(UFO)不是說不明飛行物?

我只知道：UFO=Unidentified Flying Object。而飛碟，我覺得只是比較“族”的講法。

附加資料：
Unidentified Flying Objects 簡稱為UFO，是出現在天空或地面附
近的一種奇異的光或物體，我們還不知其由來。某些人相信它是來自其他行星的太空船，有的人以為UFO之出現乃自然現象。即使是科學家也無法解釋所有的UFO報告。

至於LAC，我倒未曾聼過。Search過，但沒什麽發現。只得了以下資料，但好像跟UFO沒什麽關係。

Wikipedia, the free encyclopedia（維基百科）：
Lac
Lac is the scarlet resinous secretion of a number of species of Lac-producing insects, the most commonly cultivated of which is Kerria lacca.[1]

The lac-producing insect is also known by numerous synonyms such as Laccifer lacca, Carteria lacca and Tachardia lacca. Kerria lacca belongs to the lac insect family Kerriidae, one of some 28 families of scale insects and mealy bugs comprising a large group of about 8000 described species of plant sucking insects, a few of which produce similar natural products (e.g., cochineal and crimson). Thousands of these tiny insects colonize branches of suitable host trees and secrete the resinous pigment. The coated branches of the host trees are cut and harvested as sticklac.

The harvested sticklac is crushed and sieved to remove impurities. The sieved material is then repeatedly washed to remove insect parts and other soluble material. The resulting product is known as seedlac. The prefix seed refers to its pellet shape. It is used in violin and other varnish and is soluble in alcohol. This type of lac was used in the finishing of 18th century fowling guns in the US. Seedlac which still contains 3-5% impurities is processed into shellac by heat treatment or solvent extraction.

Lac production is found in Assam and other parts of North-East India, Bangladesh, Myanmar, Thailand, Laos, Vietnam and parts of China. It is also found in Mexico.

U.F.O.=Unidentified Flying Objects，而LAC，則恕小弟孤陋寡聞，未聽聞過。
