粉末

The results of XRD (X-ray diffraction), SEM show that the Al-Cu-Fe quasicrystalline coating is dense and uniform, by preparing from Al70Cu20Fe10 powders with particle size of 325 mesh (4.5μm). After annealing under vacuum condition of 800℃ for 2 hours, it is observed that the icosahedron phase is the major phase together with a few β-Al phase.

由X-射线衍射XRD(X-Ray Diffraction)、扫描电镜SEM分析得出：采用原子比为A170Cu20Fe10、粒度为-325目的粉末制备的涂层，在800℃下真空退火处理2h后，结构均匀致密，二十面体准晶相含量高，并只含有少量的β相。

We choose dicyandiamide and 2-ethyl-4-methyl imidazole as curing agent.

研究结果表明可以在未加表面分散剂的条件下使得粉末能均匀分散在基质中。

Adjoining the Powder Mills, there is a good specimen of Chinese architecture called the Haikwang Temple, and which is given in our view ; its bell tower has a prominent position being considered a work of great merit : many of these small Temples are built by funds accumulated through the .fanatic zeal of poor creatures who voluntarily Immure them

在粉末厂旁边，有一座华丽的中国式建筑，它被称为海光寺。图中所显示的是处于庙宇显要位置的钟楼，它被用于表彰兴建庙宇的伟大的功绩。这类小庙宇的兴建多来源于很多并不富裕的信徒的捐资，他们希望借此表达虔诚。

The results show that the hardness of composites fabricated with vaporizing impregnant process is much higher than that fabricated with mixing nano sized powder process.

结果表明在填料含量相同时，溶剂蒸发法制备的PTFE复合材料的硬度显著高于固体纳米粉末混合法制备的PTFE复合材料的硬度；使用纳米颗粒作填料时，用偶联剂处理表面对硬度没有显著影响。
