The samples were made on the substrate of the hard aluminum alloy LY12 or the steeel 45# with wearresistant coating. The erosive wear resistances of the samples were investigated by the sand blast test using the Al2O3 sand with partical size of 1000 μm as the erodent.

喷砂试验选用粒径为1000 μm 的Al2O3颗粒为磨料，对LY12硬铝合金与45#钢为基底的仿生耦合试样进行试验。

Ever since the first proposal of the presence of β\|Fe in 1885 by Osmond, a great debate on the cause of quench hardening of steels was going on until 1922 when Westgren and Phragmén disproved the presence of β\|Fe by high temperature X\|ray diffraction analysis.

自从Osmond在 1885年首次提出β Fe以为，直到 192 2年Westgren和Phragm啨n用高温X射线衍射证明β Fe与α Fe有相同的体心立方结构为止，在很长时间内，冶金学家一直为钢为什么在淬火后变硬而争论不休。

Nearly impenetrable abalone shells, flexible and patchy butterfly wings, spider threads more rigid than steel, unwettable and self-cleaning lotus leaves, and the skin of dolphins are some examples of products of natural design prepared not by conscious manipulation but by spontaneous, self-organizing processes of nature—and still without comparable counterparts in any laboratory.

几乎坚不可摧的鲍鱼贝壳，灵活、片状的蝴蝶翅膀，比钢更硬的蜘蛛丝，具有防水和自我清洗功能荷叶，海豚的皮肤等都是一些天然设计的产品，它们的制造不是自觉的操纵，而是自然界通过自发、自行的过程来完成的，而至今任何实验室的产品也无法与其比拟。

The disks are subject to constant wear and therefore have to be replaced every 400／600 kg of coffee;the amount varies according to the type of coffee used(the Robusta varieties are harder and woodier).the type of steel and the diameter Of the disks.

这两个圆盘会持续磨损，因此每磨400-600kg咖啡就要换掉，这个数字由所用的咖啡的品种而有所变化(比如罗布斯塔就会更硬些)，也会由圆盘采用的钢的种类，以及圆盘的直径而有所变化。
