Athena's name is possibly of Lydian origin.It may be a compound word derived in part from Tyrrhenian "ati", meaning "mother" and the hame of the Hurrian Goddess "Hannahannah" shortened in various places to "Ana". In Mycenaean Greek, She possibly appears in a single inscription in the Linear B tablets: A-ta-na-po-ti-ni-ja /Athana potniya/ appears on a text from the Late Minoan II-era "Room of the Chariot Tablets" in Knossos, the earliest Linear B archive anywhere.

雅典娜这个名字可能起源于利底亚，它是由第勒尼安语中的"ati"和胡里安人的女神"Hannahannah"名字的简化"Ana"拼合而成，在迈锡尼文明时期，起源于米诺斯王朝后期，位于科诺索斯的"战车铭文之室"的一则铭文中，雅典娜也许是以"A-ta-na-po-ti-ni-ja /Athana potniya"这个名字出现的。

Electroless Co-Ni-P thin film as-deposited was amorphous possessing smooth surface. The film was crystallized after heat treatment at 300℃ for 1 hour, and the surface of film was composed of "taper humps". When the film was heated, phase of Co2P deposited from the solid solution and allotropic transformation took place from hexagonal close-packed system to face-centred cubic lattice.

摘 要：化学镀Co-Ni-P薄膜镀态下为非晶态结构，表面较为平整；经300℃×1h热处理，发生了晶化转变，表面由"圆锥峰"所构成；随加热温度的提高，镀层析出了Co2P相，并发生了由密排六方结构的α-Co向面心立方结构的β-Co的同素异构转变。
