰品了；另一种螺，也是长在沙中，白色的壳、白色的肉，味道极好，它在沙滩上会拱出一个小沙包，像春笋出土那样，一掏一个准，非常有意思。
